The National 711013 automatic transmission output shaft seal is engineered to provide reliable sealing performance for select Hyundai and Kia vehicles. Designed with a bi-directional lip helix type, this seal helps maintain transmission fluid integrity and prevent leaks in critical drivetrain components.

• Bi-directional lip design for effective sealing in both rotational directions
• Housing bore diameter of 2.913 inches (74.0 mm) ensures precise fitment
• Constructed from durable polyacrylate material for resistance to heat and wear
• Outside diameter measures 2.921 inches (74.2 mm) for secure installation
• Overall width with side lip is 0.669 inches (17.0 mm) for enhanced sealing surface
• Shaft diameter compatibility of 1.575 inches (40.0 mm)
• Part of the 711000 series, designed for consistent quality and fit

Detailed Product Description

The National 711013 output shaft seal is specifically designed for automatic transmissions in Hyundai and Kia models such as the Azera, Cadenza, Optima, Santa Fe, Santa Fe Sport, Santa Fe XL, Sedona, Sonata, Sorento, and Sportage. Its bi-directional lip helix design provides a reliable seal against transmission fluid leaks, accommodating rotational forces from both directions. Manufactured from polyacrylate, the seal offers durability and resistance to the high temperatures and chemical exposure typical in transmission environments. The precise housing bore and outside diameter measurements ensure a snug fit within the transmission housing, while the overall width with side lip enhances sealing effectiveness around the output shaft.

Common Applications and Problem Solving

• Prevents transmission fluid leaks from the output shaft area
• Reduces risk of contamination entering the transmission system
• Helps maintain proper transmission fluid pressure and performance
• Addresses wear-related seal failures in Hyundai and Kia automatic transmissions
• Mitigates issues related to shaft misalignment or vibration-induced leaks

Installation Notes and Tips

When installing the National 711013 output shaft seal, ensure the transmission housing bore is clean and free of debris. Proper lubrication of the seal lips with transmission fluid before installation can reduce initial wear and facilitate a smooth fit. Use appropriate tools to press the seal evenly into the housing bore without distortion. Verify shaft diameter compatibility (1.575 inches / 40 mm) to avoid improper sealing or premature failure.
