Dyson DC23 - Stripdown and Refurb (and turbo tool repair)
« on: July 13, 2016, 10:58:59 PM »
This came my way a few weeks ago now via my facebook repair page. Never had one before, so let's do this!

The main complaint was the turbo head did not spin. A quick test revealed that something did spin, but not the brushroll!

I cover the stripdown of this in more detail later, but basically you take the turbine housing

ila_rendered

split it all apart until you get to the fan

ila_rendered

which you will hopefully find cracked but not irrepairable, so glue it up

ila_rendered

refit and test! In this case, it was job jobbed. The fan wasnt too worn, and worked a treat. One message to the happy owner later to say it should work, but if it breaks again we can look at a replacement fan, we can crack on with the main event!

ila_rendered

ila_rendered

Tools off

ila_rendered

First off the machine is the cyclone seal

ila_rendered

ila_rendered

Removing the torx screw that sits just behind it releases the whole hose holder bit, and it slides/pulls off the machine (it's quite fiddly)

Like so

ila_rendered

There is another screw sat underneath it now

ila_rendered

Which releases the hose wrap guide

ila_rendered

One last screw in here

ila_rendered

and the floor tool parking bracket comes away

ila_rendered

The rest of the assembly does look like it will split further, but I could not work out how to do it, and being a customers machine, and not one that I bought for a fiver, I left it alone to avoid damage!

Filter housing open now (hose and filters had already gone through the wash)

ila_rendered

The hinged cover pops off the pivot very easily. The wheel, not so, and it took rather alot of force to pop the wheel off (it came off with a loud crack too  but no damage)

ila_rendered

The airflow channel lives on the outside of a DC23, and 3 screws remove it's cover. If the rubber seal stays fixed to the cover, leave it on! It's a proper fiddly bastard to get back on, trust me!

ila_rendered

4 screws release the filter housing part from the main chassis

The release valve sits in this part, twist the top cover and the whole lot flies/pops out depending on how your holding it!

ila_rendered

Sat under the pre motor filter cover is the post motor filter, which lifts out

ila_rendered

Very carbon dusty but not too bad

ila_rendered

ila_rendered

That's about it for this side now, onto the other, and snap the other wheel off

ila_rendered

The next step seems to be to remove the outer shell. Lots of screws dotted about

ila_rendered

2 either side of the wheel holder

ila_rendered

The hose entry port also forms part of this

ila_rendered

and lifts off once unscrewed

Once unscrewed, it lifts off the machine, although the cable is still running through it

ila_rendered

The cablue guide is held ont othe top shell with a screw

ila_rendered

and this clip here

ila_rendered

The rewind pedal fits on like any other Dyson cylinder

ila_rendered

This part is not removeable without un-wiring the cable from the reel, and sod that, so it gets left on!

ila_rendered

The front wheel pops off

ila_rendered

The power switch sits on a little stand, held on by a screw

ila_rendered

The cables running through it like so

ila_rendered

the red cap pops off, and the switch slides out

The wires run through various channels, and the red one to the cord rewind loops down then back up (I took a pic during re-assembly)

ila_rendered

The cord reel is removed by pulling it out until the square peg clears the chassis, then lifts out

ila_rendered

The live and neutral connect to the reel like so, and need to be removed

ila_rendered

Done! Not touching it anymore

ila_rendered

Behind the cord reel sits the motor housing screws.

ila_rendered

These are machine screws

ila_rendered

Luckily there are cutouts in the main chassis to help with this

ila_rendered

With the last screw out, the motor housing falls out the other side

ila_rendered

and unscrews like so

Once unpeeled, the fancase seal can be pulled off

ila_rendered

And the little cooling fan removed. The spring slip pops off, and the fan pulls off the keyed shaft. I've never seen thsi type of motor before, but since Mvacs list it under the DC23 spares section, it obviously exists!

