Recall 07V-497: 2006–2008 Mack CHN, 2006–2008 Mack CL and 6 more
MACK TRUCKS, INC recall for trailer hitches, reported to NHTSA on Oct 23, 2007, covering about 950 vehicles.
The problem
On certain trucks equipped with a saf holland simplex fifth wheel, the lever arm pivot bolt may have been over tightened. An over tightened pivot bolt can distort the pivot bolt spacer sleeve, which may prevent the fifth wheel latch jaw from closing and latching securely around the trailer king pin.
The risk
There is a possibility that the pivot bolt can become loose without the driver's knowledge. When this occurs, the driver could drive away and the trailer could become disengaged, increasing the risk of a crash.
The fix
Dealers will replace the pivot bolt and sleeve with a hex head shoulder bolt and washer free of charge. The recall began on january 28, 2008. Owners may contact mack trucks at 1-800-528-6586.
