Actually on second thought this one is better and a bit cheaper...

Oh Robert - you crack me up!
Before I put through the order - what size is the mechanism support nut size?

Ben
1 1/2"
so the tub nut and mechanism support nut are the same size?

No, tub nut 1.5", mech seal/support nut 3.0"

for the spin bearing you can use an SKF 6006 2RSJEM. You have to pull the race-way covers off and flush all that blue factory grease out and you will have a perfect replacement!
Hopefully you have a spanner-nut removal tool! OY!
Speaking of hope------- I hope the tub & nut assy. is o.k.

Ummm...
When Roger had the same issue with his Unimatic, it was because the nut was not tight enough. He tightened the bejesus out of it (hit the wrench with a hammer a few times) and made sure the zinc washer underneath was very securely bent-up, and that did the trick...
That may not be the case with yours, but I was remembering that...

Thanks for the sizes Robert - that was exactly what I was looking for.
If I remember reading correctly there were two sizes used on the mechanical seal/nut assembly - a switch around 1957 or so - associated with the seal change? There was that wrench that had the two sides to it...
Steve - thanks for the bearing number. Came up in Grainger with two hits (two different sizes), may need to inquire more with the gang in tech.
Nate - I was wondering about Roger's Unimatic. Was his bearing shot as well because I do remember the story of you guys putting it back together.
Thanks again everyone - I'll hopefully have some time to work on it next week.

I don't think that bearing is a problem. You'd know it, when the spin bearing fails in a Unimatic it makes a very loud roaring sound when the machine is up to full speed. First thing to do is pull the tub and check the Nut and Seal assembly.
Roger's unit
Hi Ben,
Roger's was noisy because the nut came loose from the seal over time because the nut wasn't tight enough when we reassembled it. When it really let loose, it started leaking oil out of the top of the mechanism.
When he redid it and hammered it tight, and was extremely careful to solidly bend-up the leg of the zinc washer, everything was perfect and it spun flawlessly ever after...
We also had thought that it was a snubber issue. It did have a bad bearing when we first got it, but that didn't affect the spin balance or make any intermittent noise at all--instead, it sounded like you were standing in front of the air intake on a jet engine when you had the lid open
. Replacing the bearing made it spin silently, but the noise/rattle/imbalance issue continued as long as the nut was loose.
Hope that helps
Nate

We did the same thing on Ben's machine in December, Nate. Bent up the zinc lockwasher and everything. It was pretty loose and we thought we'd solved the problem but as it spun absolutely perfectly but now here is the rattle again. So strange...

Ben,
I have been too busy lately to pay much attention to the forum but am doing some catching up tonight.
One thing that made noise on my washer when it spun was the capacitor. It had been replaced and the replacement was much smaller than the original so they had filled the cavitiy-are you ready-paper towel wads and some corks. I redid that so the capacitor was stable in the holder and eliminated quite a rattle. Mine did sound like a train- like Nate said- when it spun because of a bad spin bearing but a new one fixed that too.

Well, hmmph. Maybe the spirit of my evil '61 Kenmore is on the loose again... ;-)

I love that capacitor story, Roger. Might as well have been "The capacitor didn't fit, so they'd filled the cavity with metal filings and diesel fuel."
Sheesh.

Of course...
...you could always use one of these to eliminate the spin noise, Ben--shaving several hundred RPMs off the spin speed seems to quiet things down ;-)

Quick Update: few days ago took the capacitor cover off, and did notice a small piece of cardboard shoved in there to eliminate a previous rattle issue. I shook the tub and had the same issue. Waiting for the tub wrench - will keep you all posted.
Nate: SMACK!

Nate, have you been working out? And shaving? Woo Woo!
Well...
...I didn't know if the long hair would go over well, but thanks! ;-)
