Dyson DC27 Cyclone Unit - How to strip and Refurbish
« on: February 19, 2015, 12:07:03 PM »
This is the cyclone unit from a Dyson DC27, that the owner wanted me to have a look at and clean it up



Firstly, seperate the bin from the cyclone



The bottom flap comes off the bin by squeezing the bin udner your arm until the tabs pop out



The release rod pulls out of the bin assembly



And the seal comes off the bottom flap



Onto the cyclone now. The cone pops out very easily from the bottom of the shroud



and the bottom seal pulls off the cone



Onto the top now



The bin release button pops out of the handle



removing the 7 screws removes the top cover



2 screws on the handle enables the handle to be removed





7 further screws hold the seal housing onto the cyclone unit



which can be removed and reveals a VERY worn cyclone seal



Several locking tabs release the shroud from the cones



The middle part of the bin release flap can be removed now



this seal sits between the two halfs



This springs out of the release button for the bin



And she is apart!



All washed and cleaned, it can be re-assembled

Rubber seal back into the shroud



put the spring back onto the release button



and bring the two halfs back together. The spring can be a bit tricky to get in place, but it gets there. Dont forget the middle part of the release rod!



The very worn cyclone top seal is palced carefully back into the top cap



and screwed down



top seal for the bin is refitted now



Top handle screwed back down



Top part of the release rod pushed home



Top lid screwed down



Bottom rubber onto the cone end



and the cone can be refitted to the shroud



Outer seal refitted to the bottom cyclone flap



last part of the release rod can be fitted to the bin



Bottom flap can be bought home to the bin



and once the bin is refitted to the cyclone, the job is done!



If you have reduced performance, and new filters, checking for blockage and cleaning all the rubber seals you can see don't fix it, this might be your answer!

You might have replaced that worn rubber gasket.  ;D

She wouldn't pay me to do that! Wanted to do a full refurb as the machine was utterly ruined,  struggled to get 20 out of her for a cable repair and changeover valve fix,  did the cyclone because I was bored!

That lady seems as ignorant as the one selling "my" DC40 😠😡
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.
