retro fit rear rim from 2008yz450 to 2009

[shubytbird]

Need to find a bearing kit that will allow me to use a spare rear rim from my 2006 yz450 on a 2009 yz450. The 2009 uses a larger diameter axle bolt and it appears to have a different hub so just jetting bearings from a 2009 won't work.

anyone done one?

Shuby,

Do you have a bearing supply house near you? I'm thinking you could take your hubs and axles in and they should have a bearing that will fit the O.D. (outside diamter) for your hub and I.D. (inside diamter) so it fits your axle and you should be good.

This has been tried without success. No one seems to make the required bearings.

Gray,

Any chance of a bearing/drives place making the bearing or would the cost outweigh the cost of just buying a new hub?

Shuby,

Have you looked on ebay or craigslist or a like source for a used hub rather than buying new? Might save you a few bucks and the headache of trying to retrofit bearings to the other hub.

There is not a practical way to do this as far as I know.

The only structurally sound way to address this that I can think of is to make up a set of steel sleeves with a 25mm O.D. and a 22mm I.D., and press fit them into a pair of axle blocks to be used with the undersized axle. Use of a good grade of steel is critical, since the walls of the sleeve will only be 1.5mm (.059").
