Sportsman 500 HO clutch problems

I own a 2002 sportsman 500 HO. In the drive clutch is a brass washer that keeps wearing out. When it does the clutch will not disingage totally making it hard to shift. I have repaced this at least once per year since i have owned it. Is there any thing else i can do to?

I am not sure but bought the machine new in 02 and have never changed the weights. I live at 13000 feet above sea level.

weights might be worn out, it is one of the wear items the primary has, and it might be causing weird engagment of the clutch

Quote:
Check the weights for side play since they will eventually wear a “V” at the base of the clutch tower over time. This “V” will eventually result in the tip of the weight swinging off the roller and contacting the spider. When this happens the clutch hangs and the clutch shifts erratically. Flat rollers or flat spots in weights can occur. This condition also creates more wear on the sides of the weight bushing. If your weights run true you will wear the clutch bolt before wearing out the weight bushing.
this above quote was part of a maintence tip from the magizine snowest. there is almost no difference in the way a snowmoible clutch works and a atv clutch works as far as polaris goes, and this article is directly referring to polaris clutches....

typically at the shop often times when washer and bushings were being worn out one possible issue was worn out weights.

what part exactly is wearing out?

I just installed a new washer in it last weekend and I could not find anything worn in the weights or elsewhere. I have also checked clutch alignment but it also seems fine. I was hoping this was a common problem with the HO model.
