Default can this be fixed?

The best laid plans..... I had a starting issue with the car when hot, so I bought a high torque mini starter.

It occasionally made a grinding noise, but started just fine. Its been on there about a month now with lots of starts and stops.

Well.. it made a brand new noise in the garage today, so I pulled off the starter and took a look at my worst fears confirmed






Is there any way possible to fix this without replacement? I JUST dropped the motor in early march, I really dont want to have a do-over of that. I turned the motor all the way around and could find no other "missing" teeth..

I guess the better question to ask is "Which flywheel should I look into for a 383 stroker with a street/strip McCleoud oem style clutch freshly installed on it?

Your pictures didn't post, however most flywheels have a replaceable ring gear.

Are you asking if it can be fixed without removal of the motor or transmission?

Yes.... but I already knew the answer before I posted it. It was more "venting" than anything else.. Although maybe someone came up with a new magic way to fix it since the last flywheel I toasted 10 years ago...

It also appears that the depth of engagement of the starter pinion is not deep enough, or maybe it shifted to cause that. Bottom line, don't simply install another flywheel or ring gear without checking the engagement of the teeth. A good gauge is to use a folded business card to set the depth.

My thoughts exactly. You can also make a fairly accurate guage for engagement between the ring gear and starter by bending a regular size paper clip.
It's really a shame something like this happened. I know you have been doing a lot of work on your car for quite a while and nobody needs unexpected problems. Hopefully the fix will go well.

The starter - PWM-9200 STARTER STAGGERED 168 TOOTH

It works great, I really liked it to be honest. The car usually turned over within 1 - 2 seconds of turning the key.

I should have checked the engagement, but I literally played this one by ear. It sounded great and felt fine. I never had any problems with it other than an occasional clunk/grind every once in a while. It was rare enough that I just shrugged it off. Then the wife was at the gas station with it the other day, as I just found out, and it made a terrible noise when she went to start it, so she just let it roll and dumped the clutch to drive it home Not that knowing that before i tried to start it would have done me any good. Just too bad.. Im so busy I may not have time to pull it apart for a while, may have to bite the bullet and take it to a shop so

Is this just an issue of correct engagement or are high torque mini starters prone to screwing up the flywheel?

That's why I never installed my way too expensive mini starter. The tooth engagement was about 1/4 not even half way. I don't understand it. 2 billion small block chevy motors made and they can't make a mini starter that engages the full tooth of the flywheel ?

The only reason I got this one was due to the other one getting too hot... Headers were just a little too close and after a long trip it had to cool off a bit before it would work. I know it's my fault for not checking engagement, but had the attitude of "Well they sell hundreds of them and it sounds fine.. Im sure its okay"

And thats why I got a GM mini starter, engagement is excellent and so far so good.

I've had a GM high-torque mini-starter (#12361146) for years with no visible wear on the flywheel teeth. I switched to a ht mini to avoid heat-related starting problems with headers.

Just checked and I believe my problem is the lightweight flywheel I have, I think to make it lighter they have to make it thinner and in doing so it removes a portion of the teeth on the inside. Oh well
