Makita 345739-1 — Spacer (genuine Makita)
Keep your Makita metal cutter running true with this original Makita spacer, part number 345739-1. This precision spacer is fitted on the spindle/flange assembly to maintain correct spacing and alignment between the spindle, inner/outer flanges and blade housing — an often‑overlooked component that prevents wobble and ensures clean, safe cuts. Genuine Makita part; sold as a single spacer.
Key details
- Description on Makita parts breakdowns: "Spacer" — positioned near the spindle, inner/outer flange and retaining ring.
- Sold: single unit; check your model’s parts breakdown because the same spacer part number can appear multiple times for a model.
Example models this spacer fits (examples from Makita parts lists and service sheets)
- BCS550 series (BCS550 / BCS550RFE).
- DCS550 series (DCS550, DCS550RMJ, DCS550Z).
- DCS551 / DCS551RMJ / DCS551ZJ (150 mm metal cutters).
- DCS552 (136 mm cordless metal cutter) and DCS553 (150 mm variants) — listed in Makita parts files.
Why this part matters
- Restores the correct axial spacing on the spindle/flange assembly so flanges and blade run concentrically, reducing vibration and premature wear.
If you’re replacing a worn or missing spacer on one of the listed Makita metal cutters or saws, this is the original Makita spacer specified in the service parts lists for those models.
