If the chain snagged something on the underside of the box that could stress the tensioner enough to fail it before the chain jumped. I'd look carefully underneath.
+1 also check the chain slides under the box and see if they are worn thru, usually when they catch the apron something breaks. also check to make sure someone hasn't messed up and has a different number of links between slats. |
