• Seal wear from age, heat, and normal drivetrain use
• Service replacement for a damaged or hardened transmission seal

Installation Notes and Tips

Verify the shaft diameter, outside diameter, and width before installation to confirm the seal matches the transmission housing and shaft dimensions. Inspect the shaft surface for grooves, corrosion, or burrs that could affect sealing performance. Clean the sealing area thoroughly and install the seal squarely to avoid distortion during service.
