Ring Gear Wear Trouble

[Mag Man]

Hi Gents I dont know alot of you to well but am Glad to Hear Rudis doing wel l. Ok Lets get to Bussiness I have heard of people say that they have fixed a bad ring gear with a dremel. How do you do that?

Jon, when starter grinding damages the ring gear it usually leaves flattened or mushroomed edges on the ring gear teeth. What you do with the dremel is grind off those mushroomed edges to try to restore the tooth contour as completely as possible so the bendix gear on the starter will engage smoothly.

Also, there will be two problem spots 180 degrees apart. I've never done it with a Dremel, but have done it with a 4 1/2" griner when I had it split. Dremel should work, but will be more tedious, and may need the right angle attachment. Also check your starter drive, if it's flattened on the ends of the teeth it will quickly damage the ring gear teeth again. If you replace starter drive verify direction of rotation. They make identical ones for clockwise and counterclockwise.

I see John well the starter is primer brown or similar the guy said it was brand new but the bendex is bad to I guess besides the tractor coming to a stop at those spots on the ring gear every time it growls and kicks out a lot. I wish I had a HAND CRANK. OK now I am singing all's I want for Christmas is a CUB HAND CRANK, A CUB HAND CRANK, Well you get the picture its 5:00am been up since 2:00 cant sleep. Oh well I wonder if TM carries them? JON

Most auto parts stores can get the bendix. As I said be sure the spiral goes the right way. If the teeth on the bendix are blunt the flywheel teeth may not need much work. I think the teeth actually become blunt mostly from the starter drive just running into the ring gear. after a while the edges wear out. I redid the ring gear teeth on an H with a file once. Took a while.

If you are adventurous you can heat and turn the ring gear 90 degrees on the flywheel, or take it off and flip it over.

Never had this with a cub but did on a super A all I have to say is don't be cheap get a new or a good used one.
This falls under the heading of you can do this once or do it twice.

Had to look at the one on the shelf in my shed to verify my thinking, but the one I have does not have the teeth beveled on the rear side, so flipping it over would not be a solution.

I didn't say it was a GOOD solution! I'd heard a few people say they had turned their ring gears, but I've noticed that the back side is never beveled for good engagement too.
