This happened to some of us last year, too. We tried trimming the circlip down so that it didn't rub, but ended up just taking it off. We went through the season without a problem. In fact, we just stripped the transmissions for the first time since we assembled them last January, and they were perfect inside -- no visible wear. These are nice transmissions (although our left-hand transmission still growls just like it did a year ago).
