In this issue:

1) Repairing the Whirlpool/Kenmore washer gearcase, Part 2
    (longer than usual, but I wanted to get this to you in one issue)
2) Subscribers-only 'Two or More Ship Free' sale still going strong


1) Two issues ago, we talked about removing a Whirlpool-built 'direct
drive' washer gearcase (transmission) from a washer for repair. While
this isn't a really common failure, I am seeing it more often these days.
That said, I still feel that these machines are the best washers for the
money these days.

This issue I'll run through a few tips on taking it apart and replacing the
'neutral drain kit' #388253 which includes the only internal parts (the trip
lever spring and spin pawl - gotta love plastic!) I'm seeing fail on any kind
of regular basis.

First of all, don't let this job scare you - it's really not hard at all. It can
get a little messy if you're not careful, because it's easy to drop one of
these with the cover off and dump the gearcase oil all over the floor
(don't ask me how I've learned that!) But you'll only do that once... <grin>

Tools needed:

5/16'' socket wrench
external snap ring pliers
scraper or 1-edge razor blade
5/32'' Allen wrench
Degreasing solvent and rags
small block of wood (if clamping in bench vise)

Parts & materials (Whirlpool part #'s):

388253 Neutral drain kit
350572 gearcase oil (or 15 oz of most any high grade 80W-90 gear oil)
285352 input shaft seal kit
285753 coupler kit

Before we get started, a couple of notes:

Replacing the oil in these units probably isn't essential when doing this job,
but is a good idea, as is replacing your car's oil filter with an oil change.

Fine metal filings and dirt can accumulate inside any gearbox, and even though
there's much less accumulated dirt in a washer gearcase than in your car's engine,
cleaning it and adding new oil will help it last as long as possible.

I never disassemble one that's been in service very long without replacing its
oil. It's a good practice, and like the oil in your car, when you compare the
oil coming out with that going in, you'll know it's a smart move.

The factory oil is Whirlpool part #350572. It's pricey at just under $30, and 15oz
of any good grade of gear oil works fine. I buy a gallon at a time at Auto Zone
for around $12, but you can also buy it in quarts many places.

I replace the input shaft seal in these whenever I have one apart, because
that's a pretty common failure and it's easier to do while the gearcase is on the
bench. An easy seal to replace (part #285352) and not at all expensive, this
falls under the 'preventive maintenance' heading.

If you've been enduring my rambling for any length of time, you know that's
a 'soapbox' issue for me <grin>. A little PM has saved me a lot of time and
aggravation over the years, and I've become a firm believer in it.

You should also plan on replacing the drive coupler - at least the section mounted
to the input shaft - whenever it's been removed. Reinstalling a used one isn't
feasible because it won't grip the shaft tightly enough the second time it's pressed
on, and will fail pretty quickly. The coupler half that mounts to the motor can be
left in place if it's still tightly gripping the motor shaft, but most of them I see
aren't, so plan on replacing the coupler, #285753 ( instructions ).

The only exception to this *might* be the newest version with the steel
hubs, but I haven't been using those yet. 'Tried one or two so far, but until
they get the dimensions figured out, I can't recommend them. The current
version is fitting too tightly. But Whirlpool will get it right; they stay with a
problem until it's resolved.

Clamp the gearcase assy in a bench vise by bolting the motor plate back
on and using a small block of wood to help hold it level (I've made a couple
of handy jigs out of plywood and 1/2" running thread, but I do a lot of these).
Then remove the eight 5/16'' hex-head screws holding the cover on. Use a
putty knife to break the cover free.

I usually level the gearcase in the vise at this point, just to make sure the
oil stays where it should when you're putting it all back together, keeping it
off the lid sealing surface.

There's no gasket used, but just Loc-Tite (tm) sealer between the two, and
the covers can really stick. I use Permatex (tm) to re-seal the cover back on.
The Loc-Tite's just too darned expensive. Just thoroughly scrape and clean
the mating surfaces before sealing. Acetone or PVC pipe cleaner work pretty
well for cleaning.

Once the cover's off, remove the plastic spin gear's large snap ring and flat
washer, and lift the gear off. NOTE: Do NOT lift the assy by the shaft once
this snap ring's off, or the shaft and gear assy will pull out of the gearcase
casting. Hard on toes - and floors!

Drain as much of the oil out as possible. You might want to try running it
through a paint strainer if you have the time, to clean it for re-use. Like I said
before, I prefer to just use new oil, but trying that might be worth the trouble.

I like to disassemble everything and drop the whole works into my parts washer,
but you can just wipe it out, too. Not critical.

With the plastic spin gear out, follow directions in the kit to replace the neutral
drain assembly. Its mounting plate is held to the main drive gear with a single
5/32'' Allen screw that also serves as the spin pawl pivot. The trip lever (smaller
white part on the right) spring was broken in the above gearcase, but the spin
pawl (larger white part on the left) also can wear its end off.

If you remove the shaft/rack assy from the gearcase casting, be careful not to
lose the thrust ball and washer at the bottom end of the agitate shaft. These two
parts 'hide' in the lower shaft bearing, down inside the casting and are easy to
overlook. The ball goes in first, then the washer drops in on top of it.

If you pull the assy out, note the rack and pinion alignment marks when
reassembling. A single slash mark on the agitate gear must align between the
two on the rack gear teeth.

The gearcase casting, cleaned and ready to be put back together

That's essentially it. If replacing the input shaft seal, just run a sheet metal or
self-drilling screw into its edge at 2:00 or 7:00 to remove it, and press the new one
in with a 3/4'' socket. Hammer a new coupler onto the input shaft with a socket
extension, fill with 15 ounces of oil, seal the cover on, and reinstall in the washer.

I plan on making this article available as an easily downloadable pdf file very soon,
and will let you know when that's ready to go.

2) A whole bunch of you have taken advantage of me ;-) with the '2 or more ship free'
sale, and again this month shipping and handling are no charge for any two or
more online products, to any US address. But only for DRSNews subscribers,
and only during this month for now. Regrettably, this has to be limited to US
subscribers, as international shipping rates have gotten pretty crazy.

Here's the current list of parts and tools included: Sale Parts . If you don't see
the one you need there, and you're a subscriber, just ask me .

One of the incredible rewards I get from writing this newsletter is the encouragement
you all have been to me over the years. I want you to know I appreciate you, and this
is just one small token 'thank you' that I'm happy to do for you.

Please feel free to send me any other ideas you might have for subscriber 'perks' I can
add for you, and I'll do my best to make them happen. And any suggestions for article
topics and/or manuals are always welcome.

Swing by and check out my new Appliance Terms Glossary Project if you haven't yet -
it's still a work in progress. Here's what I have so far: Glossary
