Original Makita 233979-2 — Ring Spring 28: a genuine Makita replacement ring spring engineered for selected Makita rotary/combination hammer drills. This precision-formed ring spring is made from high‑tensile spring steel to resist fatigue and keep internal components correctly preloaded, restoring consistent hammer action and prolonging tool life when the original spring wears.

Direct-fit part number 233979-2 (sold individually) fits a range of Makita models including BHR242, BHR243, DHR242/DHR243 series and several HR/DHR/HR‑series rotary hammers — ideal for routine servicing or on-site repairs to bring performance back to factory specification.

Easy to install during normal maintenance (follow your service manual), this original Makita ring spring provides the exact form, fit and spring tension the manufacturer intended — a small part that makes a big difference in hammer stability and reliability.
