1989 Ford F-800 Service and Repair Manual
This factory service and repair manual for the 1989 Ford F-800 covers the medium conventional chassis as a tractor truck and as a straight truck, one Base trim in each case, with four engines. On the diesel side are two turbocharged inline-sixes, 6.6L and 7.8L. On the gasoline side are two naturally aspirated V8s, a 6.1L and an OHV 7.0L that can also run on LPG (propane). The inline-six and V8 layouts differ throughout their service routines, so the procedures, specifications, torque values, wiring diagrams and diagnostics are written out separately for all four.
