1. ESTR ESTRUC UCTU TURA RA DE LA BOMBA BOMBA Los movimientos de los pistones de la bomba hacen que el aceite hidráulico se desplace desde el lado de aspiración hacia el de presión (descarga). La bomba es una bomba de pistones axiales en donde los pistones se desplazan en la dirección del eje de accionamiento. La bomba de caudal variable utilizada por Tamrock es una bomba del tipo de plato motriz. Los extremos de los pistones deslizan contra la placa motriz, cuyo ángulo depende de la señal LS (presión). Las lumbreras de la bomba están están marcadas marcadas de la siguiente siguiente manera: manera: S=lumb S=lumbrera reras s de aspira aspiració ción n B=lumb B=lumbrera reras s de impuls impulsión ión (o de descar descarga) ga) L=lumbrera L=lumbrera de drenaje drenaje X=lumbrera X=lumbrera de pilotaje pilotaje Regulador de Presión

BOMBA DE CAUDAL VARIABLE La unidad de control montada sobre la bomba controla el ángulo del plato de regulación. La bomba tiene separados los reguladores de presión y de caudal. La presión del sistema entra en la unidad de regulación a través del conducto B1. Dirigiéndosedicha presión hacia el extremo izquierdo de los husillos de control a través de los orificios practicados en dichos husillos de regulación. El conducto A lleva la presión hasta pistón de regulación que regula la inclinación del plato de regulación. El conducto T conduce a la carcasa de la bomba, que está connectado al depósito a través del conducto de drenaje.

3.1. REGULADOR DE PRESIÓN Cuando se incrementa la presión dentro del conducto B1, el husillo P de la unidad de regulación se desplaza hacia la derecha, contra el muelle. Cuando se alcanza la máxima presión de tarado, se abre la conexión entre B1 y A, fluyendo aceite hacia el pistón de regulación de inclinación, que reduce la inclinación del plato de regulación. El tornillo de regulación C se utiliza para regular la presión máxima del sistema. Esta presión debe tener un valor de alrededor de 20 bar menos que la presión apertura de la válvula principal de alivio de presión (=válvula de seguridad).

3.2. REGULADOR DE CAUDAL Los caudales varían de acuerdo con la demanda del sistema. La presión del sistema afecta a través de B1 al extremo izquierdo del husillo F. La presión del conducto sensor de carga X afecta al extremo de la derecha, donde se encuentra situado el muelle. La diferencia de presión sobre la válvula direccional V del sistema, fuerza al husillo F del regulador contra el muelle. Si la diferencia de presión aumenta, se abre la conexión entre los conductos B1 y A, y la bomba se regula para un caudal menor. Si la diferencia de presión se reduce, se abre la conexión entre los conductos A y T, y aumenta el caudal de la bomba.

3.2.1. CONDUCTOS SENSORES DE CARGA Se pueden regular varios sistemas (X1, X2, etc.) al mismo tiempo, regulando las presiones LS de cada sistema.

3.2.2. PRESIÓN DE ESPERA En la situación, en la que no se encuentra ningún dispositivo en funcionamiento, el conducto sensor de carga X se encuentra sin presión, porque está conectado al conducto de retorno al depósito a través de la válvula direccional. La presión del sistema desde B1 fuerza al husillo del regulador de caudal F hacia la derecha contra el muelle. La conexión entre B1 y A se abre totalmente, y la bomba se ajusta a caudal cero y a baja presión. La presión de espera del sistema se ajusta con el tornillo D. El valor deseado se ajustará de acuerdo con las instrucciones de la bomba (dependiendo del sistema). E

4.3. Variable displacement pump Pump operation The variable displacement pump is an axial – piston pump, where the pistons move parallel to the axle. The reciprocating motion of the pistons transfers the oil from the intake side to the pressure side. The capacity of the variable displacement pump can be steplessly adjusted, although the pump rotates at the standard rotation speed. The adjustment is performed by changing the stroke length of the pistons. The stroke length can be adjusted by changing the swash plate angle.

