1984 Ford LN9000 Service and Repair Manual
This factory service and repair manual for the 1984 Ford LN9000 is written for five diesel engines across two body styles. Three of the engines are turbocharged inline-sixes, the 10.0L (611 cu in), the 14.0L (855 cu in) and the 14.6L (893 cu in); the other two are the 9.0L V6 (552 cu in) and the 7.0L inline-six (426 cu in). The chassis is either a short-conventional tractor truck or a short-conventional straight truck, and only one trim, Base, is listed, so the engine choice is the main variable a technician has to pin down before following a procedure.
