4. 11V127000Received 23 Feb 2011. 4,664 units.

   Fuel System, Other / Storage / Tank Assembly

   Defect, in the NHTSA record

   Paccar is recalling certain model year 2008-2012 kenworth t2000, t660, t700, t800, and w900, as well as model year 2009-2012 peterbilt 365, 367, 384, 386, 387, 388, 389, and 587 trucks equipped with paccar mx engines. The oil module centrifugal spinner filter cap in the paccar mx engine may become loose, possibly allowing the cap to come off and engine oil to partially discharge from the oil module onto exhaust components.

   Consequence, in the NHTSA record

   The discharge of engine oil onto exhaust components which are hot, such as when the engine is under significant load, may cause a fire.

   Remedy, in the NHTSA record

   Dealers will re-torque the oil module filter cap and install a secondary retention device on the secondary centrifugal spinner filter cap. This service will be performed free of charge. The safety recall is expected to begin during march 2011. Owners may contact kenworth at 1-425-828-5440 and peterbilt at 1-940-591-4196.

5. 10V535000Received 27 Oct 2010. 417 units.

   Service Brakes, Air / Disc / Caliper

   Defect, in the NHTSA record

   Paccar is recalling certain model year kenworth t660, t700, t800 and w900 vehicles manufactured from december 22, 2008, through august 2, 2010, and equipped with ag400l air disc brakes. The air disc brake caliper could be installed on the wrong side of the drive axle potentially causing interference with the suspension bracket and the rear suspension as the outermost brake pads wear and the floating caliper moves inboard.

   Consequence, in the NHTSA record

   As this interference gets larger, this could eventually lead to reduced braking performance, increasing the risk of a crash.

   Remedy, in the NHTSA record

   Dealers will verify the correct orientation of the brake caliper and perform the necessary repair free of charge. The safety recall began on november 24, 2010. Owners may contact kenworth at 425-828-5440.

   Report filed by PACCAR INCORPORATED. Manufacturer campaign number 10KWH. Owner notification date in the NHTSA record: 24 Nov 2010.

6. 10V308000Received 2 Jul 2010. 9,697 units.

   Steering / Column

   Defect, in the NHTSA record

   Paccar is recalling certain model year 2008-2010 trucks equipped with trw steering shafts. The circumferential weld around the steering shaft tube that welds the splined tube to the non-splined tube may be mislocated. Mislocation of the circumferential weld may allow the splined tube and non-splined tube to rotate relative to one another during a low speed, high torque turn, possibly resulting in a separation of the two tubes.

   Consequence, in the NHTSA record

   A separation of the splined and non-splined tubes would cause a loss of steering control and increase the risk of a vehicle crash.

   Remedy, in the NHTSA record

   Dealers will inspect the steering shaft using a weld placement gauge provided by trw. Any steering shaft found to have been welded improperly will be replaced free of charge. The safety recall began on july 30, 2010. Owners may contact kenworth at 425-828-5440 and peterbilt at 940-591-4196.

   Report filed by PACCAR INCORPORATED. Manufacturer campaign number 10KW-F & 0610-D. Owner notification date in the NHTSA record: 30 Jul 2010.

7. 09V415000Received 21 Oct 2009. 914 units.

   Power Train / Axle Assembly

   Defect, in the NHTSA record

   Kenworth is recalling model year 2009 through 2010 t2000, t800, t660 and w900 trucks manufactured between november 12, 2008 and september 30, 2009. The axle u-bolts attaching the axle to the suspension leaf spring on certain ag400l rear suspensions may have received insufficient fastener torque during the installation process. The insufficient torque may allow the axle u-bolt to become loose, which may cause vibration in the rear suspension.

   Consequence, in the NHTSA record

   If multiple fasteners were to become loose, the rear axle may shift relative to the rear suspension leaf spring, which can result in loss of control and a crash.

   Remedy, in the NHTSA record

   Dealers will inspect the axle u-bolts for visible defects, including bent and/or smashed threads and re-torque the axle u-bolts to factory specifications. The recall began on november 4, 2009. Owners may contact kenworth at 425-828-5440.

   Report filed by PACCAR INCORPORATED. Manufacturer campaign number 09KWA. Owner notification date in the NHTSA record: 4 Nov 2009.

8. 09V348000Received 3 Sep 2009. 135 units.

   Engine and Engine Cooling / Engine / Diesel

   Defect, in the NHTSA record

   Paccar is recalling model year 2008-2010 kenworth t300, t270, and t370, model year 2009-2010 t800 and peterbilt model year 2008-2010 335, 340, and 367 vehicles built on cummins' diesel engine. The vehicles may be designed with a hard wired, dash-mounted switch that enables the vehicle operator to inhibit aftertreatment diesel particulate filter regeneration in environments where the operator believes it may be unsafe for elevated exhaust temperatures. Due to an issue with the logic in the ecm software in these engines, the switch may not function correctly, leading the operator to believe that the switch is in "inhibit" mode when it is not.

   Consequence, in the NHTSA record

   This condition will permit hot exhaust gases to exit the vehicle tailpipe, increasing the risk of melting or burning of nearby surfaces, or a fire.

   Remedy, in the NHTSA record

   Paccar is working with cummins to repair the engines free of charge please see 09e-046. The safety recall began on october 1, 2009. Owners may contact cummins at 1-800-diesels (1-800-343-7357).

   Report filed by PACCAR INCORPORATED. Manufacturer campaign number 09KW9 & 909-D. Owner notification date in the NHTSA record: 1 Oct 2009.

