Just changed rear hub and it rocks on layshaft when torqued,took hub off tried old cone,same, put new cone on with extra washer behind cone and it torques up,this is a new SIL hub and cone,any one got any ideas why the old one was ok and the new one rocks or has any one had this happen or do i leave the extra washer on.

Are you sure that the endplate is not working loose? This is the typical cause of hub rock and is one of the things that can really put a casing at risk (works loose and damages endplate stud threads).

Good luck getting it sorted.

Thought that at first but put old hub back on and all ok + as said extra washer stops rock on new hub and cone.

there just not made the same and also the further you push the hub out with extra washers the less for the brakeshoe to work on

Extra washer is only about 1mm at most,think you could be wright tho after all SIl stopped making scoots in the 90s, you have to wonder where the parts really come from.

It sounds like the hub domed nut is bottoming out on the layshaft before it has chance to tighten the hub onto the cone.To test this,try another washer behind the domed nut instead of behind the cone,or instead of a domed nut try an ordinary nut(without the dome)on the end of the layshaft.

yep tried that straight away,had the bottom out problem with mate couple years ago.

no rude comments please.
