I am humbled that you reached out for help and that my advice helped you. Like I reminded you. As you post your story of the washer that seemed bound and determined to not wash again, you stuck with it. You didn’t lose faith and tackled everything it threw at you like a 30 year vet of the field! Can’t wait to see the rest of the pics and the video of your born again 712.

>> ...after removing the clamp carefully keep the rubber gasket in position (measure to the bottom edge from >> gasket and above towards upper edge)...spacing needs to be correct for reinstalling the cover properly You might be better off following the Maytag or Repair-Master procedures for setting the top cover spacing when reinstalling. The reason being, when taking apart an old used appliance, you don't necessarily know for sure that whoever had it apart before you re-assembled it correctly. Measuring and duplicating that flawed work propagates (and sometimes exacerbates) any errors they might have made. The actual procedure for tub top cover alignment is pretty simple - either setting measured wood blocks on the top of the basket and pushing the top cover down on them to achieve a uniform spacing between the inner basket and the bottom of the tub top cover, or reinstalling the top of the machine cabinet and adjusting the top tub cover up or down to have the prescribed uniform clearance against the underside of the top cabinet opening. Either way gets you to the same result, and after doing it, is relatively painless. Good luck! |

Finally was able to remove the inner washtub...I used multiple cleansing products to clean the parts as I remove them...also used rust-fighting products to address the rusting areas as I go |

WD40 that helps removing a blocked nut is some kind of legend, if it really worked you didn't had to break it.
I've stopped using such thing five years ago, since then I've never broke any nut, bolt, screw... just need a longer wrench for more force, heating/freezing helps a lot too a it breaks the rust. |

Yes old washers can be fun to take apart, overall the washers tubs etc look to be in pretty good shape, Have you located a replacement transmission yet, the agitator shaft is far too rusted for a long lasting repair in the water seal area.
There are still orbital transmissions around and then you can upgrade the washing and rinsing performance by using a Load-Sensor agitator and if you further upgrade by using a 50 cycle motor pulley and belts you will have a pretty decent performing washer.
Thanks for all the great step by step pictures of your rebuild this helps others save their vintage machines.

The top tub bearing should only have turbine oil used, lithium grease is too thick, the brake should have transmission oil in it only.
If you don't replace the transmission you are doing a lot of work for a washer that is only going to run a year or so at best till you have water leaking into the top spin bearing or into the transmission.

I would NOT put grease on the bottom OR top of the water seal, to install the seal to the tub use a little diluted liquid detergent and it will slide right into place.
No grease or other lubricants should be used on the carbon ring.
Putting a 2nd old style agitator seal under the new lip seal may push the lip seal out of place or the pressure from the bottom may quickly destroy its effectiveness,
Good luck, John L. |

Harry - I commend your efforts on rehabilitating your Maytag. Sometimes you just need to dive in to get the job done, and having several here on the forum helping along the way isn't a bad thing at all. :)
I'll echo John's warning about adding oil to the stem seal. The newer Teflon style stem seal kit (both the A4298 version through 1996 and triple lip center seal version post August 1996) is not meant to have any lubrication added to "seat" the seal, instead Maytag recommends that the washer be set to spin for about 3 minutes or so after assembly to break in the seal. While access to the older style seals is limited these days Maytag went back and forth in the 80's on adding oil or not adding oil to the stem seal with a handful of design changes. When they did they recommended using the transmission oil (similar to a 60-70w gear oil) vs. center seal grease (similar to white lithium grease).

Thanks John L. and Ben, I actually followed that bit of information from a Maytag washer Appliance Repair Guy video on YouTube. (Should I remove the grease???) And, John L. please let me know if you come across a possible replacement...I'm looking |

When I replace the stem and boot on dc washers I usually install the old style centerpost seal as well. The only time I don’t is when there is the white clip on the top of the orbital trans. So far, I have not had any issues with it and the lip seal on the new stem is potentially iffy by itself. I’m definitely not trying to contradict you John by any means but this has worked for me on many, many repairs. I just don’t totally trust the new lip seal, esp if there is any slight defects to the trans shaft...
