If the starter keeps spins when the drive kicks out then I suspect a Bendix problem. Some of the older starters had a clutch type Bendix and could fail in this way but hard to diagnose on the bench. The starter repair shop could probably verify this.

Default Starter problem

Jim: I have a used Skytec 149-12PM starter you can have for $150 plus shipping. Perfectly operational. If it will work for you and you are interested send me a PM or email to happ@comcast.net.

Default Reviewing Everything and Found this today.

Pulled starter back off today and while I was underneath decided to take another look at the ring gear using a very bright light as well as feeling. Previously looking from above in ambient light, I failed to see this. Today, I noted the rear corner of several teeth had been knocked down/chipped off? It is a small area. Is this enough alone to be cause of my problem. Still, I am ordering a new ring gear to replace this one. I am assuming it contributes as it makes two blades and kicks out almost every time.







And yes, I feel like an idiot for having missed this the first time I looked before tackling the electrical and starter track.

Looking at your pictures it looks like the starter gear is contacting the back of the ring gear and not even engaging the teeth. Look closely at the alignment of the starter.

Default Teeth?

Jim,

Do you know the number of teeth the starter is set up to run? I have an old Prestolite (should just be Presto...nothing light about it) in the shop I'm not using. You might either use it as is or just change the gear if you need the other tooth count. PM or email me if you like.

I definitely appreciate the offer, but it does not appear that model will fit on my plane as it is configured.

I am thinking that the damage you are finding on the ring gear is a symptom of your problem, and not the cause. The mechanical mechanism that engages and disengages the pinion gear is not functioning properly.

Thanks. That reinforces my thoughts as well. I'm trying to track down a replacement Bendix drive assy 480388 F8 to swap out as well.

Had the same problem on an old Pontiac years ago. Changing the bendix drive itself is what fixed my issue.

You might be able to find a replacement Bendix unit at NAPA auto parts.
