07V497000Received 23 Oct 2007. 950 units.
Trailer Hitches / Fifth Wheel Assembly
Defect, in the NHTSA record
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.
Consequence, in the NHTSA record
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.
Remedy, in the NHTSA record
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.
Report filed by MACK TRUCKS, INC. Manufacturer campaign number SC0331. Owner notification date in the NHTSA record: 28 Jan 2008.
07V401000Received 5 Sep 2007. 35,649 units.
Fuel System, Diesel
Defect, in the NHTSA record
On certain trucks equipped with aset AC model engines, the engine as configured with an external exhaust gas recirculation system makes servicing the fuel injection lines difficult when using traditional tools. Therefore, it is possible for fuel leaks to develop when removing and installing the fuel injection lines.
Consequence, in the NHTSA record
A leak in the fuel injection line may spray fuel on the hot surfaces of the exhaust gas recirculation system, which could result in an engine fire.
Remedy, in the NHTSA record
Dealers will replace the fuel injection lines free of charge. Note: this recall supersedes a previous campaign conducted in 2006 (please see 06v392). The recall began on september 11, 2007, with subsequent mailings every six weeks until april 2008. Owners may contact mack at 800-528-6586.
Report filed by MACK TRUCKS, INC. Manufacturer campaign number SC0324. Owner notification date in the NHTSA record: 11 Sep 2007.
07V361000Received 15 Aug 2007. 21,847 units.
Service Brakes, Air / Supply / Check Valve
Defect, in the NHTSA record
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.
Consequence, in the NHTSA record
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.
Remedy, in the NHTSA record
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.

Parking Brake
Defect, in the NHTSA record
On certain trucks equipped with bendix sr-7 spring brake modulating valves, the internal rubber check valve may leak causing a delay in the application of the spring brakes to park the vehicle after the operator pulls the dash valve button.
