Title: Hoover Constellation 852 - Stripdown, refurb (breakage) and improvement!
Post by: beko1987 on May 21, 2016, 02:33:03 PM
So, ages and ages and ages ago, I bought this from a fellow collector

[attachimg=1]

It ran like crap, but was complete, which is all you can really hope for with a constellation


It sat in the shed for a while whilst I refurbished Dysons for proper cash, went on holiday, worked etc, but the other sunday, the sun was out and I got it all out

[attachimg=2]

Unclipped the top

[attachimg=3]

and removed the new genuine bag and filter

[attachimg=4]

The lid is held on with a pivot bar, removed by removing a tiny circlip

[attachimg=5]

[attachimg=6]

[attachimg=7]

With the top off, the 3 screws that hold the middle plate on can be removed

[attachimg=8]

[attachimg=9]

We can now see the motor

[attachimg=1]

The wires start at the supressor, the black neutral wire comes straight from the cord, the red live comes from the switch. Both can be pulled out

[attachimg=2]

and the motor lifts out, it's only held in with the top plate and a lower rubber mounting

[attachimg=3]

I've not seen this part on all connies, but there is a white diffuser under the motor, with a kitchen scouring sponge as a post motor filter!

[attachimg=4]

I won't replace the sponge

[attachimg=5]

Let's remove the cord

[attachimg=6]

The top plate is thin wood, and is removed with 1 screw

[attachimg=7]

Cord clamp off

[attachimg=8]

The wire block is held on with the single screw removed earlier, so with the clamp off it flops about a bit

[attachimg=9]

and is all unscrewed

This was one of the main issues with the machine, the cord strain sleeve was broken, so most of the motor air escaped through the cable hole, rather than underneath where it should

[attachimg=1]

This clear part is the lower motor mount, and just sits on the bottom

[attachimg=2]

Switch now

[attachimg=3]

It's held in with metal brackets, which seperate with a flick of a screwdriver

[attachimg=4]

[attachimg=5]

and the brackets remove easily

[attachimg=6]

The switch is loose now, and the protective stiff paper is removed from the housing

[attachimg=7]

[attachimg=8]

Even the switch is made by Hoover

[attachimg=9]

The wiring loom can come off the switch now

[attachimg=1]

There's a wooden diffuser sat on the outlet port which comes off once the metal tabs are lifted

[attachimg=2]

Whilst moving the bits around, I found the top motor seal stuck in the top housing

[attachimg=3]

Onto the top now quickly

[attachimg=4]

The rubber bumper pulls off the perimeter

[attachimg=5]

The bag seal pulls off inside

[attachimg=6]

and the handle is removed with 2 screws underneath.

[attachimg=7]

Motor now, I'll point out where it goes wrong...

The lower motor rubber lifts off

[attachimg=8]

[attachimg=9]

The fancase is screwed on! No hitting it with hammers here!

[attachimg=1]

[attachimg=2]

Crack the top nut off, and the washer, top fan and washer come off

[attachimg=3]

Then, lift off the fixed part that was unscrewed with the screws earlier, then there's anotehr washer, another fan and yet another washer

[attachimg=4]

The lower fan was quite filthy

[attachimg=5]

We can now see the base of the motor

[attachimg=6]

which unscrews with 4 more screws from above. One of these screws has a nut and grippy washer attached, as this holds the supressor bracket to the motor

[attachimg=7]

With this plate removed, the armature can be pulled out too, leaving you with this

[attachimg=8]

Next, it's time to remove the carbon brushes, and it was at the stage I notices one wasn't plugged in...

[attachimg=9]
Title: Re: Hoover Constellation 852 - Stripdown, refurb (breakage) and improvement!
Post by: beko1987 on May 21, 2016, 03:11:42 PM
The other side shows how it should be connected

[attachimg=1]

The supressor can be removed completely now

[attachimg=2]

The carbon brushes pull out once unplugged

[attachimg=3]

Time to get the coil out, done by a flathead screwdriver and small spanner/pliers on the bolt the other side

[attachimg=4]

[attachimg=5]

I can't remove any of the top carbon brush holders as I would have to replace all the rivets, and the machine isn't quite concourse enough for that. And I won't remove the top bearing as I don't have another one.

[attachimg=6]

The comm looks good.

This is the bit you MUST NOT DO. If anyone knows where I can get the correct rivets from, please let me know!

Drill out the rivet tops, and remove the plate and oil trap

[attachimg=7]

Underneath, there is another plate, a cupped plate, another oil trap and the most lovely re-greasable bearing I have ever seen!

