- 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 problem
- On certain trucks equipped with parker single check valves (scv) provided by bendix. The defect exists in the parker scv that connects with the supply port of the sr-7 spring brake modulating valve. After prolonged use of the parker scv, the valve body retainer may become excessively worn and eventually break apart. Pieces of the parker scv can become lodged inside the sr-7 spring brake modulating valve, potentially causing either leakage out of the sr-7 valve or preventing air from properly exhausting from the sr-7 valve.
- The risk
- This condition can cause a delay in the application of the spring brakes to park the vehicle after the operator pulls the dash valve button. These conditions can occur without warning, leading to unintended vehicle rollaway, brake drag, or in the case of loss of primary circuit, inability to modulate the spring brakes.
- The fix
- Mack is working with bendix to replace the parker single check valve. The recall began on january 9, 2008. Owners may contact bendix at 1-440-329-9000 or mack at 1-800-528-6586.

- The fix
- Mack is working with bendix to repair these vehicles (please see 07e037). Bendix will install a check valve repair kit for the affected sr-7 spring brake modulating valve free of charge. The recall began on january 10, 2008. Owners may contact bendix at 1-440-329-9000 or mack at 1-800-528-6586.
