Replacement Oil Pump Assembly for Husqvarna 40 & 45 Chainsaws

Restore proper chain lubrication and prevent costly bar and chain friction damage with this premium replacement oil pump assembly. Engineered as a direct replacement for original part number 506027701, it delivers a precise, consistent flow of bar oil directly to the cutting channel during high-RPM cutting tasks.

Specifically designed for Husqvarna 40 and 45 series chainsaws, this high-durability oil pump resists mechanical wear and thermal expansion under heavy daily use. Installing a fresh oil pump ensures smooth cutting action, prevents chain overheating and snapping, and extends the operational lifespan of your saw's cutting attachments.
