Genuine Makita disc spacer / washer — part no. 900004375 — designed to sit between starter/clutch components on select Makita petrol chainsaws. It’s a compact, flat stamped-steel spacer (disc-shaped washer) that keeps the starter/flywheel and clutch assemblies correctly spaced and running true, preventing rubbing and premature wear.
Fits a range of Makita/Dolmar chainsaw models including DCS330S (16"), DCS340, DCS390, DCS400 and closely related PS/DCS series like DCS401 and DCS410
Supplied as the single replacement disc spacer, this original Makita part is ideal when the washer is bent, worn or missing and you need a straightforward repair to restore correct starter/clutch operation. Keep it on hand with other small parts for power tools that commonly wear in routine service.
(If your tool’s parts diagram lists a different part number for the same area, cross‑check that diagram before installing.)
