FAG SS2809 Differential Pinion Seal - Rear

Overview of FAG SS2809 Differential Pinion Seal

The FAG SS2809 differential pinion seal is engineered to provide reliable sealing performance in driveline and axle applications. Designed with durable nitrile sealing material and a metal spring seal type, this part ensures effective protection against leaks and contamination.

• Seal Type: Metal with spring for consistent tension
• Sealing Material: Nitrile for resistance to oil and wear
• Bore Diameter: 2.75 inches (69.85 mm)
• Seal Outside Diameter: Approximately 2.75 inches (69.95 mm)
• Seal Width: 1.75 inches (7.95 mm)

Technical Details and Specifications

The FAG SS2809 differential pinion seal features a precise bore diameter of 2.75 inches (69.85 mm) and an outside diameter close to 2.75 inches (69.95 mm), ensuring a tight fit in compatible housings. The seal width of 1.75 inches (7.95 mm) provides adequate surface area for effective sealing. Constructed with nitrile sealing material, it offers resistance to oils, greases, and temperature variations commonly encountered in automotive differentials. The metal spring design maintains consistent radial force on the shaft, reducing the risk of leaks over time.

Applications and Problem Solving

• Prevents differential oil leaks in driveline assemblies
• Protects internal components from dirt and moisture ingress
• Reduces wear on pinion shafts by maintaining lubrication
• Helps maintain proper differential performance and longevity
• Addresses common seal failures due to aging or damage

Installation Notes and Tips

When installing the FAG SS2809 differential pinion seal, ensure the bore and shaft surfaces are clean and free of debris. Use appropriate tools to press the seal evenly into the housing without distortion. Verify the seal orientation matches the original part to maintain proper sealing function. Lubricate the sealing lip with compatible grease or oil before installation to reduce initial wear. Check for proper fitment with your specific vehicle make and model to avoid installation issues.
