How to replace a belt and brush in a Dyson DC04

Hi, it's Jeremy from Crucial Vacuum.

In the link below you will find the user manual for your Dyson DC04:

Here a few repair tips to make fixing vacuum easier. Your Dyson brush-roll is connected to the motor by two different sized geared belts. Over time, the belt's gears wear down and stretch out losing the grooves and tension that turn the roller. Another reason why your brush is not spinning could be there is debris stuck on the roller and/or bearings. You can either use a can of compressed air to remove the debris or simply remove it with your hand.

The brush will not rotate when the machine is upright. The brush only rotates when it is reclined; in use.
On the side of the housing where you place your foot to recline it is a round knob. Turn it one click clockwise if you can; to the "auto" position.
If the brush doesn't turn then when the machine is reclined, it needs attention to the belt and/or clutch mechanism.

That model has a clutch unit from which the two drive belts are located. It is a technical job to strip that unit down to change the belts, so the easier solution if you have a snapped belt, is to replace the clutch unit (that comes with belts on it). A recycled one represents better value for money, and you can get one here: Dyson DC04 clutch unit.

Belt is broken. You will need to re[lace the clutch. Here is a video on how to do that.

More likely it is the beater brush which is jammed and not turning. Turn the machine over and remove the bottom plate. Unhook the drive belt, then try to turn the beater brush--it is likely bound up with string, thread, and hair. Try turning the machine on once--if the motor spins and makes vacuum, it is probably ok. Remove the brush assembly and clean it of debris. Clean the end bearings with a Q tip and WD40 oil, then wipe clean with another Q tip. Oil the bearings with 3-1 or other light oil. Check the belt for a badly burned area--replace if necessary. Slide the new belt over the brush and motor shaft, then drop the brush with bearings into the case, and check rotation. If ok, replace the plate and test on your floor. Hope this helps!

Remove the roller brush cover plate that is on the bottom and you will be able to access the belts. Here are the belts you need:

remove base cover by 3 'screws' 1/2 turn anti clockwise and clean well remove fibres replace cover and re try.

Hi,

Not sure why you claim clutch belts cant be changed because they can.
The DC04 DC07 DC14 all use the same clutch unit if you cant get the belts from your local vac repair shop look on Ebay they are on there.
The special tools are torx screwdrivers & if replacing both belts you will require circlip pliers.

How to replace both belts in manual form can be found here http://dysonmanuals.llc.nu/index.htm

The brushes on my dyson have stopped going round. I have checked it and they move freely by hand. The belt is intact. What could the problem be? The Hoover is about 10 to 12 years old.
My dyson is a dc04

I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure.
One of the main problems with vacuums are that the flat belts on the vacuums stretch and should be changed every 4 to 6 months or 3 or 4 times a year – you can tell by taking off the belt or belts on the vacuums and compare them to the old belts on the vacuum the new belts will fix inside of the old belts and you will be able to see the difference on how much they have stretched – if the belt is a geared belt – they stretch as well but should be changed about one a year – the cost is not that expensive and you cleaning will improve almost double – this also applies for the Dyson DC04 and the Hoover vacuum as well – some of the Hoover vacuums have two (2) belts and they both should be changed @ the same time.
