Description
Overview:
The Worm Gear for Hikoki CS33 series chainsaws is a genuine OEM component that drives the automatic bar and chain oil pump. Made from a hard‑wearing polymer (nylon) selected by Hikoki for low friction and long service life, this worm gear transfers rotation from the clutch area to the oil pump so your chain stays correctly lubricated during cutting. Correct lubrication reduces heat, wear, and bar/chain damage. This Genuine Hikoki part ensures the exact tooth profile and fit demanded by the CS33 platform for reliable performance. Suitable for compact petrol chainsaws such as the CS33EB and CS33EDTP, it is an ideal like‑for‑like replacement when your saw shows symptoms such as a dry chain, inconsistent oil feed, or a stripped/worn drive gear. Genuine Hikoki OEM part, number 6685330.
