I still am not sure why they used the seperate dog clutch piece, which I assume has a keyway of some sort, at least a pin it rides on, and did not just put a key for the upper end to slide on.

Maybe the answer is simply that they didn't have a collar in the size required by the shaft but they already HAD a dog clutch in the proper size so they used it? You know how the Parts Department loves it when one spare part can be used in a multitude of places.I think you're right about the keyway, I'd think that this whole assembly would have to be keyed to the shaft. You'd want as much surface area driving this beast as possible. Wouldn't a single pin hitting in the same spot all the time cause un-due stress and wear at that point? It would after all have to take the stresses of moving the whole machine.Don
Chris,Beyond words. I will have to get a length of cloth to wrap around my head so my jaw won't drop.John
I think I will make the small clutch end with a keyway, the large part with a recess to let it slide down.
Looking great Chris. You'll have the shovel moving under power in no time. I wonder if the original designer of the end bell at the right of the last photo had cleared a drain or toilet recently - it looks like an Oscar-ready version of a plumber's force cup..... (now taking cover)
