Land Rover Defender 90/110/130 300Tdi Workshop Manual, 1996–1997 (P/N LRL 0097 ENG)

Land Rover’s factory workshop manual (P/N LRL 0097 ENG) covers the 1996–1997 Defender 90, 110, and 130 with the 300Tdi diesel engine. It includes amendment sheet LD003.97 from September 1997, which clarifies wheel nut torque figures.

300Tdi Repairs, Drivetrain Service, and Electrical Diagnosis

This selection of workshop procedures covers major service and diagnostic tasks. The manual also includes maintenance schedules for severe operating conditions and wheel-balancing procedures for steel and alloy wheels.

• Engine repair: Step-by-step instructions for camshaft drive belt and cylinder head gasket replacement, plus engine removal, valve clearance adjustment, and cylinder compression and oil pressure tests.
• Diesel fuel system: Injection pump timing, turbocharger boost checks, fuel system priming, and EGR component service, with component-location drawings and single- and twin-tank layouts.
• Clutch and gearboxes: Clutch hydraulic repairs, R380 fault diagnosis and gear lever adjustments, plus LT230 removal, installation, and oil leak diagnosis.
• Axles and steering: 110/130 rear differential overhaul, hub and CV joint service, swivel pin bearing preload adjustment, and Adwest power steering box overhaul.
• Brakes and suspension: Caliper repair, manual and pressure bleeding, transmission parking brake service, and replacement of springs, shocks, and suspension links.
• Electrical diagnosis: Immobilizer and alarm schematics, component locations, built-in alarm tests, and alternator output and charging circuit checks.
• Cooling and A/C: Coolant circulation diagrams, water pump and radiator replacement, refrigerant leak testing, and air conditioning performance checks.

Written for skilled technicians, the manual calls for owners doing their own repairs to have training and to limit their work to components that cannot affect vehicle or passenger safety.

300Tdi Engine and Fuel Injection

Engine repair also covers crankshaft seals, oil pump service, head gasket identification, and component-specific torque and clearance tables. A complete internal engine rebuild falls outside this publication’s scope.

The standard Bosch R509 and electronic-EGR R509/1 injection pumps have separate tuning data. The timing procedures identify flywheel tool LRT-12-044 and injection pump locking pin LRT-12-045/2. The belt replacement procedure links excessive belt debris to front cover misalignment caused by incorrect injection pump bracket assembly.

The fuel system section covers boost checks for the Garrett T250-04 turbocharger and shows the supply and return routing for the tank configurations. The injector procedure covers removal and refitting. Injector dismantling and spray testing are assigned to authorized Bosch dealers.

R380, LT230, and Clutch Repair

The Valeo diaphragm-spring clutch section distinguishes drag, slip, judder, and hydraulic faults. It includes master and slave cylinder overhaul procedures.

R380 component views support diagnosis, and the fault charts refer internal work to a separate overhaul manual. LT230 coverage includes external repairs and an oil seal location drawing for tracing leaks. A full internal transfer box rebuild falls outside its scope. The propeller shaft section includes universal joint overhaul and checks for driveline vibration.

Axles, Steering, and Brakes

Rear hub procedures distinguish 90 hardware from 110/130 hardware. The 110/130 rear differential has an internal overhaul procedure. The 90 rear differential and all front differentials are serviced as complete assemblies. The 110/130 procedure warns that excessive axle spreading can permanently damage the differential carrier case.

Front axle coverage distinguishes oil-filled swivel housings from later grease-filled versions. Cross-sections and exploded views show the hub, CV joint, and swivel components.

The Adwest Varamatic pressure test and insufficient-assistance fault chart help distinguish pump faults from steering box faults before parts are replaced. Steering box overhaul covers seals, valve and worm inspection, shimming, and adjustment.

Brake repair covers AP Lockheed calipers and Lucas LSC 80 servo replacement. The rear suspension section covers replacement of the optional Boge Hydromat self-leveling unit and service of its ball joints. The pressurized unit is replaced as an assembly.

Alarm Circuits and Electrical Testing

Separate schematics cover vehicles with an immobilizer spider and those with DDS (digital diesel shut-off). Both have wire-color keys. TestBook support is described for alarm and EGR diagnosis. Detailed vehicle-wide electrical information and circuit diagrams are covered in the separate Defender Electrical Troubleshooting Manual.

Cooling, A/C, and Body Repairs

The cooling section explains pressurized coolant circulation and viscous fan operation. R134a air conditioning coverage identifies the Sanden TRS105N compressor, separates left- and right-hand-drive heater and evaporator repairs, and includes pressure and temperature tables for performance testing.

Body coverage includes chassis alignment dimensions, door hardware, glazing, and wiper repairs. Observe the manual’s safety precautions for vehicle support, brake and steering work, and refrigerant handling.

Compression, Oil Pressure, and Injection Timing Preview

For the 300Tdi, the cylinder compression procedure gives an expected cranking reading of 24 bar (348 lbf/in²) with the engine at normal operating temperature and the battery fully charged. The oil pressure test specifies 1.76 bar (25.87 lbf/in²) at warm idle.

The injection timing table gives 1.54 mm of lift at top dead center for the standard Bosch R509 pump and 1.40 mm for the R509/1 pump with electronic EGR.
