Mack Trucks, Inc.
The problem
THE INVOLVED TRUCKS HAVE PITMAN ARMS WITH TIMING MARKS AND SERRATIONS LOCATED 8 DEGREES OUT OF PROPER ALIGNMENT. WHEN THE CHASSIS IS RAISED TO THE MAXIMUM CONDITION WITH THE WHEELS SUSPENDED OR DROPPED INTO A DEEP HOLE, THE PITMAN ARM AND DRAG LINK CAN GO INTO TOGGLE POSITION.
What owners should do
UPON INSPECTION, ALL DEFECTIVE PITMAN ARMS WILL BE REPLACED WITH PROPERLY TIMED ARMS.
