First let me say that of all the sites I've browsed looking for info, this one seems to be the most informative and helpful, and I'm hoping you can help me.

I've got a Maytag washer about 10 years old, model no. LAT9706AAM, and my wife has noticed an occasional leak for sometime which I thought was around the drain hose.

As it turns out, when it got a little worse I did some inspecting and found that the leak was coming form the bottom of the outer tub. I did a little research and purchased a bearing, seal kit, and spanner wrench and started the repair. I figured if it's the tub seal that's been leaking for a while that the bearing might possibly be ruined also, and sure enough it was.

I've got washer disassembled down to the bearing but my problem is that I can't remove the inner sleeve from the transmission shaft and I don't want to damage anything trying to force it. I know it's seen water because there was rust around the upper edge of the sleeve that I had to remove before the outer (brass) sleeve would slide up off of it, and I suspect that there may be some rust inside the sleeve also that is making it difficult to remove. I don't know if this is a common problem with a job like this, but if you can help me in any way I would greatly appreciate it. Thanks.

Common problem indeed. All of us will have there favorite sleave splitting instrument. Mine is an old beat up Stanley screw driver. You will see a groove in the transmision. Split it right down that groove being carefull not to hit the trans. Clean the surface up a little bit prior to slipping the new one on and your good to go!
I don't see a grove, there are threads above the sleeve where it slides down over and the sleeve itself butts right up against the transmission case with no gaps between. The sleeve itself is 2-1/2" long so I imagine it would take a while to split it from top to bottom, but if that's what it takes. Thanks for the help.

That got it! I didn't realize that that sleeve was cast. I used a cold chisel after about 6 whacks it cracked about halfway down and broke, then I got another bite on it and finished it. Still there's no groove though, just a smooth shoulder that it slides down over. Anyway, thanks again for the help, I really appreciate it.

OK, I got this thing back together and ran through a small load cycle to test it out and it's leaking worse than before.

I thought maybe the seals needed to "seat" themselves, so I drained the water, ran a couple spin cycles, and tried it again. Still leaking. At the moment I'm taking a few to think about it and not get myself too excited.

One thing I'm wondering about, the stem seal (carbon one) was pre-greased when I got it but the top seal (around the shaft) was not. I put a small amount of lithium grease on it, in the channel between the rings, and I'm wondering if maybe I shouldn't have. Any suggestions?

Alright, I cleaned up the carbon seal, put back together and sure enough, it still leaks. I took it apart again while it was still wet and was able to determine that it’s leaking where the seal slides down onto the small flange on the bottom of the outer tub. I took the seal off, cleaned both it and the tub again real good, reassembled and tried again, still leaks.

At this point I don’t know what else to try. I did notice that the rubber on the bottom of the seal, where it meets the tub surface, is very shiny and slick. I’m wondering if I would rough it up a bit and spread a thin layer of silicon on it and the tub might that work? Maybe I just got a bad seal, I don’t know. The bottom of the tub around that small flange seems to be in good shape so I don’t know what else it could be. I’m just glad I’m not doing this job for someone else cause I would’ve got fired a few days ago.

I'm not sure how to attach more than one photo to a post so I guess I'll have to make several posts. I've gone over the seal and I can't find any kind of tears or punctures.
Here's the tub:

I took a couple of side shots on the seal because it does seem to be a little warped, but then it's the only new one I've seen so I don't really have a reference. It mounted tight enough that it seemed to me it should have sealed but maybe that's enough to make it leak. Here's the shots:

From all the pictures, nothing obviously wrong with the seals.

That little uneven look in the last two pictures really shouldn't be an issue, you have about a 1/4" to 1/2" lip that it slides down over.

When you pushed the spring loaded bellows part of the seal onto the tub lip, did it seem to seat down evenly all the way around and a good tight fit?
Yes it seemed to. The very first time I put it on I used a small amount of Liquid soap because it was too tight, then I tried cleaning that off and just wet it with rubbing alcohol and slid it on there before it dried.

You didn't by anychance take the allen head set screw all the way out of the top part of the mounting stem and forget to put it back in???
No, I remembered each time.

Did you make sure the top, (mounting stem), portion of the seal was screwed down all the way? That top rubber seal in the mounting stem has to be down below the grove in the agitator shaft to seal around the agitator shaft.
Yes, it's screwing down to where it should be.

1)Might you be putting the seal on upside down? In your last picture its orientation is upside down if recall correctly. The top part as it is pictured (the end with those two parallel threads embossed in the rubber) is the end that goes down over the tub. The other end has that carbon O-ring that you need to not lubricate. I’m guessing you are doing it correctly since it is pictured upside down I have to ask…
Yes it was installed correctly, I only inverted it to show the uneven bottom edge.

2)I think I see rust inside the rubber boot. Are you installing both a new Tub Bearing Kit and a new Under Water Seal Kit? Two NEW parts, right? Not reusing the Tub Bearing gasket (your last picture – that’s a NEW part, right)?
Both parts are new, the rust is light surface from where it leaked the first time I installed it. You should have seen the rust on the old one when I took it off.

3)In your first picture the two carbon O-rings sure don’t *look* very clean. I take this picture was taken after uninstall and before you had re-cleaned?
Yes, I pulled them out and took pics before cleaning them again.

I'm going to try another seal and see if that takes care of it, the old (new) one is toast now since my son knocked it on the floor (accidentally) and chipped the carbon ring. I hauled the wife and kids down to the laundrymat today to wash since it was piling up. Gotta love those family outings!
