Original Makita part 234264-6 — Compression Spring 3. This small, purpose-made compression spring is listed in Makita service diagrams as "Compression Spring 3" and is specified at about 3 × 28 mm (clearance / coil dimension commonly shown as 3x28 mm in parts breakdowns).
Use & fit: this spring sits in the change‑lever / lock‑button area on a number of Makita rotary and combination hammers. It is used across many Makita models — examples include DHR242, DHR243, BHR242, BHR243 and combination hammers such as HR007G and HR010G amongst others listed in Makita parts diagrams. If your tool’s change lever or lock button feels loose, sticky, or fails to return, replacing this original Makita spring restores the proper tension and engagement.
What you get: one genuine Makita compression spring (part no. 234264-6), ready to drop into the spring seat shown in the Makita exploded drawings — a compact, direct replacement designed to the tool maker’s specification.
