I knew something was wrong Wednesday on my ride to Booker Hot Springs. My belt was slipping & not allowing me to go any faster than 40 mph in high or 20 mph in low. Normally I can go 84 mph in high & 42 mph in low. When I got home I pulled the clutch cover off & blew the dust out with compressed air. The engine seal behind the primary clutch was leaking oil onto the floor on the clutch housing & out onto the skid plate below. I pulled the belt off (part# 3211202) & washed it in soapy water to get the oil off it. My friends who had to wait for me on the ride looked at the belt & said there was no damage to it. I cleaned the primary & secondary sheaves with brake cleaner to get the oil off them & took the Pro XP for a test ride. The clutch was making a horrible knocking sound so I made an appointment to see the dealer (3 weeks was the soonest). I used my YXZ for the rides on Thursday & Friday. On Sunday I was getting curious as to what was wrong with the Pro XP. What would the dealer say if they saw the clutch & belt looked good? Would they say, “Keep riding it & come back when you can show us something wrong.” ? I decided to take it for another test ride. I got half a mile from my house running at 60 mph when there was a very loud explosion & what looked like yellow cotton & black dust was floating in the air. I popped the clutch cover off & the belt (part# 3211202) had disappeared. The black plastic behind the primary was broken & the inner sheave on the secondary had a one inch warp to it. The spare belt got me back home. Now I have a lot of questions. Is this under warrantee? Am I driving a time bomb? How can a belt & clutch look perfectly good & then explode seconds latter? Will it take 5 or 10 belts to go 10,000 miles? Most cars & trucks go 100,000 miles without needing a belt!
