This oil filter housing gasket seals the joint between the filter housing and the oil cooler assembly. It prevents oil leakage at the interface, maintaining system pressure and ensuring that all oil passes through the filter element. A compromised gasket allows oil to bypass the filter or escape externally, which can lead to pressure loss and inadequate lubrication of downstream components. The gasket is manufactured by AGCO to match the original seal groove geometry, ensuring proper compression and sealing when the housing is torqued to specification. Replace the gasket whenever the filter housing is removed for service.
