Product Description

The Dyson DC39 main motor (part number 918954-03) is a genuine OEM replacement motor for the Dyson DC39 upright vacuum. This motor is the core power component that drives suction and brush roll operation. If your DC39 has lost suction, makes unusual noise, or won't power on, a faulty motor may be the culprit.

This is a direct replacement part engineered to factory specifications for the DC39 model line. Installation requires basic mechanical skill and access to the motor housing inside the vacuum head.

The DC39 motor is specific to this model and is not interchangeable with other Dyson DC series units such as the DC65, DC40, or DC33, which use different motor assemblies.
