Original Makita part 0031510000 — Outer snap ring (retaining ring) sized for 10 mm shafts. This genuine Makita snap ring is the small external circlip that secures pulleys/cover parts and keeps starter / pulley assemblies in place on small petrol trimmers and brushcutters. Supplied as a single, ready-to-fit retaining ring.
Example models that list this part include Makita RST250, RST210 and RST200 line trimmers, and a range of brushcutter / brushcutter-style engines such as RBC2110, RBC421L and EM4340L. Check the parts diagram for your model/type to confirm the same part number is used on your machine.
Notes for fitment: the part is listed as “Outer Snap Ring 10” (sometimes shown as retaining ring S‑10), so it engages a 10 mm groove on the shaft — replace if the groove or ring is worn or deformed. It is a direct replacement listed on Makita parts breakdowns and priced as a single hardware item.
