Hoover Junior 1346A - Stripdown and Refurbishment!
« on: June 25, 2019, 11:48:34 PM »
A good while ago now, this came my way for free! A great chap up in Scotland sent it to me as 'you like these, don't you?". Which was amazing really!

This is what it sounded and looked like when it arrived


Not too bad, the usual neglect, but actually very little damage! It ran really well too



Soon, it became it's time for a good old fashioned wipe over with a dirty rag



First off, is the belt cover

ila_rendered

Revealing it's credentials

ila_rendered

Being this close we can see lots of paint, but no actual damage. Hmmm

ila_rendered

Moving on up to take the bag off, the cable looks lovely, in a 'might kill you if you lick it' kind of way



I unhooked the bag from the top

ila_rendered

Which was a silly thing to do as it makes it trickier to get at the retaining bolt, so back up it goes and ah! there we are

ila_rendered

Off you come!

Inside, we have an dust bag

ila_rendered

The retaining bolt is removed fully and the circlip replaced (the circlip stops it coming right out when loosened to remove the bag, bloody rare to see one fitted nowadays as they usually fall off anyway with enough force turning the bolt)

ila_rendered

The bag is in MINT but filthy condition

ila_rendered

ila_rendered

Cop a load of this retro Eeze-Fix bojack bag!  It's been re-used a few times by the feel of it!



The bag fill tube can be removed from the bellows, and initially it looks blocked

ila_rendered

But it's actually the foam sound deadening that stops the noise of the grit bouncing up and into the bag

ila_rendered

Both the foam and the bag went into the wash

ila_rendered

The foam didn't take much cleaning as it doesn't really hold the dirt, so it came out after a good swoosh about and...

ila_rendered

(more later! One of the children has just woken up...)

It came up rather well

ila_rendered

ila_rendered

Let's get this nice plug off the cable

ila_rendered

ila_rendered

It's been tugged at some point or another

ila_rendered

Middle handle bolt out

ila_rendered

And the top handle off

ila_rendered

Remove the circlip holding the bag holder bolt in

ila_rendered

And the rod can be removed, and the holder and spring slid out the bottom

Cord clamp and boot can be slid off the cable now

ila_rendered

Lower handle bolt out

ila_rendered

And the rubber boot removed from the handle

ila_rendered

Belt cover now, inside is very clean

ila_rendered

Latch unscrewed

ila_rendered

The Hoover roundel was half off as well so I removed that too

ila_rendered

Onto the exciting bit now

ila_rendered

The release pedal was unscrewed

ila_rendered

And the rubber grip slid off

Time to roll her over and give her a little tickle to reveal the underside... :underchair:



And remove the bottom cover

ila_rendered

Which reveals a very clean motor area, seen ALOT worse (Stuart's brown 1346 springs to mind)

ila_rendered

As usual, the spark arrester pad had turned to dust, so it was removed

ila_rendered



Time to remove the cable now Clamp removed

ila_rendered

Terminals removed and oh look, this might be the original cable!

ila_rendered

Lower cord guide removed from the cable

ila_rendered

Time for the rear wheels to come off. The 2 rear screws do this

And off they come

ila_rendered

And apart they split

ila_rendered

The two other screws release the handle bail

ila_rendered

Which lifts out

ila_rendered

And with a tap of the magic hammer

ila_rendered

is apart! Front wheels now and ah look, an bodge!

ila_rendered

Seemed a very good bodge though, doing its job well

ila_rendered

I love peeling these back, their always full of crap behind!

ila_rendered

And apart the font axle comes too!

Time to extract the switch now

ila_rendered

ila_rendered

Then, remove the 4 screws holding the motor in and voila!

ila_rendered

The brushroll can come out too

ila_rendered

And come apart. One side off

ila_rendered

Crikey, full of greasy crap

ila_rendered

The other side can be pulled out now

ila_rendered

And with the rod gripped, the other end plate can be unscrewed

ila_rendered

One bearing side apart, the plastic spacer washer was paper thin (I never get on well with replacing them though, brand new ones cause the roller to bind up, must look into that one day)

Now time for the other side and ah bo >:( >:(ocks

ila_rendered

tap tap tap BANG BANG BANG SMACK

ila_rendered

Got ya! The amazingly brilliant brush strips can slide out now

ila_rendered

Only flipping Genuine Hoover aren't they!  8)

ila_rendered

Furniture guard removed

ila_rendered

Inside the brushroll area, which is usually ruined isn't too shabby either! The thing looks like it's seen mega abuse but deep down it's tidy as anything.

ila_rendered

ila_rendered

Brushroll clips removed

ila_rendered

Cable exit grommit removed

And we can have the motor apart!

ila_rendered

ila_rendered

Starting with basically removing all the wiring!

