Electrolux Z1910 Self Propelled - Stripdown and Refurbishment!

This very odd vacuum cleaner was given to me by my good friend Steve Cook, as he couldn't be bothered to go to the tip...
It is a basic bagless Electrolux, but with a big difference, which we shall come to later, the main issue as you can see is the lack of a bin! So in the shed it languished for utterly ages!, until a viewer of my channel who handily lived 4 miles away from my work offered me a burnt out normal model, with a bin! A short time later, this happened...
Not a valid youtube URL
and finally I could take some before pictures
It then languished a bit more, until it's time came to enter the operating theatre
Off came the bin
And all the tools

The post motor filter sits behind this afterthought looking cover
Although it's very clean, which is nice
Must have been changed as the machine itself is quite dirty. The bagless system this runs is utterly HOPELESS!
Off comes the cable
And off comes the hose and hose ends
I unbolted the handle at this juncture
Which didnt really do alot bar expose this thick cable
Time to investigate where this cable goes, and we start with the handle grip, which also contains the self drive controls

2 screws made themselves known underneath, so let's remove those
This red part fell out when the bottom was removed, which is the little red nub you see poking out of the handle that does the controlling
Lifting the top reveals this spring thing, which I worked out returns the handle to it's neutral position, the red part clips into the handle top
Clamped to the inner metal handle is the other end of the cable, which turned out to be a bowden cable that runs the whole length of the machine!
With the clamp released, the handle comes off the machine now!
We move down now. The silver top of the machine is actually a big clip on cover
The tool holder can be removed now
Look, a date! 1997
With that removed, the big suction inlet to the bin can be removed, this forms the cyclone top and look at the efficiency of that! Shark would be proud...

The business end of the contraption has a massive rubber sheet stuck to it, which acts as the seal for the bin
Crikey
With that bit removed, the lower part of the metal handle falls out, being held in by the just removed part
The bowden cable loops out and back in to this part of the handle
I then discovered why the self drive mechanism never worked very well....
We'll worry about that later
Because on the other side of the top to the tool holder is the MASSIVE switch assembly, with one screw just begging to be removed
Here we see the mains cable and internal cable together in sweet harmony around a broken screw standoff...
Simple affair with a switched live here
The switch just pops out, revealing the tantalising cutout for variable power, probably fitted to the TOL American Eureka version that used the same chassis

With all that rubbish out of the way, the 2 cables simply fall out of their places to go
And we can flip it round and have a look at it's undercrackers
Then swiftly flip it back over as on these models the hood screws on from the top
Like so
handy belt change instructions printed here
Some bum fluff build up was noticed
The only thing to need to be removed from the hood is the belt guard
The brushroll just lifts out
and comes apart nicely. Even the bearings could be replaced easily, although in this care that is not needed as their lovely!

Under this cover, the magic lays
A thumping huge motor!
and the other end of the bowden cable
I unclipped that
Then started finding wires. These went to a switch. Not a brushroll switch, but the switch to turn the self drive motor off
Turns out they were also the main feed to the motor itself so 2 clamps later and the whole thing split apart nicely!
Now I can get to the screw holding the switch in place
and remove it
Next, the 2 screws as indicated hold the drive motor in place

The motor and the utterly compacted pile of fluff kicked up by the driven wheel (yes, thats right, the ONE driven wheel) over the years! It was quite impressive actually
This bit of foam covers up the area around the lever the bowden cable moves, it's doing a sterling job of keeping all the fluff out...
more screws later and the wheel assembly itself can be removed
And we can see how the whole thing works
What happens is, the machine can be propelled forwards and backwards, the handle pulls or pushes the bowden cable, which in turn pushes the lever on the motor left or right. The whole back end of the motor moves with the lever, and contacts either the left or right side of this contraption of gears and bearings! one side makes it go forwards, the other side back! The whole ling lifts out of the shell
And starting from one side, the first set of shims and the most dinky shallow bearing I have ever seen come off
Then, a circlip, washer and locating block come off

