rex a. lott Posted May 24, 2004 Report Share Posted May 24, 2004 I have been trying to remove the rear wheel bearings for replacement. I can not figure out on how to get them out. If anyone could help with some sugestions or tools it would be a big help. Quote Link to comment Share on other sites More sharing options...
wonder boy Posted May 24, 2004 Report Share Posted May 24, 2004 You get a socket that fits just around the out side of the bearing. You keep hitting it and this will force the other bearing at the other side out, there is a long thin metal tube inside the rear hub so catch that. You then put that socket you have just used on a long rod and put it inside the hub and nock out the other one. Gavin Quote Link to comment Share on other sites More sharing options...
t-shock 250 Posted May 24, 2004 Report Share Posted May 24, 2004 For god's sake don't do that!!! The bearings don't float in the hub, they are seated in place and can't be hammered straight through! Quote Link to comment Share on other sites More sharing options...
munch Posted May 24, 2004 Report Share Posted May 24, 2004 fully floating wheel bearings wonderboy stick to what you know best! what is that????????????? Quote Link to comment Share on other sites More sharing options...
bigfoot Posted May 24, 2004 Report Share Posted May 24, 2004 I know this is not how it should be done but I once had a problem getting some very old wheel bearings out of a Beta wheel and resorted to welding a big nut on to the bearing that gave me something to hit from the opposite side. This knackered the bearings but they were knackered anyway so who cares. I would do this (and did) only as a last resort but it worked no problem.

trialscot Posted May 24, 2004 Report Share Posted May 24, 2004 The safest way to avoid any damage is to get a light engineering shop to turn up a double-diameter (shouldered) steel drift to fit inside the alloy spacer and inside the bearing. You should be able to get the dimensions from the bikes importer. Then check to see that there are no circlips holding the bearings in place, it's not so common now but I think Technos have them for instance. Gently warm up one side of the hub round the bearing seat and use the drift to drive the bearing out . The other side is now no problem as you have lots of room to work on it. If you can't be bothered to do it properly you can just use a socket or bar to wallop out the alloy spacer and the bearing, again after warming the hub. You'll definitely mash up the thin end of the spacer but if you're very lucky you might be able to dress it up with a file for re-use. And take careful note of t-shock 250's post!.

kevin j Posted May 24, 2004 Report Share Posted May 24, 2004 then after its apart, cut some notches on one end of the spacer, aobut 1/2 wide and 1/2 inch deep, or drill a cross hole through the spacer someo where along the way. next time at least, you have something to use a drift punch on to get them out. k Quote Link to comment Share on other sites More sharing options...
rex a. lott Posted May 25, 2004 Author Report Share Posted May 25, 2004 Thanks for all the tips. I used the method where I welded a piece of metal to the inner race and drove the bearing out. It worked great. I have a SKF bearing cross referance for you all. The SKF # is 6004 2RSJEM for rear wheel bearings. Thanks Again Rex Quote Link to comment Share on other sites More sharing options...
bigfoot Posted May 25, 2004 Report Share Posted May 25, 2004 I'm glad it worked but don't tell anyone it was my idea. Quote Link to comment Share on other sites More sharing options...
griffiths of wales Posted May 25, 2004 Report Share Posted May 25, 2004 sounds like some of you have complicated the process slightly....I use an old blunt screwdriver and tap out the bearings from the opposite side of the wheel, making sure that the bearing is pushed out uniformly by tapping evenly around it's periphery. Takes a bit of skill with the hammer but never fails....honest Quote Link to comment Share on other sites More sharing options...
trialscot Posted May 25, 2004 Report Share Posted May 25, 2004 Sounds like GoW may not have seen the fragile alloy spacer on the Monts rear wheel?. Quote Link to comment Share on other sites More sharing options...
griffiths of wales Posted May 29, 2004 Report Share Posted May 29, 2004 Well aware of the spacer, there is enough of the bearing shoulder (inner race) to give access to a 'blunt' screwdriver. With a little skill, no damage is done. Quote Link to comment Share on other sites More sharing options...
bob abell Posted May 29, 2004 Report Share Posted May 29, 2004 20mm ground shafting from "Metal Supermarket" about 200mm long with square sharp edge on one end Warm the opposite hub a bit with propane torch Tap the sleeve and bearing out with the shafting Pop the seals off your new bearings (6004-2RS, not 6004-ZZ) and fill with grease. Replace the seals Tap bearings in evenly on the outer race with a large socket Done, 5 minutes later Quote Link to comment Share on other sites More sharing options...
