Service Brakes, Air
- Defect, in the NHTSA record
Kenworth 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, in the NHTSA record
Cracking can cause a complete fracture of the cam tube, which could increase stopping distance and decrease parking brake hold capability.
- Remedy, in the NHTSA record
Dealers 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.

Service Brakes, Air / Disc
- Defect, in the NHTSA record
Paccar is recalling 86 my 2009 kenworth t660, t800, w900, and peterbilt 386, 365, and 388 trucks equipped with bendix front air disc brakes. The size 14 service chamber of certain front air disc brakes may have been contaminated with grease between the piston head/plate and the diaphragm. When braking pressure is applied, the grease may allow the piston head/plate to slip off center and catch on the reducing ring of the size 14 service chamber.
- Consequence, in the NHTSA record
The catching of the piston head/plate on the reducing ring may lock up the corresponding front air disc brake which may impact the operator's ability to steer or control the vehicle.
- Remedy, in the NHTSA record
Dealers will replace both front air disc brakes size 14 service chambers free of charge. The recall began on august 27, 2008. Owners may contact kenworth at 1-425-828-5440 and peterbilt at 1-940-591-4196.

Suspension
- Defect, in the NHTSA record
Kenworth is recalling 1,189 my 2009 t2000, t600, t660, t800 and w900 trucks. The axle u-bolts attaching the axle to the drive beam on certain ag380 rear suspensions may have received insufficient fastener torque during the installation process.
- Consequence, in the NHTSA record
The insufficient torque may allow the axle u-bolt to loosen if undetected, could impact long term suspension performance and increase the risk of a crash.
- Remedy, in the NHTSA record
Dealers will have the axle u-bolt on the affected chassis re-torqued to factory specifications free of charge. The recall began on august 12, 2008. Owners may contact kenworth at 425-828-5440.
Report filed by PACCAR INCORPORATED. Manufacturer campaign number 08KW9. Owner notification date in the NHTSA record: .
08V280000Received . 62 units.
Latches/Locks/Linkages / Hood / Latch
- Defect, in the NHTSA record
Paccar is recalling 62 my 2009 kenworth t660 trucks. The 90 degree standoff mounted on the front bumper support may come into contact with the hood strut, which may result in a non-operational hood safety latch. The safety latch prevents the hood from closing.
- Consequence, in the NHTSA record
A non-operational safety latch may not be detected by a driver or mechanic and could increase the risk of personal injury or vehicle damage.
- Remedy, in the NHTSA record
Dealers will relocate the 90 degree standoff and reroute the headlight harness away from the hood strut in order to provide the clearance needed. The recall began on july 21, 2008. Owners may contact kenworth at 1-425-828-5440.
Report filed by PACCAR INCORPORATED. Manufacturer campaign number 08KW8. Owner notification date in the NHTSA record: .
08V128000Received . 1,043 units.
Parking Brake / Conventional / Air
- Defect, in the NHTSA record
Paccar is recalling 1,043 my 2008-2009 kenworth c500, t2000,t660, t800 and w900 trucks equipped with bendix mv-3 dash control valves. The molded valve body has an incorrect core pin in the injection mold causing the valve body to be oversized in the double check valve area. This condition can allow the rubber double check valve to become lodged in the body opening under certain circumstances.
- Consequence, in the NHTSA record
If the double check valve becomes lodged, in the event of a primary reservoir failure, air pressure can leak past the lodged double check valve thereby depleting the secondary reservoir, causing reduced ability for modulating the service emergency brakes. In such an event, the operator should observe an air leak, indications of low air pressure via the primary and secondary air gauges, and audible and visual low air pressure warning alarms. A vehicle crash is possible if these warnings are not heeded.
- Remedy, in the NHTSA record
Dealers will replace the bendix mv-3 dash control valves free of charge. The recall began on april 14, 2008. Owners may contact kenworth at 1-425-828-4196.
