JULY 2010 -- 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. A separation of the splined and non-splined tubes would cause a loss of steering control and increase the risk of a vehicle crash. 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. Kenworth's recall campaign number is 10KW-F & Peterbilt's recall number is 0610-D. 10V-308

SEPTEMBER 2009 -- 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 after treatment 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. 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. Paccar is working with Cummins to repair the engines free of charge please see 09E-046. The safety recall is expected to begin during September 2009. 09V-348

MAY 2009 --  Paccar is recalling 112,736 trucks equipped with caterpillar C15 engine. The variable valve actuation oil line may rub against the p-clips retaining the oil line, causing an oil leak. An oil leak may result in a fire hazard.Paccar is working with caterpillar to remedy these vehicles. Please see recall 09E-020. Caterpillar will inspect and repair the necessary components free of charge. The manufacturer has not yet provided an owner notification schedule. Owners may contact caterpillar toll-free at 1-800-447-4986, Peterbilt at 1-940-591-4196 and Kenworth at 1-425-828-5440. 09V-165

SEPTEMBER 2008 -- PACCAR is recalling certain 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. A failure may reduce vehicle brake performance, increasing the risk of a crash. PACCAR has not yet provided a remedy for this campaign. The recall is expected to begin during November 2008. Owners may contact Kenworth at 1-425-828-5440. 08V-485

SEPTEMBER 2008 -- PACCAR is recalling 263 MY 2008-2009 Kenworth T800, W900 and Peterbilt 365 and 384 trucks equipped with C7 or C9 Caterpillar diesel engines. The fuel pump outlet check plug may be cracked which could cause fuel to spray and leak. Fuel leakage, in the presence of an ignition source, could result in a fire. PACCAR is working with Caterpillar (please see 08E042). Caterpillar will replace the fuel pump plug free of charge. Owners may contact Caterpillar at-1-800-447-4986 or Kenworth at 1-425-828-5440 or Peterbilt at 1-940-591-4196. 08V-486

SEPTEMBER 2008 -- PACCAR is recalling 3,640 MY 2006-2009 Kenworth T600, T660, T800, W900, T2000 and MY 2008-2009 Peterbilt 365, 367, 379, 384, 386, 387, 388 and 389 trucks. Inadequate stiffness of the diesel particulate filter (DPF) bracket could result in separation of the DPF from the chassis. A vehicle crash could occur if another vehicle strikes the DPF on the roadway. PACCAR is working with Caterpillar to repair these vehicles (please see 08E041). Owners may contact Caterpillar at 1-800-447-4986 or Kenworth at 1-425-828-5440 or Peterbilt at 1-940-591-4196. 08V-487
