Technical Details and Material Specifications

The SKF 19310 differential pinion seal features a polyacrylate sealing surface, which offers reliable resistance against oil degradation and mechanical wear. Its precise dimensions—0.313 inch width, 2.888 inch outside diameter, and 1.938 inch shaft diameter—ensure a secure fit within the differential assembly. This seal is designed to maintain optimal sealing pressure around the pinion shaft, preventing fluid leaks and contamination ingress that could compromise driveline performance.

Compatible Vehicles and Applications

This differential pinion seal is compatible with several classic and late-model vehicles, specifically Oldsmobile 98 and Pontiac models including Bonneville, Catalina, and Grand Prix. It is intended for use in the driveline and axle assemblies where maintaining a tight seal around the pinion shaft is critical for proper differential operation.

• Prevents differential fluid leaks
• Reduces risk of contamination entering the differential
• Maintains driveline lubrication integrity
• Helps avoid premature wear of differential components
• Supports smooth and reliable differential function

Installation Notes and Tips

When installing the SKF 19310 differential pinion seal, ensure the mating surfaces are clean and free of debris. Use appropriate tools to press the seal evenly into the housing without distortion. Verify the shaft diameter matches the seal’s 1.938 inch specification to avoid leaks. Proper lubrication of the seal lip before installation can extend service life and improve sealing performance.
