Toyota B, 3B, 11B, 13B & 13B-T Diesel Engine Repair Manual (1994)

Toyota’s factory engine repair manual covers the B, 3B, 11B, 13B, and 13B-T diesel engines used in the Land Cruiser, Dyna, and Coaster applications listed above. The title page carries a 1994 Toyota copyright.

PDF Bookmarks, Search and Diagram Detail

Bookmarks and circuit labels: Embedded PDF bookmarks provide chapter and individual-page navigation. PDF text search is not available. Small terminal numbers, wire codes, and component labels in the checked pre-heating, EDIC, and charging circuits are readable when enlarged.

The ZIP contains one printable, English-language PDF with 338 pages, including two unnumbered opening pages and the service-specification, standard-bolt-torque, and SST/SSM appendices.

Diesel Overhaul, Injection Calibration and Electrical Diagnosis

The following selected repair topics show the manual’s coverage rather than reproduce its full contents. Other examples include air-conditioner idle-up adjustment and intake-shutter vacuum-switching-valve tests.

• Diesel diagnosis and tune-up: Symptom-based fault charts, compression testing, valve-clearance and injection-timing adjustment, idle and maximum-speed settings, and intake-restriction checks.

• Cylinder head and block: Step-by-step procedures for head overhaul, valve and guide inspection, piston and bearing work, cylinder-liner replacement, boring, and short-block assembly.

• Timing gears and camshaft: Gear-train removal and installation, backlash and thrust-clearance inspection, camshaft checks, automatic-timer alignment, and front oil-seal replacement.

• Fuel injection: Nozzle pressure, leakage, and spray-pattern tests; fuel-filter and feed-pump service; automatic-timer adjustment; and injection-pump disassembly, inspection, reassembly, and calibration.

• 13B-T turbocharger: Boost diagnosis, wastegate-actuator checks, impeller inspection, removal and installation, oil and coolant plumbing, and indicator/warning-light fault tracing.

• Cooling and lubrication: Coolant service, water-pump overhaul, thermostat and radiator tests, oil-pressure diagnosis, oil-pump repair, and oil-cooler and relief-valve service.

• Starting and charging: Pre-heating and EDIC diagnosis, starter overhaul and performance tests, alternator repair, regulator checks, and model-specific electrical circuits.

The procedure format is written for experienced technicians; injection-pump repair additionally requires considerable skill and a special test bench.

Mechanical Inspection and Overhaul

Diagnosis before disassembly: The diesel fault charts connect starting, smoke, power, idle, and shutdown symptoms with checks and referenced repair sections. They support fault isolation before injection-pump work is considered.

Compression procedures distinguish the glow-plug access used on B/3B engines from the injector access used on the other engines. Tune-up coverage also separates injection-timing settings by engine and high-altitude-compensator configuration.

Internal engine work: Head repair extends to valve guides, seats, springs, rocker shafts, push rods, manifolds, and head-flatness checks. Block inspection covers connecting-rod and main bearings, piston rings, rod bushings, crankshaft and camshaft bearings, and the rear oil seal.

Cylinder-liner work includes pressing, protrusion measurement, boring, and honing. Bearing selection uses the manual’s identification marks and color groups; assembly illustrations show bearing oil-hole and thrust-washer groove orientation.

Incorrect cylinder-head bolt removal order can cause warpage or cracking, a repair risk specifically addressed in the head-removal instructions.

Injection-Pump Calibration and Turbocharger Service

The 101-page fuel section separates B/3B nozzle procedures from those for the other engines. Pump repair distinguishes the governor arrangements and provides pre-stroke, injection-interval, delivery-volume, and governor adjustments.

High-altitude-compensator procedures and 13B-T boost-compensator settings retain their configuration-specific conditions. Pump-body inspection includes precision parts, bearings, seals, and control-rack movement; these are bench procedures rather than ordinary on-vehicle adjustments.

The pump instructions emphasize keeping precision components in order and avoiding contact with plunger and delivery-valve sliding surfaces, where contamination or scoring can compromise operation.

For the turbocharger, the manual distinguishes intake and exhaust restrictions, leakage, actuator faults, and impeller condition. Its diagnostic notes also distinguish crankcase-ventilation oil mist from evidence of turbocharger seal leakage.

Cooling, Lubrication and Electrical Variants

Water-pump overhaul distinguishes the bearing designs and fan arrangements. Lubrication coverage separates B/3B gear-type oil pumps from the rotor-type pumps used on the other engines and includes the 3B/13B-T oil-nozzle and check-valve system.

Electrical sections distinguish B/3B super-glow and fixed-delay systems from the intake-heater systems. They also address EDIC-equipped B/3B applications, the non-EDIC B fuel-cut diaphragm, and the non-EDIC 3B overinjection magnet.

Reference illustrations include diesel electrical diagnosis flows, the turbo indicator fault chart, pre-heating timer characteristic diagrams, governor characteristic charts, and model-specific charging circuits. Alternator procedures distinguish units with and without IC regulators; relay coverage includes starter and charge-light relays and the BJ60 ignition main relay.

Workshop References and Scope

The specification appendix brings together torque data, capacities, clearances, wear limits, injection-pump calibration, and starter and alternator test values. SST listings include injection-pump stand 09241-76022, compression gauge set 09992-00023, and turbocharger pressure gauge 09992-00241.

This is an engine repair manual, not a complete vehicle workshop or wiring manual. Transmission, axle, brake, chassis, body, and full-vehicle electrical repairs fall outside its coverage. Block overhaul begins with preparation for engine-stand disassembly rather than vehicle-level engine removal.

Verify lifting and engine-stand equipment before internal engine repair, and isolate the battery before starting- or charging-system work.

Selected Gear, Liner and Turbo Inspection Limits

Timing-gear inspection specifies standard backlash of 0.058–0.162 mm. Cylinder-liner replacement includes a ridge-protrusion specification of 0.01–0.10 mm, alongside the pressing and subsequent boring procedures.

For the 13B-T turbocharger, the impeller-wheel inspection gives an axial-play limit of 0.13 mm. These examples show the component-specific inspection data supplied with the repair procedures.
