Installation Notes and Tips

Verify shaft, housing bore, and width dimensions before installation. Confirm the transmission code and application notes, especially on Suzuki SE5F-A, Suzuki MV2, and 5-speed Suzuki transmission listings. Clean the bore and shaft surface thoroughly before installing National 222030 to help the seal seat evenly and maintain proper lip contact.
