Genuine 3 Armature Assembly BHP451 BDF451 Hammer Driver Drills

The Makita 619165-3 Armature Assembly is a genuine OEM replacement motor component designed to restore full performance to compatible Makita hammer driver drills, including the BHP451 and BDF451. The armature sits at the heart of the drill's motor, converting electrical energy into the rotational torque that powers the chuck and hammer mechanism. Constructed with a laminated steel core and copper windings, this assembly is built to withstand the demands of regular on-site use. When a drill begins to show signs of power loss, overheating, or rough running, a worn or damaged armature is a common cause. Fitting this genuine Makita replacement restores the motor to its original electrical characteristics, ensuring consistent torque output and smooth operation without the need for modifications. Engineered for direct fitment, the 619165-3 aligns precisely with the existing motor housing, bearings, brush gear, and field coil in the specified models. The pre-assembled unit simplifies the repair process, making it a practical choice for professional service technicians and experienced tradespeople carrying out workshop or on-site repairs.
