Common Starting Issues It May Address

• Engine no-crank condition caused by a worn starter motor
• Slow or inconsistent cranking on 12-volt GM vehicles
• Starter drive engagement problems related to tooth wear
• Intermittent starting on Delco-style applications
• Replacement need after electrical starter failure

Installation Notes and Tips

Verify the starter’s 12-volt, clockwise, 9-tooth, direct drive configuration against the original unit before installation. Some 1984 applications require the second production version with a cast ear on the solenoid, so confirm the vehicle build details and existing starter design before ordering. This part cross-references AMS Automotive 6310 and 6317 for the same application.
