Makita 517858-5 Spare Part - ARMATURE ASSY 240V HM1110C/111

Genuine Makita Armature Assembly (rotor) — part no. 517858-5 — direct-fit replacement for the rotor/commutator assembly in select Makita demolition hammers. This balanced rotor assembly is the rotating core of the motor (shaft, laminations and commutator) specified for the 240V motor version and restores smooth motor operation and torque when a burned or damaged armature is the fault.

Fits Makita HM1101C and HM1111C demolition/hammer drills — listed in Makita parts breakdowns and common spare‑parts catalogs as the 240V armature for those models. Makita parts listings may also show a closely related 110V armature (different part number) for other regional models; confirm voltage and model stamping on your tool before fitting.

Sold as the complete armature assembly (single unit, part no. 517858-5 / sometimes shown without the dash as 5178585) to replace a worn commutator, broken shaft or damaged windings — a practical, straightforward repair to bring your hammer back to service.

(If your tool’s model or voltage label differs from HM1101C/HM1111C, use the model/voltage stamping on the tool to verify compatibility before installation.)
