Makita 743341-8 — Brush B (carbon motor brush) for concrete planers. This is an original Makita carbon brush (Brush B) designed to replace the worn brush in Makita concrete planers; it’s listed as the Brush B service part for models PC5000, PC5000C , PC5001 and PC5001C.
Compact and ready to install — the contact/segment height is 14 mm, and it’s supplied as the single Brush B unit used alongside the matching Brush A (part 743340-0) in the tool’s brush assembly.
If your planer is showing reduced power, sparking at the commutator, or intermittent running, replacing this brush restores reliable motor contact and normal performance without needing extra parts.
