6200 62CC Chainsaw Oil Drive Pump Worm Gear

Oil drive pump worm gear fits 6200 Chinese chainsaws with 62cc engines, including Komatsu Zenoah and Timberpro. The worm gear sits on the crankshaft and meshes with the oil pump rotor to maintain continuous bar and chain oil flow to the guide bar during cutting. The 6200 (62cc) is the largest of the common Chinese chainsaw engine classes and is typically used with longer guide bars under heavier cutting loads reliable chain lubrication is correspondingly more critical at this engine size. A stripped or worn worm gear disconnects the oil pump entirely while the engine continues to run normally, making oil starvation easy to miss until visible damage appears on the bar rails or drive links. Replacing the gear restores full oil pump drive without the need to replace the complete pump assembly.

Fits the following models:

• 6200 (62cc)
• Komatsu Zenoah
• Timberpro
