Default Starting issues

Getting an occasional loud shriek and no engine turnover when I try to start my 64’. Battery is new and cables all clean. It happened a few weeks ago after the car had been sitting a while. Today it happened after a hot restart with the AC compressor engaged. The ringear shows one bad section (in photo) but the rest isn’t bad.

Is it worth changing out the starter drive to see if it solves the issue? I really don’t want to have swap out the ringear!


Ring gear bad section

Sounds like the solenoid didn’t engage the pinion to the ring gear. Happens. If it does it again, rap on the solenoid with the handle of a screw driver or rock the car with the tranny in gear. Those ring gear teeth don’t look bad to me.

Thanks Factoid but is there something I can replace on the starter to prevent this? I KNOW this will happen again on one of the few times that my wife uses the car!

You might get lucky with the solenoid or starter drive, but it doesn't take much rounded off teeth on the ring gear to cause problems...
I had to replace the one on my '61..

I would try replacing the starter drive first. If you think the ring gear is the problem, I believe it can be turned around rather than buy a new one. That is assuming all the gears are in good shape on the other side of the ring gear.

You may get some life out of it if you replace the Bendix gear. I had to replace the flywheel ring gear on my 68. Cheap and easy to do except for pulling the tranny, pressure plate and clutch . Jerry

Yes - you can "flip" the gear if it hasn't been done already...

Ring gear looks very bad to me.

You might try putting an edge back on the ring gear teeth and see if that helps. I've never tried it.

The other side of the ring gear is like new. It’s the flipping it around part that has me annoyed !!! hopefully, the starter drive replacement will fix it, at least for awhile. Been looking at the underside of this car for far too long...

The issue is getting it out - once removed its a matter of flipping it with a heating and cooling process IIRC....not my area of expertise but others will know the process...

Without a lift it would be a real PITA for me to do this. Would probably have to farm it out to a pro. Hopefully, a new bendix drive will fix it, at least for a while.

Try the new Bendix drive. If that doesn't work, have a NEW ring gear installed. Not worth all that labor to pull the trans and try to jury-rig the old ring gear. I agree with Mike M: your ring gear is rough with a lot of chipped teeth. Indicative of an improperly shimmed starter and or a bad Bendix not engaging properly.

Agree on the ring gear replacement if the bendix drive doesn’t resolve the issue. It would only be a small additional cost in a professional repair job.

JFP, I think those peened-over areas of the gear teeth will be too hard to file. You might have better success with a diamond grinding bit for your Dremmel tool. There are several styles to pick from. Here is one: Diamond Grinding Tool

Or some kind of abrasive tool to restore the edge. Like a lawn mower blade.

When an engine stops turning when you turn the key off, seems like the crankshaft always wants to stop in the same place(s). That can wear the ring gear in one place. A bad starter drive would make the problem worse.

Yeah, seems like that happening since most of the teeth look fine. The really messed up ones are only in one area.
