Motor Coach Industries due to insufficient clamping force of the cylinder lock plate, it may move from its normal set position, which in turn could result in the tag axle not automatically locking, or locking with the wheels not in a straight ahead position.
The short version
MOTOR COACH INDUSTRIES, INC reported a problem with the linkages tie rod assembly. Here is what owners need to know.
MCI IS RECALLING MODEL YEAR 2009 D4500/4505 COACHES EQUIPPED WITH THE MERITOR FH 946 14,000 LB RATED STEERABLE TAG AXLE. DUE TO INSUFFICIENT CLAMPING FORCE OF THE CYLINDER LOCK PLATE, IT MAY MOVE FROM ITS NORMAL SET POSITION, WHICH IN TURN COULD RESULT IN THE TAG AXLE NOT AUTOMATICALLY LOCKING, OR LOCKING WITH THE WHEELS NOT IN A STRAIGHT AHEAD POSITION.
IF THE TAG AXLE DOES NOT LOCK ABOVE 20 MPH, THERE IS A LOSS OF LATERAL FORCE CONTROL OF THE TAG AXLE THAT CAN AFFECT THE STEERING OF THE VEHICLE. ALSO DURING A TURN THE REAR OF THE VEHICLE WILL SWING FURTHER OUT IN THE OPPOSITE DIRECTION OF THE TURN AND COULD RESULT IN THE COACH STRIKING ANOTHER VEHICLE INCREASING THE RISK OF A CRASH.
DEALERS WILL PROVIDE REPLACEMENT CLAMPS THAT DO NOT HAVE PAINT ON THE CLAMPING SURFACES, free of charge.
