The MS661 oil pump component is a high-performance lubrication part for MS661 professional chainsaws. Its precision cast aluminum body (with optimized structural rigidity) resists the extreme vibration of high-RPM operation, while the copper-bushing valve core enhances wear resistance and oil flow control precision.

Designed for MS661’s high-efficiency system, the split-type component (pump body + valve core) allows targeted replacement. Its micro-adjustable oil pressure mechanism matches the chainsaw’s variable load (from fast trimming to heavy log cutting), ensuring consistent lubrication without excess oil waste.
