Even in generators. What a buzzkill to put in the work of breaking the motor down just to find an ali winding.
Every Condenser unit i get from the hvac shop, my tech buddy or a random find that have the freon removed always still have the oil. i wonder if removing the oil is an extra part of recovery that they leave the oil in to do the job faster.

I hear ya on the Alum units and motors. I had one of those 200lb S units i wanted to breakdown. i did 4 others in the past and when i did the last one it was alum windings. that was when i retired from opening sealed units. I also have found alum motors from generators. Its like i got 12lbs of copper coming to go to nothing but shred.
