2011 KENWORTH T270 Recalls (3)

Campaign:
10V211000 on 05/17/2010
Component:
Service brakes, air
Manufactured:
01/27/2010 - 03/18/2010
Affected:
22
Defect:
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.
Consequence:
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.
Correction:
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 began on june 10, 2010. owners may contact kenworth at 1-425-828-5440.

Component:

Manufactured:

Affected:

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.
