Toyota Land Cruiser FJ40, FJ43, FJ45, FJ55 F-ENGINE Factory Service Manual (P/N 98087, )

• Covers Toyota Land Cruiser FJ40, FJ43, FJ45, and FJ55 models; the engine volume addresses the improved F-series gasoline engine from No. F243298.
• Factory procedures cover engine removal, cylinder-head repair, block inspection, and crankshaft, piston, valve-train, and timing-gear overhaul.
• Transmission coverage includes three- and four-speed units, two-range transfer overhaul, and mechanical and vacuum-operated front-drive controls.
• Front-axle procedures distinguish ball-joint and Birfield joint designs; differential repair includes pinion-depth, bearing-preload, backlash, and tooth-contact checks.
• Brake sections cover hydraulic drums, the driveline parking brake, and overhaul and testing of remote vacuum boosters and later booster/tandem-master-cylinder assemblies.
• PTO-driven front-winch repair extends to the power take-off, drive shaft, worm gearing, and drum mechanism.
• Body and electrical sections cover wagon, hardtop, canvas-top, and pickup configurations, with instrument testing, wiring diagrams, and model-specific fault diagnosis.

The set combines two Toyota Motor Sales Co., Ltd. publications: an 188-page F Engine Repair Manual, Publication No. 98087, and a 344-page Chassis & Body Repair Manual—532 pages total in two PDFs.

Engine Service and Construction Details

Beyond routine tune-up, the engine sections document valve-guide replacement, cylinder boring and honing, camshaft-bearing replacement, and flywheel/bellhousing alignment checks. The special-tool listings identify Camshaft Bearing Remover & Replacer 09215-60010 for internal engine repair.

Fuel-system coverage separates earlier Land Cruiser (FJ) and gasoline-truck (FA) carburetors from the common two-barrel design introduced at Engine No. F-294920. The “Cross Section View of Carburetor” supports the component descriptions and adjustment procedures. Oil-filter service changes at Engine No. 273211, from the earlier replaceable-element arrangement to the screw-on type.

Mechanical fuel-pump testing, manifold heat-control valve inspection, and radiator, thermostat, and water-pump service are also included. Emission-control service requires a separate manual, as directed in the engine publication.

Drivetrain, Steering, and Brake Repair

Clutch coverage includes hydraulic master- and slave-cylinder repair, bleeding, and pressure-plate/release-lever adjustment. Transmission sections distinguish column- and floor-shift arrangements. The vacuum front-drive chapter covers control valves, diaphragm operation, and leak testing.

On the semi-floating rear axle, the manual covers shaft endplay and bearing replacement. Front steering-knuckle setup includes centering, shim selection, and bearing preload, using Steering Knuckle Centering Gauge 09634-60012. The centering instructions address premature axle-bushing wear caused by misalignment.

Steering-gear repair covers worm-and-sector-roller components and the separate FJ55 linkage arrangement. Leaf-spring, shackle, shock-absorber, and FJ55 rear-stabilizer procedures accompany alignment checks and toe-in adjustment.

Brake diagnosis includes booster vacuum/pressure tests and operational checks. The “Tandem Master Cylinder & Brake Booster Section View” supports the later assembly’s separate overhaul procedures.

Frame, Body, and Electrical Systems

Model-specific frame dimension diagrams accompany frame alignment and repair procedures. Door alignment, glass and weatherstrip replacement, roof removal, and seat mechanisms are treated by body style rather than as one generic body chapter.

For wagon rear-window faults, the “Tail Gate Regulator Wiring Diagram” accompanies motor, relay, safety-switch, and circuit-breaker diagnosis. Separate vehicle wiring diagrams identify FJ40(L), FJ55(L)V, FJ55LG, and Australian FJ55V configurations. Harness-routing and clamp illustrations also distinguish left- and right-hand-drive bodies.

Instrument testing covers gauges and sending units. Wiper-motor overhaul and heater-blower, heater-core, and rear-seat-heater service extend the electrical and accessory coverage.

Charging-system testing is supported by the “Wiring Diagram of Engine Electrical System.” The alternator section warns that reversed battery polarity destroys the rectifiers.

Factory Specifications and Diagnostic Data

Factory data includes component-specific torque tables, journal-specific standard and undersize bearing dimensions, wear limits, lubricant and capacity information, and electrical test specifications. Troubleshooting charts connect symptoms such as hard starting, gear noise, brake drag, and inoperative wipers with probable causes and repair checks.

Follow the manual’s precautions when handling loaded clutch springs, lifting drivetrain assemblies, or servicing brake hydraulics.
