Service brakes, air:supply:check valve
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.
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.
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.
Suspension
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.
Risk: This will cause sparks that could potentially ignite and cause a fire.
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.
Steering
Problem: On certain heavy-duty, class 8 trucks, the lower and upper steering shaft pinch bolts were improperly tightened.
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.
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.
Service brakes, air:disc:chamber
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.
Risk: This could cause the stopping distance to be increased, which could result in a crash.
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.
