Description
Eaton TVS1320 & TVS1740 Gear Case Seal
The Eaton TVS gear case seal provides the correct replacement seal for compatible TVS1320 and TVS1740 superchargers. The seal sits between the gear case cover and rotor bearing plate and fits directly into the factory seal groove. Therefore, installing a fresh seal helps ensure proper sealing when servicing or repairing the gear case.
Additionally, we recommend installing a new seal whenever you remove the gear case cover. Reusing an old or damaged seal may result in improper sealing after reassembly.
