436-1479: Seal-crankshaft

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: • For counter clockwise rotation crankshafts • Material: Plastic (Polytetrafluoroethylene)(PTFE) • Air-to-fluid interface • Shaft diameter: 230 mm (9.05 in) • Bore diameter: 272 mm (10.74 in) • Outside diameter: 272.33 mm (10.72 in) • 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.
