Gotcha you little sod!

ila_rendered

June 1989 for this part

ila_rendered

Under the top cover lay lots of pretty lights

ila_rendered

But also this securing rod

ila_rendered

Which once removed separates the back part from the front

ila_rendered

The incoming wires can be separated

ila_rendered

And I undid this screw

ila_rendered

Expecting wonder and merriment but go utterly nothing again so I replaced it and decided to leave that be, it wasn't dirty anyway

ila_rendered

Back to the pretty lights

Where the devil were we? Ah yes, the pretty lights! They are daisy chained together and lift out of the holder

ila_rendered

The reset switch is also part of this loom

ila_rendered

With the bar that holds everything together at the pivot point withdrawn, the bottom part of the first bit falls away

ila_rendered

Then the flexible joiner piece moves backwards, and once thats gone the top motor cover lifts off with its bits of filthy foam

ila_rendered

2 strengthening brackets pop out of the flexible cover

ila_rendered

And here is the motor itself!

ila_rendered

This cover lifts off the top and reveals the worm drive that the motor uses to spin the foam rollers

ila_rendered

Underneath, the plastic sleeves that the foam rollers clip onto pull off the inner drive axles

ila_rendered

Then the motor and drive assembly lifts out the top of the housing

The whole thing wasn't too terrible, but was clagged up by the powder that had found its way inside the assembly

ila_rendered

Which was brushed off, and that was the end of the Kobosan head for now! Onto the power handle!

ila_rendered

The top of the handle comes off the switch assembly for when the cleaner is in use strapped to your shoulder with the tools

ila_rendered

The handle grip slides off the metal part

ila_rendered

These 2 screws cover the wiring internally

ila_rendered

And reveal the inner secrets once removed and the cover falls off

ila_rendered

Nice simple connections, although I'm not too sure what the black box is for

ila_rendered

Either way, the mains cable unbolts, and the torn cable exit grommit can be removed

ila_rendered

The black box contains a resistor, and connects the handle to the live terminal, which seems a tad odd to me, but the person who had it put there was probably far more qualified than I am in such matters!

Some wiggling and forcing of the release button inside the surface of the handle has the second metal part out

ila_rendered

The plug end is held in with this bent bit of metal

ila_rendered

once released it withdraws, bringing all the internal wiring with it. At the other end, another pushing of a button releases the cap the other end

ila_rendered

Onto the tools now! (god it never ends!) The wands are separated by removing the inner clip

ila_rendered

The locking button at one end slides out with the spring and retaining bit

ila_rendered

Hard floor tool now!

ila_rendered

With a mixture of torx and cross head screws

ila_rendered

It all comes apart quite nicely!

ila_rendered

The bumper slides off the top shell

The internal suction part of the head looks a tad odd though!

ila_rendered

The brush strips come out

ila_rendered

One wheel comes out, after releasing the odd internal catch for the thing

ila_rendered

The wheel itself is released from the white part by this plastic clip

ila_rendered

This white spacer tube comes out next

ila_rendered

Then the wheel comes off the other side, and the neck is released by 1 plastic clip, the same as on the powerhead earlier!

ila_rendered

Carry handle/shoulder strap now

ila_rendered

I had 2 to choose from, and chose the one with the smaller split! The shoulder strap unclips from either end of the handle

ila_rendered

And that is now apart!

Wall brushes now

ila_rendered

Compared

ila_rendered

And the better one kept and stripped!

ila_rendered

ila_rendered

I had 3 upholstery tools!

ila_rendered

Which became 1 very easily

ila_rendered

ila_rendered

Dusting Brushes

ila_rendered

ila_rendered

Radiator brushes

ila_rendered

And finally crevice tool

ila_rendered

ETC. One good kit obtained from all the duplicates. I tried to sell the duplicates. I tried to give the duplicates away but they are not uncommon to find, and many other collectors also have duplicate tools, so I binned the spares in the end!

Everything in this batch was washed and polished! The ET340 baseplate however was a sod, the blue covering would not come off after 20 years of being on, it took alot of soaking in hot water before it shifted

ila_rendered

But eventually shift it did, and we can get to this stage!

ila_rendered

ila_rendered

Don't think I've ever had a 2 part project like this!

So in reverse, le crevice tool!

ila_rendered

You position the holding piece and spring like so

ila_rendered

Then stick the external button on top, push it right down so it slips under the main tool body and push until it clicks!

ila_rendered

Got that? Good, as that will save a lot of duplication moving forward!!

 :chuckle: Radiator brush got popped onto the crevice tool so it could feel part of the proceedings...

ila_rendered

Dusting brush got its bristles clipped back in

ila_rendered

ila_rendered

And the locking button fitted

ila_rendered

ila_rendered


Upholstery tool got its groove back

ila_rendered

Wall brush got its button

ila_rendered

and brushes

ila_rendered

Carry handle now! The shoulder strap has been through the washing machine along with the bag the tools go in, and is much less cruddy now!

