TRUCK COMPONENTS AND SPECIFICATIONS Truck And Engine
Operator's Cab
The 930E-3 Dump Truck is an off-highway, rear dump truck with AC Electric Drive. The gross vehicle weight is 1,106,000 lbs. (501 673 kg). The engine is a Komatsu SSDA16V160 rated @ 2700 HP (2014 kW).
The operator cab has been engineered for operator comfort and to allow for efficient and safe operation of the truck. The cab provides wide visibility, with an integral 4-post ROPS/FOPS structure, and an advanced analog operator environment. It includes a tinted safety-glass windshield and power-operated side windows, a deluxe interior with a fully adjustable seat with lumbar support, a fully adjustable/tilt steering wheel, controls mounted within easy reach of the operator, and an analog instrument panel which provides the operator with all instruments and gauges which are necessary to control and/or monitor the truck's operating systems.
Alternator (GE-GTA41) The diesel engine drives an in-line alternator at engine speed. The alternator produces AC current which is rectified to DC within the main control cabinet. The rectified DC power is converted back to AC by groups of devices called "inverters", also within the main control cabinet. Each inverter consists of six "phase modules" under the control of a "gate drive unit" (GDU). The GDU controls the operation of each phase module. Each phase module contains an air-cooled solidstate switch referred to as a "gate turn-off thyristor" (GTO). The GTO cycles on and off at varying frequencies to create an AC power signal from the DC supply. The AC power signal produced by each inverter is a variable-voltage, variable-frequency signal (VVVF). Frequency and voltage are changed to suit the operating conditions. Cooling air for the control / power group and wheel motors, as well as the alternator itself, is provided by dual fans mounted on the alternator shaft.
AC Induction Traction Motorized Wheels The alternator output supplies electrical energy to the two wheel motors attached to the rear axle housing. The motorized wheels use three-phase AC induction motors with full-wave AC power. The two wheel motors convert electrical energy back to mechanical energy through built-in gear trains within the wheel motor assembly. The direction of the wheel motors is controlled by a forward or reverse hand selector switch located on the center console.
Suspension HYDRAIR®II suspension cylinders located at each wheel provide a smooth and comfortable ride for the operator and dampens shock loads to the chassis during loading and operation.
FAM0208
Power Steering The truck is equipped with a full time power steering system which provides positive steering control with minimum operator effort. The system includes nitrogen-charged accumulators which automatically provide emergency power if the steering hydraulic pressure is reduced below an established minimum.
Dynamic Retarding The dynamic retarding is used to slow the truck during normal operation or control speed coming down a grade. The dynamic retarding ability of the electric system is controlled by the operator through the activation of the retarder pedal (or by operating a lever on the steering wheel) in the operators cab and by setting the RSC (Retarder Speed Control). Dynamic Retarding is automatically activated, if the truck speed goes to a preset overspeed setting.
Brake System Service brakes at each wheel are oil-cooled multiple disc brakes applied by an all-hydraulic actuation system. Depressing the brake pedal actuates both front and rear brakes, after first applying the retarder. All wheel brakes will be applied automatically, if system pressure decreases below a preset minimum. The parking brake is a dry disc type, mounted inboard on each rear wheel motor, and is springapplied/hydraulically-released with wheel speed application protection (will not apply with truck moving).

