WHY do you need to remove the bearings?
If it is just to get the backing plates off - just cut them off.
Cover the bearings with something so you don't get crap in them.
If you need the bearings off to do some mod then to put them back on -
Get new bearings.
And while they are off - replace the outter seal, too.
At the cost of labor to TRY to save the old bearings it is not worth it.
If you have access to an air chisel and a piece of pipe you can do it yourself and save the price of the bearings in labor.
It would take me longet to type out the whole process than it would to do the actual job, so you might ask around, I am sure about half of this crowd has done it at least once.
But here are a couple tips.
The first piece on there is a retaining ring.
It is on there but good.
It is darn near impossible to press off the bearing and retainer w/o derstroying the bearing.
You have to get the retainer off first.
AFAIK - you cannot buy just the retaining ring.
I usually score the retaining ring either by drilling 90% through it or cutting it with a Wizz Wheel (Depending on the mood I am in) then push it off with an air chisel. Then the bearing usually comes off fairly easily.
BE VERY CAREFUL YOU DON'T NICK THE AXLE SHAFT!
Yes, you will destroy both the ring and the bearing this way, but you will be putting on new bearings.
Now - what was your question?
