Makita 322963-3 Spare Part - GUIDE PIN 2 HR4000C/4500C

Original Makita Guide Pin (part no. 322963-3) — a small but critical metal guide pin used in Makita SDS‑max rotary hammers to register and align internal components for reliable hammering action and smooth bit engagement.

This genuine Makita replacement is listed on the HR4500C parts breakdown (item 78) and appears in parts listings for the HR4000C/HR4500C family, so it’s the correct swap when the factory guide pin is worn, bent, or missing.

Common compatible models shown in parts catalogs include HR4000C and HR4500C (and related HR‑series rotary hammers that share the same parts layout). If your tool uses Makita part 322963‑3, this original Makita guide pin is sold as a single replacement item and drops into the guide assembly without modification.

Fits/compatibility references and parts diagrams are available in Makita parts lists and replacement‑parts catalogs if you need to confirm placement in your specific model.
