Makita 512881-5 — Armature assembly (for Makita 6906 impact wrench). This is the original Makita armature (often listed as "ARMATURE, 6906") designed to replace a worn rotor in the motor of the 6906 impact wrench.
Details: this armature assembly is rated for 115 V and is supplied as a complete rotor/commutator/shaft winding assembly — a direct-fit motor component that drops into the 6906 powerhead. The listed overall length is about 178 mm (7 in), matching the factory replacement specifications.
Why choose it: if your impact wrench is showing reduced torque, intermittent rotation, sparking at the commutator, or unusual grinding noises, replacing the armature restores proper rotor function and balance.
