Technical Details of FAG SS2599 Differential Pinion Seal

The FAG SS2599 differential pinion seal is designed with a metal outer casing that provides structural strength and resistance to deformation. The sealing lip is made from Viton, a fluorocarbon elastomer known for its excellent resistance to high temperatures, oils, and other automotive fluids. This ensures a reliable seal around the pinion shaft, preventing leaks and contamination. The bore diameter measures 80.264 mm (3.16 inches), while the outside diameter is 80.391 mm (3.165 inches), ensuring a precise fit within the differential housing. The seal width is available in 1.552 inches (13.868 mm), providing adequate surface area for sealing without excess friction.

Compatible Vehicles and Applications

This differential pinion seal is compatible with the following Ford models:

• Ford Excursion
• Ford F-350 Super Duty

It is specifically designed to maintain the integrity of the driveline by sealing the pinion shaft in the differential assembly, preventing oil leaks and ingress of dirt or debris.

Common Issues Addressed by the FAG SS2599 Seal

• Prevents differential oil leaks that can cause driveline damage
• Reduces contamination from dirt and moisture entering the differential
• Maintains proper lubrication by sealing the pinion shaft
• Minimizes wear on differential components due to fluid loss
• Helps avoid costly repairs related to seal failure

Installation Notes and Tips

When installing the FAG SS2599 differential pinion seal, ensure the differential housing and pinion shaft are clean and free of debris. Use appropriate tools to press the seal evenly into place without damaging the sealing lip. Verify the seal orientation matches manufacturer specifications to maintain optimal sealing performance. It is recommended to inspect related components such as bearings and gears during installation for any signs of wear.
