2011 KENWORTH T800 Recalls (11)

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.
