Campaign:
10V453000 on 10/05/2010
Component:
Engine and engine cooling:exhaust system:emission control:gas recirculation valve (egr valve)
Manufactured:
04/18/2010 - 07/26/2010
Affected:
384
Defect:
Paccar is recalling certain model year kenworth and peterbilt vehicles. a manufacturing defect in the seal supplied by a component manufacturer installed on the output shaft of the exhaust gas recirculation (egr) valve actuator may cause eventual delamination of the seal. delamination of the seal may allow engine oil to leak from the egr valve onto exhaust components.
Consequence:
The leaking of engine oil onto hot exhaust components, such as when the engine is under significant load, may create the possibility of a fire.
Correction:
Dealers will replace the egr valve assembly on the subject vehicles equipped with the paccar mx engine. this service will be performed free of charge. the safety recall began on october 29, 2010. owners may contact kenworth at 425-828-5440 and peterbilt at 940-591-4196.

Campaign:
10V535000 on 11/01/2010
Component:
Service brakes, air:disc:caliper
Manufactured:
12/21/2008 - 08/01/2010
Affected:
417
Defect:
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:
As this interference gets larger, this could eventually lead to reduced braking performance, increasing the risk of a crash.
Correction:
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.

Component:
Latches/locks/linkages:hood:latch
Manufactured:
08/08/2010 - 11/03/2010
Affected:
1,510
Defect:
Kenworth is recalling certain model year 2011 t660 and t700 tractor trailers manufactured between august 9, 2010, and november 4, 2010. the safety latch feature that keeps the hood of the vehicle from closing after a user opens the hood may fail to operate.
Consequence:

Campaign:
11V127000 on 02/24/2011
Component:
Fuel system, other:storage:tank assembly
Manufactured:
02/18/2007 - 02/22/2011
Affected:
4,664
Defect:
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:
The discharge of engine oil onto exhaust components which are hot, such as when the engine is under significant load, may cause a fire.
Correction:
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.

Campaign:
11V157000 on 03/09/2011
Component:
Service brakes, air:slack adjusters
Manufactured:
10/17/2010 - 01/27/2011
Affected:
280
Defect:
Paccar is recalling certain model year 2011-2012 kenworth t270/370, t440/t470, t800, t660, w900 and c500 vehicles manufactured between october 18, 2010, and january 28, 2011. certain cast iron slack adjuster housings, which transmit braking force from the brake chamber push rod to the brake cam tube, may include a flow notch in the handle portion of the housing due to an error during the casting process. a flow notch in the handle portion may reduce the effective cross section structure and cause the slack adjuster housing to fracture.
Consequence:
If the slack adjuster housing were to fracture, the wheel brake to which the slack adjuster housing is attached would no longer function, which could increase vehicle stopping distances, and if mounted on the steer axle, could cause the vehicle to pull to one side during braking, increasing the risk of a crash.
Correction:
Dealers will inspect and replace the slack adjuster housing as necessary. this service will be performed free of charge. the safety recall began on march 30, 2011. owners may contact kenworth at 425-828-5440.

Consequence:
This could result in a fire.
Correction:
Caterpillar is handling the owner notification and remedy for this campaign. please see caterpillar's defect report 11e-006. caterpillar will replace the single piece combustion tube with a thick wall combustion tube which will not allow the heat to break through. this service will be performed free of charge. due to a parts supply issue, owners will be notified by the end of april 2011 about the safety defect, and will then be notified again once the free remedy is available, currently estimated to be around late july 2011. owners may contact caterpillar toll-free at 1-800-447-4986.
