Genuine Makita Ring Spring 15 — part number 233992-0 — a precision-formed metal ring spring (15 mm) used in Makita rotary/combination hammer assemblies.
The spring seats between the flat washer and the adjacent washer inside the hammer mechanism to preserve correct preload and spacing; it’s sold individually and installs quickly during a routine hammer head service.
Fits many Makita SDS-style rotary/combination hammers — for example HR3011FC, DHR283, HR2663 and HR2611F and a number of HR/DHR series models — and is the exact part shown on Makita parts diagrams for those tools.
Compact, durable and ready to restore correct operation, this genuine Makita ring spring is a straightforward replacement when servicing or repairing your tool — a small but important item among parts for power tools.
