Makita 513746-4 Spare Part - ARMATURE ASSY 110V HR3210/3540

Genuine Makita 513746-4 Armature Assembly (115V) — direct replacement rotor for Makita SDS‑max rotary hammers. This is the motor armature (rotor with commutator and shaft) used in the 115V/110V motor assembly; it restores rotating magnetic drive to the motor and eliminates excessive sparking, loss of power, or smoking that indicate a worn armature.
