Default Replacing the bearings on a front-loading washer

Hello,

My 6 year old Kenmore front loading clothes washer was getting louder
during the spin cycle, so I figured the bearings were worn. I tore it
down to remove the two bearings holding the spin basket shaft, and the
forward-most bearing was rough and rusty. Apparently the shaft seal
between the bearings and the wash tub had partially failed, allowing
some water into the bearing. Everything else was in good shape, so I
guess I caught the problem early.

I've ordered replacement bearings and a replacement seal, but I have a
few questions about reassembling the machine:

1) What is the proper grease/lubricant to use in each of the following
places: between the bearings/seal and their metal housings, between
the bearings and the shaft, and most importantly between the shaft and
the seal? I have lithium grease on hand if that would work.

2) What is the proper glue to use for connecting rubber to painted
metal? There is a rubber boot that connects the wash tub to the front
face of the machine for the door to seal against. It was glued to the
front frame in several discrete places around its perimetter, I guess
so you don't dislodge the boot while shoving clothes in the washer. I
need to reglue it.

There's no information in the service manual, since Kenmore sells the
entire rear tub half with the bearings installed as a single unit.
But that is alot more expensive than just replacing the bearings, plus
the OEM bearings were not a very high quality.

Thanks, Wayne

I can't speak to the grease question, but I'd use a little Dow 732 to
reattach the boot. I love that stuff.

Dow Corning Silicone Adhesives/Sealants

Form a tough, rubbery solid in 24 hours at room temperature (unless
otherwise stated). Not for concrete, mortar, or under water (unless
otherwise stated). These products are VOC compliant in all 50 states
as of October 1, 2008.

732 Multipurpose— For sealing, bonding, and gasketing. Bonds metal,
plastic, ceramic, glass, natural and synthetic fiber, silicone resin,
vulcanized silicone rubber, and wood

http://www.mcmaster.com/#dow-corning...alants/=8bxjby

I'd just make sure the paint is still solid after the removal of the
boot. There's no adhesive in the world that's going to work if
whatever it's appplied to is loose.

Thanks for the suggestion--RTV (room-temperature volcanizing) silicone
seems like the way to go. I'll get myself some, although probably not
the Dow 732, as I don't think it comes in small quantities.

As for the grease question, any takers? I'll probably just use the
white lithium grease. There is a concern that it is petroleum based,
so it can degrade rubber, but the seal I am using is marked "oil seal"
so it is presumably a resistant material. :-)

Cheers, Wayne

Ours is maybe 9 years old and is getting noisy too. Where did you find
the bearings and seal? What are the part numbers? -- just in case ours
are the same.

I was able to find online the service manual for my machine, it helped
with tearing down the machine. The job was a very involved, several
hour affair. For replacing the bearings (instead of the whole rear
tub half), the best resource was this long thread:

http://www.applianceblog.com/mainforums/washers/237-fixed-drum-gasket-rear-shell-bearings.html.

As for the parts for this class of machine, they are a 6306RS2
bearing, a 6307RS2 bearing, and a 40x80x10 double lip metric seal. I
ended up getting mine from bearingsdirect.com (no affiliation).
You'll also need a replacement tub seal since you have to split the
wash tub halves. Plus the materials I asked about in my OP.

I got the bearings today and the rear tub half is now reassembled. It
spins quietly, yay! Now I'm just waiting for the tub seal and bottom
supports (shocks), then I can reassemble the machine and see if it
still works. :-)

Cheers, Wayne

Thanks for that, Wayne.

What was wrong with the shocks that they needed replacing too?

BTW, when we had the control module replaced under warranty, the service
guy said that replacing the tub is a two-person job costing almost as
much as a new washer. I hope that I can manage the job on my own -- as
you did -- but I'll need help to get the dryer down from on top and put
it back.

One of them was cracked where it attaches to the bottom of the case.
I decided to replace them both for good measure.

Sears would have done it for me for $129 flat labor plus around $170
for the rear tub half. At the time I wasn't 100% sure what was wrong
with it, so I decided to disassemble it myself.

Yeah, I could have used a second person for moving the stack out of
the closet, unstacking the dryer, and then moving the washer to an
area with workspace on all sides.

After that you probably won't need a second person. I disassembled
the machine the way the service manual suggested, not sure if the
thread I referenced follows that procedure. The drum assembly is very
heavy and most of the weight of the washer, because of the tub, metal
basket and the concrete counterweights. The procedure involves
disconnecting everything from the drum except the top spring supports,
tipping the washer on its back (watch the drum, it sweighs now),
disconnecting the springs, and then lifting the case off the drum
assembly. That way you never have to handle the full weight of the
machine.

Cheers, Wayne
