Description
Lombardini LDW CHD Engine Workshop Manual provides the manufacturer’s repair and overhaul instructions for LDW 1503, LDW 1603, LDW 2004, LDW 2004/T, LDW 2204 and LDW 2204/T diesel engines. This sixth-edition, revision 5 publication contains technical information updated to 1 December 2009.
Produced for trained technicians and authorised after-sales workshops, the manual supports engine disassembly, inspection, assembly, overhaul, replacement and tuning work. Procedures are accompanied by illustrations, measurements, settings and technical data relevant to the listed naturally aspirated and turbocharged CHD-series engines.
This is an engine-only workshop manual. Its coverage relates to the Lombardini power unit and associated fuel, lubrication, cooling, starting and charging systems rather than the complete host machine.
ENGINE DISASSEMBLY AND REASSEMBLY
The principal overhaul section covers dismantling, inspection and correct reassembly of the engine’s internal and external components. It includes dimensional checks, clearances and timing information required during professional repair work.
- Cylinder head removal, inspection and tightening
- Valves, guides, seats, springs and rocker assembly
- Pistons, piston rings, pins and connecting rods
- Cylinders, crankshaft, journals and main bearings
- Crankshaft end float, thrust bearings and oil seals
- Camshaft removal, journals, bushes and end play
- Camshaft and valve timing procedures
- Flywheel, front cover, pulleys and timing gears
- Speed governor components and adjustment data
- Dynamic balancer information for applicable four-cylinder engines
TURBOCHARGER
Turbocharged LDW 2004/T and LDW 2204/T applications are supported by a dedicated turbocharger section. This identifies the assembly and provides relevant testing and adjustment information.
- Turbocharger construction and components
- Turbocharger testing
- Wastegate actuator setting
- Control-rod stroke adjustment
LUBRICATION AND COOLING SYSTEMS
The manual provides layouts and workshop checks for the systems responsible for engine lubrication and temperature control.
- Lubrication circuit layout
- Oil pump and rotor-clearance inspection
- Oil-filter cartridge
- Oil-pressure regulating valve
- Oil-pressure testing and model-specific pressure curves
- Cooling-system layout
- Coolant circulation pump and thermostat
- Expansion tank and pressure cap
- Cooling-system leak checks
FUEL AND INJECTION SYSTEM
Fuel-system coverage extends from the low-pressure supply circuit to injection-pump servicing, delivery balancing, injection timing and injector setting.
- Fuel feed pump, filter and injection circuit
- Electric 24-volt fuel pump
- Injection-pump removal and disassembly
- Injection-pump component reassembly
- Control rod and non-return valve
- Injection-pump delivery checks and equalisation
- Low-pressure injection timing checks
- Timing correction using pad thickness
- Pin-type injector inspection and setting
- Injection-pump test data
ELECTRICAL AND STARTING SYSTEMS
Engine electrical information covers specified 12-volt and 24-volt charging, starting and preheating equipment. Wiring diagrams and characteristic curves are included for the listed component types.
- Marelli and Iskra alternators
- Bosch and Iskra starter motors
- 12-volt and 24-volt wiring diagrams
- Voltage-regulator characteristic curves
- Preheating control-unit connections
- Glow plugs and controller relay
- Key-switch electrical layouts
- Coolant temperature switches and sensors
TESTING, SETTINGS AND TROUBLESHOOTING
The Lombardini LDW CHD Engine Workshop Manual includes troubleshooting guidance, adjustment procedures and reference values used when diagnosing faults or returning an overhauled engine to its prescribed settings.
- Likely engine anomalies and symptoms
- Possible causes and troubleshooting guidance
- Idle and full-speed settings under no load
- Fuel-delivery limiting adjustment
- Torque-adjusting device settings
- Stop setting
- Technical specifications and performance diagrams
- Power, torque and specific fuel-consumption curves
MAINTENANCE AND WORKSHOP REFERENCE
Supporting information covers routine and extraordinary maintenance, approved fluids, storage and workshop assembly data.
- Ordinary and extraordinary maintenance schedules
- Lubricant classifications and prescribed lubricant
- Fuel, biodiesel and low-temperature recommendations
- Coolant requirements
- Engine storage and return to service
- Main tightening torques
- Standard coarse- and fine-thread torque tables
- Sealant use and special tools

The Lombardini LDW CHD Engine Workshop Manual is a focused technical reference for engine rebuilders, plant workshops and experienced service engineers working on the listed CHD-series diesel engines. It provides the manufacturer’s sequence of repair operations together with the measurements, settings and diagrams needed for controlled workshop work.
Always confirm the engine identification and exact variant before beginning repairs, particularly where the manual distinguishes between turbocharged engines, hydraulic or mechanical tappets, and different electrical equipment specifications.
