How do I remove the drive belt cover inside the machine, I have had a chew on to get inside but It was getting late and dark and starting to lose it so job for tomorrow. Cannot split motor/filter casings. Do I need to strip the adjustble switch control to remove the belt cover ?

just that its lost its pick up, and has an itermintent whine/clicking when shutting slowing down. Both belts seem ok but reading other posts there is a clutch in there too ??
Suction pipes are clear and plenty of ummph but put your hand across sole base plate and its not very strong, are the brushes worn on the brush bar, and is there a tolerance for the length of bristle before needed replacement.

tried to follow a link on previous post but failed

I know you can clean the top filter with water, but what about the bottom filter, its black and it states lifetime but surely this must restrict the suction to the motor,

Thanks in advance

Hi, Just go to www.dyson-online.com and check out their technical advice section. The site is fantastic! Good luck.

I have seen service manuals for dco4 dco7 for sale on ebay which cover clutch & belt replacing.

Cleaned filters today, and stripped out the clutch and belts.

although the old clutch was working ok, I decided to replace it due to the cost £17 as drive belts are with it. (as it did have an intermitent rattle on shutting down). I dont think the suction has improved by fitting this clutch, but just makes the brush rotate as should, as they doesnt seem to have much suction on that sole plate, but remove the pipe and there is plenty of it, maybe the sole plate gasket is faulty ??

I dont think the motor is US as you would notice and probably here arcing within the motor ??

anyway the wife says its working better
