Re: Rear chain touching on the inner primary case

Thanks Ian for your reply. I use Regina chain, I use two cork washers for the inside tube spacer (one at each side) between the inner primary case the outside cover. Behind the inner primary case I use only a tube spacer and not any cork washers

Re: Rear chain touching on the inner primary case

I usually fit the inner cork washer behind the inner cover at the outer end of the first tube..That seals the cover from behind. I fit the other washer at the outer end of the tube that is inside the cases to seal that side.

To test the set up you have, slacken the footrest bolt completely so the cases don't have any pressure exerted on them. Remove the footrest as well if necessary to achieve this...Then reach behind the cover and test to see whether the inner spacer tube has any free movement axially, it shouldn't...You can just get to it by hand from underneath but you may perhaps need to use a long screwdriver or similar...

I believe the assembly drawing found in some BSA manuals is incorrect....Ian

Would it help to put the fish on the inside?

Could also be a twisted rear sprocket or a defect bearing.
