Help please. Having the wheels powder coated so talking to my car mechanic who said he would remove the bearings for me and save the money that Moto Rapido charge. He brought the wheels back and asked how do the cush drive rubbers come out? I have the workshop manual but unable to find any reference at all to the cush drive. can some learned person explain how to get them out and will this damage them and so need to replace them? Regards Steve
