Wheel loaders L60E, L70E och L90E have articulated frame steering and four-wheel drive. The engine is a six-cylinder, four-stroke, direct-injection, turbocharged diesel engine of the type D6D. The transmission is hydro-mechanical where all gears are in constant mesh. Its type designation is HT93 for L60E, HT95 for L70E and HTE202 for L90E. There is a single-stage hydraulic torque converter between the engine and the transmission. Front and rear axles have fully floating drive shafts with planetary gears in the wheel hubs. The front axle is equipped with a differential lock. The service brakes on these machines are wet type disc brakes. The service brakes are built into each wheel hub. The parking brake on L60E and L70E is a disc brake positioned externally on the front output shaft of the transmission. On L90E the parking brake is positioned internally on the front output shaft of the transmission. The steering system is hydrostatic with a variable load-sensing axial piston pump and two hydraulic cylinders (steering cylinders).

The machine has a 24 V electrical system with two 12 volt batteries located on each side of the rear frame behind the rear wheels. The battery disconnect switch is located under the radiator casing. Voltage feed takes place via a fuse box located in the engine compartment. The fuse box contains main fuse as well as fuses for preheating coil and secondary steering pump. Relays and fuses are placed in the electrical distribution box behind the operator's seat and are accessible when the cover is opened. On the inside of the cover, a decal showing which current-consuming device is connected to respective relays and fuses. The relays in the electrical distribution box are interchangeable. The components are marked according to function group. The first digit in the marking, i.e. SE201, indicates that the component belongs to engine (group 2). Other digits are sequential numbers. There are also components with a four-digit designation, i.e. SE2203. The first two digits indicate function group and the other indicate sequential numbers.

Instru Instrumen mentt contr control ol unit unit I-ECU I-ECU The machine electronics contain three control units that communicate with each other via two data links. Each control unit processes values from sensors and operating controls, which help to control components so that proper function is maintained. The control units in the system include the instrument control unit I-ECU, the vehicle control unit V-ECU and the engine control unit E-ECU. The vehicle electronics facilitate troubleshooting through an extensive diagnostic system. The operator is informed of the location of the malfunction with a warning light, together with a text message. The service display unit or computer (VCADS Pro) can be connected via service sockets located in the electrical distribution box behind the operator's seat. is located in the instrument panel and contains software for presenting operator information on the display panel, including warning and control lights. The control unit receives information from the other control units via data link. is located on intermediate wall behind the radiator and contains software for controlling engine functions. The control unit receives information from the engine sensors as well as from a data bus. The control unit also sends information to the other control units via data buses.

The vehicle control unit is connected to the other control units via data bus. for programming, changing parameters, reading error codes, testing and checking components, etc. takes place using VCADS Pro. Reading input and output signals on the V-ECU, settings, reading vehicle information, etc. is performed with the service display unit. If a malfunction occurs in any system, information is sent via the data link and it can be read by the operator on the operator's display panel, or by using the service display panel and VCADS Pro.

Vehicle electronics are based on the principle that all communication between controls units takes place via two data buses. The machine's three control units are connected to the buses to be able to communicate with each other. Communication between the different control units as well as reporting from control units to service sockets takes place on data buses CAN/J1939 and J1708/J1587. The buses follow SAE standards and consist of two pair-twisted cables. The purpose of the twisted cabling is to protect the bus from electrical interference. If a malfunction should occur in the system, a signal is sent on the information bus, making it possible to read the information, either on the operator's instruments or via the service display unit or VCADS Pro. The figure shows the principle for how the control units and service sockets are connected to the buses.
System control signals are sent via this bus. The control bus is very quick, which is necessary for control of

the entire system to work and quickly adapt to changing conditions. The main communication alternative is the CAN/J1939 bus. However, for E–ECU, some control data is only sent on the J1708/J1587 bus.
The information bus is connected to the control units and service sockets. Information and diagnostic signals are sent on this bus. In addition, some control data is sent from the engine control unit via this bus. The bus also functions as a "back-up" for the control bus, if it should fail for some reason. The system status is continuously updated and available for reading via the information bus. By connecting the service display unit or VCADS Pro to service sockets, it's possible to read error codes, perform tests, empty logged information, download parameters and download software.

Software is stored in the control units E-ECU, I-ECU and V-ECU. To determine which software is installed in the machine, the part number is read off from the software (Main software) in the machine control units V-ECU and I-ECU with the service display unit in menu figure "ECU IDENTITY" or with the service tool VCADS Pro. Also, the part part number of of the software software (Main software) software) for the the engine's control unit E-ECU can can be read off using VCADS Pro. Updating of the machine's software is handled through release of a new edition. The releases are designated with Year:edition, for example, R2001:5 and gets a new part number. Updating of software for control units takes place through downloading of new software from VOLVO with VCADS Pro.

Used to a certain extent. Electric event is that the lead has passed something, for example, a switch or a relay which may have resulted in an electrical change (electric event). For each such electric event, the digit changes, 1 becomes 2 and so on.
Página 1 de 2
Cables and components in wiring diagrams are designated according to function group assignment.
Lead marked, for example, 30–20 indicates that there is 30 feed via 20 to a component. After the component, the designation may be, for example, 6101 where 6 indicates function group, 01 is running number.
Component marked SW601 (for example), SW is switch, 6 indicates function group, 01 is running (sequential) number.

If the machine has insufficient pulling power the fault could be found in the engine or transmission. Check engine stalling speed, see Section 2. Verify hydraulic pressure is not outside of the specification limits and that the brakes are not applied (service brake or parking brake). 1. If the stall stalling ing speed speed is too too low, low, the fault fault can can be found found in the engin engine. e. 2. If the engine engine stalling speed speed is within within or higher higher than the specified limits, limits, the fault can can be found found in the transmission.
Check that 1st gear can be engaged. Insufficient pulling power in combination with the transmission running hot indicates a fault in the torque converter. Start by checking torque converter pressure.
Electrical malfunction. malfunction. Defective gear selector valve Hydraulic or other fault in the clutch shaft Check the main pressure and the clutch pressure for the clutch in question.
If the correct clutch pressure is obtained, the fault is in the clutch (slipping). Correct main pressure and low clutch pressure could be due to leakage between the oil distributor and clutch shaft or in the gear selector valve. If the correct main pressure is obtained but no clutch pressure is present, an electrical fault or a fault in the gear selector valve could be the cause.
Electric malfunction (loose connection) etc. Binding valve spool in the gear selector valve. Leakage between oil distributor and clutch shaft (functions when the oil is cold, malfunctions when the oil heats).
