Was out riding all weekend on my stock 07 660 se. At the end of the day i started hearing a grinding noise when rolling up to a stop. It dosent seem to do it at all on acceleration. When i got home i put the rhino up on jackstands so i could run it in 4x4 and listen. Didnt hear the noise, every thing seemed to spin freely. Did a search on the forums here and lots of people seemed to have similar problems when they had a bad one way bearing. Took the cover off the clutches and removed sliding primary sheve and belt. Primary shaft seemed to spin smoothly one way and engine turned over when i tried to spin it the other way. When i was riding the machine it was hard to pinpoint where the sound was comming from. If theres something different i should be doing to check the one way bearing or if anyone has any ideas please help. Thanks in advance. Rob.

I also have the same issue, it for me is around 10-15 mph while slowing down. Sounds like a binding type noise.

sounds like a one-way bearing going bad... does it engine brake down hills or free roll?

If the machine free rolls down hill with no engine braking while you hear the noise, it is the one-way bearing.

If it's making noise on deceleration, it's time to change the one way. If you give it a bit of gas, the noise will go away but as soon as you let off the noise comes back.

That sounds like it. I'll order a new one today and the gasket. Anything else I should look at while I'm in there?

Check your clutch shoes for wear and drum for grooves. You can get clutch shoes on ebay for about $100 if yours look worn. Mine were close when I changed the one-way... it feels like it did when it was brand new.
