Original Makita 221450-8 — Spiral bevel gear No. 10. Precision-machined small bevel/pinion gear used in the gear train of Makita 125 mm random-orbit polishers and polish/sander models. It replaces the worn small bevel gear in the gear housing and restores smooth, low‑play engagement for the orbital drive.
Fits (example models): PO5000C, PO6000C, DPO500, DPO600 — listed as the “spiral bevel gear 10” in Makita parts diagrams for these polishers.
Part details to check before fitting: designated gear “10” (the small spiral bevel in the assembly) designed to mesh with the internal spur gear (part 221453-2 / internal gear 29) in the PO5000C/DPO500 gear set — match tooth profile and seating in the gear housing for correct fit and smooth operation. This is an original Makita replacement part.
Quick benefits: restores correct gear engagement and orbital action, precision tooth profile for quiet running, and drops into the original gear housing without modification.
