Dyson DC39 - Stripdown and Refurb
« on: March 01, 2016, 09:33:22 PM »
So, (a while ago now), I refurbished my cheap DC39. The unblocking steps are in the 'much cheapness' thread. This will concentrate on the refurb.

It worked quite well before tbh

<a href="https://www.youtube.com/watch?v=iaRkbxRKwKM" target="_blank">https://www.youtube.com/watch?v=iaRkbxRKwKM</a>

This will not include the AirMuscle head that came with this, as I broke it... I will do a separate thread for that.

First things first, I needed to put a wash on. So out came the filter



Which was quite clean anyway

It strips down like so



Hose next



The clips pop off the machine end



and off the tools end



They went into the washing machine with some other bits.

The tools cant really be disassembled (and I lost the upholstery tool, more on that later...)



The extension wand does not come apart, but the red adjustment button does



Clip removed from the hose handle



and the end of the wand



On to the machine itself, and for this, you need small screwdrivers. My car boot special set came in very handy



We start with the front pivot part of the machine. Cyclone off, turn it over





Normal screws first





Wit ha bit of manoeuvring, the flexible hose part pulls up, which enables the main housing to be pulled down and off the locating peg thing

2 phillips screws here to hold the cover on for the flexible hose/cyclone locating part





2 stupid tiny screws hold the front of the front hose onto the main housing



The two parts now seperate



The hose pulls off the two ends



The pivoting part of the main housing is held together with a big circlip





The front wheel pops off in the way all front wheels do



The 2 middle wheels pivot with the machine, using a peg that located into the machine, and turns the wheels when the hose is pulled left or right



2 normal screws here, which when removed release a peg that runs through each wheel, and releases all it's mechanism



Some more normal size but proper short screws split the front housing in two



So far (ignore the musclehead screws...)



Main machine now



The top handle needs to be lifted further first, it's held down by 2 tabs that sit just inside the machine



Then it does this



Next, the wheels need to come off

https://lh3.googleusercontent.com/-r0I4C0SeUck/Vr-lrnpAEKI/AAAAAAAAxl8/Q4bzNFjA0K4/s800-Ic42/upload_-1.jpg



Lots of hair was wrapped around the inside



The retaining washer/part that sits inside the bearing is held on by another circlip each side





You may wish to try the wheels on like a hat, this is optional...



Next, undo the screws you can see from the underside of the machine, then flip it over and undo the screw each side that are on top



With luck, the motor housing will fall apart now



There is a very non dyson like diffuser inside the lower cover

The metal brackets that the rear wheels screw into screw into the main body themselves





To release the motor and filter from the top housing, prise the locating lug out on each side



and undo the 2 screws accessible from the top



and the philips screw that holds the park bracket in



be sure to catch all of the rubber motor housing bushes as they fall out



Stuff should fall apart now



Feed the plug back through the hole, and the top motor housing is now free. You can see how the top handle attaches inside the housing



it simply pops out either end



and is removed

The bar that locks the handle down, and moves to release it when you press the button sits under the top lip



With a little spring at the end



It simply pops out



The release button does pop out of the housing, but it requires 2 screwdrivers and I very nearly stabbed myself with one of them when the switch released...



Going back to the top handle, the plate that latches with the pivoting bar is held in with a screw



Both it and the big seal can be removed



Awful picture, but here is the motor assembly



The switch is the usual Dyson affair and is removed easily



The neutral cable join is covered by our old friend from the DC14 days



You can now let the motor fall out the bottom of the filter assembly



The cord rewind and power switch pedals unclip from the top of the housing





I could not figure out how to release the cord reel assembly from the post filter one



It comes apart this much, but there is no way of the plate coming apart to be removed from the cable, and it doesn't fit through the hole in the post filter housing

The post filter itself was a bit grubby but not too bad, and the suction is certainly good enough that I just left it alone



The cord rewind unit twists and locks onto the post filter assembly, and the cable guide for the motor wires lines up with the hole in the edge of the filter housing



With the cord reel unable to come apart any further, I moved onto the motor



Three tabs release the top cover. The seal is bonded to the unit



Three rubber bungs sit inside the motor housing and centre the motor up



The motor wires sit around the outer edge of the motor housing



The motor lifts out, and the wires disconnect



The motor loom pulls out of the housing



Comm looks healthy



That part done, onto the cyclone



Bin off



The bin release rod unclips from the side of the bin



The bottom flap pops off the bin with a quick squeeze under the arm, and the seals upon it are removed



The cyclone shroud is held in with very shallow clips. They don't need prising out much to pop off





Next, all these screws need to be removed. They are very small, and will be full of crap so are hard to undo



The finish has worn away with all the grit that will fly around this top part (they are exposed to the dirt path)



This splits the cyclone apart a bit



Rubber seal lifts out



and the inner cone lifts off each little cyclone one by one



Buried inside the cyclone are more tiny screws, that luckily my very long smallest driver just about undid. This releases the top of the cyclone



The foam gasket is in good condition



The cyclone top splits down even more



The last tiny screw secures the tiny cyclone handle on





Done, she is stripped!

