1984 Ford LN8000 Service and Repair Manual
This factory service and repair manual for the 1984 Ford LN8000 documents a short-conventional tractor and straight truck, in Base trim, with two versions of the 10.4L V8 diesel (636 cu in), one turbocharged and one naturally aspirated. Shared displacement does not mean shared specifications, so the manual keeps the two apart in its procedures, specifications and torque values while its wiring diagrams and diagnostics cover both body configurations.

Known issues on the 1984 LN8000. The same 10.4L V8 diesel appears twice, once naturally aspirated and once turbocharged, which is the whole of the engine choice and the main division inside the manual: intake, boost control and charge-air work apply to one version only, while short-block specifications and torque values are common to both. Body coverage runs to a short-conventional tractor as well as a straight truck, so driveline, frame and air routing differ by configuration. NHTSA lists nothing against the year.
