I cannot believe the entire pulsator shaft is missing???? This picture below I took about five years ago shows the entire Unimatic Mechanism taken apart. The red star in the lower right hand corner points to the bottom of the agitator shaft. With the large round column machined to the bottom of the shaft there is no way the agitator shaft could be pulled out of the hole in the center of the spin shaft, it would have had to have been sheered in half! I have no idea how something like this could have happened, these parts are as strong as if they came out of an Army tank! Looks like I’ll be using the mechanism from the other machine for this restoration.

If the pulsator shaft was not removed by hand: 1) Then the oil seal failed and water did get into the shaft , the shaft froze in the bearing , thereby not letting any water down into the mechanism but when the pulsator nut was removed the shaft being weakend through rusting snapped inside the bearing of the spin tube. 2) The lady was addicted to Oxydol and the pulsator, nut, shaft and boots were dissolved away by the Oxydol! Simple Boom Boom Done. |

Dang Greg! I forgot about the film strips! I would have loved to have seen them. I totally forgot. You have to have another convention in the next few weeks! Brent |

Well I have no idea how the pulsator shaft tragedy happened, but soon it will be just a memory. Brent there was no other parts, the machine was found just like the picture above in post# 73383. Bryan I learned this stuff by reading the repair manuals and going in and getting my hands dirty. Made some mistakes along the way, but if there is a will, there is a way. Tonight I took both mechanisms and took the best parts from both to make one good one. The start switch was stuck on the good mechanism, when I tested it with a tester cord, it started to smoke within about 20 seconds of running. That's a tell tale sign of a motor that the start windings are not kicking out of the circuit. In a Unimatic that usually means that the centrifugal plunger is stuck and cannot move outward via centrifugal force. |

Rick, good observation. Actually the little hole in the plaster is old; it’s from a Kenmore tranny a while back. Not a big deal in the workshop. Testing a Unimatic on its side wouldn't be a good idea anyway. Brent, I know each and every Unimatic Mechanism part inside and out now, it makes it a lot easier to have it all stored in long-term memory. Thanks Steve, I have a bunch of those bearings myself. We have some really great bearing shops here. Your oil test idea is a good one! I would put in only 5oz or so, just enough to fill the bottom of the oil pan and wait a day. If everything is dry then add the other 20oz. Be warned though, sometimes the oil seal holds until you run the motor, then it decides to fail. |

Steve, one last thing I just thought of. During your oil seal test you need to make sure that the motor end bell is installed!! Because the oil seal has 3 parts: 1. the main seal pressed into the oil pump housing 2. the face seal that slips onto the rotor shaft 3. the spring on the rotor shaft that holds that face seal tight against the main seal, but lets the face seal rotate with the motor. If the motor end bell is not installed, there might not be enough pressure on the rotor to hold #2 and #3 against #1 and then the dreaded drip, drip, drip. |

Would there be a way to use the motor and bell cover off of the other mechanism, or is there a problem with that motor, rendering it non-operational? Hi Austin, I am going to use to better end bell, but both motors winding cases are in perfect shape electrically, one looks slightly better than the other, but both are perfect. While all parts are interchangable there is no reason to take the extra time and effort to switch the motor winding case itself. I'll save the extra motor case when I breakdown the "bad" mechanism for parts during my cleanup phase after the washer is reassembled and washing away. |
