I also believe you got the idler shaft key.

The motor shaft key is standard key stock and is straight. I am not sure of the size(3/16"? 1/8"? 5/32?) since I be 'out of town'. The end does not need to enter the fan sheave spacer. The key must be inserted fully into the keyway in the fan sheave. The fan sheave set screw holds the key in place. It should not be long enough to reach the sloping end of the milled keyway slot, but stop just short of there.

When tightening the fan sheave set screw, do not be bashful. Blue loctite is my preferred 'insurance' against loosening.
