1990 Ford F-53 Motorhome Chassis Service and Repair Manual
This factory service and repair manual for the 1990 Ford F-53 Motorhome Chassis covers a single trim, Custom, on the stripped motorhome chassis, and a single engine, the 7.5L V8 with overhead valves, natural aspiration and 460 cubic inches of displacement on gasoline. With only one trim and one engine in the lineup this year, the procedures, specifications, torque values, wiring diagrams and diagnostics can be followed without cross-checking option tables, which suits a chassis that spends its life under a coach body built by someone else.

Known issues on the 1990 F-53 Motorhome Chassis. One recall is on federal record for the 1990 chassis: brake lines in the engine compartment were routed too close to the left exhaust manifold, letting the brake fluid overheat and lose viscosity, with loss of braking or longer stopping distances as the consequence. Owners have logged three complaints with NHTSA, two on the service brakes and one on the steering. The brake hydraulic system is therefore the area to check first, and the manual's procedures, specifications and torque values for the brake lines and steering gear on the 7.5L V8 chassis address exactly those parts.
BRAKE LINES IN THE ENGINE COMPARTMENT ARE ROUTED TOO NEAR THE LEFT EXHAUST MANIFOLD, CAUSING THE BRAKE FLUID TO OVERHEAT.
CONSUMER WAS COMING DOWN I 65 IN IDIANA . TURNED RIGHT INTO A REST AREA. THEN HAD TO MAKE A LEFT, AND MOTORHOME WOULD NOT TURN LEFT, AND STEERING WAS STUCK. CONSUMER SAYD IT WAS THE STEERING STABLIZER
THE DISC BRAKES ON ALL FOUR WHEELS FAILED TO RELEASE WHEN BRAKES WERE APPLIED. THE OUTSIDE BRAKE PADS RUBBED AGAINST ROTORS. THIS CAUSED ROTORS TO OVERHEAT. CAN HAVE IT REPAIRED, BUT WEEK LATER PROBLE
Showing the 2 most serious of 3 complaints filed with NHTSA.
