Q1. If it's not wired, how do you know the motor is good?
Assuming this is a [serviceable] fractional [1/6HP] psc. [?] :-
850prm on the plate means it has 8 poles, an expensive to replace item [Baldor $600+]. And explains why the replacement ran too fast.
[Motor rpm = 120 x hz / no of poles.]
Winding A-B is the run winding.
Winding C-D is a start winding, [you can see the capacitor between slots 16 and 34 in your drawing].
The wiring is simple. Take 120v 60hz to a link fitted between C and A.
Fit a link between D and B and connect to the other side of 120V 60hz. Fit a switch connection and try a quick blip to see if it starts. Take care not to prolong the current if all you get is a buzzz!! No start? The capacitor may be duff.
About 5uf would be the approx cap size for this size motor, if the markings on the original are unclear.
Now all you need to see is if it spins CW or CCW for your application. Some pscs can be reversed.
Good luck. Let us know if and when you've let the smoke out!!
