1986 Ford LT9000 Service and Repair Manual
This factory service and repair manual for the 1986 Ford LT9000 covers a four-engine year, with the turbocharged 10.0L inline-six (611 cu in), the turbocharged 14.6L inline-six (893 cu in), the turbocharged 14.0L inline-six (855 cu in) and the 9.0L V6 (552 cu in) as the diesels on offer. Body styles return to two, the medium-conventional tractor truck and the medium-conventional straight truck, and Base is again the only trim. That narrows the 1986 manual's procedures, specifications, torque values, wiring diagrams and diagnostics to three turbocharged inline-sixes and one V6 across two chassis types.

Known issues on the 1986 LT9000. NHTSA carries one recall for the 1986 LT9000, and it is about labeling: hand throttle controls were not identified on the control knob or on the instrument panel, which the federal standard on controls and displays requires. No owner complaints are logged with NHTSA for this year. Any work that follows from the recall lands on the throttle and instrument panel, and the manual's procedures, specifications, wiring diagrams and diagnostics cover those along with torque values for the four diesels and the two chassis.
HAND THROTTLE CONTROLS WERE NOT IDENTIFIED EITHER ON THE CONTROL KNOB OR ON THE INSTRUMENT PANEL AS REQUIRED BY FMVSS 101.
