Detailed Product Description

The National 710902 transfer case output shaft seal is designed to meet the demanding requirements of Dodge Ram trucks, including the Ram 1500, 2500, and 3500 series. This oil seal features a fluoro-elastomer sealing material known for its resistance to heat, oil, and wear, making it suitable for harsh automotive environments. The counter-clockwise spiral lip design enhances sealing efficiency by directing contaminants away from the shaft, reducing the risk of leaks and premature wear.

With an inside diameter of 2.300 inches (58.420 mm), this seal fits snugly around the transfer case output shaft, while the outside diameter of 3.330 inches (84.579 mm) and flanged outside diameter of 3.858 inches (98.000 mm) ensure a secure fit within the housing bore. The thickness of 0.425 inches (10.795 mm) and overall width with side lip of 1.969 inches (50.000 mm) provide the necessary durability and sealing surface area to maintain transfer case fluid containment.

Common Applications and Problem Solving

  • Prevents transfer case fluid leaks in Dodge Ram 1500, 2500, and 3500 trucks
  • Reduces contamination ingress that can cause transfer case damage
  • Addresses wear-related seal failures due to heat and friction
  • Helps maintain proper lubrication and transfer case performance
  • Replaces worn or damaged output shaft seals to restore vehicle reliability

Installation Notes and Tips

  • Ensure the transfer case output shaft and housing bore are clean and free of debris before installation
  • Use appropriate tools to avoid damaging the fluoro-elastomer seal during installation
  • Verify the seal orientation matches the counter-clockwise spiral lip design for optimal sealing
  • Check for proper fit by confirming inside and outside diameters align with vehicle specifications
  • Consult vehicle service manual for torque specifications and installation procedures

Quality Assurance and Warranty

National transfer case output shaft seals are manufactured to meet industry standards for durability and performance. The 710902 seal is made from high-quality fluoro-elastomer material to withstand exposure to heat, oil, and mechanical stress. While specific warranty details may vary, National typically offers coverage against manufacturing defects to ensure customer confidence in product reliability.
