Genuine Makita Armature Assembly — Part 515616-3. Direct replacement armature (115 V) built to factory specification for compact Makita angle grinders. This assembly restores reliable motor rotation, reduces arcing at the commutator, and brings back original running speed and torque. Makita spare parts like this are made with copper windings, a precision-machined commutator, an integrated plastic cooling fan and the armature bearing included to simplify the repair.
Fits common compact grinder models (confirm your model plate): 9553NB, 9553NBK, 9554NB, 9554NBK, 9555NB and 9555NBK. It’s the specified armature part for those 115 V Makita grinders.
Quick install notes: replace brushes or relieve brush spring tension before removing the old armature, pull the rotor out after removing the gear housing, and press the new armature into the bearing plate—typical bench-side swap that gets the grinder back into service.
Part number: 515616-3 — use as the exact match when checking your grinder’s parts breakdown to ensure compatibility.
