190-2463: Crankshaft Seal

Crankshaft seals retain engine oil and prevent external contamination from entering the engine oil system. Seals designed for dry applications (air-to-fluid interface) typically include a primary lip that prevents engine oil from leaking, and a dust lip. In wet applications (fluid-to-fluid interface), the dust lip is replaced by an auxiliary lip capable of pumping external fluid away from the engine. Some seals have a plastic sleeve to aid in the installation process. Attributes: • Air-to-fluid interface • Cat crankshaft seals are precisely designed to perform in this very demanding application. They must be able to withstand high rotational speeds, elevated temperatures, and high frequency axial motion. • Cat sealing system uses a robust design, testing, and validation process.