FIELD WELDING FOR ASSEMBLY OR REPAIR When welding on Komatsu equipment, whether at initial field assembly or during normal maintenance repairs, special procedures must be followed. Due to the continuous program of research and development, periodic revisions may be made to this publication. It is recommended that customers contact their distributors for information on the latest revision. The welding information contained in this chapter is general information that must be followed unless otherwise specified in a detailed repair procedure provided on an engineering drawing or a detailed specific repair procedure. Additional specific information, or detailed instructions can be obtained through your local Komatsu customer support manager.
WELD PROCEDURES Electric arc welding, either the semi-automatic “MIG” (GMAW), Flux Core (FCAW), or “Stick” electrode welding (SMAW), are approved processes for field installation and maintenance welding. Welding of highly stressed structural members such as castings, torque tubes, top and bottom plates on the frame rails, and the curved intersection points of frames should be done with the specific detailed instructions from Komatsu Product Service. See Annex A for repair procedures. These repair procedures are detailed instructions for most high stressed structural members.
APPROVED CONSUMABLES WELDER QUALIFICATION AND TRAINING
GMAW - LW102-15 or ER80S-D2
The welding technique must be of the highest standard to produce the soundest weld possible. Only welders who have been trained and qualified for structural steel welding in all positions, in conformance with the American Welding Society (AWS) D1.1 or (AWS) D14.3 only, are allowed to perform the welding. The welding instructions for field assembly of Komatsu components are normally provided by engineering drawings. Additional detailed welding instructions for field repairs are provided in the field repair manual SEB14001. A full understanding of the AWS standard welding symbols is necessary to perform and inspect such field welds. Weld sizes specified on the drawings are intended to reflect minimum requirements.
SMAW - E7018-1, E8018-C1, or E8018-C3
FCAW - E70T-5, E71T-8, or E71T8-NI1
WELD QUALITY REQUIREMENTS 1. Each weld must be homogeneous with low porosity, free from cracks, and slag inclusions. 2. Each weld must have complete fusion between the base metal and weld metal added by the electrode. 3. All welds must be reasonably smooth, without excessive deformity, and all craters filled. No cracks are permitted. 4. The toe of a weld to a stressed member must have a smooth transition. Excessive convexity in multi-pass fillet welds is not permitted. Excessive convexity produces high residual stress in the throat of the weld, and is not permitted. 5. Undercut in excess of 0.8 mm (0.03 in.) on critical welds must be reworked by the application of welding an additional cover pass. It is important that this pass is blended with the existing weld.
FAM0403
Field Welding Procedures
4-1
6. When welding in the vertical position, always weld using the vertical up technique. Large wash weld weaves should not be used when welding on truck frames. Properly applied multiple pass welding is the required procedure on truck frames.
2. Low Ambient Temperature - DO NOT weld in temperatures below 50°F (10°C). At low temperature conditions, preheating of all welding joint work areas is required. See preheat and post heating requirements as detailed in Annex A.
7. Slag is to be removed from all weld beads, and must be completely removed before each pass in a multiple pass procedure. It is also required that all slag is removed and tie in all areas. Grind all welds where a weld crosses or intersects with another weld.
3. Weld Cooling - Protect the weld area from a rapid cooling rate. Heat retardation may be accomplished through the use of heat lamps, torches, insulating blankets, etc.
MATERIALS, CONTROLS, AND PRECAUTIONS The steel used in the fabrication of all Komatsu equipment is of high strength low alloy (HSLA) material of different grades. The standard dump body main plates are made from abrasion resistant materials. These materials offer themselves very well to welding during fabrication, and repair. The welding consumables are often supplied by Komatsu America Corp. with the new equipment as part of the field welding / assembly package. For field welding and repairs, the approved consumables as detailed, should be procured from a local, reliable supplier. Other highly specialized welding consumables are available but have limited use on Komatsu structural components. Approval is required from your Komatsu customer support manager.
4. Moisture - Any moisture on the steel surfaces to be welded must be removed before welding. Electrodes must be stored in sealed containers until needed. Electrodes must be kept in a warming oven at the work location until used to prevent any moisture absorption which might affect weld quality. 5. Foreign Materials - Any foreign substances (dirt, paint, rust, scale, and carbon deposits from cuttings) must be removed prior to welding. Clean all weld areas and surfaces with a grinder to ensure that all foreign materials have been removed.
WELD INSPECTION
Control of the welding area environment is essential for producing proper and sound welds. Essentially, five areas require attention and control.
All welding repairs are subject to inspection by a Komatsu appointed inspector or laboratory to insure quality. After the weld has been made it can be inspected by a number of non-destructive evaluation techniques. The inspections can include any of the methods listed below. All assembly welds and weld repairs that are deemed unacceptable by the inspector must be corrected at no additional cost to Komatsu. All weld repairs are also subject to additional inspection.
1. Air Movement - Avoid areas where air movement from wind, drafts, or blowers is prevalent. This is particularly important when a shielding gas is being used as part of the welding process.
1. Visual Inspection - This is the process of looking for potential defects such as undersized welds that can be checked with weld gauges for, surface cracks, surface porosity, craters, and undercuts.

FAM0403
RECORDS 2. Dye Penetrant Inspection - This is an easily applied process which indicates cracks or surface conditions. The process is relatively inexpensive, but does not produce a permanent record except by normal photography. 3. Fluorescent Penetrant Inspection - Similar to dye penetrant inspection. This process uses a black (ultraviolet) light for increased efficiency and accuracy. 4. Magnetic Particle Inspection - This process requires special equipment that is usually more costly than the dye penetrant inspections. This process does not provide a permanent record except by normal photography. 5. Ultrasonic Inspection - This is a popular method of examining weld discontinuities. Specialized equipment and operator certification is required. With some equipment printed data is available of the test providing a permanent record. Also, operator records with equipment settings and test results are normally recorded. 6. X-Ray Inspection - This process provides a view of the weld and base materials but it is highly specialized. This procedure provides a permanent visual record, but is more expensive than most other inspection techniques.
Komatsu requires record keeping of all welding work. This information is valuable when personnel or job conditions change. The service and warranty departments of Komatsu must be provided with inspection reports and photographs of the weld area before, during, and after the repair. The photographs must be clear and close enough to show the weld joint preparation complete, with backer bars installed, etc. just prior to welding. These photos easily identify if the required preheating and post heating have been done with a three inch circumference around the weld repair area. Without this documentation, Komatsu will not cover any weld repair claim made under warranty. No exceptions will be made.
ANNEX A The following are general repair procedures, which must be followed for all repair and rework of major load carrying members on Komatsu equipment. 1. The repair or rework area must be protected from wind and moisture during the entire procedure. If the repair work is to done outside additional precautions must be taken to protect the weld repair process from outside elements. All welding should be done at an ambient temperature of 10°C (50°F) or above. 2. Clean and grind the entire repair area to remove all rust, grease, oils, paint, and any other foreign materials likely to contaminate the weld.
FAM0403
Field Welding Procedures

