The Dyson DC14 vacuum cleaner is a quality vacuum that a number of homeowners use to keep their carpets clean. The vacuum uses a belt much like any other vacuum. When the belt breaks or becomes stretched, it is necessary to replace the belt to maintain the cleaning power of the vacuum. Changing the belt on a Dyson DC14 vacuum cleaner is a bit different than most vacuums. The belt slips through a hole between the agitator housing and the vacuum head. The hole resembles a small tunnel that leads to the motor spindle.
Turn off and unplug the Dyson DC14 vacuum cleaner. Remove the wand from the vacuum cleaner.
Sit in a chair and hold the head of the vacuum with the bottom pointing toward you. Look for the three fasteners on the bottom rear of the bottom plate. Remove the fasteners with a flathead screwdriver.
Grasp the sides of the bottom plate near the brush agitator and slide the bottom plate back and off the vacuum.
Grab the brush agitator at both ends and pull it straight up and out of the vacuum. If the belt is still intact, hold the belt and pull the brush agitator away from the belt. Unhook the belt from the motor spindle and pull it straight out of the hole in the vacuum. Remove all pieces of the belt, if the belt is broken.
Feed the replacement belt through the hole where the brush agitator sits and loop the belt around the motor spindle. Insert the brush agitator through the belt until the belt is on the belt channel of the agitator.
Push the brush agitator into the vacuum. Some pressure is necessary because of the belt. Position the bottom plate on the bottom of the vacuum and slide it forward. Secure the bottom plate with the securing screws.
Use a quarter to remove the three securing screws if you do not have a flathead screwdriver handy. Remove any hair and other fibres from the brush agitator while you have it out of the vacuum.
