Remove the first flap using a flathead screwdriver or small coin to turn the mechanism to the unlocked position.
-
Use a T10 Torx screwdriver to remove all visible screws. Remove the secondary plate and any further screws. Note the location of the one long screw, the rest are interchangeable at this stage.

You now have access to the motor assembly. This can be removed from the body of the brush bar with some gentle twisting and tugging.
-
Once removed, you can use a 9mm socket to rotate a spiral mechanism and loosen the belt drive.
the belt tightening cam (spiral) has a ratchet underneath. loosen the screw, or take it off altogether

Use a T8 Torx screwdriver to remove the screw holding the spiral drive mechanism in place. This is the drive mechanism that spins the brush bar.
-
Use a thin flat device such as a spudger, screwdriver, or metal prying tool to lift the spiral drive piece off its axle.

You can now see one side of the ball bearing. This is where hair gets trapped if the brush bar is not cleaned regularly enough.

You can remove the hair and regrease the ball bearing from here.
I used small mole grips to pull off the spiral device. It was a tight fit.
Once off there was a lot of hair wound around and lots of dust in the bearing. WD40 and lots of working freed the bearing.
When re-assembling do not over-tighten the belt with the cam. Just enough to ensure the belt is straight between pullets with a little tension. Tighten the cam securing screw.
My spiral drive mechanism appears to have broken - there is a plastic piece that is actually inside of the spiral drive mechanism that the screw goes through. This entire spiral drive mechanism was severed from the spin brush holder - I took apart the screw and spiral drive mechanism and now have a severed plastic piece that I can't determine a part name / part number for... Any guidance would be appreciated! Thank you
If you can't find a replacement for the individual piece, you can try finding a whole new brush head, I'm afraid.
A) finding a replacement Dyson part on marketplace/ebay
B) buying a new replacement from an espares website.
I have cleaned out hair from behind the spiral drive a few times and somehow the screw has come out and been lost. Do you know what size the screw is that holds the spiral drive mechanism in place??
I haven't taken it apart again, but I think you could definitely try using one of the other screws in place of the spiral drive screw. Certainly don't need all of the screws on the outside of the case.
