The MS390 oil pump assembly is a core lubrication part for MS390 high-load chainsaws. Its heavy-duty cast aluminum body resists deformation and vibration from intense logging, while the copper-core internal structure enhances wear resistance (suited for long-term high-frequency oil delivery).

Designed to match MS390's lubrication system, the assembly installs seamlessly. Its optimized gear mechanism maintains consistent oil pressure—adapting to heavy wood cutting and prolonged operation, preventing dry friction between bar and chain, and extending their service life.
