Original Makita compression spring — part no. 234347-2 (listed as "Compression Spring 11") — a direct replacement spring used inside the trigger/impact assembly of Makita soft-impact / cordless impact drivers. It restores the return force and positive action of the internal mechanism so the tool behaves like new.
Fits (examples) shown in Makita parts diagrams and parts listings: DTS131 / DTS141. Use these model references to confirm it matches the spring called out in your tool’s parts diagram.
Supplied as the single genuine Makita replacement spring called out in Makita parts lists — install where the original compression spring is required to restore correct trigger/hammer return and consistent operation. "If you are rebuilding a loose or broken impact chuck, this spring is usually replaced alongside the Chuck Sleeve (143294-5 / 143299-5) and the Steel Ball 3.5 (216019-1). Changing these low-cost parts at the same time completely restores your quick-release chuck to factory condition."
