Transmission Seal

Transmission seals are used internally, but mostly externally on transmissions. Input shaft and output shaft  ride on bushings. The seals are used to keep the transmission fluid inside the transmission. They are also used in transfer cases as well as hydro drives.  Nothing worse that having a leaking hydro drive, oil contamination in the ecosystem. BAD BAD NEWS. That’s why it’s imperative to have good quality seals that don’t leak. The fluid needs to be retained within the unit. Contamination are the major reason for seal failure, Contaminants in the fluid cause premature bushing failure which in results in the center of shaft to not be in the center of the seals. It allows oil to pass by the seal.

Seal design plays an important role in long service life. Improvements in design allows for capability to handle significant amount of run out and misalignments. Due to their exposure beneath vehicles, axle seals are subject to  harsh conditions, including rocks and dirt contamination.  Contamination exclusion under such conditions is the key to long life.
