The squirrel cage is about 3/8" shorter, not 3/4", but still allows recycling of incoming air.
I believe you are correct there Fred. Thank you for correcting me on that, I just remembered the 3 I guess when I measured the difference between the ACDelco and the original, it was about a year ago that I measured it.
Point remains. The replacement motors out there do not perform anywhere near what the originals do.
It’s not about a bigger cage, it’s about the way the ducting around the fan is configured.
That 3/8” (Thank You) occurs at the top where the original fan almost touches the duct (1/4”gap), the aftermarket replacement ones that are usually white in color, leave about 3/4” gap right where the air is leaving the duct into the fan creating turbulence and the recycling of air, that decreases the fan output almost to half that of the original blower motors.
But if you want to imply to other people who are considering replacing these motors with aftermarket ones is a good idea, or that it’s ok is something I can’t support...
It’s a big difference from personal experience.
Do you still have just the motor component for sale ? I’ll buy that from you as a backup.
I live in the Palm Springs area of SoCal and when your A/C stops working, it is almost life and death situation LOL 😝
