It looks like there are two different problems in the post.
The 910002 and 910995 are 10,000 machines and covered in the same manual.

heartlandusa,
The wheelbearings cost about 2.00 online and easy to replace. 910995 is the snowblower attachment number of the intake housing assembly. Sometimes they put that number on the lower back base of the tractor section which makes things confusing but I’ve seen it. Regardless if you have a 910995 bucket then the chances are you have one of the 10,000 machines.
For the 10,000 there are two types of axles I know of. One is for differential and the other non-differential. For non-differential the axle is one piece and held in with two roll-pins. One on the right as you look into the back with the machine up in the air. The other is by the support piece by the spur gear. To get the wheels of pop the hub cover off and there will probably be a cotter pin there. Remove that to slide out the tire and hub if they are not rust frozen on.
For the differential type there is a roll pin on the differential mechanism at the left wheel as you look from the back. With that out the left section of the differential will slide out. Then you can remove the right section.
The bearings just get pushed out with taping. You can use a big socket to put on the bearing to tap against.
