My 07 Rhino 660 has suddenly stopped holding on a downhill. Reading various threads I think I will need to replace the one way bearing in the clutch. I have a service manual for the Rhino. The manual shows 5 different special tools. 1 - Sheave Fixed Block. 2 - Sheave Spring Compressor. 3 - Primary Sheave Holder. 4 - Sheave Holder. 5 - Universal Clutch Holder. I am wondering if they are really necessary. For parts, I believe I will need a new one way bearing and a housing gasket. Anything else? What should I look around for while I am in there?
