Mack Chn 2007

• Recall 71547 [USA]: 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.
  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.
  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.

• Recall 72752 [USA]: 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.
  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.
  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.

• Recall 31985 [USA]: 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.
  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.
  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.

• Recall 2007264 [Canada]: Brakes
  On certain vehicles, the internal rubber check valve inside the bendix sr-7 spring brake modulating valve can become deformed over time. The effect of this defect is intermittent and presents a potential delay or failure in applying the parking brakes; potentially resulting in a vehicle roll away.

• Recall 2007265 [Canada]: Brakes
  On certain school and transit buses, the parker single check valve (scv) that connects with the supply port of the bendix sr-7 spring brake modulating valve may become excessively worn and eventually break apart. Pieces of the parker scv can become lodge inside the sr-7 valve, possibly causing either leakage out of the sr-7 valve or preventing air from properly exhausting from the sr-7 valve. This condition can cause a delay in the application of the parking brakes, the spring brakes not fully releasing or loss of isolation between the primary and secondary circuits. These conditions can occur without warning, leading to unintended vehicle rollaway, brake drag, or in case of loss of primary circuit, inability to modulate the spring brakes. An unattended roll away vehicle could strike a bystander or cause property damage. Correction: dealers will replace the single check valve (scv).

2007 mack truck chn 613, 427 aset ac engine failure due to oil pump drive gear spinning loose on auxiliary shaft. When the vehicle began traveling down hill, the oil pump drive gear failed causing an immediate loss of oil pressure. The engine became a critical instrument in controlling the vehicle's down hill speed particularly the engine brake feature aka the "jake brake". The engine brake uses engine oil flow to operate. Since there was no more oil flow, the engine brake was rendered unusable. At this point, the choice was to continue down hill and rely solely on the vehicle brakes to control the vehicle speed, or continue to use the engine without the added braking power of the engine brake knowing that the engine would be destroyed. The driver chose to destroy the engine and not risk his life or the lives of others. The dealer refused to repair the vehicle under warranty because the eecm indicated the engine's maximum allowed speed was exceeded. Further investigation revealed the problem is inherent to all aset engines because the oil pump gear helix was changed for the new design engine. The auxiliary shaft direction of rotation was reversed and the direction of thrust on the drive gear forces the drive gear away from the rear bearing journal which it is nested against. Older engine design had the direction of thrust toward the bearing journal which held the gear in place. Any condition, (like an engine overspeed) that would increase oil pressure could dislodge the gear. According to the dealer, an engine overspeed condition can only occur while going down hill and using the engine to control vehicle speed. If the hill would have been higher, the engine may not have been able to continue to slow the vehicle and a crash would most likely have occurred. This happened in southeast louisiana where high hills are non existent. Had this happened in a mountainous area, it could have been disastrous. Mack trucks refuses to discuss this any further. *tr
