1986 Ford L8000 Service and Repair Manual
This factory service and repair manual for the 1986 Ford L8000 serves both medium-conventional body styles offered that year, the tractor truck and the straight truck, in Base trim with the 10.4L V8 diesel (636 cu in) as the only engine. One engine across two chassis keeps the manual's procedures, specifications and torque values to a single engine section, while the wiring diagrams and diagnostics take in the tractor and straight-truck versions. A shop running either type of L8000 works from the same diesel V8 figures and the same chassis references.
