I have a 2012 T750 (200 hrs.). The air conditioner pulley that is attached to the crankcase pulley broke off. Three bolt heads sheared off and the pulley flew off, luckily there was no damage other than the ac and alternator belts being shredded. The belts are the stretch fit style and do not have a tensioner. I am told that the new belts are undersized but these really seem too small to fit. Anyone have any tips or tricks for getting these installed? The manual says to use the breaker bar for the ac belt and a pry bar for the alternator but there is just no stretch in the belt. It seems that these belts are so tight that it caused the pulley to break free in the first place. These are the right belts from the parts manual and the numbers matched the old ones. Anyone else had this problem?
