SITUATION:

KNOCKING SOUND WHILE STARTER OPERATING, OR STARTER FAILURE

The customer may complain that a knocking noise is heard when the starter motor is activated.  The noise will go away when the engine starts and the starter disengages.  The starter pinion may be coming in contact with original style drive plate balance weights.

 

RESOLUTION:

INSTALL NEW DRIVE PLATE BALANCE WEIGHTS

New configuration drive plate balance weights have been developed to eliminate the potential contact with the starter during engagement.  The new weights should be installed when a customer complaint is confirmed and whenever a new starter is installed on vehicles within the affected VIN range.

 

PARTS INFORMATION:

NOTE: The new 9.5 gram weight replaces the original 9.5 gram and 9.7 gram weights, (Refer to items 4 and 5 on Attachment 1).
