1992 Toyota Land Cruiser 70 & 80 Series Chassis & Body Repair Manual Supplement (P/N RM315E)

Toyota publication P/N RM315E covers chassis and body repair updates for the 1992 Land Cruiser Hardtop, Canvas Top, and Station Wagon following the August production changes. It covers the RJ, LJ, FZJ, PZJ, HZJ, and HDJ series.

This 409-page PDF combines the repair supplement with a Station Wagon wiring appendix. The file is partially searchable, with image-based material alongside embedded text.

• Clutch and manual transmissions: Station Wagon clutch master-cylinder repair, H150F and H151F removal and installation, plus output-shaft disassembly, inspection, and reassembly with component wear limits.

• A442F automatic transmission: Electronic-control diagnosis, stall and hydraulic-pressure tests, valve-body service, throttle-cable replacement, and torque-converter checks for the Station Wagon.

• HF2AV transfer case: Station Wagon units with ABS receive transfer-case disassembly and assembly procedures, center-differential inspection, oil-pump checks, and actuator testing.

• Brakes and ABS: Master-cylinder overhaul, load-sensing proportioning and bypass valve adjustment, ABS fault-code diagnosis, speed-sensor checks, and actuator inspection.

• Axles and propeller shafts: Front-differential removal and installation, Station Wagon front-wheel alignment data, and propeller-shaft assembly illustrations with universal-joint grease-fitting orientation.

• Body electrical systems: Cruise-control troubleshooting, combination-meter and sender tests, power-seat component checks, sub-fuel-tank diagnosis, and satellite-navigation circuit checks.

• Air conditioning: FZ-engine compressor removal, magnetic-clutch disassembly, cooling-unit service, and amplifier circuit checks, with wiring for the covered control configurations.

Toyota specifies this manual for technicians with specialized skills and certifications, using the prescribed workshop tools and test equipment.

Coverage and companion manuals

This is a chassis and body supplement. Use it with RM183E for Hardtop/Canvas Top or RM184E for Station Wagon. The foreword also references RM192E for four-door Hardtop models and RM290E for further supplemental procedures.

Engine repair belongs to the separate engine manuals. A442F internal overhaul work is cross-referenced to RM314E. These companion publications are not included in this PDF.

H150F, H151F, A442F, and HF2AV repair detail

Manual transmissions: The Station Wagon sections distinguish the H150F second-gear triple-cone synchronizer from the H151F arrangement used for first, second, and third gears. Output-shaft inspection covers gear clearances and snap-ring selection, helping identify the correct assembly details before reassembly.

Hardtop/Canvas Top installation notes warn that transfer input-gear splines can damage the transmission adapter oil seal when the assemblies are joined.

A442F diagnosis: Separate electronic-control circuits cover the 1FZ-FE and 1HD-T applications. The manual-shifting test and troubleshooting flowcharts help separate electrical-control faults from mechanical transmission problems before teardown. ECU terminal checks and shift-schedule charts add circuit and operating-condition detail to the diagnosis.

HF2AV transfer case: A section view shows the internal layout. The repair procedures cover bearing service and shim selection, center-differential checks, and differences between PTO and non-PTO assemblies.

It provides factory torque values for major underbody components, including transmission mountings, propeller shaft connections, and exhaust piping. Fluid tables include manual-transmission gear-oil specifications and separate A442F drain-and-refill and dry-fill capacities.

Station Wagon brake hydraulics and ABS testing

ABS coverage includes wiring and connector views, ECU electrical test tables, and speed-sensor waveform checks. Actuator testing calls for Toyota's ABS Actuator Checker, SST 09990-00150.

The brake section distinguishes master cylinders for vehicles with and without ABS. Its overhaul cautions identify cylinder-bore damage as a risk when pistons are handled at an angle.

Before lifting the vehicle or testing the driveline, follow the introduction's vehicle-support and full-time 4WD precautions.

Electrical diagnosis and FZ-engine air conditioning

Cruise control and auxiliary systems: Type A and Type B cruise-control troubleshooting charts lead into actuator, clutch, and position-sensor testing. Sub-fuel-tank material distinguishes FZJ70 and FZJ80 arrangements, with pump, valve, sender, and control-circuit checks.

A/C configurations: Single and dual systems, with lever or push-button controls, have application-specific circuit information. Compressor and cooling-unit illustrations support the mechanical service sections.

The Station Wagon wiring appendix adds Engine Control diagrams and harness-to-harness connector views. Application notes distinguish engine, market, and left- or right-hand-drive configurations, so diagram selection matters.

PDF page breakdown and navigation

The file contains 365 supplement pages, including four front-matter pages and two memo pages, plus a 44-page Station Wagon wiring appendix consisting of an index and 43 numbered sheets. All are already included in the 409-page total.

Embedded bookmarks navigate the main sections and individual wiring-appendix pages; appendix labels use numbered filenames. Search works in many repair-text sections, while numerous tables and illustration labels remain image-based. The cover and wiring appendix have no embedded searchable text.

Large wiring sheets require zooming to read small connector numbers and wire-color codes.
