Makita 231633-2 — genuine Makita torsion spring (part 231633-2). This small but critical torsion spring is used in the blade‑guard / lock pivot of Makita compound/mitre saws and is listed as "Torsion Spring 8" in Makita parts drawings (supplied as a single spring).
Fits (examples): LS1040 / LS1040F, LS1013 / LS1013L, LS1016, LS1214, LS1216 and LS1216L slide/compound saw variants — these service diagrams show 231633-2 as the designated torsion spring for those models.
Key details: designed to seat on an 8 mm rod (listed alongside "Rod 8" in the service drawing), so it matches the factory pivot shaft and restores the correct return/tension for the guard/lock assembly. Supplied as the single torsion spring part number 231633-2 used in the saw’s mechanism.
If you need a reliable replacement that fits without modification, choose this original Makita torsion spring — it’s the exact replacement called out in Makita parts lists and is one of the common Makita spare parts used to fix guard/lever return issues on the models listed.
