tagy 1 Posted December 9, 2006 I got a new bearing pressed into a hub, but the old splined part was too worn to reuse. I had a spare hub so knocked the splined part out of that to put in the new bearing. However part of the bearing is stuck to the splined part? how can I remove it? or is it a garage job?

Tidy_Andy 0 Posted December 9, 2006 i carefully take most of the material away with an angle grinder an then spilt the remaining part with a cold chisel. Share this post Link to post Share on other sites
sonofsam 5 Posted December 9, 2006 The splined part you talk of is the hub, the bearings get pressed into the hub carrier:) I would try a knife edge puller on that, before you resort to an angle grinder! Share this post Link to post Share on other sites
lagonda 41 Posted December 9, 2006 As the bearing race is very hard it will also be very brittle. This should mean that a sound whack from a club hammer and old chisel at right angles to the edge of the race will split it. The hub itself will be softer so wouldn't be damaged. Another method: it may not be obvious because of dirt, but the outer edge of the race (ie the face touching the flange) will be radiused. You can use a knife-edge bearing puller on this, or use a hammer and old flat screwdriver blade: hold the blade in the radiused area & tap firmly, repeating on alternate sides. DON'T keep hammering away on one side. Once you see daylight beginning to appear between the flange & bearing, you should be able to lever the components apart with a couple of large flat bladed screwdrivers.

j_turnell 134 3 Cars Posted December 9, 2006 Often had to use the grinder when ive done it before, or cut two grooves in it so the puller has something to grip on too. Share this post Link to post Share on other sites
tagy 1 Posted December 10, 2006 (edited) cheers people, got it off after attacking it with the grinder.. put a small nick in the hub but I think thats ok, just a bit of a scratch. Now do you think I can hit the hub into the bearing myself? the garage will do it but that would be next week. Edited December 10, 2006 by tagy Share this post Link to post Share on other sites
Tidy_Andy 0 Posted December 10, 2006 I cant see the problem with using an angle grinder so long as you dont damage the hub itself. Which is why i always split the remaining part with a chisel. A small surface graze wont cause you any problems IMO. I wouldnt suggest beating the hub into the bearing with a hammer. Its the sure fire quickest way to knacker a brand new bearing Either push it into place with a vice and a socket on the inner race or if your unsure take it to another garage. Its a 30 second job for them. Share this post Link to post Share on other sites
