j0hn Posted March 21, 2013 Share Posted March 21, 2013 Riding on the motorway and my rear wheel bearing thought it was the perfect time to go. Guess it's time to replace them so I managed to get the one that didn't brake off first. Having issues with the one that did go, it's really stuck in there. Can't seem to get the bearing housing to catch when trying to push from the other side. As you can see from the picture below, the end with the stuck bearing is completely flat/worn away so I'm not able to drive it out. Looking at it through the other end (where the first bearing was and taken out first). Anyone got any ideas on how I could take this stuck bearing out? Thinking of maybe cutting/drilling two sides but I'm worried that it could damage the hub. Link to comment Share on other sites More sharing options...
dt502001 Posted March 21, 2013 Share Posted March 21, 2013 Warm up the hub lightly( heat gun or carefuly with a torch) the alumi will heat way faster than the steel bearing race and quickly drive out the old bearing race,more than 2 hands will make this easier. 2 to warm and hold and 2 to drive it out. or lean it against a bench . It DID not just let go it's been going for a while half the bearings are gone,lack of maitence,greasing and new seals about 6 months ago was in order.

j0hn Posted March 21, 2013 Author Share Posted March 21, 2013 The problem is, I am unable to drive it out because there is nothing to catch at the back end of the bearing housing. Seems to have disintegrated while attempting to drive it out. What else could I do after warming up to get it out without damaging the hub? I greased up the spindle a few weeks ago but that was about it for the maintenance in that area. I'm not sure how else to grease the actual bearing, do you break the seal, grease it and reseal it? I wouldn't have thought it would be possible to reseal the bearing if the seal has been broken. Link to comment Share on other sites More sharing options...
Grouch Posted March 21, 2013 Share Posted March 21, 2013 John what happened when it went? How fast we're you going? The same thing happened to me and it was scary shit, I nearly lost control with the back end sliding and bouncing. Link to comment Share on other sites More sharing options...
j0hn Posted March 21, 2013 Author Share Posted March 21, 2013 Was doing about 50ish. I just heard a sound, didn't really feel the back end pulling side to side. Got worse as I was coming up to my house and started hearing screeching noises. Stopped at the side to check and lo and behold, the rear wheel was shaking side to side. Ended up pushing the bike for about half an hour to my house . Link to comment Share on other sites More sharing options...
dt502001 Posted March 21, 2013 Share Posted March 21, 2013 well what I woud doo is to weld a washer to the race of the same ID size if there is absoutly nothing to hit,but looking at the pic at 12 -4-7 looks like there is a very small area of the race that with a sharp punch you could get a bite,punch about 3/16 in round will give you a better angle to get at the edge of the race.

KirriePete Posted March 21, 2013 Share Posted March 21, 2013 Got a Dremel? I would use the mini disc cutter to slice through the stuck race at a couple of places and it should just pop out. If you catch the hub with the cutter it won't be the end of the world, but try not to do more than scratch it, although a splash of Loctite bearing fit can cover any "Ooops" issues.

Grouch Posted March 21, 2013 Share Posted March 21, 2013 Your lucky mine just went all of a sudden with no warning. It's only £12 for a set of decent bearings. Link to comment Share on other sites More sharing options...
dt502001 Posted March 21, 2013 Share Posted March 21, 2013 Don't cut it out with a dremal you will never get to the inner part of the race without cutting into the hub. If you have no means to weld in a washer take it to someone who can, the race will almost fall out after tack welding in a washer,as the weld cools the whole thing will shrink in size. Just get a washer bigger than the id of the race and smaller than the OD Link to comment Share on other sites More sharing options...
Moderator Airhead Posted March 21, 2013 Moderator Share Posted March 21, 2013 I'd do as dt said, take it somewhere to weld something to it that you can hit Link to comment Share on other sites More sharing options...
j0hn Posted March 21, 2013 Author Share Posted March 21, 2013 I've still to try the heat gun on the hub method, if that fails, I'll just take it somewhere and get a washer welded as dt suggested. Thanks! Link to comment Share on other sites More sharing options...
Grouch Posted March 22, 2013 Share Posted March 22, 2013 Just take it to a garage and get it sorted properly, you really don't want to go through what I went through. Link to comment Share on other sites More sharing options...
j0hn Posted March 22, 2013 Author Share Posted March 22, 2013 Heating the hub didn't work. Took it to a motorcycle dealer and popped it out for me at no cost. I'm jealous that it took the guy less than a minute when I've spend almost half a day on the thing! Link to comment Share on other sites More sharing options...

j0hn Posted March 22, 2013 Author Share Posted March 22, 2013 The mechanic took it inside to his workshop so I wasn't able to watch. I can only assume he used one of those heavy duty bearing puller tools because there was no way to push it through from the other end. Thanks for all the help guys, new bearings are in place!

Grouch Posted March 22, 2013 Share Posted March 22, 2013 That's why sometimes it's just best going straight to a garage, unless you have your own workshop complete with specialist tools. Link to comment Share on other sites More sharing options...
dt502001 Posted March 22, 2013 Share Posted March 22, 2013 Na he just has the right punch to hard to explain how to make .I made myown and it only gets used for wheelbrngsto catch that small lip. But it done and you saved all the expence and tried yourself gained some experience unlike some people not mentioning names LOL if the bearing hadn't been so bad it would have come out like the other side did.Live and learn. Now don't over torque up the axle bolt that kills bearings. Link to comment Share on other sites More sharing options...
j0hn Posted March 22, 2013 Author Share Posted March 22, 2013 I tried to make my own but it just wasn't bent enough to catch that small lip. It would catch just at the end of the lip but as soon as you strike the end with a hammer, it slides off. And yea, the axle bolt isn't on too tight, thanks for this tip! I'm glad I attempted to do this myself and I'll know how to approach it next time . You mentioned greasing and new seals as maintenance for the bearings. How do you go about doing that? Do you take out the black seal (picture above where JAPAN is printed), grease it and put a new seal on it? Would this new seal fit in without any issues? Grouch, I've got my fair share of tools in the house but nothing to tackle this job specifically. I was hesitant going to the garage for this because it doesn't usually pan out as you planned. It was a different dealer (closer to home) from my usual place and was glad the guy did it for free. I'm thinking of adding a bearing puller to the tool collection, doubt these will get used much but at least I've got it in-case I or someone else needs it. Anyone know if this set on Amazon is suitable for such jobs: http://www.amazon.co.uk/Silverline-783172-Puller-Bearing-Separator/dp/B000WTLOIG/ I think that set is exactly the same as this but less expensive, probably because it's not Silverline branded: http://www.amazon.co.uk/Blue-Spot-Puller-Bearing-Pieces/dp/B005N78UN4/ Came across these too but they look a bit weird lol: http://www.amazon.co.uk/Silverline-MS23-Piece-Gear-Puller/dp/B000LFVPYE/ Link to comment Share on other sites More sharing options...
Moderator Airhead Posted March 22, 2013 Moderator Share Posted March 22, 2013 its already greased leave it alone or you'll spoil the seal Link to comment Share on other sites More sharing options...
j0hn Posted March 22, 2013 Author Share Posted March 22, 2013 Oh I didn't mean grease it now, I meant as maintenance for the future. Was referring what dt said earlier on in this thread. It DID not just let go it's been going for a while half the bearings are gone,lack of maitence,greasing and new seals about 6 months ago was in order.
