Rear Bearings
 

My rear wheel seems to be seizing slightly when running for 30 mins. I've taken the rear caliper of and slacken the chain and the problem seems to be coming from the hub. I'm assuming that the rear bearing are shot! How easy are they to change? Any special tools needed?

:puzzled:

Have you had a new rear tyre fitted? When they put mine on they put the dished washer the wrong way round. Lucky noticed straight away as wheel was not turning as free as it should.

No,

Tyres were done last year
Thanks anyway

Not too difficult to get out using a bar as a drift through the hub, a bit of heat on the hub before replacing them helps too. But if you're not sure I wouldn't think a dealer would charge much to do it, especially if you just take the wheel.
Also with the wheel off it is usually easy to tell if the bearings are shot.
One other possibility, are the pads moving freely in the caliper - is the disc hot when this happens.

Not difficult to change actual bearing, but you'll need to support the bike at the engine, or suspend it so you can remove the hub. Apropriate sized drift will get the old bearing out. I don't think Ducati supply the bearing separately from hub, but you can get them from bearing suppliers for around £25.

I thought the bearings needed to be pulled into position!

The bearings are in the hub, not the wheel.

Ducati don't sell the bearings, only as part of the hub. (£300 ish!)

Anyway, drift out the bearings and get the numbers off the side of them and get youself down to a bearing suppier near you. www.yell.com.

The haynes manual states that the bearings need to be pressed or drawn into position but I used the old brearing to drift them back into place and they seem to be fine.

You could make a puller using a treaded bar and some thick flat steel if you want.

Put the brearings in the freezer overnight as this makes them a wee bit smaller and easier to install.

Do a search for rear wheel brearings under my name as I posted the numbers you need to give to the brearing supplier.



:roll:

Thanks!

The parts are available individually from Ducati - see attached pic.

Admittedly this is from the 748RS cat but as the 748RS uses the same hub/axle as the road bike the bearings etc should also be the same. Get your dealer to cross reference the part numbers before ordering though just to be sure. Their parts system should be able to tell you what other models any given part fits.

Hope that's of some help.
