• Seal Type: Metal construction with spring, auxiliary lip, and inner shell for enhanced sealing
• Sealing Material: High-quality nitrile for resistance to oil and wear
• Bore Diameter: 3.5 inches (88.9 mm) ensuring proper fitment
• Seal Outside Diameter: Approximately 3.505 inches (89.027 mm) for secure installation
• Seal Width: 2.5 inches (63.5 mm) providing robust sealing surface

Technical Details and Specifications

The SS3238 PTO output shaft seal from FAG is constructed with a metal outer shell combined with a spring-loaded auxiliary lip and inner shell design. This configuration ensures consistent contact pressure and effective sealing under varying operating conditions. The nitrile sealing material offers excellent resistance to petroleum-based fluids and mechanical wear, making it suitable for heavy-duty automotive driveline applications. With a bore diameter of 3.5 inches and an outside diameter close to 3.505 inches, this seal fits precisely in compatible PTO output shafts, minimizing the risk of leaks and contamination.

Applications and Problem Solving

• Prevents oil leaks in PTO output shafts of commercial trucks and heavy machinery
• Protects driveline components from dirt and debris ingress
• Reduces wear on shaft surfaces by maintaining proper lubrication
• Helps maintain hydraulic system pressure by ensuring a tight seal
• Addresses common seal failure issues such as lip deformation and material degradation

Installation Notes and Tips

Ensure the PTO output shaft and housing are clean and free of debris before installation. Verify the bore and outside diameters match the SS3238 specifications to guarantee proper fitment. Use appropriate tools to press the seal evenly into place without damaging the sealing lips or metal shell. Avoid excessive force during installation to maintain the integrity of the nitrile sealing material and spring components.
