I had not considered and that was that if the wings were bent out, I might have to bend them back before anything else. It should have been obvious to me that this is exactly what had happened, because when the unit was new there was no gap between the auger shaft and collar bearing. I was pretty sure that the auger shafts hadn't shrunken in the cold air, ha! I measured everything and found a difference of an inch between the front of the wings and the back of the unit. It was now apparent to me that the wings on the 2750 are susceptible to bending outward, which surprised me somewhat because, although they are stamped sheet metal, they seemed fairly rugged. The wings bent slightly outward and the flange bearing cover on the inside of the wing pulled against the shaft bearing. The set screws on the collar shaft bearings weren't really meant to withstand (and obviously didn't) a lot of sideways force and would slip on the drive shaft a limited amount. That meant that as long as those wings could be bent by hitting the ice hardened snow banks, I would be right back in the same predicament as before with the pins.
I came up with what I like to call: "A $65.00 solution to a $1.58 problem." The wings won't bend out anymore and the shafts maintain precise positioning now, so when I shear a pin, it's a 5 minute job. Most of that 5 minutes is walking to the basement to get a new shear pin and wrenching the thing on, but those holes line up every time now. I had more time on my hands, so I added another support up higher on the wings using wire cable as an alternative....just for the fun of it. I have no intention of ever getting rid of the 2750, so I didn't care if it came out looking bad...as long as it worked...and it does (work that is!) As I said, although it was a $65.00 solution, I got about $1000.00 worth of fun working on it and just playing around with it, which sure beat sitting in front of the television waiting for summer.
My next project is putting a hydraulic chute rotation system on and I've posted some questions regarding that on TBN already.
O.K., go ahead and make fun! Dyer, retired
Nice fix John! Have you used it yet? Hope you're getting better day by day.
