Watch the motor current draw!
As Soren suggests; If the belt is wrong (too tight), the motor will see a too heavy sideways load, and its bearings will go bad in no time = goodbye motor. I’ve seen it so many times with cheap junk belts from Portugal and Germany sold in large numbers on Ebay etc.
Speeds being low after replacing the belt could suggest this kind of situation.
