Keep lubricant in and road grime out with the SKF Power Steering Pump Shaft Seal / Transfer Case Shift Shaft Seal 7440. SKF lists this seal for Chevrolet, Ford, Dodge and GMC vehicles, and the fitment also covers International, Mercury, Plymouth, Studebaker and other classic makes. Applications include the 1953-1957 Plymouth Belvedere, 1954-1972 Ford F-250, 1955-1959 Ford Thunderbird, 1960-1965 GMC 1500 Series and 1980 Chevrolet C60. See the "Vehicles it fits" section for the full list and engine details.
SKF 7440 is cataloged under both part names. Like any shaft seal, its case stays stationary while the sealing lip contacts the moving shaft. This helps hold fluid in and keep contaminants out.
- Seal heritage: SKF introduced the first integrated shaft seal in 1928. The company has continued to develop new seal designs and bonding techniques since then.
- Tested design and materials: Built with a high-quality, tested design and materials for correct fit.
- Rigid metal case: The body is formed from deep drawn sheet steel, creating a rigid, stress-resistant case.
- Steel garter spring: The garter spring is made from cold drawn steel wire for fluid retention.
- Dirt and water protection: Designed to guard against dirt and water.
Signs this seal may need replacing include fluid seeping at the power steering pump shaft or around the transfer case shift shaft, and a fluid level that keeps dropping. Diagnose the leak source before replacing, because nearby gaskets, hoses or fittings can also leak.

Frequently Asked Questions
Why is this listed as both a power steering pump shaft seal and a transfer case shift shaft seal?
SKF 7440 is cataloged under both names. Depending on the vehicle, it is used at the power steering pump shaft or the transfer case shift shaft. The "Vehicles it fits" section lists each application.
What is the seal's case made of?
The body is deep drawn sheet steel, which forms a rigid, stress-resistant metal case. The garter spring uses cold drawn steel wire.
Does the seal rotate with the shaft?
No. The seal stays stationary while its lip contacts the moving shaft, helping keep lubricant in and dirt and water out.
Which vehicles does SKF 7440 fit?
Applications include the 1954-1972 Ford F-250, 1955-1959 Ford Thunderbird and 1960-1965 GMC 1500 Series, plus many more classic cars and trucks. See the "Vehicles it fits" section for the full list.
What are signs this seal may need replacing?
Fluid seeping at the pump shaft or shift shaft, or a fluid level that keeps dropping, may indicate a worn seal. Confirm the leak source first, since other components can leak too.
