Product Description
Cometic Transmission Mainshaft Seal for Harley-Davidson
Replace a worn or leaking transmission mainshaft seal with the Cometic C9359 Mainshaft Seal. Designed as a direct replacement for Harley-Davidson OEM #12050, this seal helps prevent transmission oil from leaking around the mainshaft on compatible Harley-Davidson Big Twin and Sportster models.
Cometic manufactures the C9359 from high-quality Viton sealing material for dependable resistance to oil, fuel, heat and the harsh operating conditions found inside a motorcycle drivetrain. The durable material is designed to resist cracking, hardening and deterioration over time while maintaining a reliable seal around the transmission mainshaft.
The mainshaft seal is an important service component whenever the transmission pulley, sprocket, primary drive or related components are removed. Replacing an aged or damaged seal during transmission or drivetrain service can help prevent future leaks and reduce the need to disassemble the area again.
