Wholesale only · Full payment before shipment · Send your machine nameplate to confirm fitment
Description
The crankshaft seal is used to retain engine oil and prevent external contaminants from entering the engine oil system.
Seals for dry applications (air-to-oil interface) typically include a primary sealing lip that prevents engine oil leakage and a dust lip. In wet applications (oil-to-oil interface), the dust lip is replaced with an auxiliary lip that can pump external fluid away from the engine. Some seals have a plastic sleeve to assist with the installation process.
