Thanks guys for all your support!

I Have discovered what was wrong with the motor , it has an internal starter switch that was stuck on and so overheating, after removing and cleaning it it now starts and runs silently, however in assuming some pulleys were seized i oiled them. This machine is very complicated, the motor rotates in a certain direction and causes the drum to rotate at tumble speed , but when going into spin the motor reverses direction instantly which causes the drum to speed up into spin but in the same direction it was going as tumble but has some sort of clutch , but i think i oiled it so now it tumbles normally but then when going into spin it squeals and shrieks so i will have to clean off the oil (any ideas), but apart from a new door boot and poss rope type belt it seems ok. I will try a local shop it has ancient things even reconned 119s juniors in the window!

speak soon

Hi Richard

Squealing noise - don't spin the machine without water in it - there is a ceramic faced seal inside which MUST be wet or it will wear out.
Other ideas for the squeal - disconnect the belts. Set the machine to spin again. If it is quiet, the squeal is in either the drum, the idler pulleys (where the spin belt turns the corner), or the clutches. (The clutches are on the back of the drum, not in the motor.)Possibly the drum brake - there is a silver brake drum between the pulleys and the wash drum. There is a cable from the door switch to a lever on the back,the lever has a small brake pad which rubs on the drum to slow it if the door is opened during spin. If it is out of adjustment, the brake pad could still be rubbing on the little silver brake drum during spin.
If it still squeals with the belts disconnected, it is in the motor, or possibly the pump.

For interest, here's how the clutches for wash and spin work:

It's quite simple, really. The motor lies crossways under the drum. It has one pulley on its shaft at one end, and a reduction gear at the other, with a pulley on the reduction gear. This means the motor assembly has a fast pulley and a slow pulley. (about 15:1 ratio??? )
The drum has two pulleys on its shaft, each has a very simple clutch between the shaft and the pulley. The pulley drives the drum clockwise, freewheels (spins free) when turned anti-clockwise. So whichever pulley turns clockwise drives the drum.
The pulleys on the motor turn in opposite directions, so if the slow pulley on the motor turns clockwise, the fast pulley turns anti-clockwise. In that case, the slow pulley drives its belt, which drives its drum pulley clockwise, which turns the drum slowly clockwise - the WASH action. The other pulley spins fast anticlockwise, which doesn't drive the drum, it just spins. If the pulsator clutch is engaged, that fast pulley drives the pulsator (impeller) inside the drum, too.

If the motor sudenly reverses, then the slow pulley is now turning anti-clockwise, which doesn't drive the drum, it just idles around. The fast pulley is now turning clockwise, which drives the drum FAST - the SPIN action.
So reversing the motor changes the drum action from slow clockwise to fast clockwise. The drum can never turn anti-clockwise, as any pulley turning anticlockwise just slips.

Chris.
 
Heh. Congratulations on your Keymatic, ricky5050. I remember mine very well.

I have to say, yours are in much greater condition than the one i had, was in. For instance, in the shot of the wires, some of the wires, especially those that went from the keyplate unit, had broke on mine. Therefore it just got stuck on several places in the program and sometimes the fuses blowed.

The machine i had had been stored at my familys house. Almost never used because my mom hated the machine. Then in 2001 they decided to throw it away and i took it home. It worked really great until 2005 or 2006 when the motor broke.

I was lucky and found a motor for it and it worked for a while more. Then late 2006 i noticed it began to stuck on several places during the program. Sometimes it went ok after a while. Other times i had to put in the "spin only" card, remove that. Put in pre wash or rinse to do the rinses.

I felt this didnt worked very well. I sold the machine to a collector here in sweden that had worked with repairing machines. He later sold the machine to someone in Norway because it was so much to do with it.

I hope yours will work better and that you will have a good time with it. This machine IS considered rare in most countries and its quite an amazing machine. If it was made today it would cost millions to buy it (i think)

On another note, Gizmo is right, dont spin the machine without water. Its not very good to do that.

I,m looking forward to more pics and (hopefully) some video clips as well.
 
Nice One!!

Hi Richard, Wow, really glad you won this after missing out on the other recent one!!!Now thats something I have never seen, a 46yr old machine with its TRANSIT brackets in, it looks in fine fettle as well, mine is due a service & spa treatment, it worked fine UNTIL the support wire snapped and the drum dropped smacking the wiring loom case cover, and ripping a few hoses out of their sockets!!!

This wire, (the one you can see attached to the sides under the main spring) runs across and underneath the front of the tub and positions it in the "Tilt" angle...is the weakest link of the whole machine me thinks, I cant believe its soooo thin, rather like a thin cyle gear wire, BUT as Chris says, this machine does bounce around a lot inside and doesnt generally dance on your kitchen floor....

Have you ever seen sooo much rubber hoses etc in a front loader...LOl please make sure you do a simple water test outside after inspecting all the hoses, this beasty pumps so fast you could be sittin in water if it fails...

The weird thing about the boots is I found one black one a few months before my machine turned up, these turquoise original boots are so fragile that I used glycerine on it to keep it as long as I could...(which was until last week when I moved it whilst filming it and the whole thing ripped apart at the top, Am sifting through a load of Qualtex old spares at the moment to see if any fit, will let you know..

Email me your address and I`ll send you a copy of the manual,(and something else I just found that you will need for your other classic) fascinating bedtime reading...Can you tell me the serial number to date it, it looks a later model due to the badge and the newer keyplate...

Enjoy the restore, Mike
 
Hello Richard. It's great that classics like this go to good homes. I hope you really enjoy playing with it.

I bet is sounds quite different from the later square door machines, especially on spin.

Hi everyone thank you for all your interest!
Latest news on the Keymatic!

Well since the clutch squealing, i was advised by a friend to remove the pulleys and very fiddly clutch springs and clean all off the gunk of them, i did this but it still squealed and could not get into spin, i maybe was not thorough enough and will re do the faffy job at the weekend! The squeal is the spin pulley on the shaft as the tiny locking barrels are not gripping enough, there is slight play on this pulley so it may be worn. I did try filling the machine manually in case it went in to spin and cause damage the ceramic disc , but the poor thing never got that far. The motor runs very smooth and quiet. No leaks for the sump pipes but a slight dribble over night from the pump led me to remove its cover clean and seal it, which led to a new drain hose being required as it was very brittle and simply snapped off. a new length was got at halfords though.

The door seal had dropped to bits , so a new one is desperately sort , Chris i think i may need a new spin belt as although it has not snapped it has a nasty cut in it, if i have no luck in the uk i will be in touch with you. Sorry no photos as i did not have memory card in camera, will get some to you asap.

Also my hoover twin tub has just come it looks tiny ! i also won a lovely blue hoover iron too! So i have made my home a Hoover home ! have you??

Cheers Richard
