Makita 256437-1 Spare Part - PIN 4 9520NB/9522NB/9526PB

Original Makita Pin (Part No. 256437-1) — Pin 4

Restore proper alignment in your Makita tool with this original Makita locating pin (Part 256437-1, shown as "Pin 4" on Makita diagrams). It’s a small, hardened steel dowel-style pin used to locate and retain mating components inside the motor/gear/collet assemblies so shafts and gears run true and bearings aren’t stressed. The pin installs into a precision bore and is designed to match the original fit and finish for quiet, vibration-free operation.

Fits (example models)

Common applications include Makita compact routers/trim routers and several 115–125 mm angle grinders. Examples shown on Makita parts diagrams and listings include: RT0700C / RT0702C (trim/edge routers), DRT50 series, RP1110C / RP1111C / RP0910 (routers), and angle grinders from the 952x/95xx family such as 9520NB, 9521NB, 9522NB, 9523NB, 9524NB, 9526PB, 9527NB/PB, 9528NB/PB. Check your tool’s parts diagram — this is the part labeled "Pin 4" or 256437-1.

Quick notes for use

- Replace this pin if it’s bent, worn, or missing; a loose or damaged pin commonly causes misalignment, vibration, or premature wear of adjacent gears/bearings.

- It’s a pressed/locating fit — remove and install with simple hand tools or a small arbor press if needed; no modification required.

If your parts diagram lists 256437-1 or shows "Pin 4" in the area described above, this original Makita pin is the direct replacement to restore correct assembly and operation.
