Known issues on the 1984 General. Federal records show nothing against the 1984 General, neither a recall nor an owner complaint at NHTSA. The manual's role is the ordinary one for a class 8 conventional: engine specifications and service procedures for each diesel listed, including the turbocharged 14.0L and 14.6L inline-sixes, torque values for frame, axle and driveline fasteners, wiring diagrams for the cab and chassis circuits, and diagnostics arranged so a fault on a tractor is traced the same way as one on a straight truck.
