Maybe I am not seeing something. Most machinery that i have worked on in factories, have a spot in the casting where you can get to the inside of the groove and start prying. Is one there that I don't see? Because unless you can get behind that snap ring to pry against, I don't see how it is possible to pry it out.

Fred, are you and I talking about the same snap ring? The one I am asking about fits in a groove between the bearing race and the seal on the inside end of the short pinion shaft. The bearing supports the pinion shaft right next to the brake drum. (right side of tractor) and is between the race and the seal.

Well, I got the snap ring out, but we sure twisted it getting it out. I picked up new bearings and seals and a new woodruff key but will have to go to Agco in the moring to get a new snap ring.
I am concerned about the shims that i am supposed to put on the end of the pinion shaft under the cover. I suppose I just need to pick up shim stock and make what I need.
The housing has been cleaned up and if it doesn't rain tomorrow, I am going to start putting it back together. This is an outdoor project. The snap ring was the hardest part to remove. It wouldn't even move in the groove. I frist tried some Gibbs penetrating and kept hitting the ends with a screw driver. Finally, I decided to use the torch and heat it up. After it cooled some, tapping started it to move. Then we could move the race a little to give the snap ring some room to get a screwdriver under it. When we got it out is was a spirial by about an inch.
Whew, Ever notice that the darn engineers still haven't learned to make things easy to work on?.

you dont have to take the snap ring out. it acts as stop so the seal dosent go in to far and so for bearing cup. push the old cup out with a long pin punch in stall new cup the same way the bearing stas on the shaft. the seal gos in from the trans end of the housing the bearing cup from the wheel end dont cut seal with the woodruf key when putting shaft back in
