Hi all
Among other problems, I have discovered that my newly acquired MC21 is leaking copius amounts of oil from the gearbox output (sprocket) shaft seal. I'm hoping that it's simply worn and an easy replacement but being an NSR newbie I have a couple of questions:
I'm assuming the seal can simply be replaced (ie: the old one pulled out and the new one slipped over the output shaft) without removing the gearbox? Am I right?
Is a leaking seal generally indicative of other gearbox probs - worn bearings etc?
Any pointers very welcome
Cheers
