Rated 5 out of 5 by from Good availability We bought this a couple weeks ago. We had a compressor motor go bad and bought this as a replacement for an Ingersoll Rand motor that burned out. So far so good. It fits perfectly and has been running our compressor for 4-5 hours a day now. Motor was in stock and available right away which made it perfect to eliminate down time.

what kind of oil we can add if needed and where is the location of oil plug?

The motor is electric and needs no oil. Also, the bearings are sealed so no lube is needed.

The website says that the list motor is CW rotation only. The nameplate on the motor in the pic shows this motor to be reversable. Which is correct?

Asked by: Kevin1807
We spoke with the manufacturer. The motor rotates both directions. We will correct the error on our website.

The specs indicate clockwise rotation; from which end? Shaft end or other end? How do I change direction if necessary?

Asked by: Sabine
The rotation of the motor is clock wise. The rotation is determined by looking down the motor opposite drive end. IE standing behind motor looking across to shaft end. That would be clock wise. Unfortunately, this motor can not be reversed.
