I have a John Deere 70 gas that needed some starter work. With the flywheel cover off and the starter out I noticed primarily one spot on the ring gear that is really worn. Possibly 1/2 way through the teeth. I had noticed that once in a while the starter would grind. Is the only solution replacement of the ring gear? Are they ever turned around or welded up? Has anyone replaced one lately? Just wondering who supplies a good one at a reasonable price? Thanks.

(Part No: A2238R) is This site's ring gear for that tractor. Quality has not been an issue with YT parts. Turning it around is OK so is just turning it 20 degrees or so to get a new stopping point for the gear to be at the starter. Jim

Since the flywheel will be off and you will be heating the ring gear anyway you had just as well throw a new ring gear on it.
New ones are available for a little over a hundred bucks, replace it, for gosh sakes.
If you opt go the "cheap" way and "turn" it, if the starter drive gear ever happens to "crawl" up and over the damaged teeth and breaks the starter "nose cone" and bends the armature shaft it will cost a LOT more to make things right again!

Giving it a quarter turn will work if it isn't too bad. All engines will wear the ringgear in either two or three spots. starter engages and there is always some gear clash as part of that which slowly wears down both the starter and ring gears.
That said if you replace I would suggest one of the aftermarket outlets like the parts button to the left. I got one for a 50 A a number of years ago from Mother Deere and had to pick my jaw up off the floor when I saw the price, I think it was $400 or something.

Halfway through the teeth? That's a lot of wear. . .
I have flipped them in for out back when times were hard and things were bad, but I'd check the price of a new one today. One side of the ring is beveled and the other side is not. When I flipped one, I would pull start it with the flywheel cover off, then carefully make a bevel with a weld grinder while the engine was running. It just takes a touch of the grinder to make the bevel.
