Hitachi 323-164 Spare Part - Brush Holder

Original Hitachi brush holder — part no. 323-164. A direct-replacement brush holder for Hitachi / Hikoki cordless rotary hammers, this unit is the molded holder assembly that secures the carbon brush, provides the spring contact and metal terminal for the brush lead, and mates to the tool’s stator wiring. It’s supplied as a single brush holder

 Example models this part fits: DH25DAL, DH25DL, DH36DAL, DH36DL and several DH24 series cordless rotary-hammer models (DH24DV / DH24DVA), as shown in Hitachi/Hikoki parts diagrams and spare listings. Use this brush holder when replacing worn or broken brush seats that cause sparking, intermittent power, or poor contact.

Why this part matters: the 323-164 brush holder keeps the carbon brush aligned and under spring pressure against the commutator; replacing a cracked or burned holder restores reliable electrical contact and reduces arcing that can damage the armature. It’s a simple, small plastic/metal assembly — install in the same slot shown on the tool’s parts diagram and refit the matching carbon brush for best results.
