1987 Ford LN8000 Service and Repair Manual
This factory service and repair manual for the 1987 Ford LN8000 covers three diesel engines in a short-conventional tractor or straight truck with Base as the only trim: the turbocharged 7.8L inline-six (473 cu in) and the 10.4L V8 (636 cu in) in turbocharged and naturally aspirated versions.
