Finished.

Now I understand the front 'bearing'.
The front of the drum, runs on and is supported by, felt pads.

How do I upload a video?

Great job, Peter. Another vintage dryer lives to dry another day.

Videos can't be uploaded to this site. You can upload a video to YouTube and then post the link in this thread.

Ah thanks, I'll try dropbox then.

Here are 3 dropbox links , -- if they work.

Almost feels wrong to keep using it. Like it belongs in a museum.

BTW..

Thanks for the help chaps. I couldn't have done it without, and it may have to have been scrapped, which would have been terrible.

So thanks again.

Hi Peter.

Thanks for updating us with the repair - so pleased that the belt was suitable and that you've got the dryer doing it's job again.
Quite the tear down to replace the belt and interesting to see how that range comes apart.

Also interesting is seeing the internal arrangement of the 37405 (and by default the 37406, 37415 and 37416). Always liked the filter behind the removable segment of the fascia.

You asked about the 37406 Sensamatic ....

.... somewhere about its construction there was a sensing rod/pad/area, but I have no idea where it was on the 37406.

Many years ago the late Gary Tibballs (electron1100) managed to save one of the drop down door Sensamatic prototype machines (I think its machine P12), from the range before your machine.

On this model (TD400A), there is a sensing rod applied to the front of the machine which, when the door is shut, sits in a aperture beneath the filter and door air vent. The air passes over it and the sensor detects the moisture - the load dries and when there is no moisture detected anymore, the machine turns off.

The machine is programmed, rather than timed - select your programme, press start and walk away and the machine will turn off, once no moisture is detected in the load.

 

[matchboxpaul]

Other manufacturers build the sensor into one of the drum paddles, whilst others (Miele for example) designed an array of sensing pads into the door, which the drying load and air pass over.

 

[matchboxpaul]

The 37406 was always rare to see out and about - I only ever saw that model in shops and, as far as I know, one has never surfaced on ebay and no one has managed to save one.

The replacement model (37416) was equally rare and although one of these has appeared on ebay (many moons ago), as with the 37406, none is saved.

'..... .and it may have to have been scrapped ......&#39

When the time comes, hopefully it would find a new home amongst us - but not for a while yet!

Thanks again for the photos of the repair.

Happy drying
Paul

Hi Paul,

Thanks for all that information. The Creda reversair I have, is quite simple then, in that the timer is just a mechanical clock I think, with a spring. You wind it up, and it counts down.

What I don't understand, is what causes the drum to reverse its direction of rotation. That happens independantly of the clock timer as it is counting down.

My crude guess, is that the large blue capicitor next to idler arms under the drum, is involved; thus creating some kind of 2nd timer circuit, that perhaps reverses polarity to the drum motor which stops momentaraily and resumes in reversed rotation.

If it packed up, I'd like to know how to fix it. I guess a first step anyway, would be that capicitor. But hopefully it won't pavk up.

Anyway, it's been used properly since repair. Weather's so bad that plenty of clothes have been in the dryer. Lol.

Cheers.

@sipj

Picture3 of your last set shows the back of the dryer and if you look above the heater there is a metal lever with a threaded screw and on there is I believe a small bakelite block which is also threaded that travels up and down the screw pressing the metal lever as it reaches the end. When it presses the lever it switches the motor direction

 

[slpj]

Thanks ozzie908.

I've just had a look at other pictures of that, and now I can see it.

Pretty clever in its simplicity. Next time I pull it out, I'll take the back off and inspect it for wear.

Thank you.

Creda Reversair

Great work Peter , good to see another vintage classic Creda saved from the scrap, also good to see the airflow venting box and how the airflow is directed up top and over back to vent out the hot air.

As hot air always rises it always seemed more logical to offer this concept, Creda certainly were ahead of the game with their products,

Thanks for sharing , Mike

Interesting to read. I have a Creda/Electra 37276 3kg tumble dryer, very similar in appearance to the Creda Compact 3 in the pamphlet above, with a flap-opening action. Owned since 1980, it has suddenly stopped rotating and I suspect the belt has gone (but the bearings sounded OK before this happened). I can't figure out how to take off the casing (I have removed the obvious self-tappers). It looks one-piece, in contrast to more recent ones, which seem to have panels. Could anyone advise? Ideally, if someone has the service manual?

 

[slpj]

Hi dluc,

Have you managed to get the belt replaced?.

Did you see the service manual above? It mught help you too.
