Why does my starter make a grinding noise when I start up?

First, the most likely cause is the starter clutch getting tired and worn. It is the over run clutch that lets the starter gear that engages the ring gear on the clutch basket spin faster than the starter as the engine catches. It is a sprag clutch that starts to make that noise in the early stages of failure.

Why does my Harley Davidson engine grind when I start it?

Even when everything is right, “Hot soak” re-starts can draw a bunch of current. Heavy current draw places a large voltage drop across the solenoid. Starter pinion releases and then grinds or starter just can’t push through compression quickly and engine kicks back causing ring gear grinding.

What should I do if my starter is grinding?

Put a 1/8″ drill bit between the flywheel teeth and the starter shaft. If it’s too tight, add shims till it clears. If it’s too loose, remove shims. (You must log in or sign up to reply here.)
