The problem
Paccar is recalling 1,043 my 2008-2009 kenworth c500, t2000,t660, t800 and w900 trucks equipped with bendix mv-3 dash control valves. The molded valve body has an incorrect core pin in the injection mold causing the valve body to be oversized in the double check valve area. This condition can allow the rubber double check valve to become lodged in the body opening under certain circumstances.
The risk
If the double check valve becomes lodged, in the event of a primary reservoir failure, air pressure can leak past the lodged double check valve thereby depleting the secondary reservoir, Causing reduced ability for modulating the service emergency brakes. In such an event, the operator should observe an air leak, indications of low air pressure via the primary and secondary air gauges, and audible and visual low air pressure warning alarms. A vehicle crash is possible if these warnings are not heeded.
The fix
Dealers will replace the bendix mv-3 dash control valves free of charge. The recall began on april 14, 2008. Owners may contact kenworth at 1-425-828-4196.
