Earlier in the year, I get mentioned in a facebook comment. Something about a ratty old vacuum coming my way for a refurb. Whatever, nae bother!

Via Dilys at Autovac, I recieved a parcel back in August!

It was a wonderful beast

ila_rendered

Very Orange



Looked very at home by my parent's 1970's fireplace, on their 1970's carpet!



But it needed to be moar orange, so home it came, looking very out of place on our modern carpet!



First things first, remove the cable

ila_rendered

Then remove the bag

ila_rendered

The top handle screw incorporates the later style top cord hook, so removing the nut allows the whole thing to drop off

ila_rendered

The holder can be removed from the cable guide

ila_rendered

The handle nut sits in a groove to stop it turning when assembling

And the top handle can come off!

ila_rendered

Apart from a tiny chip in the cord hook, it was in very good condition, no work needed here bar a clean and polish!

ila_rendered

The bottom handle part was slightly more worn when it came off, decades of not being tight enough probably

ila_rendered

Packed out by this ancient bit of card

ila_rendered

Next, the carry handle cover needs to be removed

ila_rendered

Revealing a cable join

ila_rendered

Which handily slides right out

ila_rendered

Mains cable clamp is removed first

ila_rendered

Then everything else is undone/falls out to leave an empty shell. One of the captive nuts fell out, I removed the other one so it didn't get lost

Judging by the crimped cable ends, it's the original cable too

ila_rendered

With the cable removed, the top guide can slide off

ila_rendered

Now, it's time to turn her over

ila_rendered

And remove the base plate, which is screwed on rather than the thumb latches of old, although the latch mouldings are present on the lower chassis

ila_rendered

ila_rendered

The very worn soleplate seal was carefully removed flr cleaning and plumping up

ila_rendered

Out came the brushroll, which had fantastic brush strips

ila_rendered

Some fluff under the non removable furniture guard



Now for some more electronics, which sit under this cover

This is the 2 speed switch, for changing the motor speed to a higher setting for use with tools

ila_rendered

Tis a lovely thing

ila_rendered

The green cover hides more wires

ila_rendered

Also holds the ratings plate

ila_rendered

June 1978

The rear of the 2 speed switch housing lifts off the machine with the switch and wires removed

ila_rendered

Under the green cover sits the on/off switch, which is removed with 2 screws

ila_rendered

The switch cover lifts off the switch

ila_rendered

Now, we can remove the tool adapter tray with 4 screws

ila_rendered

It was a bit grubby

This plastic flap seals the suction when the tools are not inserted, and is pushed up with the tools adapter

ila_rendered

It has a rod and spring through the middle, this gets gummed up with fluff and jams up

ila_rendered

Next, we can remove the rear wheels, since the adapter plate holds these down

ila_rendered

The axle is connected to the adjustment lever with this bracket here

ila_rendered

1 circlip needs removing, the wheel taking off and a metal bush slid off and the whole thing slides out and off the machine

ila_rendered

The bracket is held with another circlip higher up, we'll get to that later

ila_rendered

For now we can remove the 2 top hood screws! And reveal a lovely tidemark

ila_rendered

We can get at the bracket now, remove this circlip

ila_rendered

And it's free! Note the swarf coming off the screw threads too as their removed! The main thread is the metal caps on the end of each standoff, but the screws must cut a little thread as they went in in the early 1970's

The height adjustment lever slides off now

ila_rendered

Another circlip keeps a very thin metal cable bracket in check

ila_rendered

ila_rendered

On the other side of the machine we have the handle recline pedal

ila_rendered

The bracket is unscrewed, and the spring retrieved from the other side of the room

ila_rendered

This stepped piece forms the pivoting mechanism

ila_rendered

This being the pivot bar

ila_rendered

Then the whole pedal assembly slides off the end, being unhooked from various pivot brackets along the way

ila_rendered

With ALL that removed, the main bar that holds the handle fork on can be tapped out

Which brought with it the white bag latch, which should slide, but at the moment does not too well

ila_rendered

The broken bulb was removed

ila_rendered

Could be vintage, could be very modern, the GE logo hasn't changed!

