Rated 5 out of 5 by 2reviewers.
Rated 5 out of 5 by Nice motor. Purchased to Replace failing Carrier OEM. Simple install. Beefier than original (larger motor casing, longer shaft, etc.), no problem; trim-to-fit. Stingy, Draws ~ 4.0 amps on medium. Have to watch directionality, can change the rotation by polarity index built-into harness. February 13, 2013
Rated 5 out of 5 I used this motor to replace an A.O. Smith motor (Item # 4MA66) that was noisy beyond compare, and many times failed to start on the lowest speed. It's so quiet my wife can't tell when it's running! October 28, 2012

Answer: 
The rings shown in the picture are included if you need to shim up to a larger size or rubber bushings which are on each end of the motor. The motor then can be mounted in all of the standard size mount variations. You may not need to use them. They are included only in the event that they are needed.

one of the questions on the page for this item is:
What is the wiring for a 3 wire furnace. Do you need to connect a capacitor?
Grainger's answer was:
Grainger Employee

I will email you a copy of the wiring diagram and that has information on 3 wire wiring.

I, too, would like a copy of the wiring diagram for this product (can't understand why neither the OEM specification sheet and the OEM Wiring diagram are not posted on the site.

All of our new motors have the wiring diagram on the motor tag. If for some reason an older motor that has been in service for some time does not have a tag on it, give us a call at 1-800-Grainger so we can get the information to you now.
