Original Makita 638420-4 — Yoke unit (stator) designed to replace the magnetic/coil assembly in the motor housing and restore proper motor operation. This genuine Makita yoke unit is the service part used where a burned, noisy, or non‑starting motor indicates a damaged stator assembly.
Example fitment (selected models): Makita BPB180 (cordless band saw), BCS550 / BCS550F, BSS500 / BSS501 (cordless circular saws) and BUB360 (leaf blower) — a good match when you need genuine Makita parts for power tools to get a single tool back into service. Confirm fitment against your tool’s parts diagram or model plate before installation.
