Common Problems This Seal Can Address

• Transmission fluid leakage at the oil pump seal area
• Contamination entry from dirt, dust, or moisture at the seal interface
• Loss of transmission fluid through a worn or hardened seal
• Seal wear caused by age, heat, or fluid exposure
• Improper sealing after transmission service when the original seal is no longer effective

Installation Notes and Tips

Verify the bore diameter, outside diameter, and seal width against the removed part before installation. Clean the sealing surface thoroughly and inspect the pump bore for scoring, corrosion, or debris that could affect sealing. Confirm the vehicle application by year, make, model, and position before ordering, especially on Hyundai Accent, Kia Rio, and Mitsubishi Galant fitments. Proper alignment during installation helps prevent lip damage and premature leakage.

Quality Assurance

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