ila_rendered

Getting there

ila_rendered

The main reason for popping the bulb out was to flip it back over without smashing the bulb into the carpet, and remove the front wheels

ila_rendered

They simply slide out after removing the circlip

ila_rendered

Back the right way up, we'd better remove the time bomb

ila_rendered

Bracket removed, screws replaced so I know where they go when this is not refitted!

ila_rendered

We can now remove the main wiring loom

The black wires go to the RF supressor, the yellow and white wander off to the switch and motor

ila_rendered

ila_rendered

It all lifts out when removed

ila_rendered

Next, the screws holding the motor to the chassis can be removed

ila_rendered

And the motor lifted out, revealing some hidden dirt

ila_rendered

The compacted dust crumbled nicely, good to know this hasn't been damp

ila_rendered

The chassis is now naked!

ila_rendered

This metal shield plate lifts off the main motor

ila_rendered

Revealing it to be a bog standard Senior 652 motor

The seal pulls out

ila_rendered

Belt spindle and fan off

ila_rendered

And the spacer washers

ila_rendered

Carbons next, and the genuine ones have decades of life left!

ila_rendered

The top bearing can be removed now

ila_rendered

ila_rendered

The cooling fan spun off the shaft

ila_rendered

The top cover removed

ila_rendered

The field coil is bolted down, so they were removed

And lifted out

ila_rendered

Empty!

ila_rendered

Armature looks in fine order

ila_rendered

Just the bag left now, and I'm presuming this is the original fixing method, penny pinching removed the metal band and bolt and replaced it with a cable tie! Either way, snip

ila_rendered

Probably hasn't been off in a while, or ever

ila_rendered

Lovely



Bag fill tube next

ila_rendered

Genuine bellows

ila_rendered

Split

And lastly, the brushroll was stripped

ila_rendered

The knackered bearings flung hard into the bin

ila_rendered

A big pile of washing up was waiting for me

ila_rendered

Which was done, and whilst it dried I cleaned the gunk off the coil with a baby wipe or 7

ila_rendered

Cleaned the wiring up

ila_rendered

And stripped the plug down

ila_rendered

Then, a bowl of warm but not hot water, and some washing machine liquid was thrown together

ila_rendered

And the bag was thrown in, swooshed about a bit then left to sit for an hour or so

ila_rendered

Another good swoosh about produced this, which isn't terrible by any means

ila_rendered

It bought the vinyl back though, it went rubbery again, and smelt lovely, not of dust!



I hung it up to dry, as it was lovely and warm back in August, not 8" of snow as we have had today!

ila_rendered

Then, I made a start on the metalwork. The brushroll axle came up nicely

ila_rendered

I buzzed the rust off the motor shield, rather than polish it up

ila_rendered

Brushroll end caps before



Brushroll end caps, wheel axle and brushroll after. The brushroll has been stripped

ila_rendered

And then I painted it with Euro Car Parts finest hi build primer and Poundland's finest black paint, which came out alright! I'm rubbish at painting whole machines, but getting good at brushrolls!

ila_rendered

I also had a brainwave, and masked off the beater bars, so they stayed nice and polished

Next, I got my finest dirty rag out, and a good blob of spit and gave the plastics a good rub down...

ila_rendered

ila_rendered

ila_rendered

ila_rendered

ila_rendered

Which made it come up rather nicely! Time for the bit I love the most, EXPLODED SHOTS!

ila_rendered

ila_rendered

ila_rendered

Then, time to put the brushroll back together

Brush strips slid very carefully in so I didn't chip the paint

Nipped up



Next, a Genuine Sebo Bag (couldn't go sending a pattern Sebo bag up to a sebo dealership now could I...) was procured from the shed of broken dreams



It's head was chopped off

ila_rendered

And it was fitted to the bag fill tube, giving the machine an instant massive filtration upgrade!

ila_rendered

The bag assembly can be thrown on the the 'done' pile

ila_rendered

Motor now

ila_rendered

Yes the bearing went through the wash, and yes it is fine with it! Just needs a little lubrication now, which it needed before tbh

ila_rendered

The coil was bolted down

ila_rendered

Armature dropped in
