Detailed Description

Built by National, a long-established name in sealing technology, this output shaft seal is part of the 710300 series and is designed to help maintain a tight seal where the transmission output shaft exits the case. The nitrile sealing material is selected for oil resistance, while the counter-clockwise spiral lip design supports controlled sealing performance in manual transmission service.

Installation Notes and Tips

Confirm the transmission code and shaft dimensions before installation, especially on Subaru TY751, TY756, TY758, TY856, TG5D7, TG5D8, TG5D9, TZ1B8, and related applications. Inspect the shaft surface and housing bore for wear, scoring, or corrosion before pressing in the new seal. Clean the sealing area thoroughly so the nitrile lip seats evenly and maintains proper oil control.
