Makita 643807-7 — Genuine Makita Brush Holder Cap. This original Makita replacement cap secures the carbon brush assembly in the motor, keeping the brushes seated for steady electrical contact and protecting the brush area from dust and debris.

Made from hard-wearing molded plastic with a durable finish, the cap is engineered to match the fit and finish of the factory part and installs with basic hand tools — a like-for-like replacement when the original cap is cracked, missing, or worn.

Fits (examples): 6339DWDE, 6347D, BSS500 / BSS501, BJV140 / BJV180, DJV140 / DJV180, DSS500 / DSS501, DCS550 / DCS552 and related circular saws and reciprocating saw models that use the same brush-retaining cap. Confirm fit against your tool’s parts list or model number before ordering.

Part number: 643807-7. Replace this cap to restore proper brush retention and keep your Makita tool running reliably.
