Introduction

This guide will show you the necessary steps to replace the motor in your Dyson DC14 Vacuum. This is a lengthy process; you should set aside a good amount of time to finish this guide in one attempt.

Turn off the vacuum and unplug it from the outlet.
  • Turn off the vacuum and unplug it from the outlet.

  • Lay the vacuum on its top so that the brush bar faces you.

Turn down the squared tabs on the brushbar so that they face outward. Use a screwdriver to pry the belt up from the brushbar.
  • Turn down the squared tabs on the brushbar so that they face outward.

  • Use a screwdriver to pry the belt up from the brushbar.

    • Be careful not to cut the belt with the screwdriver.

  • While holding the belt, pull the brushbar to the left and remove it from the vacuum.

    • You can let go of the belt when it's free from the brushbar. The belt will not retract into the vacuum.

  • During reassembly, insert the brushbar with the tabs facing outward, then rotate the tabs up to lock the brushbar in place.

Some models don't have the clutch mechanism, but are driven directly from the motor (and the belt cover which is shown as the clutch cover is now part of the soleplate); in that case, it may be simpler to just remove the belt from the motor spindle.

If you've had the vacuum cleaner more than 2 or 3 years, consider changing the belt at the same time, they are not expensive

Insert flathead screwdriver under each latch and pry up gently. Do not try to lift the latches up very far, they could snap off! Open the cover, remove the exhaust filter, and set the filter to the side

Some DC14 units don't have the clutch mechanism (the motor drives the rotating brush directly with the rubber belt), and the "cover" is now part of the soleplate (removed in step 2), so just skip this bit....

Insert a flat-head screwdriver into the two locking rings to remove the rings, which are located above the wheels on both sides. These rings secure the bottom assembly of the vacuum to the rest of the unit.

  • Remove the elbow-bend pipe on the right-side of the vacuum.

    • Press the two release latches on either side of the elbow-bend pipe. Pull it out and away from the vacuum.

Don't confuse the top left screw with the (non-recessed) screw that holds on the small piece of pipe.... the one you are looking for is recessed like the top right one.

I found a 5th Torx 15 to the rear of the Right Hand side, holding the Motor Housing cover on. Once this was removed the Housing came off easily

Rather than use a screwdriver for belt removal & risk injury or machine damage, why not use the proper belt tool ?. It saves time & possible injury and is available for not much more than the cost of a decent quality flat head screwdriver.

Great guide! A useful tip for getting the motor (or specifically the rubber cover) into the motor case: smear some washing up liquid or liquid soap around the inside of the motor case, and the rubber will slip in a lot easier. Keep an eye nf the rotational position of the motor (so that it fits the hole at the axle end correctly), and make sure you don't trap the 2 power wires.

Great tutorial, replacement motor cost £12, Dyson now back up and working. Only issue I had was that when replacing the motor housing in the Hoover, make sure it fits into the bottom groove or else the screw hole on the brush clutch cover won't line up. You'll know it's not in the groove if you're having trouble with the screw. Just go back and under the four screws, lift out the motor housing and seat it in again, that'll sort it out.

Belt not broken but brush bar not rotating is the pulley spindle worn or has the belt slipped off the pulley spindle the motor is still in working order.

Any suggestions to diagnose the fault.

dismantled all the bits and then ordered a new motor. I must say it went back together a bit easier than taking apart. Proper tools helped. As a female I found the instructions very easy to follow! My husband sat and watched and gave the usual male comments. Would know what to do next time. New dyson motor 52.00. Lynda Richards 4th July

Thanks for the guide, Dyson (Australia) didn’t want to know said the unit was too old and they wouldn’t supply parts anymore (this is our 2nd replacement motor in 10 years) so rather than drop another $1,000 on a new model, I thought I’d have a go myself after sourcing the genuine parts from the UK.
