Hey can anyone tell me which way the waterpump drive comes out of the case? The repair manual does not show how, and I don't want to hammer it out. I removed the c clip at the intake side. Does it just press out from the water pump side? Thanks

No clue...! Ha! Sorry, not much help, but I read your thread at least.

The bearing holds it in, press fit. It should push out toward the black gear.

Thanks SEG. Hey, what would usually cause a crank bearing to spin? The exterior one on the PTO side fell apart when I pulled the crank out of the case, but the other shows normal (2 on each end). Going to service it properly, but wondering what causes it. Any ideas?

A failing seal will cause the bearing to fail.Ski-Doo has corrected this on the newer sleds by sealing the bearings and adding grease to lubricate the bearings instead of the fuel/oil mix lubricating the bearings.
Good thing you caught it before it caused major damage.

Thanks for the info.
