How to Replace the Brush Drive Belt on a Dyson Upright

Updated November 21, 2016

Dyson vacuum cleaners are some of the most coveted of vacuum cleaners; they're light, easy to use and efficient. They're also one of the few machines you can maintain yourself, an attractive feature for any do-it-yourselfer looking to save a little money. One part you may find yourself needing to replace is the brush drive belt. These belts can wear out over time or even break. Without the belt, the brush, which sweeps dirt and debris into the machine, will no longer work.

Ensure that the electrical cord is not plugged in. Lay the vacuum on its backside so that you have clear access to the underside of the machine.

Unscrew the three fasteners securing the brush plate to the machine. Using a coin or flathead screwdriver, turn each fastener a quarter-turn to the left. Pull the brush plate free of the machine. You will see the base of the belt attached to one end of the brush.

Remove the u-bend assembly. One end of the u-bend assembly is attached to the base of the hose while the other end is attached to the bottom of the machine just in front of the wheel. Push the tab on the u-bend assembly and pull the assembly away. This will allow access to one of three Torx bolts attaching the belt housing to the machine.

Unscrew the three Torx bolts securing the housing. The belt housing is located on the underside of the machine, between the motor housing and a short length of hose that connects to the cleaner head. Two of the screws are easily visible while the third can be seen through a narrow eyelet revealed by the removal of the u-bend assembly.

Pry the belt from the motor shaft using a flat head screwdriver. Pull the brush roller free of the cleaner head.

Fit a new belt onto the brush roller. Thread the new belt through the opening in the brush holder and carefully push the ends of the brush roller back into the brush head.

Fit the belt onto the motor shaft. Using the flathead screwdriver, stretch the belt over the motor shaft. Carefully push the ends of the brush roller back into the brush head.

Turn the brush roller with your fingers to ensure that the belt is fitted properly. Re-assemble the vacuum, placing first the belt housing and then the u-bend assembly and brush head back onto the machine.
