Well, I blew a rear wheel bearing while at Homecoming. Not usually a big deal, pull the bearing, replace the bearing. Had the proper collet-style puller, but when I started to pull, the inner race broke, leaving me nothing to pull on. The INSIDE diameter of the outer race is a larger diameter than the wheel hub, so I can't pop it from the back without doing some carving on the wheel.  I really don't want to try and wobble it out by banging on things and "walk" it out and FUBAR the bearing housing on the wheel. I have one idea, but am interested in seeing if someone has something quick and effective.} (Message edited by steeleagle on June 10, 2016) (Message edited by steeleagle on June 10, 2016) | ||

Heat? | ||

I tried heat, but with nothing to pull on (any puller slides right out of the race) I can't get enough force onto it...yet. Plus the aluminum hub pulls heat away so much quicker, the steel race stays hot and expanded, just making it tighter. | ||

...and the only access to a pulling surface is the inside of the outer race. Not a lot to grab onto. If I had a collet big enough, I might be able to expand it to snag the inside of the race, but... | ||

Weld a large washer to the outer race than heat up the hub. Using a long drift or pipe knock it out from the other side. That what we do in the shop. | ||

Ditto what Lance said. Heck, if you just weld a bead on the inside of the old bearing, it may just lift right out. The bead shrinks while it cools and pulls the bearing in. Al had a really nice post going into great detail on how to really do it nicely. I did it much less meticulously for a friends Kawasaki quad that had the same problem, and it still worked great. | ||

It is a common practice to put a quick bead of MIG weld all the way around the inside of the race and flip the rim over. It should fall right out. Work quickly or you may need to help it out. | ||

after you get the bearing out do this a long screw driver will work good   | ||

Well, I welded a washer to the inside of the outer race to push/pull the stinkin' thing out. As I was attaching the puller, the bearing race almost fell out on its own. It took only a little more provoking to get it out. Not sure if it was still that hot from the welding, or if the bead I made collapsed the race, but I don't care. The S.O.B. is OUT!! The new bearing is sitting in the freezer. Thanks for the tips. | ||

Put a thin film of grease on the outside of the new bearing to make it easier to get out the next time. Warm the rim a little with the sun, a hair dryer, or a heat gun, and the new cold bearing will almost drop in. | ||

Excellent! Its nice when physics actually work for you instead of against you. |
