Sheared starter drive bolt
I went down to the shop after work to do the usual battle with this new to me AA cut down truck. Before I could deal with the issues I wanted to address The starter spun but didn't turn the flywheel... So I started it with the crank..... But I want electric start. I pulled the starter and found a sheared off bolt. My wife was due home in 20 minutes ... A bolt had sheared off in the drive. 12 v conversion done by PO ,,, any surprise?> Looking at the green bible I see the drives are similar. I have a half dozen Flathead v8 starters here in a heap. Are the bolts the same? Do I* need to order some starter drive bolts or do I already have some? Wife and I in the middle of dinner now............

Re: Sheared starter drive bolt
the Model A starter drive used 5/16" bolts and they break all the time. the V8 starter drive uses 3/8" bolts, I run the V8 drives and have not broke a bolt in many years. check and see what bolts you have. if you are running a 6 volt starter on 12 Volts it is going to engage hard and that is hard on the drives and or the bolts.

Re: Sheared starter drive bolt
With 3/8" diameter Bendix bolts properly installed with the special lock-washers and a new spring, I have been running 12V in my Coupe with a stock starter motor for many years without issue.

Re: Sheared starter drive bolt
Thanks! Just came in from the shop. Direct replacement. Wish all repairs and modifications were that straight forward. That starter drive interchanges from '28-'53. The year my mom was born until the year that I was born!
