1998 Ford L9511 Service and Repair Manual
This factory service and repair manual for the 1998 Ford L9511 covers five diesel engines in a medium-conventional tractor or straight truck with a single Base trim. Alongside the 10.5L six-cylinder (638 cu in) are four turbocharged engines: the 12.0L six-cylinder (732 cu in) and inline-sixes at 10.8L (661 cu in), 14.0L (855 cu in) and 10.3L (629 cu in). The manual pairs procedures, specifications, torque values, wiring diagrams and diagnostics with each engine, so the 14.0L and the 10.3L are treated as the distinct units they are.
