07V090000 on 03/08/2007
Component:
Service brakes, air
Manufactured:
05/22/2005 - 01/13/2007
Affected:
65
Defect:
Certain trucks fail to comply with the brake timing regulatory requirements of federal motor vehicle safety standard no. 121, "air brake systems." the brake valve was moved to the opposite rail, increasing the length of the air line, which in turn increased the wheelbase requiring a dual relay valve system. the vehicles were manufactured with a single valve system.
Consequence:
If stopping distance was limited, a vehicle crash could result.
Correction:
Dealers will convert the single relay valve to a dual relay valve system free of charge. the recall began on may 21, 2007. owners may contact kenworth at 425-828-5440.

Defect:
On certain trucks, the rear hood mounting brackets can contact the front axle brake chamber during full axle articulation.
Consequence:

Correction:
Dealers will inspect the brake chamber and surrounding components for any damage and modify the rear hood support bracket to eliminate the potential for interference. if any brake components is damaged, the dealer will be instructed to replace the components free of charge. the recall began on may 14, 2007. owners may contact kenworth at 425-828-5440.

Campaign:
08V190000 on 04/24/2008
Component:
Trailer hitches:fifth wheel assembly
Affected:
3,573
Defect:
Paccar is recalling 3,573 my 2007 kenworth c500, t800, t600, t2000, and w900 chassis built with phillips qcs ii trailer cable connection and trailer cable mounting bracket with 'u-shaped' cut out. certain trailer cable mounting brackets have a 'u-shaped' cut out that only partially supports the trailer cable connection. partial support of the cable connection may allow the molded boot and electrical ground pin to partially or completely pull away from the 7-way socket. partial or complete detachment of the cable connection can cause reduced water resistance and potential loss of electrical ground. there is also a possibility the trailer lights may fail to illuminate without the operator's knowledge.
Consequence:
If this condition were to occur, other motorists may not be warned of the tractor/trailer movements, increasing the risk of a crash.
Correction:
Dealers will install a reinforcement bracket between the flexible back of the qcs ii molded boot and the frame bracket, and reattach the supporting bolts. the recall began on may may 30, 2008. owners may contact kenworth at 1-425-828-5440.

Consequence:
This could result in a fire.
Correction:
Caterpillar is handling the owner notification and remedy for this campaign. please see caterpillar's defect report 11e-006. caterpillar will replace the single piece combustion tube with a thick wall combustion tube which will not allow the heat to break through. this service will be performed free of charge. due to a parts supply issue, owners will be notified by the end of april 2011 about the safety defect, and will then be notified again once the free remedy is available, currently estimated to be around late july 2011. owners may contact caterpillar toll-free at 1-800-447-4986.
