Detailed Description
This differential pinion seal is engineered to retain gear oil at the pinion area while keeping contaminants out of the housing. Timken 100552 uses a reinforced outer case and a ribbed inner diameter to improve sealing contact and installation stability, while vent holes help manage heat around the seal lip during operation. It cross-references National 100552 and Davico Mfg 18442 for the same application.

What It Is Used For
- Rear differential oil seepage at the pinion seal area
- Contamination entering the differential housing
- Heat-related seal wear around the pinion lip
- Seal leakage caused by minor shaft or spindle surface imperfections
- Loss of lubricant that can affect driveline operation
Installation Notes and Tips
Verify shaft diameter, housing bore, width, and helix direction before installation. Clean the sealing surface and inspect the pinion area for wear, scoring, or debris that could affect seal seating. For best results, install the seal squarely to avoid case distortion and confirm the rear differential application matches the vehicle and axle configuration.
Quality Assurance
Timken oil and grease seals are built with precision sealing designs focused on lubricant retention and contamination control. The reinforced case, contamination exclusion features, and heat-management venting reflect the brandβs driveline sealing engineering approach.