Stroke length

Highest swash plate angle = highest output

Stroke length

Stroke length

Smaller swash plate angle = partial output

Swash plate angle = Output = 0

Pump structure

The variable displacement pump used by Tamrock is of the swash plate type, in which the pistons slide along the slide plate with their slide shoes. The swash plate spring maintains the plate at the maximum angle (with full pump output), unless the controller decreases the angle (output). The pump takes in oil from hole S and produces the required operating pressure to hole B.  

HYDRAULIC POWERPACK HPP 545, 555 Maintenance and repair The swash plate angle (= pump output) is controlled with the controller in the pump. The pump has a separate adjustment for pressure and volume flow. The system pressure acts in the controller line B1. The pressure is led to the left end of the adjustment spools through bores in the controller spools. Line A leads to the control piston, which adjusts the pump angle. Line T leads to the pump housing, and is connected to the receiver via the drain oil line. Maximum pressure controller When the pressure rises in line B1, controller spool P is pushed to the right against the spring. When the adjusted maximum pressure has been reached, the connection from line B1 to line A opens and the oil flows to the control piston, which adjusts the pump angle, and the pump is adjusted to a lower angle (= lower output). The maximum system pressure is adjusted by turning screw C. The pressure must be approximately 20 bar lower than the opening pressure of the main pressure – relief valve (= safety valve). The pressure is increased by turning the screw clockwise. Volume flow controller The volume flow produced by the pump changes according to the needs of the actuators. The pressure after the proportional directional valve in the system affects the spring of controller spool F via load – sensing line X. Correspondingly, the pressure in the pump pressure line pushes the spool against the spring. If the actuator pressure drops in point C, the pressure in the load – sensing line also drops. The pump pressure moves the spool to position 1. Then a connection from line B1 to line A opens, and the pump is adjusted to a lower output. If the actuator pressure rises in point C, the pressure in the load – sensing line moves the spool to position 2. Then a connection from line A to line T opens, and the pump is adjusted to a higher output. Load –sensing lines The pressure required by various actuators is led to the pump controller via several load – sensing lines X1, X2, ..., which enables the pump to compensate for all pressure changes caused by the load. Then each actuator always moves at the speed which is selected for it with the proportional directional valve. Idle –running pressure (Stand by) A situation where no actuators are on. In that case, load – sensing line X is pressureless because it is connected to the receiver line via the directional valve. System pressure B1 pushes volume flow controller spool F to the right against the spring. The connection from line B1 to line A opens, and the pump is adjusted to zero output and low pressure (30 bar). The idle – running pressure (30 bar) of the system is adjusted with screw D. The pressure is increased by turning the screw clockwise.

MONITORING AND SAFETY DEVICES

The following controls prevent the drilling or stop the hydraulic power pack and turn on the corresponding indicator: Phase sequence control  If the phase sequence is incorrect, the indicator light turns on and the motors are prevented from starting. Water pressure control  If the water pressure remains under 2.8 bar for over 4 seconds, the pressure monitoring system of the equipment will stop the drilling. Air pressure control  If the shank lubrication pressure remains under 2.8 bar for over 10 seconds, the pressure monitoring system of the equipment will stop the drilling. Hydraulic oil level control  If the oil level in the hydraulic oil receiver drops below the allowed minimum, the power pack stops after 3 seconds.  Hydraulic oil temperature The power pack stops if the oil temperature rises above 75 C. Compressed air too hot  If the cooler does not cool the compressed air enough, this control stops the electric motor. (Australia: the indicator light indicates an alarm from the thermistor protector, which monitors the temperature of the compressor.) Overload of the electric motor of the hydraulic power pack  If the coil temperature rises above 155C or the motor circuit breaker is triggered, the power pack will stop. Compressor, water pump, or high –pressure water pump (optional) overload  The next controls will turn on the indicator:  Oil return filter and pressure filter control The indicator will be turned on in the following cases: – The filter has become so dirty that it must be replaced. – The return filter of the power pack is clogged. – The pressure filter of the power pack is clogged.

Start –up  

7.3.

