Flywheel ring gear for 210B

Some time ago I replaced the clutch on my 210b and instead of replacing the ring gear I took it off and reversed it. It seem like a good idea until it caused the end of the starter to blow off. I took the starter to someone and had them replaced the casting and ordered a new ring gear this time. Now that I have it apart again I find out that someone put a different ring gear than what it called for. According to my parts book the ring gear was suppose to be a VT4524 with 96 teeth and is what I ordered and received. Now I find out the ring gear that is on it is a G11274 with 124 teeth. Both ring gears have the same id however the od on the VT4524 ring gear is 13/32" smaller in diameter. I attempted to start over and get another ring gear like it has had but Case has discontinued it and others have told me the ring gear is not available in the aftermarket. I then tried to get my local tractor mechanic to change the gear on the starter to match the new ring gear but he didn't like the idea. He said it would turn the engine too fast. I would do it myself but there is no identifying marks on the starter so I don't know which 12v starter I have and I sure don't know which gear it should have. Any ideas on what I should do?

The only thing to do is fix it right. Put the correct 96T Ring Gear on & the correct Bendix Drive which is 10 Tooth. BTW, find a new starter man. "Spin too fast"?? Good luck.

My 211B is 6 volt. Was the 210B 12v ?

I think all 200B Series were 6V, but it doesn't matter, Steve needs a 10 Tooth Pinion for the 96 Tooth Ring Gear.

That was my thought. If it was suppose to have a 96 tooth ring gear, than I should make the starter match it. It looks like the bendix I have now is 1 3/16" in diameter and 9 teeth. Another question, is the diameter of the 10 tooth bendix 1 19/32 in diameter to make up for the ring gear being 13/32" smaller od?

I've been in communication with John via email and he took the starter off his tractor to be sure and the gear on the bendix is the 10 gear and it is 1 9/16" in diameter where the old one was 1 1/8" used with the G11274 ring gear.
