Dreaded Starter Grind

Postby Moosehead » Tue Jun 26, 2018 8:19 am

A starter grind has shown up lately which does not allow ignition. New starter, alternator, battery in a Jasper rebuilt engine.

It has only happened twice and does not allow ignition. I stop trying after first or second attempt so as not do damage the flywheel ringdrive teeth. First incident went and recharged the battery which showed 75% charge before top off - started fine for a few days. Second time, she started second effort after grind showed up first attempt. Will analog clock (working) draw down the battery over time in these systems?

Have seen many other threads on the issue including perhaps need for new starter, better battery/charge, shims on the starter, other.

Any tips would be much appreciated.

There may be a spot on the flexplate ring gear that is chewed enough that the starter has trouble engaging there. It was a source of cursing for me once.

A new flexplate is not all that expensive. If you have a manual gearbox, you can still get a new ring gear and install it on the flywheel with some heat.
Often both styles will develop a warp/out-of-round and the starter drive gear will chew up an area where then engine stops.

Does your starter need shimming?

Tighten the starter bolts? Did you check?

Thanks fellas, replaced a cheaper reman starter. So far, so good, though voice in my head says that's been done before here to no avail.

Did check shim/bolts/elect.
