:crazy: Hey y'all I need some help on how to change the crank shaft seals on my 1978 Skidoo Everest 440. I can't seam to figure out how to get the clutch off the shaft. I have removed the lock tab and bolt from the end, but now I don't know if the clutch is pressed onto the end or screwed on. I have tried to feed string down a cylinder and then torque the clutch but it does not seam to loosen up (turning counterclockwise). Next I tried a crowbar against the ring gear and block but it wouldn't budge either. Does anyone have advise on how to get this thing off? Surely, I don't have to split the block appart, do I????
