Detailed Description

National 710705 is an oil seal in the 710700 series designed for automatic transmission output shaft service. The seal measures 57.000 mm inside diameter, 72.200 mm outside diameter, and 8.500 mm width, with a 72.000 mm housing bore specification. Its bi-directional lip design supports consistent sealing at the output shaft interface, while the polyacrylate material is suited to transmission fluid exposure and temperature demands found in modern drivetrains.

This part fits a range of Ford, Lincoln, Mazda, and Mercury vehicles equipped with the Ford 6F35 transmission, including Ford Escape, Ford Fusion, Ford Edge, Lincoln MKC, Lincoln MKX, Lincoln MKZ, Mazda Tribute, Mercury Mariner, and Mercury Milan. Use National 710705 when replacing a worn output shaft seal on the right side of the transmission.

What This Part Helps Address

• Transmission fluid seepage at the output shaft seal
• Fluid loss around the right-side transmission housing
• Seal wear from age, heat, and drivetrain movement
• Leak-related drivability concerns tied to low transmission fluid
• Service replacement for Ford 6F35 transmission applications

Installation Notes and Tips

Confirm shaft diameter, housing bore, and transmission application before installation. Inspect the sealing surface for scoring or contamination, and clean the bore thoroughly before pressing the seal into place. For best results, verify the vehicle uses the Ford 6F35 transmission and match the right-side position listed in the fitment data.

Quality Assurance

National has supplied sealing solutions for more than 75 years and continues to develop sealing components for current vehicle platforms. Part number 710705 is engineered to meet the dimensional and material requirements of the listed applications.