[attachimg=8]

Next, I drilled the 3 rivets out holding the skirt on to the machine base

[attachimg=9]

Floor tool now

[attachimg=1]

[attachimg=2]

Undo all 4 screws and remove the bottom plate

[attachimg=3]

The front lint strip slides out of each end of the base plate

[attachimg=4]

The brush strip lifts out

[attachimg=5]

as do the front wheels

[attachimg=6]

The swivel neck is held in with a wire and 2 screws

[attachimg=7]

Everything is now apart! Everything was washed, dried and polished. The bottom skirt was sanded briefly back, then spray painted with poundland silver wheel paint, to keep the rust off the carpet!

[attachimg=8][attachimg=9]

Title: Re: Hoover Constellation 852 - Stripdown, refurb (breakage) and improvement!
Post by: beko1987 on May 21, 2016, 03:48:54 PM
The skirt was then riveted back onto the base. One day, I'll run a bead of silcone around this, as a bit of air leaks around the join

[attachimg=1]

I then tried to re-assemble the motor, and even re-greased the bearing, however, when putting the fancase bearing back together realised my issues. I did try to bodge it with various bits, but they were no good, the head always caught on the first fan washer, locking the motor solid.

Annoyed, I had a beer and a rolly, then looked in the shed to see what other motors I had. I came upon one of these

[attachimg=2]

Which fitted in with some cut up dc24 rubber motor housing at the bottom, and the Quаltex and hoover motor rubbers on top

I quickly lobbed it all together to see if it worked


Which it did, rather well. So I finished it off, upgrading the filter as I went

[attachimg=3]

and gave it a quick test with all the tools


Then played with it for a few minutes


I then prettied it up, and cleaned the cable

[attachimg=4]

And the hose, which was filthy, and a bit fragile/worn

[attachimg=5]

It split on me whilst cleaning it

[attachimg=6]

which made the job finished a bit earlier!

[attachimg=7]

It's a bit shorter now, but tbh that makes it float around better as before the long hose pulled it down a bit, whereas now it keeps it lifted up.

And the afters!

[attachimg=1]

[attachimg=2]

[attachimg=3]

[attachimg=4]

[attachimg=5]

I've kept the original motor, incase I can find the correct rivets to fix it, but for now, this sure is fun! With 1200w rather than 550w, it works really well! Wonder what a 2200w Miele motor would work like... It does run hot though, after 15 minutes it's very VERY warm, presumably because the exhaust air is being held back, but meh, it's a laugh!

Nice job you did there.  :icon_nod:

I like those old Connies. I had one a while back but was unable to find the floor tool for it you have there.

Post by: beko1987 on May 21, 2016, 04:55:54 PM
If your one had had the floor tool id have been more interested,  but the problem with this age of Hoover are the tools,  no one makes them anymore,  and their so rare to find on their own! The hose on mine is perished,  if you bend it you can see strain marks,  thats where it split,  luckily on a bit I hadn't cleaned yet!

Post by: dysondc16 on May 21, 2016, 06:50:08 PM
Great job, shame about the motor. You certainly made the best of it though. Really would be fun to see a miele motor in it, wonder how hot it would get! Hope it doesn't melt the metal....

I guess we're lucky over here, constellations crop up fairly often (not usually in great shape admittedly). Yet tools and parts can still be found.

Post by: beko1987 on May 21, 2016, 07:01:31 PM
Yes,  you get much more choice of them in the US! And celebrities, so many celebrity machines!

I have been told that the motor I broke isn't actually the original motor! Its a later one introduced with the 867a. So I'm not as upset about breaking it now.

Ive been on Google too,  and need to borrow the micrometers from work and measure the rivet dimensions, must be something out there!
Title: Re: Hoover Constellation 852 - Stripdown, refurb (breakage) and improvement!
Post by: dysondc16 on May 21, 2016, 07:12:08 PM
We had a huge number of celebrity variants, we really are spoiled for choice!  8)

Good to know the motor wasn't original. I imagine there is some way to replace those rivets. I can't believe hoover would have developed their own fittings for that.
Title: Re: Hoover Constellation 852 - Stripdown, refurb (breakage) and improvement!
Post by: beko1987 on May 21, 2016, 07:13:36 PM
I can! Someone would have probably designed a special machine for fitting thrn too...  Maybe 4 tiny flat headed bolts and nuts... Its not urgent though,  I've used the carbon brushes from it for our new lawnmower now...

I used the connie quite alot yesterday upstairs (moving beds about etc) and the bags split somewhere, as the filter is covered in crap. Hopefully the hepaflo bag has kept it all the right side. Need to look at crafting some better bag onto it, the single wall Hoover ones can't cope with 1200w, even before it split the fine dust was coming straight out of it and onto the filter

If I can craft a Hepaflo bag onto it I'll put the original filter back onto it as the hepaflo bag should keep everything in, otherwise I'll need to write off another hepaflo bag to cut up, and I'm getting low on those, must buy another load on payday. I need to keep the numatic motor ok, as if I get a new motor job in for , it's coming back out to be used properly to save me buying another motor.

