Product Details

National 223215 is a transmission sealing component designed around the listed shaft and housing dimensions for Suzuki Samurai and Suzuki Sidekick models equipped with the MM5 transmission. The nitrile seal material and spiral lip profile are specified to support consistent sealing at the output shaft, where transmission fluid retention is critical.

Common Issues This Seal Can Address

• Transmission fluid leaking from the output shaft area
• Oil seepage around the manual transmission tail housing
• Seal wear from age, heat, and mileage
• Fluid loss that can leave residue on the transmission exterior
• Contamination entering through a worn output shaft seal

Installation Notes and Tips

Verify shaft diameter, housing bore, and seal width before installation. Clean the seal bore and shaft surface thoroughly, and inspect the output shaft for grooves or damage that could affect sealing. Confirm MM5 transmission application on Suzuki Samurai and Suzuki Sidekick models before ordering. Proper alignment during installation helps prevent lip damage and premature leakage.
