Carl you must be pretty handy to have put so many repairs into this washer but I think I would pull the plug. If you have had this many seal problems you should be sure that you are using enough detergent, you can tell if there is any buildup of mineral deposits in the outer-tub of your current washer that you either need a water softener or better or more detergent.

If you want a machine similar to the Amana get a new Speed Queen Top Load washer while you still can or if you want to do something much less expensive [ and also since you are so handy ] Get a 5-15 year old WP or KM Direct Drive washer, one of the many good things about WP DD washers is that they are virtually unaffected by hard water when it comes to the main seals.

Carl and Andy, I don't think that I was being too harsh when I suggested that there was no good reason to fix this washer again, EXCEPT for one reason that Carl gave in your first post about this washer being built in the town you live in.

I thought more about this after reading some of your following posts and when I think about the 100-200 appliances we have saved for our museum project that not one of them was built in Beltsville let alone even Maryland, so I can now more fully appreciate why you would like to save this washer. { and I still think that it is the only good reason to do so ]

You asked about using SQ parts to make a more durable repair, I know that the outer tub is very different [ the center seal area is raised an inch or two ] so I suspect that you would basically have to use almost the entire SQ guts inside the Amana cabinet at which point it would be only 1/2 built in your town, but since this design did originate from SQ originally [ not Maytag or Amana ] it would be sort of the ultimate Searcy built washer.

If you wanted to fix this washer using new factory parts and you wanted it to last longer than 3-4 years I would consider doing the following. Take the aluminum  hub that rode inside the lip seal to a good machinist and have it turned down and a Stainless Steel sleeve installed in the wear area, doing this would likely make this seal arrangement much more durable.

I was at the Maytag sponsored training meeting approximately 15 years ago when this STUPID lip seal running on plain un-coated aluminum hub lubricated with Vaseline under water in the outer tub of a washing machine was introduced to us. I told the MT reps and the at least 40 techs in the room that this would likely be lucky to last 5 years and maybe a lot less. At another service meeting around this time when the MT Neptune FL washer was introduced I again told the entire meeting that the main Water Seal would not be durable, at least this time MT did change it for a better design but it took about 5 years to do so.

I was always very vocal at service meetings asking questions and offering my opinions, some trainers probably didn't like having me there, , LOL, but when meetings were announced they usually always gave us several different dates that we could attend, and we would usually get calls form a few other local dealers asking which meeting that John was going be at so they could be there also. My old boss Bob from the MT dealer where I started always wanted to be at the same meeting because he said I always learn so much more if you are there.
