Wolverine Differential Wheel Bearing Problem
#1
I have a 98 wolvy that has the outer race of the bearing stuck in the differential case. Anyone have any idea of how to get it out? Really could use some help on this one!.

mine was a real booger too. You have two options.. I got lucky and ended up with the latter of this, but started out with the first...
Here is option 1. If the bearing is still in one piece and the differential is still on hte bike, with the axle removed, use a piece of steel that is long enough to reach through and punch the bearing from the back side. Be careful not to scratch up the inside of the diff. I highly recommend a piece of pipe that someone on the otherside can hold in place by sticking a screwdriver through the bearing and into the pipe. This will insure alignment with the bearing. Make sure to drive it around the bearing.. do not continually smack it in the same spot. You can also apply some heat to the diff case with a propane torch. But don't get it too hot.
The other alternative involves buying a nice bearing puller attached to a slide hammer. I was lucky and had one at work. The puller I am talking about has two fingers that go inside the bearing. The slide hammer shaft is turned which makes the fingers expand and lock in behind the bearing. Then you can use the slide hammer to do the pulling.
I hope this helps. Either way, I would recommend doing it with the differential in the bike. It makes for less items to hold still.
Good Luck.

I hate it when cyberspace eats a nice long post.
Trial 2
After writing all that, I re-read your post and you said the outer race is stuck. IE the bearing is not in one piece.
Here is my suggestion..if you still have the ball bearings and the inner race, reassemble the bearing. This will take time and patience, but will be worth it. Using some grease to hold the ***** in place, put them in one at a time and put the inner race in last. Or at least get some of them in place and then hold the inner race in place until you get the last couple ***** added. Now, carefully space the ***** out so that they would be in the place where the carrier would have held them. now, using some rolled up duct tape or the like, make some spacers to hold the bearings apart from each other. The last one should go in tight. This will keep the inner race in place so that you can proceed with step one of my previous post.
Why do I know about this.. Ah Ha... Experience.
Good Luck.

I have had alot of luck using a stick welder to get stuck outer races out in rear bearing carriers on sport quads. assuming the diff case is aluminum and race is steel its nearly impossible to weld the two together (aluminum conducts heat so fast it wont take, with a stick weld). I run a nice ridge all the way around and build up 2 spots to get a good land to whack from the opposite side. Once its heated by the welding it almost totally releases from the aluminum and comes out pretty easy.
The stick welder also works awesome on large broken bolts in aluminum (like swingarm skid bolts and the like), heat up a little puddle on top of the broken nut or stud and dab another similar sized bolt on top then weld them together, takes a little patients but once the weld hardens the bolt will come right out.
ofcourse I am assuming you have access to a stick welder, they are fun and cheap too! all purpose tool! just dont get welders flash (it sucks!!)

95 Wolverine and Warrior 007 pretty well got ya covered on getting it out. The only thing I can add is the extra set of hands always helps and mine were a bi7ch to get out too!

Afriend of mine took the diff. home with him to drill out the race, I hope it works without messing up the carrier. Thanks for the input. If the Diff gets messed up, does anyone know where I can get one for a reasonable price?

I'm a little confused on the race deal...mine had one bearing that was one piece...the bearing and race were made together. How I got mine out was a long bar in from the opposite end...I've only replaced the outer bearings...I know there is a third bearing...But its inside and has never went bad on mine. I guess the bearing could be so bad that it came apart. Let us know how it works out.