Make sure that starting will not cause any danger and that there is nobody in the danger areas. Ensure that the parking brake of the carrier is engaged (ON position). Check that no service is being performed and that the doors of the main distribution room are properly closed. In case the machine is equipped with a fault current and overcurrent protection centre, check its operation by pressing the TEST-button. Unless the power is cut off, an electrician must be called to repair the equipment. Turn the main switch to the ON-position and switch on the working lights. Clean the water hose by letting the water run from the hose for a moment. Then connect the hose. (The air hose must be cleaned using the same principle before connecting.) Turn the compressor and water pump switches to position A (if necessary). Check the hydraulic oil level in the receiver. Check that the drilling control levers are in the middle position and that the emergency stop button is up.

Start the power pack by pressing the START button. If you start drilling at a new site, make sure that the voltage is adequate.

Stopping Never stop the rig when a function (movement) is in progress, as it may cause damage to the variable displacement pump.

PUMPS

The hydraulic system includes two pumps as standard. -- variable displacement pump -- constant--output pump The variable displacement pump delivers oil to the percussion-, feed- and boom hydraulics circuits. The pump is constantly adjusting itself to maintain an output--line pressure that is higher than the load--sensing line pressure, by a pressure difference defined for the pump. The pump receives load data from the load--sensing line. The pump is adjusted so that its maximum output is achieved when drilling with full power. The pressure difference as well as the pump’s maximum output pressure can be adjusted using the pump controls. The constant--output pump delivers oil to the rotation circuit and, thus, also functions as a feed pump for the system.

6.

OIL FILTERING OF THE HYDRAULIC SYSTEM

The system contains pressure and return flow filtering. Pressure filtering is only used in the variable displacement pump (1) line, but return--flow filtering is common for both pumps (1 and 2). The hose--connection filter (5), with a filtering capacity of 20 m m abs., is used in pressure filtering. If the pressure difference in the filter rises to over 2.5 bar, the indicator lamp H611 in the indicator panel lights to indicate that the filter element needs to be changed. The filter--element frame has a by--pass filter, that opens if the pressure rises above 3.5 bar. The return flow of both pumps goes through the filter (45). The return filter is a hose--connection type. The filtering capacity of the return filter is 10 mm abs. If the pressure difference in the filter rises to over 2.0 bar, the indicator lamp H607 in the indicator panel lights to indicate that the filter element needs to be changed. The filter--element frame has a by--pass filter, that opens if the pressure rises above 2.4 bar. The purity classification recommended by the manufacturer for this system follows the 17/13 ISO standard. If the oil is cold (under +30 C), the pressure and return flow control will be by --passed, so that false alarms due to the higher viscosity of the cold oil will be ignored. ˚

CAUTION

7.

AIR FILTERING OF THE HYDRAULIC OIL TANK

The hydraulic oil tank also has an air filter with a filtering capacity of 5 mm. This filter has no control, but in order to ensure the purity of the oil, it should be changed at intervals defined in the service instruction.

8.

COOLING OF THE HYDRAULIC--SYSTEM OIL

The return oil of different devices flows through the cooler (42) and the return--oil filter (45) into the hydraulic oil tank (49). The oil cooler uses water as coolant. Oil cooling is always turned on when the water flushing is on. The hydraulic system is equipped with thermostatic valve. When the temperature of the hydraulic oil rises, thermostatic valve let the coolant water flow through the oil cooler to the ground. The hydraulic system is also equipped with a hydraulic--oil temperature control. The temperature of the oil in the tank is monitored using a sensor (50). This temperature sensor stops the power pack, if the temperature rises above +75 C. At the same time, the indicator lamp H610 in the indicator panel lights. ˚