ila_rendered

And the supressor

ila_rendered

Little pile of bits building

ila_rendered

Last little bit

ila_rendered

These are the only 2 wires that we need now really!

ila_rendered

All this can be binned bar the screws which are of critical importance

ila_rendered

And one of the carbon brushes can come out

Which is also, although a rubbish picture, Genuine Hoover!

ila_rendered

The motor shell bolts can be removed now and the cover lifted off

ila_rendered

ila_rendered

And the other carbon brush removed. Both are excellent, decades of life in them with the use they will get from now on

ila_rendered

Fancase bearing clamp removed

ila_rendered

And the rear bearing clamp, then the whole armature and coil assembly lifts out

ila_rendered

The rear bearing pops off the armature

ila_rendered

Then the belt spindle, fan, all the spacer washers and front bearing can be removed from the armature

ila_rendered

The front bearing is servicable, the remains of the rubber gasket visible at the bottom

Underneath all the fluff the coil was spotless, sometimes these go rusty which tbh isn't a problem really as it's hidden but it's nice that this one isn't

ila_rendered

Both the carbon holders can come out

ila_rendered

The motor shells are stripped now, and again, I've seen much worse!

ila_rendered

ila_rendered

The washing box is full

ila_rendered

As is the screw card

ila_rendered

Throughout all of the above, the bag was in soak! I gave it a swoosh about every so often as I got up for a drink/toilet/numb leg, and this is what came out of it

And back in it went for another couple of hours, then got thoroughly rinsed out. The good thing about the vinyl-ette bags is they don't really hold the dirt when washed, it all just floats off, so no scrubbing required!

ila_rendered

The bag fill tube foam is dry, although heavily stained



Everything was washed and dried as normal, all the small metal parts run over the wire wheel on the bench grinder, and I machine polished the plastics

ila_rendered

ila_rendered

ila_rendered

ila_rendered

Not a sodding mark on it! In all my years doing vacuums this must be the cleanest non NIB junior I've ever seen! The bag got finished too around this point and hung up to dry



And I spent a few hours cleaning the cable! It's not ribbed though, and I did ask the fellow collectors if it should have been or not, and the answers varied from Yes, No and authorised Hoover cable replacement, as the wire ends are ring crimped and that never happened unless by Hoover. Either way, electricity flows and the cable is in good condition

ila_rendered

Time for the obligatory exploded diagram shot

And in go the carbon brush holders

ila_rendered

ila_rendered

The front bearing got a soak for a few days in Autosmart Tardis, which strips out ANY old oil and grease. It then gets filled back up with fresh oil, and the oil pad soaked through again for probably the first time in decades

ila_rendered

Spins as smooth and as free as you like now! First spacer on

ila_rendered

Then the washers

ila_rendered

Fibre washer that goes under the fan

ila_rendered

Fan

ila_rendered

And then the belt spindle to lock it all together!

ila_rendered

The rear bearing is a sleeve one, and technically should not have any lubricant. But, at it's age I dont think it hurts, helps take any slight wear out that's formed, although usually there isn't any

The whole shebang gets dropped into the motor housing now

ila_rendered

And clamped down, and checked that it's still smooth and free spinning

ila_rendered

Now what I do with Junior motors, is rather than find something to replace the little rubber rope seal that stops the backdraft from the fan filling the motor up with crap, is run a thick bead of silicone over the bearing clamp, then a thin bead around everywhere else, so once it's bolted together it's nice and sealed! It looks a pain to remove but I use cheap silicone (as it usually dries out before I finish the tube) so if someone opens it in 10 years time it'll all fall off/easily peel off anyway!

ila_rendered

Then just run round with a damp rag when screwing the 3 bolts in! (2 shorter ones at the front, long one at the back)

ila_rendered

Now to wire it up! I've refined my technique since this (October 2018 I did this!) but basically, the black cable that goes to the top carbon brush wants to go straight to one of the screw block terminals. Then, the red live needs hooking up to the switch, then the other side of the switch going to another terminal. So the live is switched, the neutral isn't. It also looks tidier than this as well, without the long wire runs flowing around the place.

More shots of the lovely hood

Usually I remove the firewall to clean it, then re-seal it back in but I didn't need to on this!

ila_rendered

Brushroll clips back in

ila_rendered

Then one last look at the clean underside

ila_rendered

Before dropping the motor in, and screwing it and the switch together

ila_rendered

Front axle re-build now, Nice smear of grease where the wheels will go to stop then squeaking

ila_rendered

And back together

ila_rendered

I found a better sized screw to fit the retaining plate, so it looks a bit better. Couldn't fit an original screw (I do have some) as the thread was buggared with the massive screw

ila_rendered

The handle bail was re-assembled with lashings of grease. Shame about the paint loss on this, but I'd make it worse by trying to re-paint it
