I recently bought a used 2000 Polaris sportsman 500 4x4. The CVT belt started to shred and CVT was making a high pitch whirling noise, so I decided this was a good time to do maintenance on the clutches. I bought an EPI clutch kit and an EPI severe duty belt because I drive through a lot of mud trails. The kit comes with a new (red or orange) spring for the primary clutch to replace the stock (blue) and new CVT weights. It also contains a new (black) spring for the secondary clutch to replace the stock (white) one along with new helix. I noticed the primary clutch buttons were worn to Hell, so I'm ordering new ones and will replace asap. I had to order the spider removal tool, so I could remove the spider to access the clutch buttons. There are a total of 6. I noticed the bearing inside the secondary clutch looked like it barely had any grease inside it. I was considering replacing the bearing or just cleaning it really well and repacking it with grease. Before I re-assemble the CVT, does any one have any advice on servicing this bearing inside the secondary clutch. I can't find this bearing on my Polaris parts layout diagram and I wonder if it's only sold with a new clutch? Being the bike is 13 yrs old, I am pondering replacing the bearing. The bearing doesn't look too worn but the grease inside it looks like crud. Maybe the previous owner got water inside the cvt case or something? Any suggestions how to proceed? I'm new to Polaris, but I am experienced doing ATV repair on my Yamaha. CVT is a new animal for me.
