This timing cover gasket seals the joint between the engine block and the timing cover, preventing oil leaks and keeping contaminants out of the timing drive assembly. It is a single-use component that must be replaced whenever the timing cover is removed during engine service or overhaul. A failed gasket allows oil to weep past the cover, which can lead to low oil pressure at the front of the engine and accelerated wear on the timing chain or gears. The gasket is manufactured by AGCO to match the original sealing surface profile of the housing, ensuring proper compression when the cover bolts are torqued to specification. On reinstallation, clean both mating surfaces thoroughly and apply the recommended sealant to the gasket corners if specified by the engine service manual.
