1988 Ford LN9000 Service and Repair Manual
This factory service and repair manual for the 1988 Ford LN9000 covers a short-conventional Ford heavy truck built as either a tractor or a straight truck, with three turbocharged inline-six diesels to choose between: 10.0L (611 cu in), 14.0L (855 cu in) and 14.6L (893 cu in). Only the Base trim is listed. Because all three engines share the same turbocharged inline-six layout, the manual's specifications and torque values are what separate them, and the procedures are written to be followed engine by engine.
