Keep lubricant where it belongs and dirt and water out with the SKF Manual Transmission Seal / Differential Pinion Seal, part number 13739. This rear-position seal is a direct-fit replacement for many vehicles, among them the 1974-1978 Ford Mustang II, 1949-1953 Studebaker 2R10 and 1949-1953 Studebaker 2R11; see the Buyer's Guide tab for the full list. It is listed under both names: manual transmission seal and differential pinion seal.

  • Tested design and materials: Built with a high-quality, tested design and materials for correct fit.
  • Dirt and water protection: Designed to provide superior protection against dirt and water.
  • Garter spring: Uses cold drawn steel wire for superior fluid retention.
  • Rigid metal case: The body is formed from deep drawn sheet steel to create a rigid, stress-resistant metal case.

SKF has been a leader in seal design and development 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 from premium materials. Those materials are chosen to suit both the application and its operating environment, with the aim of keeping lubricants in and contaminants out.

The seal body stays stationary in its bore while its lip rides on the rotating shaft. Signs this seal may need replacing include lubricant seeping or dripping at the rear seal area, an oily film on the surrounding housing, or a falling lubricant level. Diagnose the source of any leak before replacing parts.
