NHTSA Campaign 83V101000

STEERING:GEAR BOX (OTHER THAN RACK AND PINION)

Issued by MACK TRUCKS, INCORPORATED · Reported Sep 27, 1983 · 1,486 vehicles affected

What's wrong

BOLTED INSTALLATION OF THE STEERING GEAR HOUSING HAS A TENDENCY TO LOOSEN IN SERVICE. THIS IS DUE TO A BACKWARD INSTALLATION OF THE LOCKWASHERS, WHICH ARE BELLVILLE TYPE, AND A RESULTANT INCORRECT TORQUE ON THE BOLTS.

Remedy

ALL RECALLED VEHICLES WILL HAVE BELLVILLE TYPE LOCKWASHERS AT STEERING GEAR HOUSING ATTACH POINTS REPLACED WITH STANDARD SPLIT-TYPE LOCKWASHERS.
