The Rhino 660 is a popular off-road vehicle because of its side-by-side seating configuration and room for multiple people. These UTVs use a belt to connect the motor to the transmission. This belt can break, and if it does, you won’t be able to drive the vehicle at all. To fix the issue, the UTV has to be disassembled and a new belt installed. This process should take about an hour.
1) Remove the trim panel around the base of the seat by pulling it off of the trim panel, using your hands to release the clips holding it in place. Unbolt the front seat from the Rhino with the 3/8-inch ratchet and sockets. Pull the seat out of the UTV.
2) Unbolt the coolant line hose clamp with the 3/8-inch ratchet, extension and sockets. Unbolt the cover from around the belt using the 3/8-inch ratchet, extension and sockets. Unbolt the x-shaped cover on the rearmost sheave of the assembly using the 3/8-inch ratchet, extension and sockets, then turn the sheave 90 degrees to the left and pull the sheave out.
3) Thread the bolt included with the replacement belt kit into the foremost sheave by hand. Tighten down the bolt using the 3/8-inch ratchet, extension and sockets until the sheave and the belt loosen. Unbolt the rearmost sheave with the impact wrench and sockets and then pull the sheave and the belt off as an assembly.
4) Install the belt onto the remaining sheave, then reinstall the factory sheave and the belt onto the factory location with the impact wrench and sockets. Remove the bolt on the foremost sheave with the 3/8-inch ratchet, extension and sockets. Reinstall the x-shaped cover on the sheave in its original position.
5) Reinstall the cover and coolant lines using the 3/8-inch ratchet, extension and sockets. Reinstall the seat with the 3/8-inch ratchet and socket.
