My crankseals on my 76 moto ski nuvik 340 (same as ski doo olympique) are leaking. I have everything off to change them but i cant get my clutch off. I got the outside half of the clutch off but there is still one half of the clutch stuck on the engine. I need a clutch puller to get this half off, but i don't know what kind or size puller i need. THere are pullers here http://www.mfgsupply.com/SnowClutchP...on_id=hrohfFyb
But i cant figure out which one i need.
