The Twin Power TWP043288 main drive gear seal is a direct-fit replacement for Harley-Davidson part 12076A. It seals the transmission output gear to help prevent oil leaks in Evolution and Twin Cam 5-speed Big Twin transmissions used on 1994–2006 models. This seal is designed for reliable performance during transmission maintenance, drivetrain service, or replacement of the front pulley or sprocket.

• Designed for Evolution and Twin Cam 5-speed Big Twin transmissions through 2006


• Helps seal the transmission output gear and reduce the risk of oil leakage

• Direct-fit replacement for Harley-Davidson 12076A


• Made in the USA

The Twin Power TWP043288 seal fits a broad range of Harley-Davidson Big Twin motorcycles, including Softail, Touring, and related applications. It fits select 2001 Softail models such as the Fat Boy, Heritage Springer, Night Train, Softail Deuce, Softail Standard, and Springer Softail, as well as select 2002 Touring models including the Road King Classic, Electra Glide Classic, and Electra Glide Ultra Classic. Verify the motorcycle application before installation, as this seal does not fit the 2006 Dyna FXD.
Built as a practical replacement component, the Twin Power main drive gear seal supports proper transmission sealing and helps maintain a clean drivetrain. Installing a new seal during related pulley, sprocket, or transmission work can help avoid reusing a worn sealing surface and reduce the possibility of continued fluid loss. Always follow the motorcycle manufacturer’s service procedures for removal, inspection, and installation.
