Hoover Junior U1346 (December 1969) - Restoration

Hello my Vacuum Cleaner Chums!
A few days ago, I got 2 parcels from our good hosts
//www.youtube.com/watch?v=TD2nqi3UlQo
There was some modern rubbish in there, as well as 2 Hoover Juniors. In this thread, we will concentrate on the Brown 1969 Junior. Apparently the last in the line, a Phase 3, soon superseded by the 1346A (as helpfully explained in the comments on the above video!
The ratings plate is present, but just about readable
The immediate issue I saw was the lovely original rare as
bag had paint all over it
The rest of the machine wasn't too bad though
It won't be too far from home in the Dyson Museum either, having seen action 13 miles away at some point in its life
The bumper was hanging off at the back
And there is a big crack in the side

The belt pulley, a common wear point, was lovely and unworn
The same could not be said for the belt
Let's get the bag off, it's held on with a screw and thread
and it lifts off the collar
There was a bojack bag fitted
Which looks quite old judging by the other machines listed as fitment
With the bolt removed from the lower collar, the bag peels away from the bag fill tube
Which by the looks of it, hasn't happened for a while!
The bag holder (a rubber belt) is removed
and the bellows seperated from the bag fill tube

Initially, the bag fill tube looked blocked
but it turned out to be a piece of foam stuck to the inside, presumably to stop the noise of grit bouncing it's way to the bag
After a damn good bash out it looked much better
Top half of the handle now
The bag support bracket is held in with a circlip and bar
With the circlip removed, and the bar withdrawn the bracket falls out the handle
The cable is held up at the middle by a
and bracket
The bracket pulls off the
The bottom part of the handle is bolted to the handle bail assembly, at the bottom (if you hadn't already guessed!)

The lower handle section fits into the handle bail by means of a rubber housing, which pulls off the lower handle part
The machine is MUCH easier to photograph now...
Belt guard off
Holding bracket removed
Next off is the release pedal to lower the handle, as the handle assembly won't pull out with it fitted
Out comes the brushroll, looking a bit peaky
The belt looks very past it now it's fully out.. Still span the brushroll though, I'd like to see a DC07 do that with a belt in this state...
To strip the brushroll, first unscrew and end cap (one side will come off, one side wont)
One side had an end cap spring fitted, which was nearly falling apart
Grip the brushroll axle with something, and unscrew the other end cap. Both should now be free

Here we encounter the first issue. One brushroll bearing came out of the end cap fine, the other not so fine
The bearing had seized, then violently unseized itself at some point by shearing the 2 halves apart, so the inner part, stuck fast to the end cap needs some tappy action with a small/medium hammer
Brushroll strips (which are of superb length and stiffness) are slid out
And that's the brushroll done!
Next, we remove the lower cover from underneath the machine
As with all Juniors of this age, the spark arrestor pad is perished to dust, so I removed the remnants, I doubt it sparks much anyway
Which is just as well really, as sparks would have loved this...
I dug a bit, and found a motor!
First, I removed the cable
Which allowed me to pull it free of the various
s

Looking at the cable, it has the original wiring terminals on, but they looked very frayed and horrible
So I chopped them off
Next, we remove the rear wheels
By removing various circlips and washers, they strip off their axle
The other 2 screws release the handle bail assembly, which withdraws easily due to us removing the release pedal earlier!
This is where they wear, this step wears smooth, and the machine no longer sits upright. This one isn't too bad, if you jiggle it about it flops down, but picking it up squarely, and pushing it on it's wheels is fine. It would certainly be alot of work for not much gain to re-profile it, so I left it!
Next out of it's fluffy home is the front wheels

Of course, a whole fake mustache was hiding under it
More circlips and washers later
Next off is the furniture guard, which had been stuck on at one point in it's 47 year life, and removing it took some bits of plastic with it...
Getting there!
But first the switch needs to be removed
Next, to remove the motor, and this is where a very long screwdriver comes in handy
out she comes!
In these next few pictures, I tried to point out what wire went where, but failed miserably as I got them wrong, so:
This terminal (the top carbon brush) has a black wire, which goes to one side of the supressor

