366-6004: 186.33mm Outer Diameter Crankshaft Seal

Description: 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.