DRILLING OPERATION

9.1.Drilling position Always, when beginning drilling, the drilling--bolting selector lever S85 must be in the drilling position. Drilling in the manual position: -- Push the selector lever S85 to the 12 o’clock position. -- The flushing--control lever S74 is pushed forward to the 12 o’clock position (water flushing). -- Feed forward and rotation counterclockwise are selected by pushing the joystick S73 to the 1 o’clock position. -- Pull the control lever S75 to the 6 o’clock position to begin drilling with 1 / 2-- power. -- When the drill bit has penetrated about 10 to 15 cm, push the percussion--control lever S75 to the 12 o’clock position to start drilling with full power. Air flushing must not be turned on in situations where the drill rod is moved back and forth (”pumped”) in the hole. WARNING

9.2.The effect of the potentiometer The drilling--power potentiometer R70 is used for adjusting the drilling power. By adjusting the R70, you can affect the feed pressure--proportional valve (10) positions through the main valve unit. The feeding--force potentiometer is kept in position 1 to 10 depending on the hardness of the rock. Avoid using low feeding force. It may cause wear in the drilling--rod threads and in the shank.

10.2.Drilling ½ --power Percussion

The spool of the percussion main valve (6) will move into position 1 when the coil Y1 is activated and the percussion comes on. The oil from the percussion pump (1) will flow through the check valve (43) and the pressure filter (5) to the percussion main valve (6). From there the oil goes to the rock drill percussion mechanism (32) and back to the tank through the return line. At the same time the coil Y42 of the control valve (25) moves the spool into position 1 and opens the load--sensing line of the pump (1). The oil flows through the restrictor (24) and the control valve (25) to the shuttle valve (26). From there the oil pressure activates through the load--sensing line the flow control valve of the pump (1) to give the information of the present load level. If the percussion ½ --power is selected the coil Y120 of the drilling control main valve (27) will move the spool into position 2. In this case the percussion pressure is adjusted by the pressure relief valve (28) (percussion ½ --power pressure = 100 bar). Percussion pressure is shown in pressure gauge (39). Feed

The oil for the feed comes also from the pump (1). The spool of the feed directional valve (7) will move into position 2 when the coil Y3 is activated. Part of the oil from the pump (1) will flow through the directional valve (7), one--way restrictor (8) and the proportional feed pressure reducing valve (10) to the shuttle valve (46A) and trough the overcenter valve (47) to the feed mechanism (33). The oil will flow back to the tank by the return line through the overcenter valve (47), to the shuttle valve (46B) and the one--way restrictor (9) and the directional valve (7). Return oil can also, depending of the position of the ball in shuttle valve (46B), flow through one--way restrictor (22) and directional valve (20) to tank. The max. feed speed forwards is controlled by the one--way restrictor (8). Feed pressure is controlled by potentiometer R80 in control panel and the pressure is shown in pressure gauge (40). Rotation

The oil for rotation comes from rotation pump (2) (gear pump), which gives constant output. When rotation anticlockwise is selected, coil Y5 in rotation directional valve (12) is activated. Oil goes through directional valve to rotation mechanism and return oil goes to tank through return line. Rotation speed is controlled by proportional flow control valve (63), which allows part of constant oil flow go to tank and this reduces rotation speed of drifter. The max. pressure (150 bar) of the pump (2) and rotation is adjusted by the pressure relief valve (30) which is located in the pressure control block. Rotation pressure can be seen on pressure gauge (41).

10.3.Drilling full power Percussion

The spool of the percussion main valve (6) will move into position 1 when the coil Y1 is activated. and the percussion comes on. The oil from the percussion pump (1) will flow through the check valve (43) and the pressure filter (5) to the percussion main valve (6). From there the oil goes to the rock drill percussion mechanism (32) and back to the tank through the return line. At the same time the coil Y42 of the control valve (25) moves the spool into position 1 and opens the load--sensing line of the pump (1). The oil will flow through the restrictor (24) and the control valve (25) to the shuttle valve (26). From there the oil pressure activates through the load--sensing line the flow control valve of the pump (1) to give the information of the present load level. If the percussion full--power is selected the coil Y122 of the drilling control main valve (27) will move the spool into position 1. In this case the percussion pressure is adjusted by the pressure relief valve (29) (percussion full--power pressure = 150 bar). The pressure is shown in pressure gauge (39). Feed

