It was a larger engine than I ordered. The engine was thicker. I was unhappy but my client needed air conditioning. I finally got it working, but it's also heavier than it should have been on the device. Even after trimming the shaft (which is normal) it still hangs lower than the right one, had to adjust the blades to avoid hitting the roller tubes, which I don't recommend. The one in the picture is what the eldest looked like, not what appeared. I didn't have time to take care of the return.
