Hoover Junior U1346 (December 1969) - Restoration

[beko1987]

The spring sits snugly inside the lower half



and slides into the top half, with the 'bolt' pushed through before it all moves about!



Release plate fitted



To tension the inner spring, you simply pull the end of it across and over the tab inside (I didn't take a picture, but it's easy when it's infront of you)!

Done, a quick wipe over to remove any greasy prints from assembly



All the other bits were ciffed up



And we can start on the motor



Following a very helpful guide on Vacuumland, which says 'Oil your sleeves and Grease your balls', I got some spray grease, which is a bit like oil...



and saturated the felt oil pads of the motor bearings with it!

Carbon brush holders back in



The coil (be sure to have the side with the mounting holes for the supressor facing the holes in the motor casing) slides over the armature, and with the bearings fitted either end slots into the motor housing. I then did the rear bearign clamp up (and fitted the earth strap)

[beko1987]

Rear bearing clamp screwed down the other side



To stop the whole lot flopping about, I fitted the clamp to the supressor, and screwed it on, which screws up the coil as well



I forgot which way I disassembled it, so quickly put the fan on whilst it was accessible







Fancase bearing clamp fitted



We need to get the terminal block ready now



and one final check of the internals, before we get the carbon brushes



I scrapped a 1334 for parts a while ago, and found it's tub of bits, which has much better carbons in, so pinched those for this



We need to fit the lower one now, and fit the yellow wire and screw it all up

[beko1987]

With that fitted, the casing can be done up nice and tight



Let's put the cleaned up wiring back in now, as it came off! Which is:

Black wire from terminal, around the motor and into the back of the supressor
Black wire the other side of the supressor up into the top carbon brush housing
Red wire from terminal into the switch
Red wire back out of the switch and into the back of the supressor
Red wire from the other side of the supressor, around the motor and into the coil (hard wired).



Motor to chassis seal fitted, and I put a smear of grease around it to help the seal



and filled a hole (the light was fading by this point, so the picture quality takes a drop, sorry!)





Screwed the switch up as it was getting in the way flopping about



Whilst admiring the hood on the table earlier with a few beers, I got the 0000 wire wool and Silvo out, and polished up the axles, so we can now put the front wheels back together



and fit them to the machine



Then drop the handle bail into the chassis, and screw the rear wheels on

[beko1987]

I fitted the bumper



put the belt cover back together



and called it a night!

The next day, I got the cable fitted



Push it through the handle , lower handle securing and cable entry , then strip the wires




I stripped enough off to make a loop at the end, and screwed them down neatly



and fitted the cable clamp



Cover back on, and we are done under here!



Tuck the first into its slot



Fit the rubber sleeve to the bottom of the handle

[beko1987]

and fit the lower handle, the cable to the securing bracket, slide the securing bracket onto the upper handle, fit the upper handle, move the bracket to over the holes and bolt the whole lot together!



Bag fill tube and bellows now



and using some fairly crap double sided tape fit the foam stuff to the inside of the bag fill tube



Then fit the tube and bellows together



Now for a hack! Take a Miele S7 bag



Chop the top off



and with some considerable difficulty (would be easier to just cable tie it on than try and manouvre the bag holding belt tbh) fit the bag to the fill tube



Voila, HEPA bollocks, but most importantly, no more dust leakage through single wall bags, messing up our nice, washed, clean outer bag!



I find it easier to fit the bellows to the machine first



Then the bag around that. As an added bonus, the paint DID almost come off, a few tiny spots are left, but any more work would have risked ruining the bag.

[beko1987]

At this juncture, Amy went shopping, with something on the list for me. So I made a silly video comparing a refurbished machine against an unrefurbished one (both sans brushroll)

The result annoyed me tbh, but the 1346 sounds beautiful!





Amy came back from town



Which was good, as when washing it, all the paint flaked off the brushroll! So I cleaned it up with some sandpaper and wire wool...



and over the afternoon gave it 7 coats of this!

which made it look jolly nice



Time for some shiney new agitator bearings



the wobble washers cleaned up



Brush strips in



End caps in

[beko1987]

Assemble one end of the axle as shown (mind which side is which, as one end is keyed, one isn't!



Then build the other side up



Take a nice new belt from the special spares box you keep in the shed



A genuine Hoover spare



Fit nice new brushroll springs either side





and fit the brushroll



Fit the belt



Fit the belt cover, which is sporting a lovely new Hoover Roundel (not quite the right size sadly, but beggars cant be choosers with unobtanium stuff!)



And there we are! One Hoover Junior, working as it should.

Eva filmed me demonstrating it once done!

I've been typing for nearly 3 hours now, I'm off to bed, night!

Good lord, that was a marathon thread! Great job!

I imagine MVacs will be pleased.

This will really help me actually, I've got a practically identical 120 volt junior that needs this treatment.
Do you by chance know any way to help a brush bar for one of these that vibrates a bit too much?

[beko1987]

Id start with bearings and belt first,  if its not that then the brushroll could be off balance maybe? Find another to try?

[MVacs]

What a bloody magic job by the motor whisperer! 

And what a cracking thread, photos and videos! I'll be more than chuffed when this lands back at our place for the museum. It might even get a glass case. 

[beko1987]

She deserves it! Just take the belt off after you've all had a good play so it doesnt strech in storage!

Or, thinking about it now I've had alot of coffee, the brushroll could be full of dust, which causes an imbalance when spun

I'd have it all apart, clean it all, then fit a new belt and try, then new bearings, then maybe check that the belt spindle isn't wobbling around (you should be able to see it with no belt fitted

[dysondc16]

Thanks Sam, I've had it apart before to clean it out and lube the bearings. I'll see about replacements, and I'll check the belt spindle later today. The junior was not very popular over here, and parts are not very easy to come by. I just might have an extra brushroll somewhere.

Can't wait to see the lone hoover in the midst of all those dysons!

[beko1987]

If you narrow it down,  im sure parts could be shipped over! It must be bloody rare over there! What model number is it?

[Vacuum Cleaner House]

Hey Sam
It looks awesome, I used to have a special grease gun for those bearings
This here is a 652 I restored a 4 years back. It was in terrible condition when I got it but looks like new now.
