]I'm tearing down the transmission of my 27 t and was quite surprised to what I found. This car has not been started in about 20 years and I was the last one to run it, I don't remember any serious issues when it was last started. I decided to start a frame up restoration, with the frame, rear end, and front end done the next was to tear done the motor. With hogs head off I was surprised to find 5 broken mag screws, a very beat up magneto coil,5 mag clamps at various locations and the starter ring teeth on one side damaged (not totally missing, but dinged up). I'm debating if I can just rotate the ring gear. 180 degrees and us the undamaged side of the ring gear. Enclosed are pictures of dinged up ring gear which I want to rotate, but looking for a little advice
Can I turn flywheel ring gear

Re: Can I turn flywheel ring gear
The starter engages on two places on the ring gear, opposite one another, when the motor comes to rest. What you are seeing is normal wear. Some cheapskates will rotate the ring gear 90 degrees so the bendix engages on a new set of teeth, but I think that is false economy. You will need to disassemble your flywheel to rebuild it. That requires testing each magnet for cracks/breakage, fitting replacement original keepers and a new set of screws. It is pointless not to fit a new ring gear at this time.
Hope this helps.

Re: Can I turn flywheel ring gear
Do you mean flip it front to back? No, it is machined to engage on one face only.

Re: Can I turn flywheel ring gear
No, simply rotate for fresh set of teeth where the Bendix first engages the gear.
I know the voices aren't real but damn they have some good ideas!

Re: Can I turn flywheel ring gear
Starter Ring gears, transmissions, mag rings and other engine internals are not things to take short cuts on, unless you enjoy pulling engines and tearing them down to repeatedly repair...
