problems removing snap ring / circlip / retaining ring

[joecdeere]

LeeJohn nailed it, I have several Allis tractors and that pair of pliers and a thin screwdriver will take them out with some work.

boggen - the tool that leejohn shows is what I have and exactly what you need.
The jaws open when you squeeze the handles to expand the ring.

In some cases, the trick is that you don't want to remove that snap ring - you just need to expand it enough to get it out of the groove in the shaft.
Then you should be able to slide the rear cover off, over the end of the shaft, or slide the shaft out from under the snap ring.

I had to do a similar job to take a manual gearbox apart on an old Volvo - that's when I bought those pliers.
Took me awhile to figure out that the dang ring wasn't coming off without something getting broken, but if I could get it out of the slot, all the gears & the shaft would come sliding off under their own weight (like a freight train that's run out of track & onto the concrete floor)!

You should be able to get those pliers at NAPA or similar - worth a try?

Did you get it out?

What some people are missing is that this is an INTERNAL snap ring. It won't come out by expanding it.

Using the OP's diagram in post 10, I added some arrows and text showing how I have removed this type of ring.

never did get the snap ring out. i got to budge with the one tool were i could almost get something in behind it. then i fudged the one good pry end of the snap ring i need to get the snap ring out.

here in a bit will be ordering entire piece (pto casing), pto rod, 2 gears, and a drive shaft out to the pulley for the belly mower. i saw 3 last week, 2 on ebay, and 1 i think i craiglist. will just order entire thing. and be done with it. tired of fighting it. will work on it this winter. after i get other entire rear end, on tractor and grass mowed. grass is getting about knee high now.

and to note it, the one tool almost got me to your image BCP, but just would not give it up, so close, so so close, and then fudge the pry snap ring were i could pry.

I see you are near Peoria. Boy if I was still in Rockton I would of come down and see if I could of helped. Sure would of love to give that a shot.

Have you tri and push on one end to push it off from the shaft ? like in a sircular motion ?

Don't waste your time with pliers or punches, you'll lose your mind. Go to HF and buy a small 1/8" pencil grinder with a tiny cut off wheel. Cut through most of the way and fold it in half.

I think this is the best idea so far, you need to pry it out from the inside and up,, with a small screwdriver...
then the rest should follow if you add another small screwdriver at the top working your way around until it snaps out.

For those snap rings I use a flathead screwdriver specially ground. And it needs to be a larger, and higher quality screwdriver. Guys that work on automatic transmissions know all about them snaprings.

The screwdriver will look like this
