Western Star Conventional: Engine

Affects Western Star Conventional · 1983 — about 43 vehicles.

The hazard

On certain trucks with Cummins NH and K series engines - an interference may occur between the throttle lever stop pin and a rivet securing a side plate on the fuel pump housing - manufacturing assembly techniques may cause a stack-up and interfere by as much as .002" with the rivet. In come instances, the stop pin on the throttle lever can interfere with the rivets which retain the side cover plate on the fuel pump body. Depending on the orientation of the throttle lever, it is possible for the throttle to become impeded in any position. From idle to wide open throttle.
