  • o-ring type chain too fat, wasent out in the 80,s.

  • I'm thinking wrong sprocket. Is there an offset? Is the o-ring behind that metal sleeve?

  • BTW, I have an o-ring 520 on mine, no rubbing.

  • i'm using a very narrow 520, DID and I have a spacer behind it, i've tried several sprockets, the 14t rubs but not very bad, a 12 is awful for rubbing, so i'm uncertain as of what to do

  • + large o-ring behind that sleeve (oil seal)?

  • I have a new o ring and seal, i haven't taken the old seal out to see what the o ring looks like

  • It's not behind the seal. Mine slides on before the sleeve goes on. That could be the 1/8" you're missing.

  • pull the collar out, make sure there's an o-ring behind it.
