Makita 231574-2 Spare Part - TORSION SPRING 15 3600B
Original Makita torsion spring — part 231574-2 (listed as "TORSION SPRING 15") — a direct replacement spring used in Makita router assemblies such as the 3600B and 3612 series (3612BR / 3612C).
What it does: this tightly wound steel torsion spring provides the return/tension for the router’s lock/knob mechanism (the lever that holds and releases the base/height assembly), restoring correct tension and smooth locking action when the original spring has weakened or broken.
Details to note: Makita lists this part as “torsion spring 15” in exploded parts diagrams for the 3600B/3612 family — confirm the part number 231574-2 against your tool’s diagram to ensure fit. This genuine Makita component is a small, hardened-steel coil designed for the lever/post used on those router models.
