Luckily it didn't take out anything else. It was the lower smooth roller pulley that disintegrated, and it happened on the trail! I noticed the trans wasn't shifting per usual and just a general loss of power BUT i was on the trail ALL day that day so it wasn't noticeable until we started climbing out of the valley we were in. We had pulled in to our last camp spot for the weekend and I decided to pop the hood and saw that the belt was loose! Cut the belt out and was able to gingerly drive it home, even on the highway over a mountain pass.
Was able to source the pulleys locally at Napa and another parts store, each had one in stock so ordered the other two and extras which should be here tomorrow morning. Up and running again soon.
I've had my SC in for just under 60k miles
Smooth pulleys (2) Napa 38006
Ribbed pulleys (2) Dayco 89009
Will find tensioner later and carry as an extra. Also ordered another extra belt.
