Mack Ch 2003

• Recall 72751 [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 34673 [USA]: This could cause ice buildup on the discharge side of the primary and secondary pressure system allowing the relief system to freeze and become blocked resulting in over pressurization of the lng tanks creating the risk of catastrophic tank rupture which could cause serious injury or death.
  On certain chassis built with lng engines, the nexgen lng tank's primary and secondary relief valves could fail to open and relieve tank pressure.
  dealers will retrofit the lng tanks with a new primary relief valve pipe away tube and a new ventilated shroud. The recall began april 6, 2004.

• Recall 2007278 [Canada]: Brakes
  On certain trucks, the engine configuration makes servicing fuel injection lines difficult when using traditional tools. It is possible for fuel leaks to develop following recall campaign 2006258 (mack sC0317) or when line removal is required to gain access to other engine components. Underhood fuel leakage could result in a vehicle fire. Correction: dealers will install an updated fuel injection line that offers better clamping surface when torqued. This will be done using specially designed tools to ensure correct torque is applied.

• Recall 2004341 [Canada]: Steering
  On certain vehicles, the bolts that mount the steering gear to the frame can fail due to bolt quality issues which cause variation in the torque-tension relationship for the joint. This results in an inconsistent clamp load, which can cause the bolt to be either over-stretched (at or above yield strength) or under-stretched when torqued to specification. Failure of two of the three bolts could result in loss of steering control. Correction: dealers will replace the mounting bolts.
