1985 Toyota Truck & 4Runner (22R and 22R-E engine) Repair Manual (P/N 36246A)

• Covers 1985 Toyota Truck and 4Runner gasoline models with carbureted 22R and EFI 22R-E engines, including 2WD/4WD, manual/automatic, and Federal/California/Canada system variations.
• Guides cylinder-head removal and overhaul, valve and camshaft inspection, timing-chain service, and piston, crankshaft, and cylinder-block repair, with the related checks and assembly specifications.
• Details carburetor rebuilding and 22R-E TCCS diagnosis, including trouble-code retrieval, ECU terminal tests, fuel-pressure checks, and inspection of injectors, the cold-start system, air-flow meter, relays, and sensors.
• Separates W46/W55/W56 and G52 manual-transmission teardown and rebuilding from A43D automatic-transmission testing and overhaul, then covers clutch hydraulics, transfer-case rebuilding, and propeller-shaft service.
• Provides 2WD- and 4WD-specific repair procedures for front and rear axles, free-wheeling and automatic locking hubs, Birfield axle shafts, steering-knuckle setup, differential adjustment, suspension, steering, and hydraulic brakes.
• Includes body-electrical diagnosis, cruise control, 4Runner back-door power-window and rear-wiper interlocks, factory winch service, and R-12 air-conditioning diagnosis and component repair.
• Supplied as a 1,025-page Toyota factory repair manual PDF, Publication No. 36246A, with service-specification tables, SST/SSM references, A43D hydraulic circuits, and full-system electrical wiring diagrams.

Engine, Fuel, and Maintenance Detail

Toyota organized this manual around a step-by-step “fast track” for the experienced technician. It is best suited to professional mechanics and experienced owners who can use pullers, presses, electrical meters, pressure gauges, and vehicle-support equipment safely. The opening chapters provide normal- and severe-service schedules, general maintenance checks, lift and support locations, and component-level troubleshooting before the major repair sections begin.

The engine material goes well beyond tune-up data. It covers compression and idle-emissions diagnosis, cylinder-head disassembly and inspection, valve and guide work, camshaft and rocker service, timing-component installation, and complete rotating-assembly inspection. Separate fuel and emissions chapters distinguish the 22R carburetor from the 22R-E electronic system. The carbureted configurations receive region- and transmission-specific coverage for mixture control, EGR, air suction, catalyst systems, high-altitude compensation, choke controls, auxiliary acceleration, deceleration fuel cut, and the cold-mixture heater. EFI coverage adds diagnostic-code charts, volt/ohmmeter fault isolation, fuel-delivery repair, and air-induction and ECU-controlled component tests.

Drivetrain, Chassis, and Body Systems

The A43D section combines stall, time-lag, hydraulic-pressure, shift-point, road, and electrical-control tests with on-vehicle repair and full internal overhaul. Manual gearboxes are treated by family, including gear, shaft, bearing, synchronizer, fork, and end-play inspection. The 4WD transfer chapter follows removal through disassembly, measurement, seal and bearing service, reassembly, installation, and final road testing.

Chassis procedures reflect the actual configuration differences. The 2WD front end uses torsion-bar suspension, while 4WD coverage includes the solid front axle, leaf springs, free-wheeling or automatic locking hubs, axle shafts, and knuckle-bearing alignment and preload. Rear-axle work covers axle-shaft service and differential ring-and-pinion setup for the listed 1/2-ton, 1-ton, cab-and-chassis, and 4WD applications. Brake chapters address master-cylinder and booster repair, system bleeding, front and rear brake variants, parking-brake adjustment, and the load-sensing proportioning and bypass valve.

Schematics, Tools, and Shop Data

Diagram coverage includes the A43D D-range first-gear hydraulic circuit, EFI and emission-control circuits, cruise-control fault charts, the 4Runner back-door window/rear-wiper interlock, the winch control and magnet-switch circuit, and 22R/22R-E air-conditioning circuits. Body sections also cover doors, removable cover top, 4Runner quarter windows, glass, seats and belts, roll-over bar, and 2WD/4WD body dimensions.

The specification appendix consolidates torque data, capacities, clearances, wear limits, preload and backlash specifications, electrical test values, and approved lubricants. The SST/SSM appendix identifies the factory tooling and materials, including SST 09634-60013 for 4WD steering-knuckle alignment and preload, SST 09992-00093 for A43D hydraulic testing, and SST 07110-78010 for R-12 manifold-gauge work.

Two factory cautions are especially relevant during driveline repair. The transfer input-gear splines can damage the adapter rear oil seal during removal or installation, and the rear-differential pinion nut must not simply be backed off after the bearing spacer has been compressed; an over-compressed spacer leaves the pinion bearings with incorrect preload. Use the specified lift points, calibrated test equipment, and proper fuel, brake, driveline, and R-12 service precautions for the work being performed.
