Another belt replacement tip/trick to share...
When possible, replace worn out belt when its warm/hot. A warm belt tends to be much more flexible to work with. And, keeps the bare hands warmer during deep cold time. For new belt, pre-store in the warm temp house (not in freezing cold garage - ouch!) before installing as well. Thus, ensuring its warm / flexible as well.
And when doing rides away from shop tools, always remember to bring a sharp utility knife in sled's tool box as well. A few times, I seen a belt blow and wrap itself around the clutches. Their strings (ouch!) needed to be cut out with a sharp / strong knife - before above video trick can be used to install the new belt.
Hope this helps as well....
