Description
Overview:
This Genuine Makita Yoke Unit (OEM 638989-8) is a core motor component for selected Makita cordless drill/drivers, including the BHP448 and BHP45. Built from durable materials with a rigid metal core and robust moulded carrier, the yoke forms the stationary part of the brushed motor and securely holds the magnets in place. By keeping the armature clearance correct, it helps the drill run smoothly, with consistent torque and speed. Replacing a worn, cracked, or heat-damaged yoke restores efficiency and reduces vibration, extending the service life of your tool. Designed to fit precisely in the motor housing, it offers a straightforward swap during routine maintenance or a full overhaul. Suitable for professional trades and DIY use across a range of Makita drill and combi drill models.
