Known issues on the 1984 Brigadier. No recall touches this truck, and NHTSA carries no owner complaints for it. The manual therefore stands on what it documents. Seven diesel engines are covered with procedures, specifications, torque values, wiring diagrams and diagnostics, and the short conventional chassis is covered to the same standard, from the frame rails and driveline through the air and hydraulic systems to the wiring that runs the length of the truck.
