OK well depending on what we find I will need the HIN # at some point, this unit had many issues and there was many changes mid year,
So belts get hot for a couple of different reasons, first off you need to insure that you have GOOD air flow into and out of the CVT area, first easiest thing to do is remove the snorkel on the top of the CVT cover and start the engine, in neutral rev it up with your hand over the opening, it should basically blow off your hand, if that seems to be an issue then check the inlet snorkel and make sure that its free flowing and no obstructions or the snorkel is not collapsed.
Next you need to check the belt deflection with a good belt, I suggest that you use an OE belt on this model, aftermarket belts seem to have tolerances that are all over the place, if you don't have a manual I can help you with that procedure.
Next either get all wheels off the ground, (or you can ride the unit, be careful as my next suggestion is to run the unit with the belt cover off)
Remove the belt cover, (DO NOT TURN THE KEY ON WITH THE ENGINE BRAKE PLUGGED IN) then make a bridge wire for the "Belt Detection Switch" (2 wire plug) this will by pass the swtich and allow the unit not to go into belt failure mode.
Next what the clutches, see if they are moving freely through the range from basically idle to wide open throttle, again if you are going to ride the unit and check this, just be careful as the clutches will be exposed to your leg.
I have to step out tonight, so I will likely get back to you tomorrow.
Let me know what you find
