I always appreciate, celebrate and save these wonderful How-To threads. Guy, thank you very much for doing and posting this. This is a project I actually might be able to do with my very limited tech skills.
John, I agree with your comment about how easy it would have been to use a two-speed motor. But wasn't the issue always that, with a 2-speed motor running on SLOW, the Filter-Flo stream wouldn't have enough momentum to make it into the filter pan? Even I, Filter-Flo lover that I am, recognize that the FF system was mostly BS that used way too much water, but I love those filter pans and I don't think there's a better washing machine for people with Golden Retrievers.
What I wonder about, and never thought about until I joined this site and saw Mr. Seeger's amazing GE AW early Automatic, was WHY, for God's sake, WHY didn't the engineers in Appliance Park use THAT machine (with its Rim-Flo that might not have needed a forceful stream, it's Frigidaire-fast spin speed and it's wash-board solid tub) as the paradigm for their Latter Half of the Twentieth Century models?????????
They went back to the Rim-Flo when they Borg-assimilated Hotpoint washers, but they quickly dumbed-down those machines when Jack Welch and his merry band of bean counters took over. Apparently white goods didn't please the stock-holders as much as nuclear weapons and dirty finance.
