Thanks Stephen. I called IR to ask about the NEMA frame size of the motor for this compressor and the rep told me that he wasn't sure, but he thinks it's a 182. Looking at the dimension of attached picture, 2F and 2E motor dimensions certainly fits the mounting holes.

However, there is a 2340IR compressor on Ebay and the seller told me that the motor has the following specs: HP 5, RPM 3450, V 230, FLA 22.5, FR 56, HZ 60, PH 1, CODE H,INS B, MAX AMB 40 C,DUTY CONT, SF 1.15 SFA BRG BALL. This suggests that the motor is a 56 frame. I don't know how that could be. A 56 frame has a 2F dimension of 3", which is too small for any mounting holes in the picture.

Am I reading the motor specs right? Could the 56 frame motor mounts on the 2340 compressor via an adapter?