The oil for the feed comes also from the pump (1). The spool of the feed directional valve (7) will move into position 2 when the coil Y3 is activated. Part of the oil from the pump (1) will flow through the directional valve (7), one--way restrictor (8) and the proportional feed pressure reducing valve (10) to the shuttle valve (46A) and trough the overcenter valve (47) to the feed mechanism (33). The oil will flow back to the tank by the return line through the overcenter valve (47), to the shuttle valve (46B) and the one--way restrictor (9) and the directional valve (7). Return oil can also, depending of the position of the ball in shuttle valve (46B), flow through one--way restrictor (22) and directional valve (20) to tank. The max. feed speed forwards is controlled by the one--way restrictor (8). Feed pressure is controlled by potentiometer R80 in control panel and the pressure is shown in pressure gauge (40).

10.4.Anti --jamming automatics The anti--jamming automatics operate in a situation where the drill--rod rotation becomes difficult due to, for example, a fissure in the rock. The selection switch S79 must be in the “on” position. Through the rotation pressure switch (14), the control system monitors the rotation--circuit pressure. When the drill bit hits a fissure, the rotation gets more difficult and the torque needed for rotation increases. The pressure in the rotation circuit starts to rise. If the pressure rises over the defined anti--jamming pressure (see table on Anti--jamming pressure control), and stays higher than this value longer than the defined anti--jamming detection time (factory setting: 0.8 s), the system initiates the anti--jamming automatics. Reel Y4 of the feed directional control valve (7) receives control and the spool moves to position 1, which means that the feed direction changes and the rock drill moves backward. When the rotation pressure lowers under the defined anti--jamming pressure, the drill functions are initiated, first with 1 / 2 power values and then after 4 seconds, move to full power.

10.5.Flushing--pressure malfunction If in a drilling situation (full--power percussion, rotation, feed and flushing turned on) the flushing--water pressure falls under the value defined for pressure switch S422, a flushing--malfunction operation is initiated. This means that feed is used for pulling the rock drill back. If the flushing pressure returns to normal, the machine will start drilling first with 1 / 2 power values, and then after 4 seconds, moves to full power.

The return oil will flow back to tank through the over center valve (47), shuttle valve (46B), one--way restrictor (22) and directional valve (20). Return oil can also, depending of the position of the ball in shuttle valve (46B), flow through one--way restrictor (9) and directional valve (7) to the tank. At the same time the coil Y42 of the control valve (25) moves the spool into position 1 and opens the load--sensing line of the pump (1). The oil will flow through the restrictor (24) and the control valve (25) to the shuttle valve (26). From there the oil pressure activates through the load--sensing line the flow control valve of the pump (1) to give the information of the present load level.

10.10.Boom Cabolt boom hydraulics are based on load sensing functions. In boom hydraulics there are one proportional flow control valve (Y139) and six on--off directional valves, one for every boom function. Proportional flow control valve (Y139) is located to drilling block, directional valves are located next to the drilling block. Working principle for this circuit is as follows: When joy--stick S77 e.g. is pulled gently backwards, electrical signal goes to PLC and it activates coil Y27 (boom lifting). At the same time signal goes also to proportional flow control valve Y139 and valve opens a little. Now oil from piston pump starts to flow to boom lifting cylinder. The boom pressure line B6 is connected to the pump (1) flow controller through the shutter valve Y179, connection LS1, shuttle valve (26), and connector LS. If joy--stick is pulled more backwards, proportional valve open’s more and more oil from pump goes top lifting cylinder. Pump pressure can be seen from percussion pressure gauge (39). Boom function is selected with joy--stick S77 movement direction and speed (oil flow) is adjusted by the joy--stick S77 movement.

10.11.Basket--boom movements (optional) During the basket--boom movements, reel Y139 of the proportional valve (31) receives control and moves the spool into position 1. From the pump (1), the oil flows to the boom’s proportional valve (31). The position of the boom’s proportional valve (31) spool depends on the position of the boom joystick, which also controls the oil flow into the boom movements (the movement speed). The boom pressure line B6 is connected to the pump (1) flow controller (47) through the shutter valve Y179, connection LS1, shuttle valve (26) and connector LS. The pump (1) pressure is determined by the boom--movement load, which causes the movements to remain at a constant velocity. The return oil flows through the proportional valve (31) to the tank.

