question about a 2005 sportsman 90


Recommended Posts

I have a sportsman 90 for my kids. There was a slight slip in the gear when i purchased it(when they ride together or there is more tension on it). I'm assuming this is the drive shaft and I've been debating on trying to fix this myself. Just curious if anyone has had this problem and how complicated it is to fix?

hello dirt demon.

The problem i'm having with the polaris 90 sportsman is that when starting from a stop or climbing a hill the chain sproket from the engine doesn't turn and there is a loud clank. I'm thinking that this would be a drive shaft issue. I've never had one torn apart before and don't think there are any belts? I could be wrong. I'm thinking that the drive shaft has been worn to cause the slipping?

There are belts and clutches, either one could likely be the culprit. There is a cover in the side of the motor with a guard on it, the guard is held on by two bolts. You should be able to see the bottom portion of the belt after you take off the guard. After take off the guard, then the cover behind it, you will see the drive belt assembly and the clutch assembly. I would check there first before looking into the drive box. I would highly recommend buying a repair manual, it will probably have all the info you need to figure out your problem, and it will definately have info needed to properly disassemble and reassemble the machine.
