What This Seal Helps Address

• Transmission fluid seepage at the output shaft
• Oil residue around the rear of the transmission case
• Seal wear from age, heat, and shaft movement
• Loss of sealing integrity in manual gearbox service
• Contamination entering the transmission area through a worn seal

Installation Notes and Quality

Verify shaft diameter, housing bore, and transmission code before installation. The seal measures 35.000 mm inside diameter, 48.200 mm outside diameter, and 12.000 mm width, so matching the transmission case and shaft dimensions is important for proper seating. National has supplied sealing solutions for more than 75 years and continues to develop designs for modern vehicle service needs. National 710818 is part of the 710800 series and is engineered as an oil seal for manual transmission output shaft applications.
