- The problem
- Mack is recalling 10,300 model year 2004 and 2005 cl, cv, dm, le, and rb and model year 2004 rd heavy trucks manufactured from october 1, 2003 through september 30, 2004, equipped with axle beams manufactured by bharat forge. The axle beam may have transverse shear lines on the bottom of the axle from the trimming process.
- The risk
- These lines, if present, can promote initiation of cracks, which over time may possibly lead to axle beam failure and a vehicle crash can occur.
- The fix
- Mack will notify owners, inspect and replace any affected axle beams free of charge. The safety recall began on august 14, 2009. Owners may contact mack at 1-800-866-1177.
- 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 problem
- On certain heavy duty class 8 trucks equipped with holland air suspension systems, a transverse beam casting may fracture under normal loads. If a casting breaks when the vehicle is traveling on a roadway there is the potential for pieces of the casting to become projectiles and the suspension's transverse beam may drop down low enough to contact the road surface.
- The risk
- This will cause sparks that could potentially ignite and cause a fire.
- The fix
- Dealers will inspect and replace the defective transverse beam assemblies. The recall began on august 19, 2005. Owners may contact mack trucks at 610-709-2131.
- The problem
- On certain heavy-duty, class 8 trucks, the lower and upper steering shaft pinch bolts were improperly tightened.
- The risk
- As a result of this condition, the steering shaft could possibly come loose which could lead to a sudden loss of vehicle control, which could result in a crash.
- The fix
- Dealers will inspect the torque at the suspect joints, and correct if necessary free of charge. The recall began on may 5, 2005. Owners may contact mack at 1-610-709-2131.
- The problem
- Certain trucks fail to comply with the requirements of federal motor vehicle safety standard no. 121, "Air brake systems." The front brake chamber on some 18,000 lb. And 20,000 lb front axle assemblies is too small to meet stopping distance requirements.
- The risk
- This could cause the stopping distance to be increased, which could result in a crash.
- The fix
- Dealers will replace the front brake chambers. The recall began april 21, 2004. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact mack at 1-610-709-3337.
