Try it with the shim you have, the inner race normaly comes back off easy if you need to add more.If the shim is too small the lower yoke binds on the frame.For shims i just put 1mm shim 30mm id into ebay
Hopefully you can understand now why Graham never fits these type of bearing, they are an absolute pain and just stick up too high. He did try on his 550 Mongrel he's recently built but gave up and went back to original type. It would have worked if he had milled down the internal lip by about 5mm but he would have had to strip the bike down completely to do it and you can't get a whole frame in the milling machine anyway.
