Seal is leaking on the control shaft on an Eaton 10.  SM says to use a "standard puller" to pull the control arms off the shaft.  Yea right !  Cannot buy a puller with jaws thin enough to go between the case and the arms.  Only about 1/16" to grab on to and less than 1/4 between the arm and the case.  Got puller jaws down thin enough to go in and hook, and it broke the hook off the puller arm, just like I figured it would.  Down to 2 choices: [1] put up with the leak or [2]  get a bar and a big hammer and drive it off - which the SM says not to do.  Drive it off an take a chance of ruining the hydro.  Putting up with the leak is the better option I think.  At least the tractor will do the work, just have to add fluid to keep the tank full.  Somebody had a big brain fart when the designed this set up.

Any chance of getting a bearing separator in there and using a puller on that?

Not really.  This is from the right hand side.  Arms go out the Left side about 3".  Snap ring on top of the arm take up space for any puller to hook.  This shaft in center of the hydro and on the very front.  Points down - photo is right side up from the RH side of the tractor.  SAM_0358.JPG   The nut is jut on there for the puller bolt to center on, not holding anything.

Looks like a tough job. How about a small grinding stone on a Dremel tool to get part way through the snap ring on the side opposite the ears, enough so you could break it or spread it off then pickle fork.,

Could you maybe remove the retaining bolt,  weld a nut (for a bolt almost equal to the size of the shaft) onto the lever, then just use a bolt to push/pull it off.  After removing you could cut the nut off, or just leave it for the next time and simply use a longer retaining bolt.

If you run out of alternatives you could look for replacement arms, then cut the old ones off with a with a saw or grinder. Don

I understand that is a tapered shaft & key.  No retaining bolt.  Just a large nut & washer on the shaft to hold the arms on.  I gave up and put it back together and will live with the oil leak.  Dirt floor in the machine shed so if I forget to throw a paper feed bag under it won't hurt anything.  Some times a job just isn't worth the trouble and oil is the better of two evils.  I appreciate the suggestions and would like to hear of anyone who has replace that seal without tearing down the hydro.  Nothing wrong with the hydro, just that seal is leaking.
