1984 Ford LT8000 Service and Repair Manual
This factory service and repair manual for the 1984 Ford LT8000 pairs one engine with two configurations. The 10.4L V8 diesel of 636 cu in is the only unit listed, and it powers both a medium-conventional tractor truck and a medium-conventional straight truck, each in Base trim. Since the trucks share their drivetrain, the engine specifications, torque values and diagnostics are written once and apply to either, and the brake, chassis and electrical sections, wiring diagrams included, follow the same pattern.

Known issues on the 1984 LT8000. There is no recall on federal record for this model year and no owner complaint logged with NHTSA.
