AGCO - X548960666000 - O-Ring Of Drive Filter Massey Ferguson

This O-ring seals the drive filter housing at the valve block, preventing fluid bypass between the filter element and the block's internal passages. It sits in the groove machined into the valve block face, where compression against the filter cap creates the seal. A degraded or nicked O-ring allows unfiltered fluid to bypass the element, which can introduce contaminants into the downstream hydraulic circuits. As an original AGCO component, the O-ring is molded to the same cross-section and durometer as the original seal, so it seats fully in the groove without requiring additional sealant or shimming. Replace the O-ring whenever the filter element is changed; lubricate it lightly with clean hydraulic fluid before installation to prevent rolling or pinching during cap tightening.