The factory--adjusted anti--jamming automatics pressure (90 to 110 bar) can be readjusted with the anti--jamming automatics pressure switch (14). The value can be readjusted depending on the drilling conditions. The anti--jamming automatics delay times have fixed adjustment values in the logic program (PLC). If the pressure exceeds the adjusted value for more than 0.8 seconds, the feed will begin moving backward. When the pressure returns under the adjusted value, the feed will begin moving forward after 0.5 seconds, using ½ percussion and ½ feed pressures for the next 4 seconds, after which full percussion and feed pressures will become effective. -- Turn the anti--jamming automatics off (with selector switch S79). -- Use a suitable tool to prevent the drilling rod from rotating and engage rotation with joystick S73 by pulling it to the right. -- Adjust the rotation pressure--relief valve (30) temporarily to the required anti--jamming automatics pressure. Check the adjusted pressure from the pressure gauge (41). -- Use an ohm meter to adjust the anti--jamming automatics pressure switch (14) so that it functions with the required anti--jamming automatics pressure or check when the logic input Ch02.07 is activated. When the adjustment is carried out correctly the input led will come on and off during a single revolution of the pressure--switch adjusting screw. -- Adjust the rotation--pressure relief valve (30) back to its original value.

TROUBLESHOOTING

GENERAL

Before performing more detailed measurements, you should first perform the following general inspection procedures: -- hydraulic oil temperature (normally 40 -- 50 _C) and viscosity. -- hydraulic oil level. -- return and pressure filter indicator lamps and other possible alarm signals (e.g. water and air). -- External leaks of hoses, connections and other hydraulic components. -- The mechanical condition of components (e.g. slide piece and roller adjustments). -- Input voltage to the device. -- External cable damage. -- Mounting of electric plugs. -- Pressure gauge displays.

12.1.The pump does not operate with the required adjustments or does not operate at all. Pump does not rotate at all or rotates slowly -- Check whether the pump or other power--pack components emit abnormal sounds. -- Repair or change faulty components. -- Perform measurements to make sure that the electric motor has adequate input voltage. -- If it has, check the elctric motor, the clutch component, pump--drive shaft and pump. -- Repair or change abovementioned faulty components. -- If there is no voltage input to the electric motor, refer to electrical troubleshooting.

B (48)

Install the pressure gauge into the LS port of the drilling--control block. Start the power pack and let it idle. If the pressure in the drilling--control block port LS is between 0 to 6 bar (i.e. tank pressure), the fault is most likely in the adjustment of the pump regulator A (47) or the pump is clogged. Adjust the pump’s free--circulation pressure into its correct value using the regulator A (47) according to 13.2. If the above--mentioned procedures do not help, repair or clean the regulator A (47) or change the entire regulator unit. Adjust the pump’s free--circulation pressure into its correct value using the regulator A (47) according to 13.2. If there is over 6 bar of pressure in the drilling-- control block port LS when the pump is in free circulation, the valves (25) or (31) might be clogged or they are receiving control voltage. Prior to removing the electrical connection of the boom--hydraulics proportional valve (31), fuse 321.8 must be opened.

CAUTION

--

--

Remove the electrical plugs of the valves in question (25 and 31). If the fault remains, the cause is most likely clogged valves. Repair, clean or change the faulty valve. When the pump’s free--circulation pressure has been adjusted to the correct value, check the pump’s pressure--limit value (regulator B) by e.g. driving the zoom cylinder in. The pressure should be approximately 220 bar. Read the pressure from the gauge (39). If the pressure differs from the above--mentioned value, adjust the pressure correctly using the pump regulator B according to 13.2. If the regulator B does not react to the adjustment, the fault might be in the system’s main--pressure relief (23) or the pump regulator B. E

CABOLT 7 AND 8 Operation, testing and adjusting Clean or change the main pressure relief (23). If the adjustment still does not work, clean and repair regulator B or change the entire regulator unit. Perform the adjustment according to section 13.1.

