1991 Xp Crankshaft question
Hey guys, quick question for you all. I am trying to find a 580 crankshaft for a friend who is trying to get back on the water for cheap. I was wondering if the following pic would fit a 1991 580 dual carb. The guy says it is from a 1995, but I thought the bearings don't have o-rings in 1995. Sorry for the ignorance, but I have only worked on Polaris so far.

That is a '95 crankshaft. There are 3 o-rings on it actually. 2 on each bearing as yours is showing, and one for the labyrinth sleeve in between the two bearings. If they are interchangeable I wouldn't know. The fiche doesn't offer part numbers for the crankshaft assemblies. They sell them with the crankcase as a complete unit. I would suggest talking to a local shop and ask them about where they send their cranks out to get rebuilt. The rebuild shops should know I would think.

Anyone else know if this will fit in 1991 cases? Is the only difference the two MAG bearings and the labyrinth seal? I would need to change them to 6206 NR instead of 6206 and add the seal between the pto bearings?
