Changing Ring Gear on Super C

Seriously, when I did mt Super A with flywheel still on tractor, a neighbor IH technician came with torches. He hung the new ring gear on a coat hanger, passed me the welding gloves. As the old ring came loose, I pulled it off using gloves, while he turned to heat the new one. I went around the flywheel with wire brush, and no sooner laid the brush down until he had gloves on coming with new ring. My guess is this probably took less than 5 min. He just went continuous around the ring with torch being very careful not to get it red. It's surprising how little heat it takes.

I replaced all the clutch parts. The machine shop at the local NAPA that turned the flywheel sold and installed the new ring gear for me. I think the new ring gear was around $30 and installation was a couple bucks more.

All in all a good deal.

FWIW - While it will work I don't recommend flipping and reusing a worn ring gear. Rather put a crowbar to your wallet and buy yourself a new one! It'll cost <$40. After the time/effort you go to split the tractor it'll be money well spent...

Once you get the flywheel off, set it clutch side down on a block of wood that is small enough for the gear to fit over. Most ring gears come off towards the clutch side, but check to be sure. If it looks like it comes off the other way, just turn the wheel over. Be sure the flywheel is solidly supported, you don't want to be chasing it around, or picking it off your toe half way through the job. Heat the gear with a torch, working evenly around it and occaisionally tapping with a small hammer until it loosens up and falls off. Turn the flywheel over and lay the new gear on it with something to hold it up. I usually lay a couple of welding rods across under it. You can also just heat it somewhere else, and pick it up and move it when it's ready. Heat the new gear carefully and evenly until it is just hot enought to melt a piece of solder laid on it, then pull out your supports and quickly tap the gear onto the flywheel. Make sure it seats tightly all the way around. I use a small hammer and a brass punch to do this.