3. Air arc the entire crack leaving a V-shape joint. The depth of the V (or U shaped) joint will be determined by the depth of the crack. The width to depth ratio should be approximately 1.25:1 and never less than 1:1. All cracks through the parent material will require a slightly wider root opening than the original, usually 6 mm (0.25 in.) to allow the installation of a backup strip. Backup strips are required for all cracks that have gone through the parent material and cannot be welded from both sides. If a weld repair allows access to both sides of the plate, no backup strip is required as long as complete weld penetration is achieved. If backup strips are not used, the surface profile on both sides must be ground smooth with no undercut. Documentation must support this repair. Photographs of surface condition are required by the service and warranty departments of Komatsu. 4. Use dye penetrant to ensure the cracks are completely removed. 5. After air arcing and inspections (Steps 3 & 4) all areas cut by the air arc should be cleaned thoroughly with a grinder to remove all possible carbon deposits and dye penetrant. 6. Fill gouges with weld and grind all surfaces smooth to avoid defects in the new weld. 7. Grind all surfaces to be welded so they are free of slag, rust, and any other foreign materials. 8. Preheat the entire weld joint area until the surrounding surface area reaches 150°C (300°F) at a distance of 76 mm (3 in.) from all areas to be welded.
4-4
9. All welds are to be made with approved consumables only. The SMAW (Stick) welding rod must be used within four hours after being removed from a new sealed container or from a 52°C (125°F) minimum drying oven. Any rod that exceeds this exposure time must be dried for one hour at 427°C (800°F) before being used. Keep all weld starts and stops to a minimum. 10. When the weld is complete, immediately (before the weldment cools) post heat the entire weld area to 150°C (300°F). Even if the area is over 150°C (300°F) heat must be applied to maintain this temperature for 15 minutes, and then allow it to cool slowly. In some cases this might require wrapping with insulation blankets. 11. Grind all butt-welded repairs smooth using 36 or finer grit grinding material. All grinding marks should be parallel to the direction of primary stress if possible (and if known). 12. Hammer peen the toes of repair fillet welds as detailed in Annex B, see attached. 13. Inspect repaired areas (for surface defects) using magnetic particle or dye penetrant inspection procedures. 14. If surface defects are found, remove all defects by grinding to a maximum depth of 1.5 mm (0.06 in.). Larger defects must be removed as per the above mentioned procedures. All spot welding also requires preheating and post heating.

Locate the GF cut-out switch in the access panel on the left side of the main control cabinet. Place the switch in the CUTOUT position. This will prevent the alternator from re-energizing and creating system voltage until the switch is returned to its former position. After repairs, replace all covers and doors and place the GF cutout switch and battery disconnect switches in their original positions. Reconnect all harnesses prior to starting the truck. Leave the drive system in the rest mode until the truck is to be moved. 4. If the red lights on the exterior of the control cabinet and/or the back wall of the operator's cab continue to be illuminated, a fault has occurred. Leave all cabinet doors in place. DO NOT touch the retard grid elements. DO NOT disconnect any power cables or use them as hand or foot holds.
Notify your Komatsu customer service manager immediately. Only qualified personnel, specifically trained for servicing the A/C drive system, may perform this service.
General Welding Guidelines 1. Open the battery disconnect switches and disconnect the battery charging alternator lead wire. 2. Disconnect all electrical harnesses from the Engine Control System (ECS). The ECS is located inside the electrical cabinet behind the operator's cab. Disconnect the ground strap from the ECS. 3. Fasten the welding machine ground (-) lead to the piece being welded. The grounding clamp must be attached as near as possible to the weld area. 4. DO NOT weld on the rear of the control cabinet! The metal panels on the back of the cabinet are part of the capacitors and cannot be heated. 5. DO NOT weld on the retard grid exhaust louvers. 6. Some power cable panels throughout the truck are made of aluminum or stainless steel. They must be repaired with the same material or the power cables may be damaged. 7. Power cables must be cleated in wood or other non-ferrous materials. DO NOT repair cable cleats by encircling the power cables with metal clamps or hardware. Inspect power cable insulation prior to servicing the cables and prior to returning the truck to service. Discard cables with broken insulation. 8. Protect power cables and wiring harnesses from weld spatter and heat. 9. DO NOT lay welding cables over or near the vehicle electrical harnesses. Welding voltage may be induced into the electrical harnesses and cause damage to components. 10. DO NOT allow welding current to pass through ball bearings, roller bearings, suspensions, or hydraulic cylinders.

GENERAL PRECAUTIONS AND INSTRUCTION 1. Clean and remove all foreign material from component mounting surfaces. Disconnect the battery cables before welding on the truck. Failure to do so may seriously damage the batteries and electrical equipment. Disconnect the battery charging alternator lead wire before welding on the frame or its components.
2. Mount the front suspensions first so that deck substructures can be installed while other components are installed.
Fasten the welding machine ground cable to the component being welded.
4. Install the fuel return hose on the rearward most fitting on the fuel tank.
DO NOT allow welding current to pass through bearings.
5. Torque the deck mounting bolts before the exhaust tubes, etc. are installed.
DO NOT lay welding cables over truck electrical cables and harnesses. Welding voltages could be induced into the truck wiring and cause damage to components.
6. Verify all electrical connectors are free from paint and/or corrosion. Clean any connector that may be questionable.
DO NOT weld on the fuel tank or the hydraulic tank unless they have been properly purged and ventilated. Maintain fire control equipment. Inspect fire extinguishers regularly to ensure they are fully charged and in good working condition.
3. DO NOT weld the front uprights until all upper decks are installed.
7. Do not torque the diagonal ROPS beam until after the operator cab & LH air intake tubes are in place. 8. Before installing the cab to the substructure, tap all threaded holes to remove paint. 9. Verify all wiring is properly connected before attempting to start the engine. 10. Recheck the torque on hardware installed at the factory. 11. Use blocks for charging the suspension (oil & nitrogen). Follow the procedures outlined in Section 10, Appendix.
Mark cap screws and nuts with paint or ink after tightening to the specified torque. This method provides verification that the hardware has been properly tightened.
12. Steering accumulators are normally not charged with nitrogen when shipped from the factory. Use proper precautions when checking the nitrogen pressure and oil level in the cylinder. 13. Brake accumulators are normally charged with nitrogen when shipped from the factory. Use proper precautions when checking pressures. 14. Verify the lube system is lubricated, purged and all levels full prior to start up. 15. Purge air from the steering pump before truck operation. Pressure will not build in the brake and steering circuit if air is present. Air in the system may damage the pump. Refer to the Hydraulic Checkout Procedure in Section 10 of this manual. 16. Use the battery disconnect switch when welding. Connect the weld ground near the weld area.

