Recall 1150310 — Turbocharger

Overview

Defect

In the engines of these large trucks, microscopic voids may be present at the maximum stress point of the turbocharger turbine impeller during secondary resonance. These voids act as fatigue crack initiation sites, causing the turbine impeller to fracture and producing abnormal noise, white smoke, power loss, and engine warning light illumination. Continued operation causes abnormal vibration in the turbocharger, which fatigues and cracks the turbocharger oil supply pipe. Oil leaking from the cracked pipe contacts high-temperature surfaces and may result in a vehicle fire.

Corrective action

On all vehicles, replace the oil supply pipe, coolant supply pipe, and pipe mounting bracket with corrected parts. If the turbine impeller has already fractured due to this cause, the turbocharger will be replaced at no charge.
