Description

This Liebherr D904 D906 D914 D916 D924 D926 Diesel Engine Workshop Manual (document number 899621108, edition 05/2003) is an 899-page technical reference for the maintenance, repair and overhaul of Liebherr’s four- and six-cylinder diesel engines. It covers naturally aspirated, turbocharged and intercooled variants across the D 904, D 906, D 914, D 916, D 924 and D 926 model lines. The procedural text is in English, with German and French column headings retained in the technical tables.

Technical Data

The opening chapter consolidates engine specifications across all six model lines: displacement, bore and stroke, compression ratios, firing order, valve clearance, injection timing, injection pressures, oil pressure thresholds, coolant temperatures and torque values. Naturally aspirated and turbocharged variants are tabulated separately, so you can confirm the exact figures for a D 904 NA versus a D 916 T/TI before touching a fastener.

Inspections, Checks and Adjustments

Routine and diagnostic procedures: dry air filter servicing, fluid specifications, valve clearance adjustment (including engines with the additional engine brake system), compression testing, fuel delivery begin checks for A, MW, P, VE and H-RP43 injection pumps, injector calibration, flame glow plug and heating flange testing, piston clearance measurement, V-belt tension, thermostat testing, oil pressure relief valve adjustment, oil separator checks and a troubleshooting chart for common running faults. This is the chapter a technician reaches for first when a D 924 TI-E arrives with a drivability complaint.

Cylinder Assembly

Cylinder head removal and installation, head disassembly, valve and valve seat inspection, rocker arm and push rod checks, cylinder head rebuilding with valve seat and guide machining, piston removal and installation, cylinder liner service and connecting rod inspection with bushing replacement. Valve seat angles, installed heights and wear limits are given for each engine family.

Crankcase, Crankshaft and Camshaft

Main bearing and thrust bearing inspection, crankshaft inspection and grinding, camshaft and camshaft bushing inspection, and camshaft bushing replacement. Bearing clearances, journal diameters, hardness values and undersize steps are specified for the D 904/906 and D 914/916/924/926 families separately.

Fan Side and Flywheel Side Components

The fan-side chapter covers fan and fan hub removal, fan drive variants (fixed, fan coupling, Visco coupling), coolant pump service across four integrated timing-case versions, crankshaft pulley and vibration damper, front crankshaft seal and tachometer drive. The flywheel-side chapter covers flywheel removal, starter ring gear replacement and rear crankshaft seal replacement.

Fuel Injection System

Injection pump removal and installation for A, MW, P, VE and H-RP43 pump types, including EDC electronically controlled pumps; injection pump drive removal, inspection and repair; fuel injector removal and installation; fuel pump service; overflow valve inspection; and fuel system bleeding procedures for both inline and distributor (VE) pumps.

Pumps and Add-on Components

Air compressor, alternator (28 V, 27/55/95 A), air conditioner compressor and tension pulley, starter motor, hydraulic pump and hydraulic pump drive (flywheel housing and drive gear box installations, including shiftable drives), 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.

Disassembly and Assembly of Complete Engine

Timing and accessory drive gear box removal and installation (with coolant pump integrated in the timing case or external), intermediate gear service, flywheel housing removal, crankshaft removal and installation, camshaft and push rod removal, timing gear train alignment, and coolant and oil plug resealing on the engine block.

Turbocharger

Turbocharger removal and installation, plus repair instructions for K1/K2 and Schwitzer turbochargers, including axial and radial play measurement data and injection pump LDA (load pressure dependent full load stop) information.

Special Tools

A complete illustrated catalogue of Liebherr special tools with order numbers, covering measuring and testing instruments, removal and installation fixtures, assembly aids, cylinder head remachining tools, installation bushings and guide pins, and punches.

Electronic Engine Governor (EMR)

Removal and installation of the engine control equipment, plus a detailed system description of the LIDEC DC 5-00 electronic speed regulator used on D 924 TI-E A4, D 926 TI-E A4, D 9406 TI-E A4 and D 9408 TI-E A4 engines, including function descriptions, parameter lists, error codes, interfaces, diagnosis and replacement procedures.

Model Coverage and Serial Number Breakpoints

The manual is organised so that you always know which procedure applies to the engine on your bench. Several systems change at defined engine serial numbers: the fan drive bearing arrangement switches at S/N 89 01 2496/89 01 2497, the integrated coolant pump goes through four distinct versions at S/N 93 01 1641/93 01 1642 and 2001 02 1093/2001 02 1094, the injection pump drive changes at S/N 85 01 0269/85 01 0270, and the air conditioning compressor and alternator mounting switches at S/N 2000 01 0069/2000 01 0070. The manual lists each breakpoint in the relevant chapter so you can confirm fitment before ordering parts or starting a procedure.

Why This Workshop Manual Matters

The Liebherr D904 D906 D914 D916 D924 D926 workshop manual is the difference between a repair that holds and a repair that comes back. With 899 pages of factory-derived procedures, torque sequences, wear limits and diagnostic charts, it lets a technician work through a cylinder head rebuild, an injection pump swap, a coolant pump reseal or a complete engine teardown without guessing. Every torque angle, bearing clearance and valve seat angle is tied to a specific engine model and, where relevant, to a serial number breakpoint — so you know whether the procedure in front of you applies to the D 924 T-E A1 on your bench or the later A3 variant.

Because the manual covers naturally aspirated, turbocharged and intercooled engines across 4- and 6-cylinder configurations, one copy serves a mixed fleet. The injection system chapter alone spans A, MW, P, VE and H-RP43 pumps — a range that would otherwise require three or four separate documents. The special tools chapter is cross-referenced to every procedure that calls for a non-standard puller, punch or alignment fixture, making it practical to order what you need before the engine comes apart.
