I did check that and what I found was, the belt got tighter for sure, but I still had lots of play in the belt. Maybe a 1/2 inch from side to side. It starts out cold at about 3/4 to an inch of play. When I looked closely at the broken shaft I noticed what looked like air bubbles in the shaft where it broke. I figure it was either a bad piece of metal or metal fatigue that caused the problem. I wish I still had the old shaft, I would post a close up photo of the break.
