2008 MACK CXN Recalls (5)

Campaign:
07V361000 on 08/15/2007
Component:
Service brakes, air:supply:check valve
Manufactured:
01/01/2004 - 07/25/2007
Affected:
21,847
Defect:
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:
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.
Correction:
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.

Defect:
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.
Consequence:
This could delay or failure in applying the parking brakes which could result in a vehicle roll away, increasing the risk of a crash.

01/08/2006 - 06/28/2007
Affected:

Defect:
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.
