What seems to be the problem? How are you going about it?

There isn't much to it. Get in there with a long punch or screwdriver and knock them out. You might have to push the spacer off to the side to get enough purchase on the inner race. Also move around the race taking a little bit at a time so the bearing doesn't get "cocked" in the seat as it comes out. It helps to heat the hub around the bearing to expand the alu. and it might take a pretty serious whack to get them moving.

My Ducati actually has a notch in the end of the spacer to fit a "special tool" which is nothing more than a piece of bar stock with a knob machined on it to fit in the notch. In my experience a screwdriver works fine. I did grind the tip to an angle so the thing contacts the race at more or less 90 deg.

Like mentioned above, you can heat the alum hub at the bearing area. I've used a propane torch for this. I also just use a 12" piece of 3/4" round stock just because it's easier to hold in place for me and it's heavy enough to bang the internal spacer out of the way. Another thing I do is to use a magic marker and put 2 marks on the hub 180 degrees apart so I know where to hit the bearing without getting it cocked. Once 1 side is off I use a puller made from some large washers and threaded rod. I use it as a slide hammer. Use the same device to install the new bearings.

Here is a tech article that I did on the rear wheel bearings. The front are similar except there is no retaining ring or double bearing on one side. The procedure is the same though.

Throw away your claw hammer and get a 3lb hammer. Then find a decent 5/8" (or bigger) drift punch or something suitable. You lose all of your power with a skinny punch. You will be amazed how easy it is with a good hammer and punch. And like cal_tony says, mark the bearing or pay attention because if you get it crooked as it comes out it will feel like it is welded in place.

Get a bigger screwdriver... really... it's just a typical rubber seal. Thin metal with rubber bonded to it. It doesn't take much to pry it totally out of shape. Don't bother trying to save it. If you're after the wheel bearings you'll need to replace the seals too.

Not sure what your asking for. If you want to know the size of the bearings, they will be stamped on the bearing. I think the FSE uses 6905 on the front 25mm x 42mm.

That washer HAS to go between the two bearings in the proper orientation or you will bind up the bearings when you tighten the axle. It should be pretty obvious to you which way to flip it if you didn't note it on disassembly.

I would just replace the seals. They are not that expensive.

If you have a couple days just order the bearing kit from Go Fasters. In my experience it was quite a bit cheaper than buying individual bearings from a bearing shop.
