Land Rover Range Rover 1986–1993 Workshop Manual Set (P/N SRR660ENWM)

Use Part Two alongside Part One. The base books carry the core workshop procedures, while the supplements and bulletins cover model-year changes and revised assemblies.

Model-year coverage ends with 1993. Land Rover directs owners of 1994 models to a later edition.

PDF Navigation and Wiring Detail

Finding sections and tracing circuits: Neither PDF has built-in text search or bookmarks. Use the contents pages to locate each section. Small pin numbers and wire codes require zooming. Some early EFI labels in Part One and dense main-circuit labels in Part Two remain hard to read at higher magnification.

The ZIP contains two printable PDFs totaling 1,496 pages. Part One has 918 pages and Part Two has 578. The total includes the covers, contents pages, publisher pages, and blank pages.

Engine Overhaul, Drivetrain Service, and Chassis Diagnostics

These selected workshop topics are drawn from both volumes. Other sections cover clutch service and cooling-system repairs.

• Gasoline engines and fuel systems: 3.5L V8 overhaul, Solex carburetor service, and Lucas fuel injection diagnosis, with 3.9L and 4.2L V8 updates.

• VM turbo diesels: Engine removal and overhaul, cylinder-head and liner checks, injection-pump timing, turbocharger inspection, and a dedicated fault chart.

• Gearboxes and axles: LT77 and LT77S teardown, ZF 4HP22 overhaul, LT230T and Borg Warner transfer-box service, and propeller shaft, differential, hub, and CV joint work.

• Steering, suspension, and brakes: Adwest Varamatic adjustment, pressure testing, and bleeding, plus coil-spring and anti-roll-bar service, Wabco ABS troubleshooting, electronic traction control, and air suspension calibration.

• Body and cabin equipment: Two- and four-door panel work, glass and lock service, concealed hinges, sunroofs, seats, heating and air conditioning, wipers, and washers.

• Wiring and service references: Right- and left-hand-drive main circuits, connector and harness pin references, multimeter test charts, exploded views, and factory torque, fluid capacity, and wear specifications.

Land Rover wrote the base manual for skilled technicians. The 1989 supplement advises owners with training to limit their own repairs to components that do not affect vehicle safety.

V8 Fuel Injection and VM Diesel Overhaul

V8 procedures cover cylinder heads, valve gear, timing chains, camshafts, oil pumps, pistons, and crankshafts. The fuel sections cover carburetor adjustment, injector and fuel-rail service, and emissions and evaporative-loss diagnosis.

The supplements distinguish early Lucas EFI, the hot-wire system in the catalytic exhaust supplement, and the later 14CUX system. The 14CUX continuity and sensor checks help narrow a fault to the sensor, its wiring, or the ECU before parts are replaced. With the revised ECU, a stored fault code does not illuminate the EFI warning symbol.

For the VM diesels, the manual links liner protrusion checks to head-gasket selection and gives turbocharger boost and shaft clearance checks.

Transmission Setup and Transfer Boxes

The manual gearbox chapters cover synchromesh and baulk-ring inspection, selective washer setup, and oil-pump and casing service. The ZF 4HP22 section separates in-vehicle repairs, bench repairs, and major overhaul. It includes pressure tests, pump-area leak repair, and control-unit work.

The 1989 supplement covers the revised LT77 and the Borg Warner viscous-coupled transfer box. It includes an in-vehicle coupling check and rolling-road restrictions. Axle procedures cover swivel assemblies, stub axles, and preload adjustment. Special tools include 18G1501 torque-converter handles, the LST111 oil-pump rotation and end-float gauge, the 18G1205 flange wrench, and the 18G1422 mainshaft rear oil seal installer.

ABS, Air Suspension, and Electrical Changes

Wabco ABS coverage includes depressurization, bleeding, accumulator and hydraulic power unit service, and wheel-speed sensor testing and replacement. The electronic air suspension section pairs its pneumatic diagram with ECU pin references, leak testing, fault recovery, and service for the compressor, valve block, air springs, and height sensors.

The steering supplement warns that unintended linkage rotation can damage the cruise-control spiral cassette. The air suspension chapter warns that inflating an unrestrained spring can cause spring failure and component damage. Follow the manual’s fuel, pressure, refrigerant, and vehicle-support precautions.

The later supplements cover the revised fuel tank, glass slide-and-tilt sunroof, memory and heated seats, and cruise control changes. The base books cover starting and charging systems, instruments, central locking, windows, lubricants, and maintenance schedules.

Fuel Pressure and Gearbox End-Float Examples

The 1990 14CUX EFI test specifies 34.0–38.0 psi at the fuel-feed test point just downstream of the filter with the ignition on. After the ignition is switched off, the maximum pressure drop is 10 psi in one minute.

The base ZF 4HP22 overhaul section specifies 0.2–0.4 mm of transmission axial end float during the oil-pump check. It also covers selective washer sizing for that adjustment.
