Hoover Keymatic 3224

This is really a faboulus machine. Chestermikeuk has one. I wanna know if he has gotten his to work yet. Would be fun seeing clips of it if he please could upload some.

I had one myself but the program died and i hadnt the time to repair it. Plus i dont work with recycling machines anymore, so getting parts are not easy. I gave the machine away to another collector. He hasnt gotten it to work yet, seems some cables are in very bad shape.

The motor is however in good shape. Pulsator had a "knocking" noise sometimes. Maybe the bearings, who knows. When spin the machine was not very loud. Except from when my girlfriend washed a half load and it went unbalanced. The machine vibrated so much it switched off. Boy, she was pissed!!!!

She is used to the Siemens that takes forever to balance the load.

Technically, this machine is a nightmare. Lots of hoses and such. The belt for the pulsator is almost impossible to get right.

I know Foraloyisus has one too, but he has the second generation. I think his has less hoses and such.

Isn't that photo the machine that was on Aussie ebay a few weeks ago?

The pulsator belt is easy to set up. The motor is adjusted to suit the tumble belt(the ordinary v-belt), then the idler pulleys are adjusted to tension the spin/pulsator belt(the round section belt). The spin belt drives the spin pulley on the back of the drum, clockwise drives the drum (spin), anti-clockwise the pulley idles backwards due to the one-way clutch inside the pulley, but if the wash programme is a vigorous one, the pulsator solenoid clutches the pulsator to the spin pulley, causing the pulsator to turn in the opposite direction to the tumbling drum.

The Keymatic has only two cables, the drum assembly is suspended by a cable, and the drum brake is engaged when the door is opened, operated by a cable.
If the suspension cable breaks, the drum will drop with a "bang" and sit on the floor. Machine will not go at all.
If the brake cable is out of adjustment, either the machine will not operate at all, as the door switch depends on cable tension to engage; or the machine will operate perfectly except the spin brake won't work, and that only operates if you open the door during spin.

Noisy operation of the pulsator is normal - the pulsator doesn't have true bearings, just bronze bushes. The brake drum on the drum shaft acts like a megaphone, amplifying noises such as the clutches scraping, and any slight rattle of the pulsator in its bushes. The pulsator clutch spring always scrapes (normal) which adds to the symphony.

The second generation machine is mechanically identical - the only changes are trivial, such as a round progress display instead of the "time line"; a stainless steel door liner instead of white enamelled steel; plastic idler pulleys instead of cast iron. The hoses are identical.

re; cables. Its the electrical cables that are in bad shape. The suspension cable is ok. i didnt know the hoses was the same for the second generation.