DUMP BODY ASSEMBLY GENERAL INFORMATION
The total weight of the body is approximately 30,362 kg (66,937 lb). Use two cranes for assembling the body. A 45 metric ton (50 ton) crane and a 109-136 metric tons (120-150 ton) crane are required. The larger crane is needed to help turn the body over after completion of the underside welding. Assembly of the body must be performed on flat terrain with an adequate area for welding machines and for maneuvering lifting equipment.
If the body is being welded in a cold climate, it is advisable to move the parts to be welded into an enclosed shop area. Surfaces to be welded must be dry and the temperature must be above 10°C (50°F). If shop space is not available, it may be necessary to provide a portable enclosure and pre-heat the parts prior to welding. In most instances, it is easier to assemble and weld the body while the sections are upside down. After the pivot, guide pin, and body pads are welded in place, the body can be turned over and the remainder of the assembly can be completed. All paint must be removed from surfaces to be welded. Use a wire brush or paint removal equipment. Refer to the assembly blueprints shipped with the truck for specific welding details and the parts required for assembly.
Body sections must be assembled as originally manufactured. Match the shipping numbers stenciled on the body sections to mate the correct parts. DO NOT mix components.

1. Body welding and chassis assembly must be completed before proceeding. Before the body is lifted off the ground, tie guy ropes to each of the four corners of the body for aiding in installation. There are two methods of installing the body depending on the cranes available. a. If the truck is operational and can be driven, two 50 ton cranes can be used, one positioned at either side of the body. The body can then be lifted high enough to allow the truck to be reverse propelled under the body (Figures 8-1, 8-2 & 8-3). b. If a large crane of approximately 150 ton is available, the body can be lifted over the chassis and installed in a similar fashion to that in Step a.

SUSPENSION OILING AND CHARGING PROCEDURE GENERAL
EQUIPMENT LIST
These procedures cover the oiling and charging of Hydrair® II suspensions on Komatsu 930E dump trucks.
•
Hydrair Charging Kit
•
Jacks and/or Overhead Crane
•
Support Blocks for: Oiling Height Dimensions (Front and Rear) Charging Height Dimensions (Front Only)
•
Hydrair Oil (See Specifications Chart)
•
Friction Modifier (See Specifications Chart)
•
Dry Nitrogen (See Specifications Chart)
Suspensions which have been properly charged will provide improved handling and ride characteristics while also extending the fatigue life of the truck frame and improving tire wear. NOTE: Inflation pressures and exposed piston lengths are calculated for a normal truck gross vehicle weight (GVW). Additions to truck weight by adding body liners, tailgates, water tanks, etc. should be considered part of the payload. Keeping the truck GVW within the specification shown on the Grade/ Speed Retard chart in the operator cab will extend the service life of the truck main frame and allow the Hydrair II suspensions to produce a comfortable ride.
Installation of Charging Kit Assemble the charging kit as shown in Figure 4-1 and attach it to a container of pure dry nitrogen (8). 1. Remove the protective covers and charging valve caps from the suspensions. 2. Turn "T" handles (1, Figure 4-1) of adapters (2) completely counterclockwise.
All Hydrair II suspensions are charged with compressed nitrogen gas with sufficient pressure to cause injury and/or damage if improperly handled. Follow all safety instructions, cautions, and warnings provided in the following procedures to prevent any accidents during oiling and charging. Proper charging of Hydrair II suspensions requires that three basic conditions be established in the following order: 1. Oil level must be correct. 2. Suspension piston rod extension for nitrogen charging must be correct. 3. Nitrogen charge pressure must be correct. For best results, Hydrair II suspensions should be charged in pairs (fronts together and rears together). If rear suspensions are to be charged, the front suspensions should be charged first. NOTE: For longer life of suspension components, a friction modifier should be added to the suspension oil. See the Specifications Charts at the end of this section. NOTE: Setup dimensions in the Specifications Charts must be maintained during oiling and charging procedures. However, after the truck has been operated, these dimensions may vary.
FIGURE 4-1. HYDRAIR CHARGING KIT NOTE: The arrangement of parts may vary from the illustration depending on the kit part number. 1. “T” Handle Valve 2. Charging Valve Adapter 3. Manifold Outlet Valves (from gauge) 4. Inlet Valve (from regulator) 5. Regulator Valve (Nitrogen Pressure) 6. Manifold 7. Charging Pressure Gauge (Suspensions) 8. Dry Nitrogen Gas Container
3. Ensure outlet valves (3) and inlet valve (4) are closed (turned completely clockwise).
Support Blocks For Oiling And Charging Dimensions
4. Turn swivel nut (small hex) on the charging valve three full turns counterclockwise to unseat the valve.
Before starting the oiling and charging procedures, supports should be fabricated to maintain the correct exposed piston rod extensions.
5. Attach charging valve adapters (2) to each suspension charging valve stem. 6. Turn "T" handles (1) clockwise. This will depress core of charging valve and open the gas chamber of the suspension. 7. Open both outlet valves (3). NOTE: By selective opening and closing of outlet valves (3), and inlet valve (4), suspensions may be charged separately or together. Removal of Charging Kit 1. Close both outlet valves (3). 2. Turn "T" handles (1) counterclockwise to release the charging valve cores. 3. Remove charging valve adapters (2) from the charging valves. 4. Tighten the swivel nut (small hex) on the charging valve. If a new charging valve is being used, tighten the swivel nut to 15 N•m (11 ft. lbs.), then loosen and retighten the swivel nut to 15 N•m (11 ft. lbs.). Loosen the swivel nut again and retighten to 6 N•m (50 in. lbs.). Install the valve cap finger-tight. 5. Install the charging valve caps and protective covers on both suspensions.
Nitrogen charging support blocks for the rear suspension are no longer necessary. However, oiling blocks are necessary to properly set the oiling height. Exposed piston rod extensions are specified for both oil level and nitrogen charging for Hydrair II suspensions. These dimensions are listed in the tables below Figures 4-2 and 4-5. Measure the dimensions from the face of the cylinder gland to the machined surface on the spindle at the front suspension. At the rear suspension, measure from the face of the cylinder gland to the piston flange. Support blocks may be made in various forms. Mild steel materials are recommended. Square stock or pipe segments at least 25 mm (1 in.) may be used. Blocks must be capable of supporting the weight of the truck during oiling and charging procedures while avoiding contact with plated surfaces and seals on the suspension. Refer to Figure 4-2 for front suspension support block placement and Figure 4-4 for rear support block placement.
FRONT SUSPENSION
All Hydrair II suspensions are charged with compressed nitrogen gas with sufficient pressure to cause injury and/or damage if improperly handled. Follow all the safety notes, cautions and warnings in these procedures to prevent accidents during servicing and charging. 1. Park the unloaded truck on a hard, level surface. Apply the parking brake and chock the wheels. 2. Thoroughly clean the area around the charging valve on the suspensions. Remove the protective covers from the charging valves.
2. Remove the charging valve cap. Turn the charging valve swivel nut (small hex) counterclockwise three full turns to unseat the valve seal. DO NOT turn the large hex. The charging valve body has a bleeder groove in its mounting threads, but for safety of all personnel, the valve body must not be loosened until all nitrogen pressure has been released from the suspension. 3. Depress the charging valve core to release nitrogen pressure from the suspension. When all nitrogen has been released, the suspension should have collapsed slowly and be seated solidly on the support blocks. Remove the top fill plug next to the charging valve (Figure 4-2).
Front Suspension Oiling
When blocks are in place on a suspension, they must be secured with a strap or other means to avoid accidental discharge. An unsecured block could fly loose as weight is applied, presenting the possibility of serious injury to nearby personnel and/or damage to the equipment. Overhead clearance may be reduced rapidly and suddenly when nitrogen pressure is released.
Make certain all personnel are clear and support blocks are secure before relieving nitrogen pressure from the suspension. Wear a face mask or goggles while relieving nitrogen pressure. NOTE: For longer life of suspension components, a friction modifier should be added to the suspension oil. See the Specifications Charts at the end of this section. 1. Position and secure oiling height dimension blocks in place (Figure 4-2). The blocks should be positioned 180 degrees apart to provide stability. When nitrogen pressure is released, the suspensions will lower and rest on the blocks. Ensure that the blocks do not mar or scratch the plated surfaces of the pistons or damage wiper seals in the lower bearing retainer. Support blocks must seat on the spindle and the cylinder housing.

