Detailed Product Description

The Timken 100552 differential pinion seal is manufactured using V-fluoro-elastomer, a material known for its resistance to heat, oil, and other automotive fluids. This ensures long-lasting performance in demanding driveline environments. The seal’s precise dimensions, including an outside diameter of 2.872 inches and a shaft diameter of 1.844 inches, provide a secure fit to prevent fluid leakage around the pinion shaft. The housing bore diameter of 2.865 inches and a width of 0.425 inches allow for proper seating within the differential housing. The clockwise helix type design aligns with the rotational direction of the pinion shaft, maintaining effective sealing under operational stresses.

Compatible Vehicles and Applications

• Compatible with Ford models such as Edge, Escape, Explorer, Flex, Fusion, Taurus, and Taurus X
• Fits Lincoln vehicles including Continental, MKS, MKT, MKX, MKZ, and Milan
• Suitable for Mazda Tribute and Mercury Mariner and Sable
• Designed specifically for differential pinion sealing in these makes and models
• Addresses common issues like oil leaks, contamination ingress, and seal wear in the driveline

Installation Notes and Tips

Ensure the differential housing bore and pinion shaft are clean and free of debris before installation. Verify the helix direction matches the pinion shaft rotation (clockwise for this seal). Use appropriate tools to press the seal evenly into the housing bore without distortion. Avoid damaging the sealing lip during installation to maintain optimal performance.
