Replacing Ring Gear/Flywheel: Help!

The teeth are so worn on the ring gear of my family's 1957 Allis Chalmers D-14 that it has become apparent that the ring gear must be replaced. A local shop just put a new gear on the starter, so that's not the problem. My question is: Is it necessary to split the tractor into two sections to do this repair and if so how does one go about doing this?

Yes you'll have to split it in two--remove the flywheel--get a new ring gear,cut off the old one and you will notice a "pin" in the flywheel to locate the new gear, /it fits snug so you have to heat it with a torch to expand it enough to go on Its not a big deal--If you can do the rest you can do the ring hope this helps Jim in N M

you don't need a new ring gear just flip it over. plan on new clutch too.

If you flip the ring gear over & it had a chamfer on the working side you will have to grind a chamfer on the new working side, or the starter drive will not engage correctly & will clash each time it's engaged.

I'll buy that Clooney! Don't turn it over and use it unless theres not another one to be had. Starter would burr them up and probably wedge and not come off flywheel. Engines have a tendency to stop in same place lots of times. Result; same part of ring gear gets worn when started. Temporary solution; kill engine with clutch and it will generally stop in another spot. To remove ring gear, place on fire brick and heat 2 to 3 inches of ring gear red. It will come right off. To install new one, place on fire brick and heat evenly all the way around ( but not red) and it will expand about a 1/32" and you can stand back and throw it on. Make sure beveled teeth face toward starter when you throw. Fred from the Mung Factory

Tell ya what I saw a guy do once on a jeep flywheel. He put the flywheel in a garbage bag and put it in his chest type freezer. Then he put the flywheel gear in his wifes oven, and heated it. That sucker nearly fell on. Durndest thing I ever saw!

Sam you might as well tell 'em how to get it off real easy. Just drill a pretty good sized hole just about through it and hit it with a cold chisel there. Bingo Fred from the Mung Factory

in the 1950s turning it over worked well, i know of 4 sill going. no problem engaging or coming out. another way was to move the ring gear 8-10 teeth on the flywheel. this was back when a quarter looked like a wagon wheel.

Hi Joe from Fred I liked everything you said in your reply and I'd love to see a quarter that big again. But times have changed and labor is expensive and today we not as apt to taking a chance as we were back then. It actually sounds like something I'd do today to a piece of my own gear or even weld in new teeth and grind them down. But just between you and me,( Nobody else is reading this old post) I wouldn't tell the rest of 'em to do it cause if they had to pay the labor to tear it down and do it again, they'd be throwing email alley biscuits at me.

Hi Fred I sort of wanted to put a little history lesson here.

Fred,I really like your idea to stall with the clutch. Simple but effective. I'll bet it really works good on 2cyl. engines, they almost always stop in the same place.

I don't cut off the old ring gear. I generaly just use a brass punch and tap it off. Neal
