I have a feeling that the hub is cast round the liner so swoppingone to another won't work, but on here somewhere is the address and number for a man in huddersfield who will machine out the old liner and shrink in a new liner then machine to size---he did several 500/550 rear for me quite cheap as i was in no rush.I would not do this for a "Racer" as its possible for the liner to move if got very hot but i doubt very much you will do that to yours AshFound itPaul Jackson Huddersfield near Junction 23 M6201422 378100
