JUNE 2010 -- Kenworth is recalling certain model year 2009 through 2010 T660 tractor trailors manufactured from July 1, 2008 through July 31, 2009. The retaining pins securing the hood strut lock tube to the hood strut assembly may become loose and fall out allowing the lock tube to rotate on the strut assembly. In its normal operation the safety latch feature is automatically set and it prevents the hood from closing. With the hood closed and the retaining pins missing, the lock tube may rotate relative to the good strut resulting in a non-operational safety latch feature when the hood is opened. A non-operational safety latch feature may not be detected by an operator increasing the risk of personal injury and/or vehicle damage should the hood unexpectedly close. Dealers will replace the pivot disc and lock tube retaining pins with a revised pivot disc and cap screws. This service will be performed free of charge. The safety recall is expected to begin during June 2010.  Kenworth"s safety recall number is 10KWE. 10V-266

MAY  2010 -- Kenworth is recalling certain model year 2010 T2000, T660, T800 and W900 vehicles manufactured between July 30, 2009 and September 18, 2009. The rear axle outer end hub may have not been primed with oil properly during the rear axle installation process. Potential lack of oil may cause the outer end bearing to heat up and/or seize, possibly resulting in the overheating of the wheel end. A wheel end fire may occur, increasing the risk of a crash. Dealers will replace the bearings, seals and will add oil to the outer end hub as well as inspect races and axle housing for damage and replacing as necessary free of charge. The safety recall is expected to begin during June 2010.  10V-185

MAY  2010 -- Kenworth is recalling certain model year 2011 T270, T370, and T800 trucks manufactured from January 28 through March 19, 2010, equipped with DV-2 air governor containing part number G90-1070- 2111111 on the T270/370 model trucks and part number G90-1070-11113111 on the T800 model trucks. The DV-2 air governor was misassembled with a blank plug instead of a breather. Without the breather installed, the air governor may not be able to detect the loss of air pressure in the air system during normal use. This condition may result in the slow activation of the emergency spring brakes. Although the operator is warned of low air pressure by audible and visual low air pressure warning alarms, a vehicle crash or fire is possible if these warnings are not heeded. Kenworth will notify owners and repair the vehicles by replacing the blank plug with a breather and inspect for proper function free of charge. The safety recall is expected to begin during June 2010.   Kenworth's campaign number is 10KWD. 10V-211

MAY  2010 -- Kenworth is recalling certain model year 2009 through 2011 C500 trucks manufactured from October 24, 2008 through January 13, 2010. During maneuvers with certain combinations of wheel turn, articulation, and bump, the brake chamber can contact the rear hood support. The contact can damage the brake chamber leading to a loss of braking function at the affected wheel end, increasing the risk of a crash. Kenworth will notify owners and dealers will repair the vehicles free of charge. The safety recall is expected to begin during June 2010.  . Kenworth's recall number is 10KWC. 10V-212

APRIL 2010 -- Kenworth is recalling certain model year 2010 T270 and T370 trucks equipped with non-LMS hubs. The spindle nut attaching the hub and bearing to the axle spindle (steer or drive) may have been over-torqued during the hub installation process. An over-torque of the spindle nut may cause the bearing to seize, possibly resulting in the overheating of the wheel end. As a result, a wheel end fire may occur. Dealers will replace the bearings free of charge. The spindle and hub will be inspected for scoring and replaced if necessary. The safety recall is expected to begin during May 2010.   10V-150

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

JUNE 2009 -- Kenworth is recalling 13 MY 2009 T2000 vehicles for failing to comply with the requirements of Federal Motor Vehicle Safety Standard No. 106, "Brake Hoses." Air tube expander fitting used between the air tube inlet and dash air gauges for the trailer does not meet the burst pressure requirements. This can result in brake hose rupture, air pressure loss, and compromised vehicle braking which could result in a crash without warning. Dealers will inspect and replace the expander fitting which is related to 1,200 PSI. This service will be performed free of charge. The manufacturer has not yet provided an owner notification schedule.  09V-227

JUNE 2009 -- 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. 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. 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.  09V-229

JUNE 2009 -- 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, can cause fatigue and cracking of brake assembly components. Cracking can cause a complete fracture of the cam tube, which could increase stopping distance and decrease parking brake hold capability. 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.  09V-239