12.2.Percussion does not function or percussion pressure is too low The percussion pressure--relief valve (29) does not adjust or the load--sensing line orifice (24) is clogged -- Install a pressure gauge in the LS port of the pressure--relief block. Feed the rock drill against the rear limit with maximum power. If the pressure in the LS port does not rise to the defined value (factory setting 150 bar), most likely the LS line orifice (24) is clogged or the valve (29) spool is jammed. First check the orifice (24) as follows: -- In the pressure--relief block, remove the cap from the orifice (24). -- The best way to clean the orifice is by drilling (Note! If you want to remove the orifice, do not drop it in the block channels). -- If the orifice was not clogged, check the valve (29). If necessary, clean, repair or change the valve. The system’s main pressure--relief valve (23) is leaking

ROTATION FLOW METER

-----

Install a flow meter in the pressure line of the variable displacement pump (1) and block the pressure line from the rock drill. Start the power pack and turn the percussion on. If the flow meter indicates a certain figure (i.e. several liters), the fault is most likely in the main pressure--relief valve (23). Clean, repair or change the valve.

The main percussion valve (6) does not function -- First check if the valve (6) receives control voltage. -- If the control voltage is correct, start the power pack and engage the percussion. If the pressure in the pressure gauge (39) is correct, the fault is most likely a clogged valve (6). -- Clean, repair or change the valve. -- If there is no control voltage to the valve (6), refer to electrical troubleshooting Boom--hydraulics proportional valve (31) adjustments are incorrect -- See adjustments for valve (31) control.

Gearwheel set, O-rings

Placer O-ringene (indfedtet) i tandkransens O-ringsriller. I de tandhjul hvor splines ikke er gennemgående, vendes tandhjulet så fridrejning vender ned mod huset. Placer tandhjulssættet på kardanakslen, så en tandtop i tandhjulets udvendige fortanding er lodret over mærket på kardanakslen. Drej tandhjulssættet mod uret indtil kardanakslen og tandhjul går i indgreb (15°). Drej tandkransen, så hullerne til skruerne flugter. Place the O-rings (greased) in the O-ring grooves of the gearwheel. In gearwheels with non through splines place the gearwheel with the recess in the spline hole facing down towards the housing. Place the gearwheel set on the cardan shaft so that the top of a tooth in the external teeth of the gearwheel are vertically above the mark on the cardan shaft. Turn the gearwheel set counter clockwise until the cardan shaft and the gearwheel start to mesh (15°). Turn the gearwheel rim so that the holes made for the screws line up. Die O-Ringe (eingefettet) in den O-Ring-Rillen des Zahnkranzes anbringen. Einen Zahnradsatz mit Zahanrad ohne durchgehende Verzahnung so wenden daß die Seite ohne Verzahnung gegen das Motorgehäuse gekehrt ist. Den Zahnradsatz so auf der Kardanwelle anbringen, daß sich ein Zahnkopf in der Aussenverzahnung des Zahnrads senkrecht über der Markierung der Kardanwelle befindet. Den Zahnradsatz gegen den Uhrzeigersinn drehen, bis Kardanwelle und Zahnrad im Eingriff sind (15°). Den Zahnradkranz drehen, bis die Schraubenlöcher fluchten. Placer les joints toriques (graissés) dans leurs rainures dans la couronne dentée. Si les cannelures ne sont pas du type traversant, orienter la roue dentée avec la gorge de dégagement contre le carter. Placer le jeu d’engrenages sur l’arbre à cardan de façon à ce qu’un sommet de dent de la denture extérieure du rotor se trouve au-dessus de la rainure dans l’arbre a cardan. Tourner le jeu d’engrenages en sens inverse d’horloge jusqu’à engagement de l’arbre à cardan dans la roue dentée (15°). Tourner la couronne dentée pour faire aligner les trous à vis.
