Glad to hear things went easier, sorry to hear the bearings went bad so fast.
Like I said earlier, I bought an entire fan assembly to be able to swap out the original one and then at my leisure try to get the fan off.
WELL, a couple weeks ago I finally got around to making the swap, and immediately the new motor had a really loud harmonic whining sound, like, wa, wa, wa, wa. I shot a video if you care to see it
But I still couldn't get the fan off the original one UNTIL I made this set up. Its a 1" fine thread nut with a 3/4" nut welded to it and a 5/8" hardened bolt that just fits in fan hole. A couple big wrenches and some elbow grease an it popped off.

I called AHS about the whining sound in the new motor and they said it could be the bearings or the fan is out of balance, so the sent me out 2 bearings and a fan blade. Installed them and it was the same.
Meanwhile the original unit with the new bearings is purring like a quiet kitten.
I have to send the motor back and with get a new one or a refund.
I also loaded up the shaft, both set screws and the bolts that hold the motor to the plate with high heat antiseize.