I fitted the strap and forgot to glue the small crack up! TBH it doesn't affect it much, it's still a massive faff to clip the cover on and I found I never really used it anyway, so it got left for now

ila_rendered

ila_rendered

Onto the hard floor head now, and the pivoting part gets popped back together

ila_rendered

ila_rendered

Plastic bush fitted

ila_rendered

Then just like that half of it is back together!

ila_rendered

You could leave it like this and just fit the brushes and it would look very cool!

ila_rendered

But you should be boring and fit the cover

Extension wand! Locking button fitted

ila_rendered

Locking ring fitted to one half

ila_rendered

Then the 2 parts slide and click together! It's much nicer to use now too, now all the grit is gone between the 2 smooth surfaces! You cant really grease this part either as it'll smear up the inner smaller half!

ila_rendered

Kobosan head! The cleaned up motor, with the bearings soaked in a few drops of oil gets dropped straight in, no messing about

ila_rendered

Then the worm drive gets fresh grease adding

ila_rendered

And the cover fitted before I put my foot in it or similar

ila_rendered

Foam roller holders clipped on

ila_rendered

And the motor is screwed down

ila_rendered

black plastic inserts are fitted to the flexible cover

It and the top cover fit on together in a bit of a faffy way, so here is the result!

ila_rendered

Then the lower part of the rear housing can clip onto that

ila_rendered

The pretty lights get clipped back into their pretty holder

ila_rendered

And fitted into the main machine

ila_rendered

The wire join was already a spade terminal affair so all I had to do was plug it back in and push the factory protective sleeve over each wire

ila_rendered

The top part was mated up to the bottom half, the pivoting rod given a slug of grease and pushed home

ila_rendered

The hidden back cover gets screwed on

ila_rendered

And the top cover clips on like a pro!

ila_rendered

The main front cover clips on now, although it did not take kindly to being removed, and most of the tiny little clips that hold it on broke, so it's quite loose now. Not the end of the world as these heads are so common still, but something to bear in mind!

With the end caps clipped down it looks alot nicer inside there!

ila_rendered

Where are we now? Oh yes, the ET340! And things start well as underneath the removeable belt cog is an open bearing, which got filled with grease!

ila_rendered

The motor gets put back together now

ila_rendered

Carbon brushes and wiring fitted

ila_rendered

Wiring tucked out of the way

ila_rendered

Brushroll drive bits fitted now!

ila_rendered

And the switch button popped onto the end

ila_rendered

Time to wire the other end of the head, and the main input wires get fed through the ferrite coil and into the holding board

ila_rendered

This gets slipped into the very tip top piece

The wires then get fed through the second neck part, and the elbow joint is re-assembled and screwed together as it's a sod to stop it falling apart as you work!

ila_rendered

Underside cover fitted

ila_rendered

The motor and drive assembly are lowered into the lower chassis now

ila_rendered

And the middle inner cover fitted

ila_rendered

Motor retaining bracket is fitted

ila_rendered

Internal hose and adapter end is fitted

ila_rendered

Wires and PCB run

ila_rendered

And the top cover can be screwed on and then the rear wheels fitted

ila_rendered

Then the brushrolls can go on

Then the EVER SO SHINEY baseplate can go on!

ila_rendered

With the front clipped down, it doesn't look half bad now!

ila_rendered

The main handle gets luzzed back together, with such highlights as fitting the internal wiring

ila_rendered

Re-wiring the top part where the mains flex comes in, and gluing up the split grommit

ila_rendered

And generally assembling it all! The washed tool bag was dry now, and looked a much darker shade of green than it did before, which was nice

ila_rendered

so I filled it with tools

ila_rendered

And finally, 400+ images later, IT IS DONE!

ila_rendered

And we had some fun! I used it for a whole month!

<a href="https://www.youtube.com/watch?v=IoGWue25tQQ" target="_blank">https://www.youtube.com/watch?v=IoGWue25tQQ</a>

I used both heads, and bought new brushes for the ET340 which utterly transformed it!

ila_rendered

<a href="https://www.youtube.com/watch?v=FV3BMXamBkA" target="_blank">https://www.youtube.com/watch?v=FV3BMXamBkA</a>

<a href="https://www.youtube.com/watch?v=K9zAex76erM" target="_blank">https://www.youtube.com/watch?v=K9zAex76erM</a>

I cleaned a computer out with it

ila_rendered

AND did a nice demo of the Kobosan dry cleaning system

<a href="https://www.youtube.com/watch?v=dBfpLQPtLM4" target="_blank">https://www.youtube.com/watch?v=dBfpLQPtLM4</a>

Which did fluff the carpet up alot, and made it softer, but was just as meh as the Dyson Zorb powder, even 3 generations of Zorb powder!

<a href="https://www.youtube.com/watch?v=lWud1onr8PE" target="_blank">https://www.youtube.com/watch?v=lWud1onr8PE</a>

But, either way I do really like it, and have kept it, as although these are still fairly common, I know this one is very good, and they usually go for more money than I paid, so I'd pay through the nose for another one!

Thanks for reading!
