231687-9 supersedes older part numbers: 231662-5

Makita 231687-9 — Torsion Spring 17 (genuine Makita)

Description:

A small, precision torsion spring used in the blade-clamp/slider assembly of Makita reciprocating saws. It provides the return/preload force that holds the blade clamp and slider in the correct position so the blade seats and releases reliably. The spring is sold as Makita part no. 231687-9 (listed as "Torsion Spring 17") and is sold as a single item

Fit / example models:

Common Makita models that use this spring include JR3050T / JR3050TX, JR3070CT (and JR3070CTZ), BJR181 / BJR182, and several DJR-series cordless reciprocating saws (DJR181, DJR182, DJR186, DJR187)

Key details:

- Makita part number: 231687-9; designation: Torsion Spring 17.

- Function: torsion-type coil that assembles to the slider/blade clamp to provide preload/return force.

- Construction: supplied as the original Makita spring, manufactured to the tool’s specification from high‑tensile spring steel for reliable spring action and long service life.

- Packaging/quantity: listed in Makita parts lists as a single spring (qty 1) for the referenced models.

Why this part:

If your reciprocating saw’s blade clamp is loose, won’t hold blades, or the clamp hardware has lost its tension, replacing the Makita 231687-9 restores the intended clamp preload and lets the tool accept and release blades correctly. The part is a direct match to Makita’s "Torsion Spring 17" specification used in the models above.

Note: Install per the tool’s service diagram so the spring seats correctly on the slider/clamp.
