Replacing flywheel ring gear Chapter 2

Dr. Bert · Feb 8, 2012

Got the tractor split this PM (easily done). Now my question--has anyone tried knocking off the old ring gear and installing a new one without removing the flywheel? Obviously would heat the new one. Thanks. Bert

It is like 8 bolts. Just take it off. There are 4 on the pressure plate and 4 to hold the flywheel on. I would be checking the PP for warpage and the clutch disc for wear anyhow. I might just put a clutch in it since they aren't really outrageous. I would also be looking for signs of the rear main seal leaking.

To get the old one off start a cut with the die grinder and whack it with a cold chisel. I have never done it, but I hear it works.

It does work.

If you score it witha small cut off wheel in a low spot in between the teeth and smack it with a BIG chisel and hammer,it will "give up".

After removing from the crank, they come off very easily with a little heat applied, not red, just warm enough to expand a bit, then tap with a hammer a few times to the rear.
The next morning,after cleaning the recess well & shining up just a bit with some emory heat & install the new one. Then have the flywheel clutch surface turned again to get it perfectly flat.
Some good advice above about checking everything over while you have it split. Pilot bearing, throw out bearing, rear engine seal, front tranny seal, clutch disk, & pressure plate.

You can just knock it off easily, problem is when in vertical position on tractor , you don't have gravity working for you when you want to install it. You need to heat it evenly and get it on quick. When flywheel is laying down they just drop into place but on engine you may have to tap it into place. You can just turn them around and use other side unless it is really chewed half way to the other side. They no long bevel the teeth on new ones on either side.

Pete: Thank you. Getting the new one on in the vertical position Is one of my concerns.

Dr. Bert · Feb 8, 2012

Thanks. I plan on replacing the pilot and throw out bearing and buying a new clutch. Hadn't thought of the transmission seal.

Andrew: Thanks. I'm going to give it a try.

Dr. Bert · Feb 8, 2012

Thank you. May end up having to remove the FW.

Mike: Thanks for the "how to do it" tip---Bert

I did the ring gear on my Farmall C without taking the flywheel off. I used a punch to drive off the old ring gear and then heated the new one before installing. As I recall, I had to use a hammer to drive the new one on, but it was not a problem to do so.

Havent done it on an M, but did this on an H: Cut the old ring off, heat the new one in the oven for a couple of hours, (Dont tell the wife), RUN it back to the shop and it may slip on. Now, I left the shop door open all night, it was winter time, and at the time, my shop was less than 10 yards fromn the house.

I would never take the flywheel off to change it.
