1989 Ford LTL9000 Service and Repair Manual
This factory service and repair manual for the 1989 Ford LTL9000 pares the chassis list down to the long-conventional straight truck and the long-conventional tractor truck, both Base trim, and keeps the three turbocharged diesel inline-sixes: the 10.0L (611 cu in), the 14.6L (893 cu in) and the 14.0L (855 cu in). With the low-tilt cab gone from the list, the 1989 procedures, specifications, torque values, wiring diagrams and diagnostics divide simply between the three engines and the tractor and straight-truck configurations of one conventional chassis.

Known issues on the 1989 LTL9000.
