CAT 245-7339 Crankshaft Front Oil Seal
The CAT 245-7339 Crankshaft Front Oil Seal is a heavy-duty radial lip seal engineered specifically for Caterpillar engines. Designed to maintain critical oil pressure and prevent harmful fluid leaks, this genuine replacement part ensures your engine’s internal components remain protected from external dirt and contaminants. It comes equipped with a specialized red plastic installation sleeve designed to protect the seal lip during the mounting process. For proper function and longevity, the seal must be installed dry, and the red sleeve must be removed prior to pulley installation. Additionally, the crank rotation direction is clearly stamped directly on the seal body to guarantee accurate orientation during maintenance.
