The pulleys arrived tonight, so I grabbed the motor to see how they fit. I'm actually very happy with how they fit. I will be modifying them a little, but not much which is great news.
The top pulley here doesn't fully go on, its only about halfway on the shaft. I'll have to modify them to get it to slide on farther. The general rule we use in the industry I work in (industrial conveying equipment) is you need 1X diameter engagement on couplings and pulleys. So, that is what I will be aiming for.
