Hoover Senior 612 - Stripdown, Restoration & Refurbishment

I think this was a job for Our Mvacs, but either way, tonight's topic is about this lovely Hoover 612, with non original but genuine replacement bag!
It had a working lightbulb in
Although underneath was not too pretty...
Serial Numbers running from J.672400 started in January 1955, then the next batch of J.718880 started in July 1955, so March-ish 1955 she was made I'd imagine.
And some initial damage, although not too bad really

Let's get started, looks a bit sorry for itself
The paintwork is not too bad
Here is everything for the handle
Time to remove the bag first
Looks lovely
Top clamp holder off
Then I removed the bag from the bag flange
Onto the machine now. Belt guard off
Brushroll and belt removed

Unscrew at both end caps until one turns, and remove that one
Then hit with a hammer to extract the spindle
Remove the other end cap and bearing and wobble washer from the axle, then remove the screws and brush strips from the brushroll barrel
Next, underneath the vacuum, undo the 2 hood screws
Then carefully flip over and remove the hood
Hood retaining brackets removed
The brass decorative strip unscrews from the top of the lens cutout in the hood
Then the Hoover letters were removed
With the hood now stripped, it's time to move on

The first thing is to remove the cable from the handle bail. 2 connections here
Then this guide thing is also a clamp, remove the screw
And pull it out
The handle bail spring can be removed from the machine too
Next, undo the nut and remove the handle bail bolt and washer
This inner spring is welded to the bail and can't be removed
Onto wiring now. This machine is original as far as wiring goes so it should work for other 612's. The red wire runs from the lower terminal on the bulb holder, around through a wire tidy and to the switch
The other red wire comes off the switch and to the live terminal for the mains flex

Things escalate quickly as we can remove the wiring terminal AND motor completely now
Motor housing-Chassis gasket peeled off
The neutral wire runs from the main cable to one carbon brush terminal. Then another wire goes from the terminal to the top bulb holder terminal
We can remove the neutral wire from the terminal block
Then the wires/carbon brush
Then bulb holder.
The next thing to be removed is the 1950's (more likely 1940's in design and manufacture...) RF supressor...

With that out of the way, the yellow live wire to the coil can come off the lower bulb holder terminal, then we can undo the smoll screw holding the bulb holder to the motor housing
Remove both carbons
Then, at the top of the motor, remove the 3 remaining top bearing screws (the 4th came off with the supressor ground wire)
By holding the suction fan and twisting, the top cooling fan will untwist from the armature
Layer 1 is done. Now remove the 4 screws holding the rest of the motor housing together
I leave the carbon holders in when washing the housing, their always fine.
The coil comes out now, remove the nuts and bolts holding it on

Next, hold the armature with one hand and twist the fan with the other in the opposite direction. The belt spindle should start to loosen. If not, some vice grips on the belt spindle help, but you need to undo the belt spindle, then remove the fan, then the red fibre washer, all the tiny spacer washers behind it, then the spacer block. The armature comes out of the front bearing now
It's grim, but the bearing is riveted in place, and will clean up OK yet
Now the motor is out of the way, on the chassis we can see the little screw holding the handle release pedal in place
With a small circlip the other end
It can all be removed
Next, remove the 2 screws holding the switch into place
The pedal comes away first
And the pedal unscrews from the arm even still
I leave the centre pivot part alone though

We have one more screw holding the wiring harness in and the switch can come out
On the switch itself is a rubber boot
Then the shallow nuts can be undone and the switch removed from the holder
Next, we need to remove the back wheels. Some downwards pressure is needed to push the springs down whilst the retaining pins are removed
Their not under masses of tension though
The rear wheels are held on with a circlip each
The springs needed to be peeled off the filth on this bit!

Next, we remove the front wheels
A circlip each and they slide off the axle
Then the axle unscrews from the chassis
The next thing to come off is the tool port
Which splits down more with the removal of the retaining bar.
The belt guard spring comes off next, which then releases the cover plate
The bumper stayed on for this restoration. Firstly I had not found my new way of re-attaching them, B it didn't really need to come off anyway

The bag took several washes before it stopped doing this
But eventually everything was washed, polished, all the metal parts were cleaned up on the wire wheel and it was ready for re-assembly
The original paintwork washed then polished then waxed up really well
Bit of Patina here and there but otherwise all good
I even re-painted the heads of the originally painted screws...
And we start with the tool port, which I had to paint as it was just too corroded
Flap re-assembled (this is pushed out of the way when the tool adapter is inserted, then the adapter wraps around the fan diverting the 'suction')
It can then be fitted to the machine

Wheel axles back in, with a little bit of grease to stop the wheels squeaking
Wheels back on
Rear wheels next
The housing survived under the dirt quite well
Wheels refitted
Then it's time to sit the springs onto the chassis
Then carefully and evenly press down until the holes line up and fit the retaining bars
Switch time now! Refit the switch to the holder and put the rubber cap back on

Then slide the outer sheathing back on to the switch wires
Switch arm back together
Then it can be refitted, clamping the cable out of the way of the wheel
Next, refit the recline pedal and bracket (guess what I had to take out not long before taking this photo...)
Then we can rebuild the motor. Start with the fancase bearing
The 2 nuts and bolts
And refit the coil
Refit the armature. Fat spacer, thin washers then red fibre washer go on the other side

Then remove all those washers as I forgot to tell you to flood the bearing with oil, you should be able to spin it by hand and feel it free up, it should free spin for ages. Then refit the washers and then the fan and belt spindle
Up top, fit the upper motor housing cover, then screw the cooling fan back on
Then a small smear of grease on the top of the armature and refit the top bearing (it's a dry sleeve bearing, but a drop of grease takes up any imperfections present after nearly 70 years
Fit one of the yellow coil wires to the nearest carbon brush holder, with a carbon brush underneath it
I then tend to stick the motor down to the chassis with a smart bead of silicone (I usually use clear, but I only had white at this time). The original seal is always dry and awful, this ensures a fully airtight seal and usually makes a big difference
We can then wire the other yellow wire to the bulb holder, then run the switch wires where they need to go, as well and the neutral.
The RF supressor is the type that just goes into the existing circuit, rather than having the circuit built around it as they later did, so it's a nice easy job

I gave the Hoover letters and trim a good polish with autosol
We can then refit the handle bail and bolt it in, then run the (new) flex through the handle bail and screw it all up
We were missing the original cable clamp, so I improvised with zip ties
This spring is great fun to refit...
Onto the brushroll now, all freshly painted, the brush strips can be refitted
Then the re greased bearings and end stuff refitted to make a brand new brushroll!
Fitted with a new belt
Then covered back up

Now we can place the machine on it's wheels I feel safer fitting the hood
One final check and fit the bulb back
And that looks lovely!
I fitted the nice age appropriate MK back to the new flex
Getting there
The replacement bag had a sort of fill tube in it, so I extended it with zip ties and an old junior fill tube, and fitted an inner Sebo bag
And with that, the restoration was complete
A nice refurb on a good daily driver!
