Makita Genuine 513888-4 Armature Assembly 240v for Makita HR4013C Rotary Hammer

The Makita 513888-4 Armature Assembly is a genuine OEM replacement rotor for the Makita HR4013C rotary hammer, designed to restore full motor performance at 240V. Built around a precision-balanced laminated steel core with tightly wound copper coils, this armature delivers efficient power transfer and consistent torque output under load. The multi-segment copper commutator maintains stable brush contact and helps reduce sparking during operation. A moulded cooling fan is integrated into the assembly to support airflow through the motor housing, helping to manage operating temperatures during sustained drilling or chiselling work. This makes it well suited to contractors and site engineers using the HR4013C regularly in concrete and masonry applications.