4. Fill the suspension with clean Hydrair oil (with 6% friction modifier) until the cylinder is full to the top of the fill plug bore. Use drip pans and clean all spillage from the outside of the suspension. Allow the suspension to settle for at least 15 minutes to clear any trapped nitrogen and bubbles from the oil. Add more suspension oil if necessary. Install a new O-ring on the fill plug and install the plug. Front Suspension Nitrogen Charging
Lifting equipment (crane or hydraulic jacks) must be of sufficient capacity to lift the truck weight. Be certain that all personnel are clear of the lift area before the lift is started. Clearances under the truck may be suddenly reduced. 1. If removed, install the charging valve with new O-ring (9, Figure 4-3). Lubricate the O-ring with clean Hydrair oil. 2. Tighten valve body (6) (large hex) to 23 N•m (17 ft. lbs.). Swivel nut (4) (small hex) must be unseated by turning it counterclockwise three full turns.
Dry nitrogen is the only gas approved for use in Hydrair II suspensions. Charging of these components with oxygen or other gases may result in an explosion which could cause fatalities, serious injuries and/or major property damage. Use only nitrogen gas meeting the specifications shown in the Specifications Chart at the end of this section. 3. Install the Hydrair charging kit and a bottle of pure dry nitrogen. Refer to Installation of Charging Kit in this section. 4. Charge the suspensions with nitrogen gas to 50.8 mm (2 in.) greater than the charging height listed in Figure 4-2. Close inlet valve (4, Figure 4-1). 5. Remove the oiling blocks from the suspensions and install the nitrogen charging blocks. Secure the blocks to prevent accidental dislodging. NOTE: Use caution to prevent damage to plated cylinder surfaces and oil seals when installing the blocks. 6. Remove the center hose from manifold (6). 7. Open inlet valve (4) until the pressure drops below the pressure listed in Figure 4-2, then close the valve. 8. Install the center hose to manifold (6). 9. Charge the suspensions to the pressure listed in Figure 4-2. DO NOT use an overcharge of nitrogen to lift the suspensions off the charging blocks. 10. Close inlet valve (4, Figure 4-1). Leave outlet valves (3) open for five minutes to allow the pressures in the suspensions to equalize. 11. Close outlet valves (3). Remove the charging kit components. Refer to Removal of Charging Kit in this section. 12. If the charging valve is being reused, tighten swivel nut (4, Figure 4-3) to 6 N•m (50 in. lbs.).

