...now I just have to fix that pesky leak around the front sprocket
I got the fix for that one
Once the seal and collar are out you'll find an o-ring on the shaft. Change that o-ring with one that is 1-1/16 X 7/8 X 3/32. I bought a bag of them at Home Depot and they were $.25 each. The Home Depot stock number is 35734B. I posted the sizes for non-us members, I don't think Home Depot is international.
Anyways... once that oring is changed out with the new one you will need to take the collar and grind a little bit at a time off one end of the collar - do this slowly, once the metal is gone you can't put it back
.
I ground and test fit a few times before I could fit the retainer clip back on. This is going to be a tight fit and that is what stops the leakage. I also put the non-ground on end against the oring when I slid the collar back in, just to be sure there weren't any burrs that would damage my new oring.
I did this about a year ago and have had not one dribble, the sprocket has stayed dry as a bone. Before I did this i was changing that little seal and oring every month.
