The MS660 oil pump assembly is a core lubrication part for MS660 heavy-duty high-power chainsaws. Its high-power dedicated cast aluminum body withstands extreme vibration and load from professional logging, while the dual-seal design (oil seal + structural gasket) eliminates leakage risks.

Engineered for MS660's high-output system, the assembly's gear mechanism delivers high-volume, stable oil flow—matching the chainsaw's fast cutting speed and heavy wood processing needs. It ensures the bar and chain stay fully lubricated, preventing overheating and reducing wear in intensive operation.
