All Maytags have that groove it is supposed to be there I used to wonder about it when i first saw it also.You just need to emery cloth down the agitator shaft and you should be all set. |

Uhh...Kevin, is that your washer you've been using all along or did you get it from somebody else?
Somebody's been washin' with hard water, cold washes, and no phosphates. The bottom of that outer tub is really bad. I know you just started working on this machine and maybe it wasn't yours to begin with, but that's pretty bad. Everybody's got different standards, but I wouldn't want to wash in that. If you really want to restore your machine you're going to need about a gallon of CLR and vinegar, a scrub brush and lots of elbow grease. If that tub bearing's not too bad off and it's the old style with the fat bottom that has the wicking inside of it, I'd try and reuse it. Don't wash it in water. You don't want water in the wick, if it has it. I wiped the outside of the rubber clean and wiped the inside of the bronze with a lint free cloth moistened with some kerosene. Then wipe it out again with a clean part of that cloth. It has to be perfectly clean before it's reassembled. I bought a new metal spin sleeve, gave the inside of that bronze a good coating of turbine oil and put the new spin sleeve inside the bearing to see how the fit was. If the bronze isn't too worn a new spin sleeve and a lot of turbine oil will restore the bearing. The old bearings are a lot better because when the bronze gets hot it sucks up the turbine oil out of the wick material in the bottom of the bearing. This type of bearing will way outlast the new style. Turn the bearing upside down and pull the rubber back away from the bronze insert. Stick the Zoom Spout Oil tube down in there and squeeze. You can watch the wick soak up the oil for quite awhile if it is dry. When it quits sucking up the oil so fast it's probably about full. Follow Redcarpetdrew's thread #25520 in the forum archives to finish. If you don't have the old style tub bearing, I've wasted a lot of time telling you about something you can't do. If it's the new style just get another one. Since your washer's a 712 it's probably the old style. Hope it's salvageable. You can start on a lot of these things before you try your transmission rebuild in the spring. See if you can find an old agitator shaft seal. It will help. |

Thats a brilliant idea to mark on the tub where the channels are on the transmission shaft. I will have to use that when putting the machine back together! Thanks again for your help! |

I see what you're talking about now. I couldn't see your video before. I'm not sure. That set screw has to bite into the threads to lock the wash basket to the transmission. I suppose you could try a longer set screw. It has to bite into that neck but not bind the agitator shaft turning inside the neck. The set screw has to make a dimple in the neck so the stem mount won't move. Stress is put on that set screw dimpled area when the washer goes out of spin and the brake engages to stop the tub and when the machine is agitating, the tub is full of clothes and the brake is holding the tub to keep it from indexing.
When you got the washer did you put it into a spin and then lift the lid to see how quickly the basket stopped. If the break was getting dry it would stop the basket more quickly and put more stress on the set screw, especially if the stem mount and spanner nut were not tightened enough. This is usually accompanied by a loud squeal. When the brake gets dry from lack of oil it will squeal. Sometimes the stem mount will be tightened more or less to avoid those flutes on the side of the neck. When the stem mount is tightened less the set screw gets more stress than when it's tightened more. If the set screw wasn't tightened enough or it was too close to a flute and slipped over into the flute during a brake, I suppose it could spin around the neck and carve out a groove. But since the stem mount is reverse threaded and I believe self tightening it would probably be more likely to happen during agitation indexing, moving the tub further and further until it carved a groove all the way around the neck. You can see me pouring some oil into the break on Thread #37873 (Avocado Maytag Set). Maytag guys; am I right or wrong or somewhere in between? |
