AGCO - F716201510170 - Engine O-Ring Fendt

This engine o-ring seals the interface between the engine block and a mating component, preventing oil or coolant leakage at the joint. It sits in a machined groove on the engine assembly, where its cross-section compresses to create a static seal under operating pressure and temperature. A degraded o-ring allows fluid to seep past the sealing face, which can lead to gradual loss of lubricant or coolant and eventual overheating or component damage. The original AGCO part is molded to the same cross-sectional profile and hardness as the factory seal, so it seats correctly in the groove without requiring additional sealant or shimming. On installation, ensure the groove is clean and dry, and lubricate the o-ring lightly with engine oil before seating.