As shown in this picture...
With the screw removed, the bracket holding the carbon brush spring is removed
But not the carbon brush itself, as it's stuck in with fluff... (the spring came off). So next off, is the black cable from the other side of the supressor, which goes round and joins up with the neutral cable from the mains
The wire left in the terminal block comes from the switch
which once removed releases the switch a bit more
The switch cap pulls off the switch itself
The live wire from the switch plugs into one side of the supressor. The black wire (unrelated but runs through the conduit) is the neutral from the terminal block to the supressor. Both pull out of the supressor
The long red wire comes from the field coil, and the short black is the one that sits on the top carbon holder
Next off is the supressor, which also holds the field coil on inside

British Made
I'm not too sure what this is, but I'm going to say an earthing strap. These machines are double insulated, so no need for an earth wire (stuart...) (where's Tech12 to confirm? He would know!). It joins the rear bearing housing to the supressor bracket
The bottom carbon holder was buried under some more fluff
Now we can crack the motor open. There are 4 screws and bolts, 3 are black, and are fancase side, and one at the rear
And one is shiney, and also forms the bolt that holds the rear bearing bracket in place
Lol
The motor housing seal comes off now, and is in great condition, so no need for silicone sealent replacement
This machine has seen alot of fine dust in it's time, the front of the motor casing was packed with it!
When the motor housing was opened, the terminal block fell out, as it is just held by 2 tabs, locked into place when the housing is screwed up

Now we can see the other carbon brush holder, hidden away under the motor cover
And the fancase bearing
The rear bearing is half released already, one more screw removes the bracket fully, and the armature can be withdrawn
The rear bearing is in very good order
Bit dirty, but spins beautifully
Time to look at the armature now
Holding the armature in one hand, hold the fan and turn it anti clockwise, which should release the belt pulley, then spin it off, and remove the pulley, fan, fibre washer, 2 spacer washers and standoff tube
More plaster dust under the fan (I'm not sure if it's asbestos or not, but I didn't lick it so I should be ok...)

The fan is original, which is nice to see, and in great condition
The trusty bearing puller released the fancase bearing
Which was utterly filthy
But cleaned up well, and again, is smooth as silk. It's seen new bearings before!
With the little yellow wire unscrewed, the field coil lifts off the motor housing (well, it would have come with the armature, but lets not split hairs)
Nearly there!
I can now push the stuck carbon out with a small screwdriver, and they are quite worn, probably only another 7-8 years left in them...
The carbon brush holders unscrew and lift out
Now the motor is stripped into it's component form, time to move back to the chassis
3 screws help hold the firewall to the chassis

With them removed, it's time to break the seal, carefully prise around the join until the ancient glue stuff gives in
and the firewall and air path can be lifted out
Here we can see the other side of the large crack
And some damage done by the rear bumper/impact damage
and some fine cracks on one side of the brushroll end
None of which were too bad, and the whole thing was still sturdy, so I opted to dribble a tiny amount of glue into them from the inside, and leave them alone!
The belt guard underneath is removed by releasing the spring, and the rest falls out!
Empty!
Full!
Everything was soaked overnight, then washed, cleaned further with cream cleaner, then I cracked the machine polisher out...

It came up bloody beautifully
Ogling over, I cleaned the firewall off
and turned to our mate Tommy for some help
to re-seal everything up!
And a large, thick bead around where the firewall goes

And fitted and tidied up
As tidy as it can be the other side, where my fingers wont reach
One thing we have not touched yet is the handle bail assembly
On this side, a tiny circlip holds it all together, which releases the metal guide, and metal plate (which pushes the mechanism down when the release pedal is pressed)
The 'bolt' (which isn't really a bolt) pushes through now
Which releases the 2 main halves, along with the tensioning spring
The other 'bolt' (with the recessed head that guides the release plate) is held in with another circlip, and when pushed through releases the spring plate.
Like so! The whole lot was cleaned off, and given a buff with wire wool to make it shine, then back together with some lovely new grease
