OK, so I removed the fan mounting assembly for another look. There are two bars that I figured are for reinforcement on the front of the hub mounting bracket. The hub bracket has ‘6’ holes, two on top and four on the bottom. To get the bar to line up with four holes on the hub bracket, that puts the bracket in the ‘high’ position – aha! To put the bracket in the low position, requires the two top bolts to go through the bar, but +NOT+ into the top holes of the hub mounting bracket. Seems like a goofy arrangement.
Now that I have this in the lower mounting position, perhaps I can get a couple of belts of the correct size?
