I would get new O-rings. You will be taking a lot of stuff apart in a rebuild like this, and a few extra dollars for any O-rings, etc., may keep you from having to go back into the unit to stop a leak. When I rebuilt my front end, I got extra small parts, and replaced all the O-rings and bearings, etc., while I was in there. I have several usable parts left over, but the way things go for me is if I have extras on hand, the chances are, I won't need them. However, if I try to cut corners, I usually have to redo the job. When I blew the front axle, the dealer shot me a price of about $1800, and I spent about $650, so I'm still way ahead.
If you don't have a factory service manual, you might want to get one....I think I paid about $80 for mine. Living out in the boondocks, I hate to take anything to the dealer which is about 40 miles away, if I can avoid doing so. However, if you have a parts breakdown, that should get you pretty close. About the only thing you might have to be concerned about are any clearances in the bevel gears.
I noticed some references to using RTV when putting things back together, and I would agree. I like to use the Blue RTV that is sold for use in water pump rebuilds, etc. It forms a good seal, and never really hardens, so it won't create a problem if you have to go back into the unit again. Use just enough to coat the O-rings, and mating surfaces, without any excess getting into the lube.
Also, after you get the bad side fixed, it probably wouldn't be a bad idea to take the other wheel off, and clean the other side real good, and look for any evidence of damage or cracks on the other axle. You might even put the tractor on stands, fire it up, and have someone run the HST, while watching the axle closely....looking for any wobble, etc.
Just take your time, and you should be ok....it's not that hard for someone who has a set of metric wrenches/sockets, good mechanic skills, and some patience.
