Wheel Bearing Removal

<< < (2/2)

gtmdriver:
To be honest, once the old bearings have been removed by drifting on the inner race (which is the only option) I would never re-fit them in case the balls or tracks have been damaged during the removal process.

New bearings are cheap enough to replace as a matter of course.

I also tend to use the ZZ variety with grease seals on both faces.

Chris400F:
Yes, when I think about it replacement is the obvious option. When I started I was working on the recommendations in Mr Haynes's manual about cleaning and regreasing, but realistically that is from 40 years ago and things have moved on since then.
I went for the All Balls bearings as I have read of others on here using parts from them, and at less than £14 for new bearings and seals it doesn't break the bank.
The bearings they supply have grease seals on both sides whereas the ones I have removed have seals on one side only.

gtmdriver:
If they have grease seals on both sides then they obviously need no additional grease.

When you drift them it try to drift on the outer race not the inner. A big socket is handy here, or even the old bearing.

Don't forget the spacer!

Bryanj:
And on the spacer don't forget to straighten out the ears that got bent when you pushed it sideways to drift th so that it sits centrale bearings out

Chris400F:
Bearing kit arrived today. The description of the kit said "All the bearings and seals required to refit one wheel in one convenient package". From the package it seems the same kit is suitable for bikes from the CB/CL 200 through to the CB900 and comes with three different seals, but not the O ring that sits under the Gearbox Retainer on the right of the wheel. There wasn't one at all in the wheel I am working on although there is one in a spare hub I have.

From the Parts List this is P/N 91302-317-700, described as O ring, 53.8 x 3.1. Searching on DS by P/N they seem to show the size as 54 x 2. I know thickness isn't likely to be as crucial as in something like an oil pump but that seems a bit of a difference. Has anyone else been here?