13. If a new charging valve is being used, tighten the swivel nut to 15 N•m (11 ft. lbs.), then loosen and retighten the swivel nut to 15 N•m (11 ft. lbs.). Loosen the swivel nut again and retighten to 6 N•m (50 in. lbs.). Install the valve cap finger-tight. 14. Install the protective guard over the charging valve.
15. Raise the truck body in order to extend the front suspensions, allowing for removal of the nitrogen charging blocks. Ensure that sufficient overhead clearance exists before raising the body. If the suspensions do not extend after raising the body, turn the steering wheel from stop to stop several times. If the suspensions still do not extend enough to allow for removal of the blocks, use a crane or floor jacks to raise the truck and remove the blocks.
NOTE: For longer life of suspension components, a friction modifier should be added to the suspension oil. See the Specifications Charts at the end of this section. 1. Position and secure the oiling blocks in place so the blocks are seated between the frame and the rear axle housing (Figure 4-4). A block should be used on both the left and right sides of the truck.
The front Hydrair suspensions are now ready for operation. Visually check piston extension with the truck both empty and loaded. Record the extension dimensions. Maximum downward travel is indicated by the dirt ring at the base of the piston. Operator comments on steering response and suspension rebound should also be noted.
REAR SUSPENSION 1. Park the unloaded truck on a hard, level surface. Apply the parking brake, and chock the wheels. 2. Thoroughly clean the area around the charging valve on the suspensions. Remove the protective covers from the charging valves and the rubber covers from the suspension piston. Rear Suspension Oiling FIGURE 4-4. OILING BLOCK INSTALLATION
When blocks are in place on a suspension, they must be secured with a strap or other means to avoid accidental discharge. An unsecured block could fly loose as weight is applied, presenting the possibility of serious injury to nearby personnel and/or damage to the equipment. Overhead clearance may be reduced rapidly and suddenly when nitrogen pressure is released.
Make certain all personnel are clear and support blocks are secure before relieving nitrogen pressure from the suspension. Wear a face mask or goggles while relieving nitrogen pressure.

3. Rear Axle Housing
2. Remove charging valve cap. Turn the charging valve swivel nut (small hex) counterclockwise three full turns to unseat the valve seal. DO NOT turn the large hex. The charging valve body has a bleeder groove in its mounting threads, but for safety of all personnel, the valve body must not be loosened until all nitrogen pressure has been released from the suspension.
3. Depress the charging valve core to release nitrogen pressure from the suspension. When all nitrogen pressure has been released, loosen and remove the fill plug. The suspension should have collapsed slowly as gas pressure was released. The weight of the truck is now supported by the support blocks. NOTE: A plastic tube can be used to help bleed off trapped air inside the piston. 4. Remove the vent plug, pressure sensor, and charging valve (Figure 4-5). Use one of the open ports to fill the suspension with clean Hydrair oil (with 6% friction modifier). Fill until clean oil seaps from the open ports. Use drip pans and clean all spillage from the outside of the suspension. Allow the suspension to settle for at least 15 minutes to clear any trapped nitrogen and bubbles from the oil. Add more suspension oil if necessary. 5. Install the vent plug and pressure sensor onto the suspension. 6. Install a new O-ring onto the charging valve. Lubricate the O-ring with clean Hydrair oil. 7. Install the charging valve onto the suspension. Tighten valve body (6, Figure 4-3) to 23 N•m (17 ft. lbs.).

Rear Suspension Nitrogen Charging
Lifting equipment (overhead or mobile cranes, or hydraulic jacks) must be of sufficient capacity to lift the truck weight. Ensure that all personnel are clear of lift area before lifting is started. Clearances under the truck may be suddenly reduced.
Ensure that the automatic apply circuit has not applied the service brakes during truck maintenance. If the front brakes are applied during rear suspension charging, the axle cannot pivot for frame raising/lowering, and the rear suspension may be unable to move up or down. 1. If removed, install charging valve with new Oring (9, Figure 4-3). Lubricate the O-ring with clean Hydrair oil. 2. Tighten valve body (6) (large hex) to 23 N•m (17 ft. lbs.). Swivel nut (4) (small hex) must be unseated by turning it counterclockwise three full turns.
Dry nitrogen is the only gas approved for use in Hydrair II suspensions. Charging of these components with oxygen or other gases may result in an explosion which could cause fatalities, serious injuries and/or major property damage. Use only nitrogen gas meeting the specifications shown in the Specifications Chart at the end of this section. 3. Install Hydrair charging kit and a bottle of pure dry nitrogen. Refer to Installation of Charging Kit in this section. 4. Charge the suspensions with nitrogen gas to 38 mm (1.5 in.) greater than the charging height listed in Figure 4-5. 5. Slowly release gas until the suspensions match the charging height listed in Figure 4-5. 6. Close inlet valve (4, Figure 4-1). Leave outlet valves (3) open for five minutes to allow the pressures in the suspensions to equalize.
7. Ensure that both of the suspension cylinders are extended the same distance ± 10 mm (0.39 in.). If the difference in the extension from side to side exceeds this amount, check the front suspensions for equal extension. Adjust the front suspensions as necessary. NOTE: A low left front suspension will cause the right rear suspension to be high. A low right front suspension will cause the left rear suspension to be high. 8. Close outlet valves (3). Remove the charging kit components. Refer to Removal of Charging Kit in this section. 9. If the charging valve is being reused, tighten swivel nut (4, Figure 4-3) to 6 N•m (50 in. lbs.). 10. If a new charging valve is being used, tighten the swivel nut to 15 N•m (11 ft. lbs.), then loosen and retighten the swivel nut to 15 N•m (11 ft. lbs.). Loosen the swivel nut again and retighten to 6 N•m (50 in. lbs.). Install the valve cap finger-tight. 11. Install the protective guards over the charging valves. Install the rubber covers over the piston rods. The rear Hydrair suspensions are now ready for operation. Visually check piston extension with the truck both empty and loaded. Record the extension dimensions. Maximum downward travel is indicated by the dirt ring at the base of the piston. Operator comments on steering response and suspension rebound should also be noted.