I have never done a full machine re spray, but need to/want to do it one day! What sort of finish can one get with a spray can? I've started learning, did the brushroll of the 1346 wit ha can of poundland spray and it came up OK, has a run or 2, but is hidden so not too critical.

My 652C will need a paint, as does my 417G, and the connie needs to not have a silver base one day, I just did it silver as I had a can, and wanted to cover the rust so it didn't mark the carpet!

Also Gareth, you'll know what I mean when I say do you know if the long rivets holding the fancase bearing in place are available anywhere? What are they called/what should I be searching for?
Title: Re: Hoover Constellation 852 - Stripdown, refurb (breakage) and improvement!
Post by: Vacuum Cleaner House on July 27, 2016, 10:06:48 PM
In my Hoover manual it says to replace them with bolt and nut combo.

I have used cans before, I like rustoleum as it gives the best finish but I often just use my compressor and spray gun.

Either way I always rub down and buff up the paintwork after it has set

I'm experimenting with poundland ones for now! Will probably get the Ford Ivory White from Halfords or ebay though.

When spraying old vacs, wether down to the metal or not, do you use primer anyone?
Title: Re: Hoover Constellation 852 - Stripdown, refurb (breakage) and improvement!
Post by: Madrat on July 27, 2016, 10:34:01 PM
If its bare metal, defiantly, if not it depends on the original paint finish. Halfords do a big can of appliance white, Its what I sprayed the Bendix in. Its pretty good.

I have never done a full machine re spray, but need to/want to do it one day! What sort of finish can one get with a spray can?

My inclination is to send them off for shot blasting and powder coating. Like we do with AB01 Airblade bodies.

Post by: MVacs on July 27, 2016, 11:57:51 PM
We use a place I have been using for about 20 years for wheels, gates and whatnot. Specialist colours take longer and cost more as they must set up the booth. Airblades are silver so go in with wheels. Black, silver and white they do every day. Other colours take longer.

But the finish is perfect!

I fancy doing a few Connies with modern cables and generic hoses and heads, powder coated in funky colours, to the retro folks.

Post by: beko1987 on July 28, 2016, 10:43:05 AM
Sounds expensive, and I really should have a crack with rattlecans first, just to learn (then I can fix the damage to Amys rear bumper, and paint the wing of my car...)

Connies themselves are quite cheap in 'needing paint' conditions, and if you can find a source of the hose adapters, any old 32mm shit will fit. You would do well to powdercoat complete ones in their original colours, they seem to fetch 100+ easily even with tools missing!

I'd swap you mine for some random dyson parts, but the 1200w motor makes it run bloody hot, and probably not suitable for daily use by some hipster tw@t. And I'm not faffing around with the original motor anytime soon!

Post by: Vacuum Cleaner House on July 28, 2016, 07:33:03 PM
Their was a guy on Vacland named Lee, His handle is hotpoint 95622 That has done a few , he has them powder coated aswell but I think he said it was rather pricey, I think about 80.00 or so. I know I got quoted around the same in Rands which is a huge amount of money to spend on a paint job considering I can do it myself in my spray booth I built just for this purpose.

Here is the link, the yellow one is awesome.

Bloody hell thats mint! But at the same time,  bloody hell 80!

Look forward to your post Gareth,  always been envious of your collection!
Title: Re: Hoover Constellation 852 - Stripdown, refurb (breakage) and improvement!
Post by: MVacs on July 28, 2016, 08:31:48 PM
80 isnt enough. You'd be looking 100+ really if a nice job like that and it was rewired and fettled properly.

We had issues mating a modern hose to the old hose cuff on those due to the diameter of the pipe. It would need to use something pretty standard like a Henry hose.
Title: Re: Hoover Constellation 852 - Stripdown, refurb (breakage) and improvement!
Post by: Vacuum Cleaner House on July 28, 2016, 09:21:25 PM
I think it was 80 just for the shot blast and powder coat. He took in just the parts to be done already stripped.

I prefer to do it myself.

Actually you can get that type of hose from Quаltex, It comes with two rubber cuffed on the end that you just fit onto the cuffs.

I would leave the original hose on the machine , they work well and last forever.

Lovely! I don't think we got the Senior in that colour scheme, the metalwork was an off white over here. That does look nice in the mint green though

I'm not a fan of those floortools on Hoovers. I've had a few, and find the angle too low to keep the head in full contact with the floor.

Post by: HaroldIllic on July 18, 2017, 07:08:31 AM
Bearing replace is quite easy if you ever give it a go But its an old hoover, it'll carry on like it is for years to come. You try turning a dyson on with a slightly poorly bearing... Progress eh?
