Technical service bulletins and other communications the manufacturer sent dealers about this vehicle. Ask a dealer for the full document by its number.

• 3055700Unknown

• 51861Fd 1060 engines - new design starter motor to alleviate hard start/no start concerns in cold ambients.
• 51417Suspension - noise from front spring rear hanger - revised rear spring hanger insulator pad - vehicles equipped with 6000, 7000 or 9000 lb axles built through 10/1/97.
• 50440Vehicles may exhibit an exhaust leak &/or noise due to warped exhaust manifolds.
• 50356Information on aode/4r7w transmission main control & case replacement.
• 46478The use of petroleum-based grease as a lubricant in servicing disc brakes IS no longer acceptable because it may be incompatible with the rubber material used in the disc brake system. If petroleum-based grease IS used to lubricate any part of the disc brake system, it could cause rubber parts to swell if lubricant contacts the rubber material.
• 46477The engine coolant temp gauge may read on the cold side of the normal range, or may stay below normal even though the engine IS at its proper operating temp on some vehicles. This IS caused by the coolant temp sending unit not being positioned in the main stream of coolant flow. Install a new temp sender fitting.
• 46476Hard starting or a no start concern may occur on some vehicles. This may be due to diesel fuel draining out of the fuel injection system back into the fuel tank. This condition causes the injection system to lose its prime which leads to longer starter engagement times for engine shutdown period. Install a diesel fuel check valve (f5hz-9285-aa) on the fuel return line at the rear of the engine.
• 46446On f/b series w/ fd 1060 engine there may be a concern regarding insuffi- cient in-cab heat. To resolve this, the current thermostat can be replaced with a new low leak thermostat. The needed parts are available from cummis engine. Refer to tsb 95-20-12.