AUTOMATIC LUBRICATION SYSTEM CHECKOUT PROCEDURE GREASE REQUIREMENTS Grease requirements will depend on ambient temperatures encountered during truck operation: •
Above 32°C (90°F) - Use multipurpose grease (MPG).
NLGI
No.2
•
-32° to 32°C (-25° to 90°F) - Use NLGI No. 1 multipurpose grease (MPG).
•
Below -32°C (-25°F) - Refer to local supplier for extreme cold weather lubricant requirements.
PUMP HOUSING OIL The pump housing must be filled to the proper level with SAE 10W-30 motor oil. Check the oil level every 1000 hours. To add oil, remove oil level plug (4, Figure 3-2) and fill the housing to the bottom of the plug hole.
SYSTEM PRIMING The system must be full of grease and free of air pockets to function properly. After maintenance, if the primary or secondary lubrication lines were replaced, it will be necessary to prime the system to eject all entrapped air. 1. Fill lube reservoir with lubricant, if necessary. 2. To purge air from the main supply line, remove the main supply line at the canister and connect an external grease supply to the line. 3. Remove plugs from each injector group in sequence (right front, left front, and rear axle). 4. Using the external grease source, pump grease until grease appears at the group of injectors and re-install the pipe plug. Repeat for remaining injector groups. 5. Remove the caps from each injector and connect an external grease supply to the zerk on the injector and pump until grease appears at the far end of the individual grease hose or the joint being greased.

PRESSURE AND FLOW CONTROL High pressure hydraulic fluid from the truck steering system is reduced to 2 240 to 2 413 kPa (325 to 350 psi) by pressure reducing valve (4, Figure 3-1) located on the manifold on top of the pump motor. This pressure can be observed on the gauge installed on the manifold. Occasionally check to verify that pressure is within the above limits. The pressure reducing valve is factory adjusted. DO NOT tamper with this setting. Flow control valve (5) controls oil flow through the pump. The valve is factory adjusted to 2.5 gpm (9.5 L/min.). DO NOT tamper with this setting.
SYSTEM CHECKOUT To check system operation (not including timer), proceed as follows: 1. Turn key switch ON and start the engine. 2. Actuate the lube system test switch at the reservoir/pump assembly on the front bumper. 3. The motor and pump should operate until the system attains 2500 psi (17 237 kPa). 4. Once the required pressure is reached, the pump motor should turn off and the system should vent. 5. Check for pump, hose or injector damage or leakage with the system pressurized. FIGURE 3-2. PUMP CONTROLS 3. Pressure Gauge 1. Pressure Reducing 4. Oil Level Plug Valve 2. Manual Override Switch 5. Flow Control Valve (Test)
6. After checking the system, shut off the engine. Repair the lube system as necessary.
PREVENTATIVE MAINTENANCE PROCEDURES The following maintenance procedures should be used to insure proper system operation. Daily Lubrication System Inspection 1. Check grease reservoir level. Inspect grease level height after each shift of operation. Grease usage should be consistent from day-today operations. •
Lack of lubricant usage would indicate an inoperative system. Excessive usage would indicate a broken supply line. 2. Check filter bypass indicator when filling reservoir. Replace element if bypassing. 3. Check all grease feed line hoses from the SL-1 Injectors to the lubrication points. a. Repair or replace all damaged feed line hoses. b. Make sure that all air is purged and all new feed line hoses are filled with grease before sending the truck back into service. 4. Inspect key lubrication points for a bead of lubricant around seal. If a lubrication point appears dry, troubleshoot and repair problem.
250 Hour Inspection 1. Check all grease feed line hoses from the SL-1 Injectors to the lubrication points (see, Figure 31). a. Repair or replace all worn / broken feed line hoses. b. Make sure that all air is purged and all new feed line hoses are filled with grease before sending the truck back into service. 2. Check all grease supply line hoses from the pump to the SL-1 injectors. a. Repair or replace all worn / broken supply lines. b. Make sure that all air is purged and all new supply line hoses are filled with grease before sending the truck back into service. 3. Check grease reservoir level.
c. Check that all filler plugs, covers and breather vents on the reservoir are intact and free of contaminants. 4. Inspect all bearing points for a bead of lubricant around the bearing seal. It is good practice to manually lube each bearing point at the grease fitting provided on each Injector. This will indicate if there are any frozen or plugged bearings, and will help flush the bearings of contaminants. 5. System Checkout a. Remove all SL-1 injector cover caps to allow visual inspection of the injector cycle indicator pins during system operation. b. Start truck engine. c. Actuate the manual override switch (6, Figure 3-1). The hydraulic motor and grease pump should operate. d. With the grease under pressure, check each SL-1 injector assembly. The cycle indicator pin should be retracted inside the injector body. e. When the system attains 17,237 kPa (2500 psi), the pump should shut off and the pressure in the system should drop to zero, venting back to the grease reservoir. f. With the system vented, check all of the SL-1 injector indicator pins; all of the pins should be visible. Replace or repair injectors, if defective. g. Reinstall all injector cover caps. h. Check timer operation. NOTE: With engine running, lube system should activate within 5 minutes. The system should build 13,790 to17,237 kPa (2000 to 2500 psi) within 25-40 seconds. i. If the system is working properly, the truck is ready for operation. j. If the system is malfunctioning, refer to the troubleshooting chart.
a. Fill reservoir if low. b. Check reservoir for contaminants. Clean, if required.
1000 Hour Inspection 1. Check pump housing oil level and correct if necessary.

