Cylinder & Canister Dysons / Re: Have Dyson dumped their 'cinetic science'?
« Last post by MVacs on May 22, 2018, 09:50:34 PM »
They say they are only moving forward with corded models but I haven't seen mention of dumping the Cinetic (filter free) models.

Having no filter was never the best idea anyway.............

Dyson DC07 / Re: How I repair DC07 Hoses

Glad it's helping! At first I was a bit skeptical of the longevity of the repair, but I've never had one back that I have done!

Dyson DC07 / Re: Question regarding the "fin type" part to the rod DC07

They are a pain in the arse, I remove them and never re-fit them!

All the brightwork got boxed up, and sent to Dorian, who is HooverLux on youtube, and a pretty bloody top bloke, who collects Kirby's. And as he collects Kirbys, he knows about polish and such, so worked his MAGIC

Once the parts came back, they really did look astonishing. I had the top motor cover on my desk at work all day!

Fun over, we can lay everything out

ila_rendered

And begin re-assembly. Which is where I am going to leave it for tonight, as I need to get to bed. Stay tuned for the re-assembly and testing, and to see if Stuart himself is happy with the results!

Bye for now

We are disassembled now! The bearings got a good soak in Tardis, then Petrol, which cleaned them up a treat, with a bit of brushing when the solution got changed to get the gritty stuff out

ila_rendered

ila_rendered

ila_rendered

ila_rendered

Turns out they are SKF bearings!

ila_rendered

I then discovered 2 more tiny grub screws

ila_rendered

Which came from here

ila_rendered

Which enabled the handle bail to be removed from the main chassis

ila_rendered

So all this could be boxed up

6
And the last picture in the last post shows the carbon brush holders and their insulating sleeves removed, a tiny grub screw holding them in!

Back to the top of the motor housing now, and the bearing itself has a protective cover, held in with the armature screw

ila_rendered

And it cane be removed as well, making the pair free!

ila_rendered

The motor serial tag was removed

ila_rendered

As was the exhaust vent diffuser, which rather than being a silly bit of foam like you get nowadays is actual metal

ila_rendered

The motor housing is/was sealed to the main chassis with sealant. This was not as flexible as it once was so was scraped off

ila_rendered

We jump back to the internal handle wiring and unscrew the wires from the plug

ila_rendered

Then clean the field coil

ila_rendered

ila_rendered

ila_rendered
7
Actual proper ball bearings!

ila_rendered

And the plate is empty!

ila_rendered

Crikey, my camera is going very black where I hold it now...

ila_rendered

But before we can remove the coil, we need to remove the handle bail plug to pull it all through

ila_rendered

The wires are soldered to the pins, and one snapped as soon as I looked at it funny

ila_rendered

But, because this is being re-wired, I cut the other one off as well!

ila_rendered

The protecting spring can be removed from the wires now

ila_rendered

And the field coil unbolted and withdrawn

ila_rendered

The bakelite carbon brush caps are unscrewed (the brushes came out from inside when we lifted the armature out)

ila_rendered
8
The circlip releases the top cap, under which sits a conical spring

ila_rendered

And under that spring sits a screw which holds the armature into the housing

ila_rendered

With that undone, and the 4 screws under the fan removed, the armature can be withdrawn from the motor

ila_rendered

I'm amazed these old motors run with the gunk on the field coil, I have seen loads like this!

ila_rendered

Possibly the main issue with this old girl is the carbon brushes, but there is a hack for that which we will look at upon re-assembly

ila_rendered

The fancase plate can be tapped off the armature

ila_rendered

Time to remove the bearing from the fancase cover, and another circlip holds it in

ila_rendered

Then a top cover plate and felt washer come out

ila_rendered

Then the bearing itself. And these old bearings really are a treat! No mass produced 608ZZ's here!

ila_rendered

9
Time to start on the motor, and wow! That is a pin, flung through the cast iron (I think) fan!

ila_rendered

Got rid of that before I gave myself TB or anything

Then the belt pulley got clamped, the spindle held still with a screwdriver and off it all cracked!

ila_rendered

ila_rendered

Under the fan sit the spacer washers and standoff

ila_rendered

Cripes, we have forgotten about the bag, let's go and have a look...

ila_rendered

Crikey, I bet you would catch all sorts of exotic diseases if you drank some of that...

ila_rendered

ila_rendered

That picture didn't show the thick layer of sand in the bottom of the bowl. I rinsed the bag under cold running water a bit until the water ran a bit clearer, then turned the bag inside out (or right way round, can't remember now) and refilled the bowl with fresh warm water and more detergent for another few hours.

Back to the motor now!

ila_rendered

But we need to be the other end, to remove this circlip

ila_rendered

10
3 more screws and the whole motor assembly lifts off the chassis. This is what is called a Coffee Can machine, before Henry Dreyfuss came along and hid it all under silly bakelite and new fangled plastic hoods

ila_rendered

Rear wheels now

ila_rendered

One comes off with a little circlip

ila_rendered

And reveals what looks like a grub screw, but is actually a long bolt

ila_rendered

With this bolt removed, and the adjustment knob spun up until it unscrews from the adjustment bracket

ila_rendered

The whole thing drops right off

ila_rendered

Then splits fully apart

ila_rendered

Sadly the adjustment knob doesn't come off, so I left it alone! Again, unobtainable...

ila_rendered

Bag flange bolts undo next, they unbolt from the rear and unscrew, they aren't coming off in a hurry
