Primary Sprocket Seal Change

Recommended Posts

Hey everyone,

I've got an '08 450F that I got about 3 months ago. Haven't ridden it much this summer (6 hours maybe) and I took it out for a little spin this evening. When I got back it was leaking oil out of the primary sprocket seal pretty bad. Is it possible to change that seal without splitting the case? If so, how would I do it?

Thanks in advance for all your help!

Just basic hand tools. Remove the front sprocket and gently pry the seal out after removing the collar. You will probably have to remove the rear wheel to get the chain loose enough but before you do that crack loose the sprocket nut first.