Vehicle Speed - observe reported speed while testing the speedometer with the GE DID panel. Set to 20 mph and observe 20mph on speedometer as well as within VHMS. 4. Battery 12V A - check with batteries fully charged or being charged. Voltage should be about 12 volts. 5. Battery 12V B - check with batteries fully charged or being charged. Voltage should be about 12 volts. 6. Battery 12V C - check with batteries fully charged or being charged. Voltage should be about 12 volts.
CHECK OUTPUTS FROM THE INTERFACE MODULE For 830E only: 1. Check the High Hydraulic Temperature Lamp by pressing the lamp test rocker switch. The lamp should light.
For 930E and 960E: 1. Check the output of Brake Cooling RPM Advance 1, Brake Cooling RPM Advance 2, Brake Oil Temperature Gauge (930E only), and High Brake Oil Temp Lamp by placing a 169 ohm resistor (a range of 1520 to 1860 should work) in place of any of the four input temperature probes.

Brake Cooling RPM Advance 1 should go to 24 volts (check at TB40-B). Brake Cooling RPM Advance 2 should go to 24 volts (check at TB40-C). The Brake Oil Temperature Gauge (930E only) should read near the middle of the red band. The High Brake Oil Temp light should come on. If the output functions do not turn on, read the value of the temperature for the selected input in VHMS Watcher. It should be between 126 and 140 C. If the temperature reading is low check wiring for high resistance between the probe and Interface Module. If the temperature reading is high check for shorts in the wiring. It the temperature is in the right range but the output functions do not work, check the Interface Module output circuit and wiring associated with any non-working function.
For 960E only: Actuate and hold the lamp test switch in the operator's cab. The following lamps are driven by the Interface Module and should come on (along with all the other lamps): 1. Park Brake Lamp 2. Low Fuel Lamp 3. Batt Charge Alt Failure Lamp 4. 1MWarning Lamp 5. High Brake Oil Temp Lamp
The functionality of the Fuel Level output can be confirmed by observing the needle position of the gauge when the low fuel lamp comes on. 1.
2. 3.
Dismount the sending unit only from the tank and position the gauge to a low level with a screwdriver. The shaft of the screwdriver will turn this magnetically coupled sending unit to any position you desire. Set the gauge to empty. After 15 seconds, the Low Fuel Light should come on. Return the gauge to the approximate position of the actual fuel in the tank before remounting it.
The Park Brake Solenoid and Brake Apply output can be checked with the following procedure. 1. Turn parking brake off. Park brake valve should be energized and brake auto apply valve should not. Energization of these valves can be determined by checking voltage across the valves or check for magnetism in the valve with a screwdriver. 2. Use the GE DID panel to set the truck speed to some elevated value such as is used to calibrate the speedometer. The park brake valve should continue to be energized. The auto apply valve should continue to be off. 3. With the truck speed signal still high, turn the park brake on. The park brake valve should m continue to be energized, and the auto apply valve should stay off.

STANDARD TORQUE CHARTS AND CONVERSION TABLES This manual provides dual dimensioning for most specifications. U.S. standard units are specified first, with metric (SI) units in parentheses. References throughout the manual to standard torques or other standard values will be to one of the following charts or tables. For values not shown in these charts or tables, standard conversion factors for most commonly used measurements are provided in TABLE XIII, page A5-6. Standard torque values are not to be used when “turnof-the-nut” tightening procedures are recommended. INDEX OF TABLES TABLE I . . . . . . . Standard Torque Chart (SAE) TABLE II .

The Komatsu engineering department does not recommend the use of special friction-reducing lubricants, such as Copper Coat, Never-Seez®, and other similar products, on the threads of standard fasteners where standard torque values are applied. The use of special friction-reducing lubricants will significantly alter the clamping force being applied to fasteners during the tightening process. If special friction-reducing lubricants are used with the standard torque values listed below in Table I, excessive stress and possible breakage of the fasteners may result. Where the torque tables specify “Lubricated Threads” for the standard torque values listed, these standard torque values are to be used with simple lithium base chassis grease (multi-purpose EP NLGI) or a rustpreventive grease (see list, page A5-2) on the threads and seats unless specified otherwise. NOTE: Ensure the threads of fasteners and tapped holes are free of burrs and other imperfections before assembling.

STANDARD ASSEMBLY TORQUES For 12-Point, Grade 9 Cap Screws (SAE)
STANDARD ASSEMBLY TORQUES For Class 10.9 Cap screws & Class 10 Nuts
The following specifications apply to required assembly torques for all 12-point, grade 9 (170,000 psi minimum tensile) cap screws.
The following specifications apply to required assembly torques for all metric Class 10.9 finished hexagon head cap screws and Class 10 nuts.
• Cap screw threads and seats shall be lubricated when assembled.
• Cap screw threads and seats shall not be lubricated when assembled. These specifications are based on all cap screws, nuts, and hardened washers being phosphate and oil coated.
NOTE: Unless the instructions specifically recommend otherwise, these standard torque values are to be used with simple lithium base chassis grease (multi-purpose EP NLGI) or a rust preventive grease (see list, this page) on the threads. • Torques are calculated to give a clamping force of approximately 75% of proof load. • The maximum torque tolerance shall be ±10% of the torque value shown. TABLE II. STANDARD ASSEMBLY TORQUE for 12-Point, Grade 9 Cap screws
NOTE: If zinc-plated hardware is used, each piece must be lubricated with simple lithium base chassis grease (multi-purpose EP NLGI) or a rust preventive grease (see list, this page) to achieve the same clamping forces provided below. • Torques are calculated to give a clamping force of approximately 75% of proof load. • The maximum torque tolerance shall be within ±10% of the torque value shown.
