having struggled over a period of time ( on and off 3 weeks to actually fit it into the bracket, As I was looking at the machines finish I noticed it wasn't abit should be looked like the tool that cuts the sizes on the rubber seal end had broken . I checked the diameter sizes to the old one and they were 3 mm bigger, I got round this by actually grinding the outer dia down . I am still in the process of bleeding the clutch to see if it is actually any good.
