I have a 660 rhino and yesterday got it in to deep mud. This is the first atv/utv I have had that is belt driven. After getting it out of the mud by winch, the rhino wouldnt go foward or backwards. It finnally started to catch and I drove it around for a few min on flat ground but it still would only go about 10mph. I pulled the plug and drained the water out of the belt area. It is completely dry now but still will only run about 10mph, when you give it gas it just revs up. I may have burned the belt up trying to dry it out. Does anyone know if this is just a slipping or worn out belt or other problems.

 

I've got the same problem. I do alot of deep mud/water, and has been getting worse. Thinking it is dirt in sheaves somewhere? Burnt clutch? Lets hope for an answer.

 

I would say belt is stretched too much.if no water is present belt should grab and go. I scuff the area where the belt rides to give it more grip on belt if u can find out dimensions of belt new and compare to now too much belt will not grab at all

 

Disassembled my primary sheave, it was packed with mud! No chance for the weights to move. Will reassemble tomorrow and let you know if that was it.

 

dont forget to repack the primary where the rollers are at with new grease.

 

Cleaned it (2 Hrs) greasedit with Lucas x-tra heavy duty wheel bearing grease (marine grade), and it works like new.

 

Glad you got it going, can someone help me out.; whats the center to center on these rhinos.

thanks
