Original Makita compression spring — part 231240-1 — designed to restore correct return/tension action in compatible Makita tools.
Precision coil spring made from hardened spring steel for reliable fatigue resistance in repeated cycling; sold as a single replacement spring for the internal return/plunge/tension mechanisms.
Key dimensions (for fit checks): free length ≈ 13.6 mm, outer diameter ≈ 7.8 mm, wire diameter ≈ 0.7 mm. These compact dimensions suit router plunge and saw return assemblies and similar mechanisms.
Examples of Makita models that use part 231240-1 include (but are not limited to): RP0900 / RP0910 / RP1110C routers, RP1801 and RP2301FC routers, LS1013 / LS1016 / LS1016L / LS1214 / LS1216 mitre/circular saws and several vacuum/misc models referenced in Makita parts breakdowns. Use the model breakdown to confirm placement in your specific tool.
Simple to install where the original spring has lost tension, bent, or broken — a straightforward way to return smooth, predictable movement to the affected mechanism.
