Detailed Product Description

The National 222030 input shaft seal is part of the 220000 series, designed specifically for manual transmission applications requiring precise sealing solutions. Made from nitrile, this seal offers excellent resistance to petroleum-based fluids and mechanical wear, which is critical for maintaining transmission integrity. The seal’s dimensions—0.787 inch inside diameter and 1.387 inch outside diameter—match the shaft and housing bore sizes commonly found in models such as the Audi 924, Chevrolet Quantum, and Suzuki Swift. The 7 mm thickness provides a robust barrier against oil leaks, while the clockwise-spiral lip design enhances sealing efficiency by directing fluid back into the transmission and preventing external contaminants from entering.

Applications and Problem Solving

• Prevents oil leaks from manual transmission input shafts
• Reduces contamination ingress that can cause premature transmission wear
• Maintains proper lubrication within the transmission system
• Helps avoid costly transmission repairs due to seal failure
• Ensures consistent transmission performance in vehicles like the Pontiac Firefly and Volkswagen Fox

Installation Notes and Tips

• Verify shaft and housing bore dimensions before installation to ensure compatibility
• Clean the shaft and bore area thoroughly to remove debris and old sealant
• Use appropriate tools to press the seal evenly into the housing bore without distortion
• Apply a light coating of transmission fluid on the seal lip before installation to reduce initial wear
• Inspect the seal after installation for proper seating and alignment
