All Mack F recalls (23)

Every NHTSA safety campaign that lists a Mack F, most recent first, with the model years each one covers.

1. Leaf spring assembly (suspension)

   NHTSA 79V171000 Reported July 12, 1979 1,706 vehicles potentially affected MACK TRUCKS, INCORPORATED

   The spring seat plate, located between the axle housing and the suspension springs, may deform due to spring bending. As a result, the clamping force in the assembly may be reduced. Loss of clamping force could cause spring failure and the axle will dislocate. Also, the tire could come into contact with the spring.

   Remedy: The dealer will replace the existing spring seat with a newly fabricated seat which is welded to the housing. An improved spring clamping plate and new springs will also be installed without charge.

   Model years: 1979

2. Engine (engine and engine cooling)

   NHTSA 79V133000 Reported May 31, 1979 23,000 vehicles potentially affected MACK TRUCKS, INCORPORATED

   In the event of turbocharger compressor wheel failure, one or more of the four capscrews that hold the turbocharger together may be struck by parts of the compressor wheel, resulting in the capscrews being damaged. If these capscrews are damaged to the point that they allow the compressor back plate to dislocate from the turbocharger…

   Remedy: Dealer will install a shield for the heads of the four capscrews, along with stronger sae 8 grade 8 capscrews, if necessary, at no cost to owner.

   Model years: 1977, 1978, 1979

3. Hanger/bracket (suspension)

   NHTSA 79V018000 Reported January 12, 1979 17 vehicles potentially affected MACK TRUCKS, INCORPORATED

   The steel brackets on the suspension beam were found to be deficient due to excessive shrinkage and low mechanical properties. Failure of one or both of these brackets could cause a separation of the axle housing from the suspension.

   Remedy: The dealer will inspect and, if necessary, replace any suspect bogie spring insulator caps with new caps meeting the proper specifications at no cost to owner.

   Model years: 1978

4. Interconnecting assembly(wiring) (service brakes)

   NHTSA 78V210000 Reported October 3, 1978 19,370 vehicles potentially affected MACK TRUCKS, INCORPORATED

   Delays of up to about 2 seconds may exist in the brake application times to the brakes on the bogie axles in the presence of certain types of wheel speed sensor signal discontinuities or distortions that may occur as a result of sensor wire failure. This constitutes a non-compliance to federal motor vehicle safety standard no. 121, "air…

   Remedy: Dealer will install new wheel speed sensors that incorporate improved wiring and the present bogie anti-wheel lock system will be changed to an axle-to-axle system for improved reliability.

   Model years: 1977, 1978

5. Arm (steering)

   NHTSA 78V171000 Reported August 8, 1978 2,100 vehicles potentially affected MACK TRUCKS, INCORPORATED

   Deficiencies, in the form of forging laps, cracks and excessive decarburization during heat treatment, exist in the steering knuckles. Stresses imposed with integral hydraulic power steering may lead to a failure in the area of the steering arm attaching boss. This type of failure would cause loss of steering control.

   Remedy: Dealer will inspect and, if necessary, replace the left steering knuckle with an improved type of knuckle.

   Model years: 1971, 1972, 1973, 1974

6. Service brakes, air: control unit/module

   NHTSA 78V068000 Reported April 4, 1978 9,700 vehicles potentially affected MACK TRUCKS, INCORPORATED

   An axle "no brake" condition could result from an eaton controller internal electrical malfunction. This condition may cause the anti-wheel lock valve solenoid to be continuously energized and prevent the brakes from being applied on one of the axles. As a result, the anti-wheel lock warning lamp is not activated.

   Remedy: The dealer will inspect and, if necessary, replace the anti-wheel lock controller without charge to owner.

   Model years: 1974, 1975, 1976

7. Multiple axle (suspension)

   NHTSA 78V031000 Reported February 9, 1978 33,000 vehicles potentially affected MACK TRUCKS, INCORPORATED

   The tee bracket, which is mounted on the front axle of the bogie, may fail due to vibration brought on by road surface irregularities. Bracket failure would leave the tee bracket unsupported and cause broken hose connector fittings. This would result in automatic application of the spring emergency brakes.

   Remedy: The dealer will replace the defective bracket with a redesigned version.

   Model years: 1975, 1976, 1977, 1978

8. Hanger/bracket (suspension)

   NHTSA 77V205000 Reported November 21, 1977 7,400 vehicles potentially affected MACK TRUCKS, INCORPORATED

   A deficiency exists in the welds securing the rear spring insulator bracket to the axle housing. This is due to improper positioning of the weld, in relationship to the bracket and axle housing. Failure of the welds would cause separation of the spring insulator bracket and the axle housing, resulting in improper alignment of the…

   Remedy: Dealer will reweld the insulator spring bracket at no cost to owner.

   Model years: 1977

9. Fan (engine and engine cooling)

   NHTSA 77V173000 Reported October 12, 1977 48,000 vehicles potentially affected MACK TRUCKS, INCORPORATED

   The flex blade fans on the involved vehicles may develop cracks in the laminated stiffener as a result of fatigue during operation. If such a condition exists and the cracks go undetected, continued operation could cause pieces of the stiffener to break off.

   Remedy: Dealer will replace the original fan with a steel fixed blade fan, free of charge.

   Model years: 1972, 1973, 1974, 1975, 1976, 1977

10. Anchorage (seat belts)

    NHTSA 77V174000 Reported October 12, 1977 6,591 vehicles potentially affected MACK TRUCKS, INCORPORATED

    The involved vehicles do not conform to federal motor vehicle safety standard no. 209, "seatbelt assemblies". Although the seatbelts in question performed marginally with respect to the 5000 lb. Load requirement, additional testing confirmed that the anchor could fail, allowing either the anchor to slip over the hold-down nut or the…

    Remedy: Dealer will inspect and, if necessary, replace seat belt assemblies without charge to owner.

    Model years: 1977

11. Wheels

    NHTSA 77V096000 Reported June 17, 1977 825 vehicles potentially affected MACK TRUCKS, INCORPORATED

    The front wheel rim clamp studs, installed on the involved vehicles, may not have been manufactured correctly, causing a brittle condition in the thread root area. The studs could eventually crack and break when wheel nuts are tightened to specifications.

    Remedy: The dealer will replace all suspect front wheel studs, without charge to owner.

    Model years: 1977
