Defect SummaryKenworth is recalling 3,423 my 2004-2009 t2000, t800,t600, w900 and t660 vehicles. increased brake excitation in a certain vehicle configuration which includes bendix drum brakes, wide base low profile single tires, and an ag400 or ag460 rear suspension, due to its unique brake clocking and cam tube length, can cause fatigue and cracking to brake assembly components.
Consequence SummaryCracking can cause a complete fracture of the cam tube, which could increase stopping distance and decrease parking brake hold capability.
Corrective SummaryDealers will inspect the rear axle brakes assembly, replace cracked rear axle brakes assembly components where required, and install cam tube support brackets on all rear axle wheel ends free of charge. the recall is expected to begin or before july 25, 2009. owner may contact kenworth at 1-425-828-5440.

Defect SummaryCertain 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 SummaryIf stopping distance was limited, a vehicle crash could result.
Corrective SummaryDealers 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 SummaryPaccar is recalling 140 my 2005, 2007-2009 t800, w900, and t660 trucks. the caliper mounting fasteners attaching the air disc brake caliper assembly to the torque plate may have received insufficient torque during the installation process. the insufficient torque may allow the air disc brake caliper assembly to become loose and possibly separate from the vehicle.
Consequence SummaryThis could result in reduced braking capacity and also a road debris hazard, increasing the risk of a crash.
Corrective SummaryDealers will inspect air disc brake caliper assemblies and replace the caliper mounting fasteners and torque properly. this service will be performed free of charge. the manufacturer has not yet provided an owner notification schedule. owners may contact kenworth at 1-425-828-5440.

Defect SummaryPaccar is recalling 130 my 2005-2007 kenworth c500, t800, w900, and peterbilt models 357 and 379 tractor trailers equipped with fabco slack adjusters on sisu axles. the slack adjusters may fail as a result of a fatigue crack rendering the slack adjuster inoperative. this could reduce braking effectiveness.
Consequence SummaryReduction in braking capacity could increase the risk of a crash.
Corrective SummaryDealers will inspect and replace the slack adjusters free of charge. the recall began on march 21, 2008. owners may contact kenworth at 1-425-828-5440 and peterbilt at 1-940-591-4196.

 On june 23, 2009 paccar notified odi that 3,423 kenworth t2000, t800, t600, w900, and t660 trucks, model years 2004 - 2009, equipped with bendix brakes, wide base low profile tires and airglide (ag) 400/460 rear suspensions are being recalled.certain of these vehicles have experienced fatigue cracks in the brake cam tube mounting or air chamber mounting flanges bracket adjacent to the attachment welds. if left unrepaired, the cracks can cause a complete fracture of the cam tube, which could disable the affected brake and risk increasing vehicle stopping distances under high pressure brake applications and decrease parking brake capability.this configuration has experienced failures at a higher rate than similar vehicles with other types of suspensions and brake installation clocking. paccar will also send an owner notification letter to owners of vehicles equipped with suspensions other than the ag 400/460, which will prescribe a periodic inspection of the components and if a crack is discovered, offer the owners the opportunity for a free repair.this policy will be in effect until july 15, 2014. copies of the recall and the owner notification are attached.
