Knocked out the rear ones today as on the MOT for the past two years they state some play in them..(front too) I've been keeping an eye out to make sure they are ok and all has been good but they are all getting done now for peace of mind...
Now I've come to order up some more and had a little extra time as work was snowed off today so was looking on Simply bearings web site, I was going to order from Sprint manufacturing as previosly as I need a few bits but saw something that may have explained the Loose/play feeling at the wheels, the bearings that are were fitted have C3 marked on the inner or outer race, now according to Simply Bearings C3 is a rating for high speed applications where heat or a build up of heat may happen and the clearances in the bearing are loose from the factory to allow for expansion in these conditions.....they also state C3 is not for Motorbike wheels, all the rest of the spec and quality is the same apart from this http://simplybearings.co.uk/shop/p6...ove+Ball+Bearing+20x47x14mm/product_info.html if you follow the link and click on the C3 explained icon.
The play in the wheels was minor and didn't get any worse so I'm thinking this C3 spec is the cause, I have ordered standard clearance bearings to replace these and will see how I go.
None of this may be an issue ? and I'm not sure what the factory spec is but should your MOT man keep on mentioning your loose wheels bear this in mind when eliminating possible causes.
Cheers
