You got me thinking cuz it had been about thirty years since l had done one so l flipped over a 904 l had laying out in the yard and checked it. The pan was already off so all l had to do was back off the 9/16" nut and unscrew the adjuster, pushed up the band lug and popped out the strut, and the arm swung out of the way with room to spare. Maybe you're thinking of the double wrap band. I don't have one handy to check.
