Hey Paul
Sorry for the delay, we had a wind storm here last weekend and I had a bit of roof damage that I have finally finished fixing. I got the pulley in to UPS last night.
The tracking number is 1ZA1129E0329359226
In the box you will find a large pulley, split taper bushing, a key and some bolts. Two of the bolts and the lock washers are used to tighten the bushing, the other two are extra just in case.
The key is a standard size key for that application. I know you had a machine shop turn down that shaft so if they did it correctly they also re-cut the key slot. If the key is too thick just use s bench grinder to remove a bit from one side. Since you are not using this motor for continuous service the key may not be needed but ya have it just in case.
Here is a link with installation instructions if ya need it.
