Technical Data (Chapter 1)

The opening chapter lays out engine data tables for every covered variant: bore and stroke, displacement, compression ratio, firing order, valve clearance (intake and exhaust, cold), injection timing, injection pump and governor specifications, oil pressure, coolant capacity, and torque values for standard and fine-thread fasteners. Tables use trilingual headers (German, English, French) and give metric and imperial units where applicable. Also included: cylinder identification, engine number and crankcase number locations, and the layout of the engine data plate.

Inspections, Checks and Adjustments (Chapter 2)

Routine and diagnostic work: dry air filter servicing, fluid specifications, sealing and locking compounds, valve clearance adjustment (including engines with the ZBS engine brake), compression pressure testing, fuel injection timing (for A, MW, P, VE, H-RP43 and EDC pumps), injector calibration, flame glow plug and heating flange checks, piston clearance measurement, V-belt tension, thermostat testing, oil pressure relief valve adjustment, oil separator service, and a troubleshooting matrix by symptom.

Cylinder Assembly (Chapter 3)

Cylinder head removal and installation, disassembly and assembly, valve and valve seat inspection, rocker arm and push rod checks, cylinder head rebuilding including valve seat machining and valve guide replacement, piston removal and installation, cylinder liner removal and installation, repair of insufficient liner protrusion, and connecting rod inspection with bushing replacement. Torque sequences and angle-tightening methods are given throughout.

Crankcase, Crankshaft and Camshaft (Chapter 4)

Main bearing and thrust bearing inspection, crankshaft inspection and grinding (including hardness testing and undersized bearing shells), camshaft and camshaft bushing inspection, and camshaft bushing replacement using the dedicated removal and installation device.

Components — Fan Side and Flywheel Side (Chapters 5 and 6)

Fan and fan hub removal and installation, fan drive disassembly and assembly (fixed drive with ball bearings, fixed drive with bushings, Visco coupling and fan coupling variants), coolant pump removal and installation across all four pump versions, pulley and vibration damper service, front and rear crankshaft seal replacement, tachometer drive repair, coolant shut-off valve service, flywheel removal and installation, and starter ring gear replacement.

Fuel Injection System (Chapter 7)

Injection pump removal and installation for inline pumps, distributor (VE) pumps, MW pumps, P pumps, and H-RP43 control-sleeve pumps with EDC. Also covers injection pump drive removal, inspection and repair, overflow valve replacement, fuel injector removal and installation, fuel lift pump service, and fuel system bleeding procedures.

Pumps / Add-on Components (Chapter 8)

Air compressor, alternator (28 V, 27 A / 55 A / 95 A), air conditioning compressor, starter, hydraulic pump and hydraulic pump drive, oil pan, lubrication oil lines, lubrication oil pump, piston cooling nozzle, oil pressure sending unit, oil filter mounting base and oil cooler, exhaust manifold, air intake manifold, coolant manifold, and engine brake removal and installation.

Disassembly and Assembly of Complete Engine (Chapter 9)

Timing and accessory drive gear box removal and installation, intermediate gear service, flywheel housing removal, crankshaft removal and installation, camshaft and push rod removal and installation, timing and accessory drive gear train identification, and coolant and oil plug resealing on the engine block.

Turbocharger (Chapter 10)

Turbocharger removal and installation, service guidelines for turbocharged engines, K1/K2 and Schwitzer repair instructions with axial and radial play limits by turbocharger size, and the load-pressure-dependent full-load stop (LDA) on the injection pump.

Special Tools (Chapter 11)

A complete illustrated catalogue of the Liebherr special tools referenced throughout the manual, organized by function: measuring and testing tools, removal and installation fixtures, assembly aids and special wrenches, cylinder head remachining tools, installation bushings and guide pins, and punches. Each tool is listed with its order number and a cross-reference to the engine models it applies to.

Electronic Engine Governor (Chapter 12)

Removal and installation of the engine control equipment, plus the full LIDEC DC 5-00 system description: electronic speed regulation, start/stop logic, full-load characteristic curves, P-grade, temperature-dependent idle speed increase, charge-air-pressure and speed-dependent injection quantity limitation, atmospheric-pressure-dependent reduction, cold-start with flame start unit, emergency operation, engine protection functions, parameter list with measuring values, error codes, interfaces (ISO 9141 diagnosis, CAN-Bus ISO 11898), wiring diagrams, pin configurations, and error diagnosis.

Who This Manual Is For

This Liebherr D904 / D906 / D914 / D916 / D924 / D926 diesel engine workshop manual is written for mechanics and technicians already familiar with standard engine repair who need the manufacturer’s exact procedures, torque values and wear limits. Whether you are adjusting valve clearance, setting fuel injection timing, pulling a cylinder head, overhauling a coolant pump or chasing an EDC fault code, the manual provides the step-by-step sequence, the special tool number and the specification you need.

Why This Manual Matters

Liebherr diesel engines are built to tight tolerances and used in demanding construction equipment. Guessing at torque values, reusing stretched cylinder head bolts, or installing the wrong cylinder head gasket type can turn a straightforward repair into a costly failure. This manual gives you the correct tightening sequences and angle-torque steps, the cylinder liner protrusion measurements, the injection pump timing marks and the piston clearance limits — the information that separates a repair that lasts from one that comes back.

The 926-page scope covers six engine model series and their naturally aspirated, turbocharged and turbocharged-intercooled variants, including the electronic EDC-governed versions. Technical data tables use trilingual headers (German, English, French) for quick cross-reference, while all procedures are written in English.
