brettypeeps:
I agree with Brunmie you will normally need a top hat washer. Gets the spacing correct and keeps the power disk central. Axle is 19mm and power disk 22mm. I might have a spare you can have foc

See if the disk rattles about on the axle and let me know if you need it and I will have a look for it :daumenhoch:

oldskooldayz:
right silly me yep defo needed that washer that slips in the disc to stop it moving all over the place  :-[

ive got it down now to a 3-4 mm wobble so i will play about with the shims till i get it spot on or really close

Big thanks for the offer on the top hat washer foc mate  :daumenhoch:

thanks for the advice guys and next time i will check the full contents of the box before installation  ::)  ;)  :daumenhoch:
