Here is a pic of the motor as it weighs whole 27.8 lbs
First as you can see there are 4 screw/bolts that you need to remove and then both ends of the motor will pop off. Center shaft can then be pulled out .

Here you can see the center shaft out and the outer casing with all the copper in it.

Here is the center shaft. On the end is a cast aluminum fan. Just wack it with a hammer and it breaks right off. Ended up weighing about .25 pounds.

Here you must cut this weld or grind it off like I do and remove the outer metal case.