9. 09V258000Received 8 Jul 2009. 2,096 units.

   Steering / Column

   Defect, in the NHTSA record

   Paccar is recalling 2,096 my 2009 kenworth and peterbilt vehicles equipped with trw steering shafts. Mislocation of a circumferential weld may allow the splined tube and non-splined tube to rotate relative to one another during a low speed, high torque turn, possibly resulting in a separation of the two tubes.

   Consequence, in the NHTSA record

   A separation of the splined and non-splined tubes could cause a loss of steering control and increase the risk of a crash.

   Remedy, in the NHTSA record

   Dealers will inspect the steering shaft using a weld placement gauge and miswelded steering shaft will be replaced free of charge. The recall began july 31, 2009. Owners may contact kenworth at 1-425-828-5440 and peterbilt at 1-940-591-4196.

   Report filed by PACCAR INCORPORATED. Manufacturer campaign number 09KW8 & 609-C. Owner notification date in the NHTSA record: 31 Jul 2009.

10. 09V239000Received 30 Jun 2009. 3,423 units.

    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.

    Report filed by PACCAR INCORPORATED. Manufacturer campaign number 09KW7. Owner notification date in the NHTSA record: 20 Jul 2009.

11. 09V229000Received 18 Jun 2009. 9 units.

    Power Train / Axle Assembly

    Defect, in the NHTSA record

    Kenworth is recalling 9 my 2009 t800s vehicles equipped with dana front axle. The brake spider mounting fasteners attaching the brake spider to the front steer axle flange may have received insufficient torque during the installation process. The insufficient torque may allow the brake spider fasteners and brake spider to become loose.

    Consequence, in the NHTSA record

    This can allow the fasteners to shear and fall either onto the roadway or into the drum brake assembly, potentially allowing the brake to bind and causing increased stopping distance and a crash could occur.

    Remedy, in the NHTSA record

    Dealers will inspect and replace the brake spider mounting fasteners and torque them properly, as well as review the brake spider and steer axle flange holes for signs of vibration and fatigue and replace if necessary. This service will be performed free of charge. The manufacturer has not yet provided an owner notification schedule. Owner may contact kenworth at 1-425-828-5440.

    Report filed by PACCAR INCORPORATED. Manufacturer campaign number 09KW6. Owner notification date in the NHTSA record: 17 Jul 2009.

12. 09V166000Received 19 May 2009. 140 units.

    Defect, in the NHTSA record

    Paccar 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, in the NHTSA record

    This could result in reduced braking capacity and also a road debris hazard, increasing the risk of a crash.

    Remedy, in the NHTSA record

    Dealers 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.

    Report filed by PACCAR INCORPORATED. Manufacturer campaign number 09KW3. Owner notification date in the NHTSA record: 15 Jun 2009.

13. 08V485000Received 24 Sep 2008. 130 units.

    Suspension

    Defect, in the NHTSA record

    Paccar is recalling 130 my 2004-2009 t2000, t800, t600, w900 and t660 kenworth trucks built with an ag400 rear suspension, long stroke brake chambers, and wide base tires (super singles). These vehicles may develop an increase in lateral and vertical axle movement. This movement may cause part or parts of the brake assembly (brake cam tube support, brake chamber bracket, brake chamber, brake spider) to develop fatigue cracks, possibly resulting in the failure of the part or parts within the brake assembly.

    Consequence, in the NHTSA record

    A failure may reduce vehicle brake performance, increasing the risk of a crash.

    Remedy, in the NHTSA record

    Dealers will install the cam tube support brackets on all of the rear axle wheel ends. Inspect the rear axle brake assembly and replace it if cracked. The recall is expected to begin during november 2008. Owners may contact kenworth at 1-425-828-5440.

    Report filed by PACCAR INCORPORATED. Manufacturer campaign number 08KWB. Owner notification date in the NHTSA record: 26 Jan 2009.

    Report filed by PACCAR INCORPORATED. Manufacturer campaign number 08KWC 908H.

16. 08V431000Received 25 Aug 2008. 86 units.

    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.

    Report filed by PACCAR INCORPORATED. Manufacturer campaign number 08KWA & 708F. Owner notification date in the NHTSA record: 28 Aug 2008.

17. 08V314000Received 14 Jul 2008. 1,189 units.

    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: 12 Aug 2008.

18. 08V128000Received 21 Mar 2008. 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.

    Report filed by PACCAR INCORPORATED. Manufacturer campaign number 08KW3 308E. Owner notification date in the NHTSA record: 14 Apr 2008.

19. 08V104000Received 10 Mar 2008. 318 units.

    Trailer Hitches

    Defect, in the NHTSA record

    Paccar is recalling 318 my 2007-2009 kenworth t800, w900, and peterbilt 357, 365, 367, 378, 379, 384, 385, 386,388, and 389 trucks equipped with premier trailer hitch assemblies. The pintle hitch assemblies may have been manufactured in a manner resulting in a reduction of fatigue strength of the pivot pins.

    Consequence, in the NHTSA record

    This reduction of fatigue strength could cause the pivot pin to crack and eventually break, causing the trailer to detach from the truck while in motion, which could cause a crash that could result in personal injury or death.

    Remedy, in the NHTSA record

    Dealers will replace the potentially defective pivot pin free of charge. The recall began on april 18, 2008. Owners may contact kenworth at 1-425-828-5440 or peterbilt at 1-940-591-4196.
