NHTSA recall campaign
05V451000
What was wrong
Defect
ON CERTAIN MEDIUM DUTY TRUCKS, THE CYLINDER HEAD IDLER GEAR SHAFT BOLT MAY HAVE BEEN INSUFFICIENTLY TIGHTENED DURING INITIAL ASSEMBLY. CONTINUED OPERATION IN THIS CONDITION COULD CAUSE THE BOLT TO LOOSEN, RESULTING IN ABNORMAL NOISE FROM IMPROPER GEAR ALIGNMENT.
Risk
THE BOLT COULD BREAK, CAUSING THE ENGINE TO STALL AND NOT RESTART, INCREASING THE RISK OF A CRASH.
Manufacturer remedy
DEALERS WILL CHECK THE IDLER SHAFT BOLT. IF THE BOLT CANNOT BE REMOVED BY HAND, A MODIFIED IDLER SHAFT BOLT WILL BE INSTALLED. IF THE BOLT IS LOOSE ENOUGH TO BE REMOVED BY HAND, A NEW IDLER GEAR, IDLER SHAFT, AND A MODIFIED IDLER SHAFT BOLT WILL BE INSTALLED. THE RECALL BEGAN ON DECEMBER 20, 2005. OWNERS MAY CONTACT MITSUBISHI FUSO AT 1-856-467-4500.
