Known issues on the 1998 FT900. Neither a recall nor an owner complaint is on the federal record with NHTSA for this truck. Without campaign work to plan around, the manual's value lies in the everyday jobs: setting injection and valve specifications on the 8.3L inline-six, servicing the turbocharger and cooling system, overhauling the clutch and transmission, adjusting the brakes, and tracing cab and chassis circuits with the wiring diagrams supplied for the medium conventional straight truck.