And washed, and polished and mostly laid out





Cyclone bits first



Cyclone handle refitted



Cyclone gasket refitted



The two white bits are bought together and sat ontop of the main unit



and screwed in



Inner cone is clipped onto the cyclone tips



The outer part of the cyclone is screwed down, and I was crafty and used the screws with the worn finish inside the cyclone, and the nice looking screws that were inside on the outside so it looks better



Shroud clipped on, it really is damn flimsy when off!



Bottom flap sealed up



Filter clipped back together



and fitted



Onto the machine now. Motor loom run into the housing, plugged in and motor dropped home







Wires re-routed



Pedals and switch refitted, motor housing rubbers fitted then mated with the filter housing





Handle now. Seal on and retaining bar fitted



Button and spring fitted



Latch fitted



Fit the top handle but don't pop the lugs under yet



This was a bit of a pain, refitting the motor assembly into the machine. One lug snapped right in, the other required a bit of persuasion that luckily is hidden behind the wheel





Screws fitted



and the spring that makes it pop up



Now you can clip the top handle down



and screw the tool holder in



Now it's time to mate these two together



Fit the diffuser



and fit the lower housing. It's much easier to turn the top part upside down, as the motor isn't held in, which makes for hilarity when trying to lower the top part down...



Screws falling fast



Hubs fitted



Wheel centres circlipped back in



and screw them back on



Front pivotey part now



This bit is removeable, I didn't realise. Pointless to do though



Screw the two halves together





Fit the pivot bar and wheels



Front wheel



Fit the lower part



and the top part





Fit the hose back together





and fit it, making sure the lug fits in the pivot bar



Fit the top cover/cyclone holder



then fit and screw all that to the machine, being sure to fiddle the whole thing onto the big peg it needs to sit on...



Pop the cyclone back on, which is a fiddly horrible job in itself





Next, clip the hose and pole clips back on





Pop the tool holder back on



Bloody upholstry tool is still missing







Now, because I broke the Musclehead, and want to ebay this for much , I bid and won some cheap new heads. First, a plain, boring carpet and floor nozzle



Then a swanky swish Triggerhead





And sunk a scary 10 on a new upholstry tool



Total now 44.55, I took some ebay pictures











The triggerhead cuts off if too much power is applied

But worked fine on the DC39!

Done!

As usual, I enjoy reading these threads ;D :Thumbsup:

I always wonderered, how does the top of the cyclone seal with the duct? I can't see any seals and that's just connecting to a filter :s
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.

Thanks Dilys!

Tayyab - There isn't a rubber seal on the bit that clips into the top of the filter, but is a big rubber seal under the moving part of the filter housing, so that must seal it up when clicked down, that or magic! (just not done by Paul Daniels...)

This just sold for 82. Not too shabby,  would have been a better profit if I hadnt broken the musclehead,  but then I did go crazy and buy 2 new ones...

THANK YOU VERY MUCH !!!! Great detail with the pictures. I'll give it my best after work. The process of pushing or prying in the visible larger white clips on each side of the top is what I am having a hard time with . Its hard to put enough pressure on them at the same time to release the top. It seems as though something may crack or break before they get to the point of release. I have use a smaller flat head screw driver on each side but it seem to get tighter and not move as i try to separate the two parts.????? Could you advise me on what tool worked for you ? Thank You very much for your time .

I used a small/medium nice sharp thin ended flatblade, but found that one side popped out, then the other, IE probably impossible to do both at the same time, but the plastic flexes enough to pop one side out at a time

 Thank you very much. I did just that hoping not to distress or break the plastic . It came apart as you said. You just do not know at times how much stress plastic can take. I did notice after removing the on/off switch and taking it apart that carbon had accumulated between the contact points and was able to clean it off with a small pick but was unable to reassemble it because a very small 90 degree pin on the inside came apart with it and i am unsure how to place it back in the switch. if i knew where to place it i am sure it would work good as new. i already had purchased a new one from amazon so all is good. thank you very much again

Thanks for this.
Those filter holder lugs are difficult to get out and didn't quite go back in  :whist11:
