First Orbital Transmission Maytag's
Tom and I installed the first one of these that I saw run in person [ the customer was giving up on a Frigidaire WCI-61 and a 1954 GE dryer ] After Tom and I saw the pathetic agitation we decided we didn't need one.
MT was having water leaks from the main tub seal all through the 80s the new transmission did not have any thing to due with the increase of water leaks [ by 1990 WP-KM over took MT in reliability in top load washers and of coarse WP-KM were always ahead of MT in dryers in both reliability and performance ].
Overall the Orbital transmission was one of the best improvements MT ever made on the Helical drive washers , the only problem was the orignal agitator, but once they started using the load sensor agitator they finally had a washer that could turn over a large load AND an agitator that no longer destroyed clothing { a shorter stroke is always better for clothing than a long stroke ] And if you really wanted a higher performing MT HD washer I recommend getting the 50 cycle motor pulley, this pulley speeds up the agitation 15% and increases the high spin speed to just over 700RPMs so it is about the same as a new SQ TL Washer.
