1986 Ford F-800 Service and Repair Manual
This factory service and repair manual for the 1986 Ford F-800 lists five engines for the medium conventional tractor truck and straight truck, both in a lone Base trim. Three of them are diesels: the 7.8L inline-six with a turbocharger, and the 8.2L V8 in both turbocharged and naturally aspirated versions. The other two, the 6.1L V8 and the OHV 7.0L V8, are naturally aspirated and run on gasoline or LPG (propane). An inline-six sitting beside V8s means the procedures, specifications, torque values, wiring diagrams and diagnostics have to be engine-specific, and they are.
