Rear wheel bearing failure

[Alba]

Going into work this morning bike did not feel right, on the way back took it real easy. Back wheel off and found the left side bearing completely fecked

Really could do without this at the moment. Any tips out there? Wemoto has the rear bearing kit, kit here should I also replace the sprocket carrier bearing, here. Haynes manual not that explict about how the left side bearing can come out without taking off the spocket coupling. Ahhhhhhhhhhhhhhh

I'm not an experience DIY mechanic but willing to give it a go, or should this be put into a garage?

I had my bearings done at the garage (as I found out there was a lot of play during the MOT and didn't fancy riding it home like that then waiting for days for parts to arrive to do it myself) and it wasn't too expensive. About £45ish I think including the price of the bearings, though they also nipped up the steering head bearings for me at the same time too.

Next time I'll have a go myself and catch it earlier though as it doesn't look like a hard job and bearings are fairly cheap.

There's a video tutorial on the Garage Night site (where they replace the bearings on an Africa Twin) and a step by step guide in the wiki on this site too I think. They make it look fairly easy.

I'm not sure if you should be replacing the sprocket carrier bearing too (I'm very inexperienced mechanically too), but I'd be tempted to replace the whole lot myself while the wheel is off as the bearings aren't very expensive and replacing the lot will presumably mean they last longer until you have to do it again. Not sure though.

I would replace the carrier bearing as well while the wheel is off.

The Garage Night showed me how to do the chain and sprockets, ended up using the angle grinder technique. I really like them, thanks for the prompt

That is what I was thinking, the only point putting me off is the Hayes manual is not to good on this one.

By the time I get it to the garage they order the parts etc and I pick it up I should give it a blast. Nothing ventured nothing gained

Wish me luck, I may be some time

No worries. Good luck

The luck has run out

As you can see from the picture below the bearing which failed has completely disintegrated and left the outer shoulder in the hub. I have no bearing inner shoulder, therefore nothing to hit against to get it out. I cannot get any purchase on the bearing from the other side of the hub. Any suggests how to remove the last bit of the bearing ??????????????????

Can't quite see, but if there is any part of the shoulder proud of the hub when accessing it from the other side, it should be possible to tap it out with a long, thin chisel, or even a beefy screwdriver. Wider edge the better, ie about 1.5", so that you have the chisel on the bearing on 2 points for better pressure. I have done probably, hundreds of bearings in my time, quite a few on dirt bikes that used to eat them until I discovered a supplier of proper sealed bearings This is my usual technique, crude but effective. Place the hub on a big flat piece of wood to take the shock of the impact.

I have also used various types of drifts to tap a bearing free when the inner is missing IF the outer is accessible, a large socket is a fave, although it can be hard on the hammered end!! I have a home made 1/2" end to put in the socket bar for hammering!!

Where no purchase at all is available, you will have think cutting which will effing hard! Boiling water can give you a spot of variable expansion on the hub to allow the bearing to drop away, but i suspect not in this case?

EXTRA...

It may be that you have to knock the other side bearing out if there is a spacer shim, as that will the allow access to the buggered side. I cannot recall what is in there on the 'alp.

Good LUck!!

If you can do as above then fine, if not try a chisel of similar on the side to get the case turning if you are careful you may be able to crack it and then get a purchase to remove it, blowtorch it.

That will come out easily with a slide hammer and adapter, but if you don't but if you have got one and they're about £70 to buy put a grinding bit on the end of a dremmel or a drill and grind it out once you've gone through the outer shell it will collapse on itself and you can use a screwdriver or lever to work the rest out

steveR, I have no shoulder at all, so it will have to be StumpyFinger's chisel or get a grinding bit for the drill no dremmel or slide hammer jasonbc

One more shot at it tonight

I appreciate the responses least it give me something to try