ila_rendered

A lesson from Dyson in how to make a repair more expensive than it needs to be, the whole motor is physicaly the same size as a DC05/8/most other cylinders, but this little shaft makes it unique, and I don't know what will happen if you try to fit a non cooled one

ila_rendered

ila_rendered

The empty chassis means we are done with the main machine

ila_rendered

So, it's out into the garden to deal with the cyclone assembly, which is a tad dusty...

ila_rendered

Bin off

ila_rendered

The red release rod pops out of the channel on the bin

ila_rendered

The bottom flap is removed from the bin

The 2 rubber seals pull out of the bottom flap

ila_rendered

Onto the main cyclone now, and the first place to start is with screws

ila_rendered

Which reveals this

ila_rendered

which was a tad dusty

ila_rendered

The shroud pops off 4 very shallow clips

ila_rendered

The main shroud-cones seal is 2 parts, a palstic cage and a rubber gasket, which once you pop off every cyclone comes off

ila_rendered

Hidden deep inside the cyclone are some screws

* pic_20160622_212512.jpg (209.99 kB. 848x736 - viewed 19 times.)

which releases both the inner cone and top cover

ila_rendered

The top part goes top cover, plastic cover, rubber gasket, cones

The cones side of the gasket was filthy

ila_rendered

The middle part of the release rod sits in it's housing, ontop of a spring

ila_rendered

The park bracket for the tubes screws onto the side of the cyclone

ila_rendered

Finally, the bin seal is clipped over several lugs on the bottom of the cone assembly, and lifts out

ila_rendered

I went to remove the top handle, and found a screw to undo

ila_rendered

but no matter what I tried, it would not come off, and again, through fear of damaging it and needing to fork out for replacement parts, I left it alone!

ila_rendered

Turbo Brush Now

ila_rendered

Flip it over, and remove the base plate

ila_rendered

Twist and pull the brushrolls off the axles

ila_rendered

Undo all the screws you see at the top

ila_rendered

and remove the cover.

The pivoting part needs to be split now. One side of it pops out with a flatblade screwdriver

ila_rendered

ila_rendered

The 2 halves seperate easily now. The rubber seal joins the turbine housing to the chassis, and the round hose is the internal hose for the turbo brush

ila_rendered

The machine is now apart! Everything was washed, polished, dried and dumped on the front room rug for re-assembly!

ila_rendered

We start with the cyclone, and the bin seal

ila_rendered

The seal has a unique part, that mates with this bit on the cyclone assembly

ila_rendered

then the rest fits fine

Wand parking bracket back on

ila_rendered

Middle bin release rod back in

ila_rendered

The much cleaner cyclone gasket is pushed onto the cyclone top

ila_rendered

and fitted to the cyclone assembly

ila_rendered

The inner cone gets fitted now

ila_rendered

and with the top outer lid fitted, the whole lot screws up

ila_rendered

The white ring slots onto the cones

ila_rendered

and the rubber gasket sits ontop of that

ila_rendered

The outer cone screws on

ila_rendered

and the shroud sits on top of that

Bottom flap seals back in

ila_rendered

Bin release rod back in

ila_rendered

Bin flap fitted, bin fitted and the cyclone is done!

ila_rendered

Motor next, and the cooling fan air ducting sits ontop of the motor, forming the top motor mount in the process

ila_rendered

Fit the fan and retaining clip

ila_rendered

Fit the fancase seal, and then fit the motor casing, taking care to route the motor wires through correctly

ila_rendered

ila_rendered

The motor housing fits into the chassis one way, so fit it that way, and screw the screws in. Be careful though, I crossthreaded one very very easily!

ila_rendered

Release valve fitted back into its little house

What can I say, your refurb is outstanding as usual ;D
The cyclone looks like a DC40/41 design except for a diff shroud! I never understood why the motor needed a cooling fan either  :boggleeye:
DC14s are tanks, just need a slightly longer motor life. Do plastic parts often break on DC14s? Nope. DC41- Sexy looking futuristic and powerful machine. Just needs a better designed cleaner head wheel and cyclone clip along with a dense metal rod in the chassis.
