1987–1992 Range Rover Repair Manual (P/N SRR652USWM A)

This Land Rover factory workshop manual covers U.S.-market 1987–1991 model-year Range Rover vehicles. The title page identifies Publication Number SRR652USWM A and states that suffix A incorporates amendments through September 1990. Model-year additions are marked in the page headers, allowing the baseline 1987 procedures to be separated from later 1988–1991 changes. Land Rover describes the manual as being for skilled technicians; owners undertaking their own repair work need prior mechanical training, and safety-critical steering, brake, or suspension repairs are not presented as untrained DIY work.

File and Page Scope

The package contains 30 section PDFs totaling 864 PDF pages. The standalone 36-page A.R.A. air-conditioning file repeats the same section included within the 44-page HVAC file, leaving 828 unique manual pages.

Key Workshop Coverage

• V8 engine and support systems: Covers engine removal and installation, complete internal teardown and overhaul, cylinder heads and valve gear, timing gears and camshaft, pistons and connecting rods, crankshaft inspection, oil-pump testing, cooling-system service, and exhaust work. Separate specification and tuning material addresses the 3.5-liter V8 and the 3.9-liter data introduced for 1989.
• Fuel injection and emissions: Provides Lucas 13CU, 14CU, and 14CUX system descriptions, ECU-harness continuity tests, fault-isolation charts, engine-setting procedures, fuel-pressure testing, and service for the airflow meter, throttle assembly, injectors, pump, rail, regulator, and tank. The 14CUX coverage includes the 17EM fault-code display and the ECU change after VIN 451518 that eliminates the tune-select resistor.
• Automatic and transfer gearboxes: Breaks ZF 4HP22 repair into in-vehicle work, removed-gearbox service, and major overhaul. Coverage reaches the torque converter, pump and bellhousing, valve body/control unit, governor and parking mechanism, gear train, freewheels, and A–F clutch assemblies. The LT230 section adds removal, complete internal overhaul, bearing setup, center differential work, and differential-lock and neutral-switch adjustment.
• Axles, steering, and suspension: Details differential overhaul and pinion setup, front and rear hubs, discs, axle shafts, constant-velocity joints, swivel housings, and ABS-specific hub arrangements. It also covers power-steering pressure tests, pump and steering-box repair, system bleeding, radius arms, springs, shock absorbers, anti-roll bars, and the rear self-leveling unit.
• Conventional and ABS brakes: Includes dual-circuit brake bleeding, master-cylinder and servo overhaul, front and rear caliper repair, pressure-reducing valve service, and transmission-mounted parking-brake overhaul and adjustment. The 1990 WABCO four-channel ABS material covers system bleeding, warning circuits, wheel sensors, hydraulic booster, pump, accumulator, and component removal and replacement.
• Electrical, HVAC, and accessories: Supplies year-specific main circuit diagrams for 1987–1991, electrical-equipment locations, relay and fuse identification, and repair coverage for starting, charging, ignition, lighting, instruments, windows, locks, seats, sunroof, wipers, and Hella CR66 cruise control. The A.R.A. section covers refrigeration-system diagnosis, leak testing, evacuation, charging, and component removal and refitting.
• Body repair and scheduled service: Covers chassis and monocoque panel repair, factory weld locations, bolt-on aluminum panels, doors, tailgates, glass, trim, seat belts, and sunroof timing. Maintenance material distinguishes 49-state and California schedules and includes later Borg Warner transfer-case service additions.

Factory References, Diagrams, and Tools

Reference sections provide component-specific torque tables, fluid and refrigerant capacities, approved lubricants, shift-speed data, pressure-test specifications, bearing preload and end-float data, wear limits, clearances, and electrical test values. The service-tool catalog identifies equipment such as 18G1501 torque-converter handles, LST118 transmission holding fixture, 18G1423 center-differential locknut socket, and 18G191 pinion-setting gauge. Dimensioned drawings are included for locally fabricated transmission lifting and holding fixtures.

Named visuals include the A.R.A. refrigeration-cycle and electrical supply switch/fuse schematics, ZF clutch-assembly exploded views, Brake Pipe Layout RR2222E, ABS booster circuit RR2669M, and the 1991 Main Circuit Diagrams RR2942E/RR2943E.

Scope and Repair Cautions

The LT230 receives a full internal overhaul chapter. Borg Warner coverage is narrower: ratios, capacity and lubricant data, oil service, towing and dynamometer notes, selected tool references, and removal/refitting of the combined ZF/Borg Warner transmission assembly are included, but not a complete Borg Warner internal overhaul.

The A.R.A. instructions warn that operating the system with its service valves in the OFF position can severely damage the compressor. The EFI continuity section likewise cautions against probing the faces of the ECU connector sockets, which can damage the terminals and create poor connections. R-12 A/C and pressurized ABS work require trained personnel and the correct service equipment, with applicable refrigerant-handling requirements observed.
