Original Makita 233989-9 — RING SPRING 14: a small, hardened ring spring used in the bit-holder/tool‑sleeve assembly to retain the guide washer and adjacent components (listed on Makita parts breakdowns as “RING SPRING 14”).
This genuine Makita spare parts item is sized and referenced by Makita as “14” (fits the chuck/tool‑holder stack next to washer 16 and the guide washer) and is supplied as the single ring spring needed to restore proper bit retention.
Example models that use 233989-9 include a range of Makita rotary hammers such as HR2631F/HR2630, HR2663, HR001G, HR2300/HR2600/HR2601/HR2610 (and other related HR-series models shown in Makita parts breakdowns).
If the retaining spring in your tool’s chuck or sleeve has failed or fallen out, replacing it with this original Makita 233989-9 restores the correct retention and alignment of the guide washer and bit‑holder components.
