How to Replace the Belt on a Dyson DC04

Over time the drive belt in your vacuum cleaner can become loose or perish from wear and tear and even snap; casing the performance of your cleaner to deteriorate.

If you’ve noticed your Dyson DC04 losing its suction, a possible culprit could be the drive belt. In this video we will demonstrate how simple it is to replace the drive belt, without breaking a sweat.

This video shows an example on how to remove or replace the part on a typical machine, some models may be different but the procedure should be similar.

  What You Will Need:

Drive Belt

Flat-Head Screwdriver

  Step 1 - Safety Advice

Safety First! Please ensure that you have disconnected the appliance from the mains before starting any repair.

  Step 2 - Accessing The Drive Belt

Now to get to the belt, we need to turn the vacuum over. In order to do that we need to take the cyclone and bin assembly off, and then remove the post-motor filter too. This isn't essential but removing the parts will make it easier for you to work on the machine.

  Step 3 - Removing Faulty Drive Belt

Now to turn the vacuum cleaner over and remove the soleplate to access the belt. To remove the soleplate undo the locks with a flat head screwdriver. Once the locks have been turned 90 degrees, the soleplate will pull away.

We can now see the drive belt running around the brushroll and then around the motor spindle.

Start off by removing the belt from the motor spindle. Using a flathead screwdriver lift it up and back and just coax out the belt with your finger. Now we can now pull away the brush roll and pull the old belt through.

  Step 4 - Refitting New Belt

With the old belt out you’ll notice the new one isn't as big as the old one and this is because obviously it hasn't been stretched as it hasn’t been in action yet.

So now to replace the belt. Pop it back around the brush roll, feed it through the assembly and then put the brush roll back in place; making sure it’s lined up correctly. Now, we just need to put the new belt back on, to do that again, use your flathead screwdriver, pull the belt towards the motor spindle and just put the lower side of the belt around the motor spindle.

This can be a little fiddly to get the belt on the spindle, once you’ve that spin the brushroll a few times to check and ensure the belt is lined up. All that’s left to do is to put the soleplate back on and get everything put back together.

There you go! New belt fitted and it couldn’t get any easier. We hoped this video has helped you restore your vacuum cleaner without the headache of purchasing a new vacuum.
