What It Helps Address

• Transmission oil leakage at the pump seal area
• Fluid loss that can affect transmission operation
• Contamination entry around the pump sealing surface
• Wear-related sealing issues during transmission service
• Replacement needs on front-position transmission pump seal applications

Installation Notes and Tips

Verify bore diameter, outside diameter, and seal width before installation to confirm the seal matches the transmission pump housing. Inspect the pump surface for scoring, corrosion, or debris before fitting the new seal, and clean the sealing area thoroughly. Use proper installation tools to keep the seal square during assembly and avoid damaging the nitrile lip or spring element. Confirm the vehicle application by year, make, model, and front position before service.

Quality Assurance

FAG designs seals to meet vehicle manufacturer specifications and works with suppliers to maintain its quality standards. The seal construction is intended to protect critical end components from contamination and help retain lubricant over the service life of the bearing or sealed assembly.
