Part 7

I had a look at the UK service documentation which seemed much more detailed than the Australian version so I thought might be helpful in rebuilding the machine and getting it running again. It is contained in the attachment, I think your current issue about bearings my be covered towards the end of the document (it is 46 pages!). There may be some detail differences to your machine as these machines were constantly being updated during the production of the 3224 at least, but hopefully it will be of assistance

Oh wow, thanks for uploading those! Such a great resource.

The part 7 spare parts section - the cover shows something that confirms a memory from my childhood that I have long puzzled over.
As a child we always had Hoover upright vacuum cleaners, always bought from the local Hoover store, Westwoods in Frankston.
Even bags and belts were always bought there. I always enjoyed going to the store, there were interesting displays and the people were lovely. It was a very small store, just a little counter and usually one or two vacuums, one polisher and one washer on display.
One day there was a Keymatic on display, but it wasn't badged Keymatic, it had only a number - a 3 digit number, in the 400s. 420? 450? It was right towards the end of Keymatics, early 1970s?

There in that parts catalogue is the answer - the catalogue is for 3224, 3226, 3226A, Mark 4 and..... 425! The mystery is solved.

When the Keymatic was dropped in Australia (we never had the later, square body Keymatics) it was replaced by the Hoover 455, a unique for Australia model made at Merthyr Tydfil in Wales. Black dashboard with an orange switch for A/B, which was basically spin / no spin.)
That was replaced by an Australian made version, the simplified Hoover 460 and 465. (No dispenser drawer, and no heater on the 460.)

Thanks Vacbear85
Those are so incredibly helpful! I’ll definitely have a shot at the bearings on the weekend. There was a lot of corroded aluminium in the bottom of the drum so hopefully everything is ok. That pin that holds the bearing sleeve on (I think that’s the correct term, the part that has the brake shoe and what the pulleys go on to) seems pretty difficult to remove.

But again, thank you so much! This is so greatly appreciated. I’m surprised there are documents floating around.

That’s pretty cool!

I do have a Hoover 460 which I saved, was sitting outside and probably was going to get chucked. Just needs a pump and the wiring to be sorted.

That pin that holds the bearing sleeve on

In the new downloads, that pin is called the transax pin. (point 19 in section 4.)

I drilled mine out when I pulled mine apart years ago, but the manual says to punch it INWARDS, into the pulsator shaft tunnel. I'd use a parallel pin punch, Bunnings sells sets of them. You would have already removed the pulsator which includes its shaft, so the spin tube now has an empty hollow where you can punch the transax pin. Later you can remove the transax pin from inside the shaft - I'd try using a magnetized screwdriver - and with luck you might even be able to reuse it.
The transax pin should also have a little rubber cap pressed in on top of it, (It's in the parts diagram) I'm not sure of the purpose but I'd just put a little silicone sealant in over the pin, smooth it down and leave it to dry before doing any more reassembly.

The Hoover Keymatic is probably the best washing machine ever made in the history of humanity. Lucky to all who have one!

I just want to ask, why are there two pressure switches?

 

[chestermikeuk]

That's some statement in the history of first automatic washing machines , others will have many different views

The pressure vessel is lower front right of the machine cabinet connected to the sump hose ( hence the complicated sump hose arrangement ) two hoses come out the top of the pressure pot and travel to the fixed on top chassis pressure valves , 2 because it's a Hot & Cold washing machine with individual pressure switches for the wash rinse water levels .

Hoover Keymatic is certainly at least I think a top contender. I wish I had one to try out and play with. I don't entirely have a preference for the keymatic concept, but the rest of solid with great washing and rinsing.


I'm still confused though, couldn't one pressure switch do the job and sense water only in one location? In the US Hot and Cold connected machines have only on pressure switch, though to be fair like the Maytag Neptunes had more than one set of contacts within the pressure switch for varying wash and rinse levels.

 

[chestermikeuk]

Yes , didnt make that clear in last post , this slope front Hot & Cold Keymatic has different water levels for wash , then rinse on individual pressure switches .

The later Keymatics had one pressure switch with multiple levels low medium & high

It's certainly a heads scratcher at times to work on if you think this series had 4 timers and six wiring loom upgrades for two models over 5 years of production
