CONDITION:
Some owners of the above vehicles may comment on hard start, grind or clash noise during an attempted start. The starter may not
properly engage the ring gear. A loud grinding noise occurs and the engine does not crank. The engine may crank normally on
repeated attempts to start.
CAUSE:
The spring in early design SD210 / SD260 starter drives may compress too easily. This may keep the drive pinion gear from
snapping into mesh with the ring gear as the starter motor starts to turn.
CORRECTION:
Follow the unit repair manual (Section 6D2) and replace the starter motor drive assembly with part number 10473700. Inspect the
flywheel for signs of milling or material loss at the engagement points. Repair as required.
The new starter drive with the stronger spring has been released for all SD210 and SD260 starters.
Parts are currently available from GMSPO.
