Makita 257430-8 — Retaining ring (external) 18 mm
Restore the assembly retention on your Makita saw with this genuine Makita external retaining ring (marked “18”). It’s the precision snap ring that seats in the machined groove to stop axial movement of sleeves, bearings and pins in the drive/blade-clamp area — exactly what you need when a worn or missing circlip is causing play or a re‑build. Fitted easily with standard circlip pliers and made to the original specification for fit and spring tension.
