This seal is cataloged for the front output shaft position. Its body stays stationary in the transfer case housing while the sealing lip contacts the rotating output shaft. This helps retain lubricant and block contaminants.
- Rigid metal case: The body is made from deep drawn sheet steel to create a rigid, stress-resistant case.
- Garter spring: The garter springs use cold drawn steel wire to help with fluid retention.
- Correct fit: Built with a quality-tested design and materials for correct fit.
- Contaminant protection: Designed to protect against dirt and water.
SKF has developed seals since it invented the first integrated shaft seal in 1928, and it continues to pioneer new designs and bonding techniques. Its seals are made to specific designs using premium materials chosen for the application and its environment.
Signs this part may need replacing: lubricant seeping from the front output of the transfer case, wet residue around the front output, or a low transfer case fluid level. Diagnose the leak source before replacing.
