• 70. Hydraulics — list of hydraulic sheets, FP HP feed block, accumulators, 9-component distributors, 4-component electro-proportional distributor PVG100/32, 3-component deflector distributor, brake master cylinder, cooling engines, hydraulic pumps, steering, safety valves, discharge valves, compensating isolation valve, flow rate control valve, dynamic selection valve, ventilation cut-off, hydraulic diagrams for all eight variants, component locations, control and adjustment, pressure connector adjustment, removal, specific tooling
• 80. Electricity — fuses and relays (cab, engine hood 75D, engine hood 100D), ECU inputs/outputs, technical sheets for electrical components, CAN and LIN operating diagrams, coding examples, cable marking, position by diagram, full electrical diagrams for MT 100D, MT A 100D and MT HA 100D, component locations, control and adjustment, removal and refit, troubleshooting with DTC codes for main and auxiliary ECU, engine error codes, air conditioning error codes, specific tooling
• 85. Operator Station — air conditioning operation description, safety measures for handling R134a, schematic diagrams, HVAC component locations, automatic air conditioning location, condenser component, control and adjustment, evaporator temperature sensor check, tightening torques, removal and refit of dashboard trim, cab casings, air conditioning unit, cab, condenser, motor and electric window, troubleshooting
• 90. Chassis — counterweight tightening torque, removal of engine hood, 75D engine housing, 100D engine housing
• 110. Additional Equipment
• 120. Diagnostic Tools and Software — diagnostics case kit, USB Link 2 box, component diagnostics box

Across all of these groups the manual supplies the technician with the values, procedures and illustrations needed to actually work on the machine rather than just read around it. Tightening torques are given in N.m with imperial equivalents alongside, pressure connector values are tabulated with minimum and maximum thresholds, and adjustment procedures are broken down step by step. The hydraulic schematics cover the circuit in colour-coded detail — suction, boost, high pressure, low pressure, pilot, cooling, return and drainage lines are distinguished — and the electrical diagrams show connector pins, wire numbers, splice points and connector names so a fault can be traced from an ECU pin all the way to the component. The troubleshooting sections publish the DTC fault codes for the main SPU 40-26 ECU, the auxiliary SPU 25-15 / SPU 40-26 ECU and the engine ECU, so a diagnostic tool reading can be interpreted directly against the manual.

Engines and Drivelines Covered

The manual deals with both the 75D (55.4 kW / 75 hp) and 100D (74.4 kW / 101 hp) four-cylinder Stage V engines, 3621 cm³, direct injection, turbocharged, managed electronically and using DOC, DPF and — on the 100D — SCR with DEF. Engine ECU pinouts for both versions are provided in the Electricity chapter. The transmission chapter separates the mechanical transmission used on non-HA versions (with the PSR gearbox and torque converter) from the hydrostatic transmission used on HA versions (A4VG 71-180 series 32 pump and A6VM series 71 motor), each with its own pressure connector layout, adjustment procedures and tightening torques. Axle type 212 is documented in the supplier documentation listing.

What This Manual Enables

With this service manual a technician can carry out the full range of workshop operations on an MT 1440 or MT 1840. Engine work includes removal of the exhaust line, radiator, hydraulic engine-fan assembly, starter, belt casing, attachment belt, air conditioning belt, alternator, fuel filter, air conditioning compressor and expansion tank, along with DEF pump cleaning and the exhaust assembly tightening torques. The transmission chapter covers mechanical and hydrostatic gearbox removal and the adjustment of the hydrostatic pump and motor. Brake work covers bleeding the service and parking brake circuits, adjusting the parking brake and putting the truck into freewheel for towing. The lift structure chapter supports the removal and refit of the triplex 14 m and quadruplex 18 m booms, telescope removal, chain wear checking and chain tension presets. The hydraulic chapter covers removal of the hydraulic oil tank and the main hydraulic distributors. Electrical work is supported by full connector pinouts, fuse and relay listings and DTC fault tables. The operator station chapter covers the HVAC system, cab removal and window lift motor replacement.

Correct procedures and correct specifications are what separate a repair that lasts from one that comes back. This manual gives the tightening torque for the counterweight at 950 N.m ± 95 N.m, the boom foot pad clearance ranges, the master cylinder and service brake pressures, the hydrostatic pump HP relief valve setting of 508 bar, and dozens of other values that are specific to this machine and cannot be guessed. Where a component has a removal sequence — the boom telescope extraction, the DEF pump flush, the strain gage bonding and calibration — the manual walks through it in order, with the tooling and the intermediate measurements called out.
