Technical Details and Specifications

The SKF 18922 differential pinion seal features a nitrile sealing surface, which offers durability and resistance to heat and automotive fluids. With a width of 0.484 inches and an outside diameter of 3.254 inches, this seal fits precisely around a 1.875-inch shaft diameter. These dimensions ensure a secure seal within the differential assembly, reducing the risk of leaks and contamination. The use of nitrile material provides a balance of flexibility and toughness, suitable for the demanding conditions found in Cadillac DeVille, Fleetwood, and Ford F-250 and F-350 differentials.

Applications and Problem Solving

This differential pinion seal is designed for use in the driveline and axle systems of specific vehicles. It addresses common issues such as:

• Preventing differential fluid leaks that can lead to component damage
• Reducing contamination from dirt and debris entering the differential
• Maintaining proper lubrication within the differential assembly
• Minimizing wear on the pinion shaft and bearings
• Ensuring consistent differential performance under various driving conditions

Installation Notes and Tips

When installing the SKF 18922 differential pinion seal, ensure the mating surfaces are clean and free of debris. Proper alignment on the 1.875-inch shaft diameter is critical to avoid premature wear or leaks. Use appropriate tools to press the seal evenly into place without distortion. Verify the seal’s nitrile surface is not damaged during installation to maintain its sealing integrity. It is recommended to inspect the differential housing and pinion shaft for wear or damage before installation.
