I've noticed on the mid to late 1980's Maytag washers (with orbital-drive transmissions) when you tip the tub far enough at an angle-the metal tub ring rail guard will strike the washer top metal flange-metal-to-metal! Now I've seen many other washers do this, plastic-to-metal, but metal-to-metal you would think during a very unbalanced load, the washer part(s) would get bent. The older helical drive Maytags didn't have this issue, the only thing that struck their top flange was that black off-balance switch tripper thing-but a METAL tub ring rail striking the metal top washer flange? Could someone please explain this phenomena to me?
