Makita BRUSH HOLDER CAP 7-18 GA7050/ - 643700-5
643700-5 supersedes older part numbers: 643710-2
Genuine Makita 643700-5 — Brush Holder Cap (screw-in) designed to secure the carbon brush and spring inside the motor housing; sold individually and listed in Makita parts diagrams as "BRUSH HOLDER CAP 7-18."
This hard plastic screw-in cap restores correct spring pressure and a dust-tight seal on the brush assembly, helping eliminate intermittent power or arcing caused by a loose or cracked cap.
Example compatible models include several Makita grinders, saws and demolition tools — for instance GA7021, GA7020, GA9020, LS1211, 2414B and HM1303 / HM1500 — making it a handy replacement when you’re servicing a corded tool.
Installation is simple: unscrew the old cap and thread the 643700-5 into the brush holder (a flat-head screwdriver is normally used to seat or remove the cap). This small original Makita part is a common item to keep on hand for routine maintenance of parts for power tools.
