1987 Ford LTS8000 Service and Repair Manual
This factory service and repair manual for the 1987 Ford LTS8000 covers two straight truck layouts, a low tilt cab and a medium conventional, and two diesel engines beneath them. The turbocharged 7.8L inline-six of 473 cubic inches is the smaller of the pair; the 10.4L V8 at 636 cubic inches is the larger and runs without a turbocharger. Base trim is the only listing, so the branching here is by engine and cab rather than by equipment level, and the specifications, torque values, wiring diagrams and diagnostics follow those two divisions.

Known issues on the 1987 LTS8000. The 1987 LTS8000 carries no recalls on the federal record and no owner complaints at NHTSA. With nothing on the books to correct, the manual functions as a reference for two very different diesels: turbocharger and charge-air service on the 7.8L inline-six, straightforward injection and cooling work on the 10.4L V8, torque values for both, and wiring diagrams to read alongside the diagnostics.
