1988 Ford FT900 Service and Repair Manual
This factory service and repair manual for the 1988 Ford FT900 narrows to a single engine, the turbocharged 7.8L inline-six diesel of 473 cubic inches, fitted to both the tractor truck and the straight truck versions of the medium conventional chassis. One Base trim covers them. With only one diesel in play, the engine chapters go deep on that unit, covering injection timing, turbocharger service and cooling specifications, while the chassis and brake sections carry the differences between hauling a trailer and carrying a mounted body.

Known issues on the 1988 FT900. No recalls sit on the federal record for this truck, and NHTSA logs no owner complaints against it. That puts the weight on routine service work, which is where the manual does its job: the turbocharged 7.8L inline-six with its fuel, air and cooling systems, the driveline behind it, brake procedures for both the tractor and straight truck layouts, and the cab and chassis wiring diagrams that go with a medium conventional.