The next hurdle was this metal pin, which was knocked out
And the next stage can come out
In the middle sits this bracket
and the other side is an exact mirror, which once part looks like this
Behind each of the metal bits that hold the locating pin, sits the plastic cog, which has a layer of cork type material on the back of it. When the lever is pushed to the side, it pushes this drive cog against the metal part, causing the drive to be transferred to that side. Neutral is in the middle not touching either side! very clever
But then it gets even more old school, the levering motion is controlled by this cage here, the bowden cable connects to it
And depending on its pivot it actually pushes the whole appropriate side of the cog assembly against the drive wheel from the motor itself. It's lovely to see such actual engineering on a vacuum!
The drive motor is screwed onto the cage holding part
Which reveals that the drive passes through an adapter shank from the back of the motor, it's no wonder this thing weighs a frigging ton!
Said adapter shank is held in with a circlip
And the whole thing nicely comes apart

I inquisitively popped the cover off the back of the motor, and made a note to fill it with grease later
Onto more mundane affairs, the spring that sorts the height adjuster out!
Once removed the wheels pull all the way vertical then pull out
And then delightfully strip down even more!
I pulled my knob out
And moved on to the release pedal, 2 dodgy looking tabs here
Which came out without drama
Furniture guard removed
With all that done, we can remove the motor cover and oh my gosh

First out is the utterly knackered pre motor filter and the metal shelf that holds them in
The motor itself seems to be inside a nice case
The suction inlet pops off
oooh 1998 this time
It too has a more complicated than it needs to be seal assembly
We can get the bowden cable out now, which is indeed quite broken
Put that to one side for now
This pathetic excuse for something I think packs the void between the bowden cable and chassis out, as the outside of the bowden cable cant move so the inner wire does, hence why its no good with a sodding big broken bit
We can lift the motor out of its dusty hole now

There's lots of stuff wrapped up in this foam
Unwrapping it took ages
And this is what lurks beneath
The wires look easy to remove, so lets get those out
then see how this plastic shell comes off
The white rubber grommit comes out
As does this random plastic tube which goes nowhere and controls nothing

Then 2 long screws come out
and the cover lifts off
another foam seal
Even the 2 terminals have little foam seals!
foam seals with plastic housings! This is very bizarre and overkill!
A more normal looking fancase seal comes off
top seal
Naturally, the super efficient filtration had filled the fan up with crap, so off came the fancase
and off came the fan

Next we needed to unscrew and remove the top housing. gently, gently...
Still, the wobble washer came out nicely
Coil lifted out
MMMM crusty
Next, I gently tapped the top of the armature to pop it out of the fancase rear. Which went well until this happened...
Rusted on so badly that this part snapped, and I buggared the threads up on the armature as I forgot to fit the nut before hitting it... Grrrrrrr, moving on swiftly
This hose needs to come off, surely I cant break this bit?
One screw
Ah no its alright, it comes off nicely!
Upper and lower cord hooks removed

Onto the bin now!
It has a filter on it, so we remove that
The handle/securing clip unscrews
then 2 screws on the back release the :biglaugh:cyclone
The dirt that didn't come out despite a good bashing over the bin can be seen here
And that's that stripped. It all got washed and forgotten about in the airing cupboard for a week, whilst I sorted the motor. I did have a spare motor, sort of... From the machine that donated the bin
Not a valid youtube URL
So I smashed the motor out of it and bought it home
The top bracket came off with no bother at all, so one thing ticked off. The armature however, was touch and go
The carbons on that motor were knackered
However the carbons on the original now broken motor are in good order

Not daring to try and remove the random permanent washer thing on the new/old motor, I skooshed loads of spray oil over the bottom bearing
properly did the top bearing
Fitted the washed fan from the now broken motor
and hoped it ran, the comm cleaned up not too bad, but there's not really any way of telling until this
all goes back together! Which will be for another night, as it's bed time now! Bye
