Hi mate
The answers to all your questions are in faq's, but yes, what you have found on ebay should fit, as long as they are standard CRM wheels.

realise now all the details are in the FAQ's - i did search the forum but only found a thread on the seals...
I have a problem with my back wheel - the seal / bearings on the sprocket side look like they have been pushed in slightly
when i put the back wheel on - the sprocket bolts almost touch the swingarm - to stop it rubbing i have to adjust the back wheel so one side is further back than the other -
I will post a picture soon - if anyone has a picture of a back wheel could they post it please

How much thread of the sprocket bolt is sticking through the end of the retaining nut?

This is what it should look like from the rear, sounds like yours is assembled wrong as their should be loads of clearance if you have the correct spacer fitted (look at this spacer for shape).
The bearing kit will fit, but do not push the seal on the sprocket side in too far, just make it sit just below flush with the hub.

does this look like the bearing has slid in somehow?
when i put the spacer in the hub - the spacer is almost inline with the sprocket bolts - like a 2mm clearance

Have you put the spacers on the right sides?

Bearing is fine, the seal has been pushed in a little too far that's all.
Your sprocket bolts are wrong, looks like you have washers underneath them, should fit like my photo.

so if i change the seals and remove the washers you think that will be fine ?
there is no play in the bearings

Maybe a silly question, bit did you compare the new bearings to the old ones, in size like?

How big a gap is there between the bushes and the swinging arm, before you tighten down the axle bolt? It should be just a sliding fit
