Wheel bearings

[sbadvm]

Hi,

Had the bike MOT'd yesterday and had an advisory on the rear wheel bearings.Can anyone point me in the direction of cheap but good quality bearings that they've used themselves and would recommend?

The tester said I needed two for the wheel and one for the sprocket carrier?

Thankyou.

For the rear wheel I picked up two of these

130-63032RS

The part # for the sprocket carrier I don't know, but I do know there is a bearing in there.

That's quite spooky! I took mine for her MOT today and she failed on the front wheel bearings. I have a set in my toolbox that I picked up cheap when I bought a set of fork seals but I didn't get dust seals for the bearings.
Wemoto have a complete set including seals for £18.17 delivered so should have them in a couple of days.
I have the PDF manual printed out and a Haynes basics techbook, the procedure looks reasonably straight forward but if anyone has any advise on removal and re-installation it would be greatly appreciated
Many thanks, Phil.

Chilling the bearings just b4 installing helps.....leave bearing in protective package or clean new freezer bag b4 puttingin freezer.

Main method i use is when starting use a drift and get it on the inside lip of the bearing from the inside/otherside and hit it with a hammer and move 90 degrees every hit till it comes out. give everything a clean and then place new bearing in and tap it in evenly making sure that it seats properly then put the spacer back in and do the same for the other side bearing

Thank you gentlemen. That's almost exactly as described in the haynes book, except they suggest gently warming the area around the bearings prior to installation, as I don't have a heatgun, the freezer idea works for me!
Once the new bearings arrive I'll bang 'em in the freezer and hopefully get the new ones in over the weekend. I'm assuming a small amount of grease is advisable but any suggestions regarding the type, mineral, teflon etc?

I highly recommend using a brass drift if you can get one and EXTREME CAUTION. Bang them our evenly or you will severely gouge the soft aluminium that the races sit in. Have a look with a magnifying glass if you have one and a good flash light,  at the area where the bearings sit and look for any cracks in the hub. I had to replace my front wheel when I did my bearings last year as I found a hairline crack hiding under the bearing after I removed them.

When you go to put the new ones in, if you have a socket that is the same size as the outer diameter of the bearing, place the socket over the outer bearing race and tap it in using the socket. It will help put it in more evenly.

Thanks for your advise Dave, I'll see what I can find. Fortunately I actually have a spare pair of wheels that are in better condition than the ones I'm using, they need painting before they go on so I'll change the bearings on this front one first just in case!

Last wheel bearings I did, I ground the old bearings on the bench grinder until they easily slipped in and out of the seat, then used a long bit of m16 threaded bar to draw the bearings nice and square, with no risk of damage as driven in using 100% perfect drift an no impact. Perfick.

Similar idea to how Mr Haynes suggests doing steering bearings.

Front wheel bearings done, actually very straight forward. Probably took little more than an hour start to finish! 
Many thanks everyone for your suggestions.
