Timken 710397 Manual Transmission Output Shaft Seal - Left or Right

Timken 710397 Manual Transmission Output Shaft Seal

Timken 710397 is a manual transmission output shaft seal built for select Nissan and INFINITI applications. It is engineered to retain transmission lubricant, block contaminants, and support consistent sealing at the output shaft.

Key Features

• Precision sealing design helps control lubricant loss and keep debris out of the transmission
• Reinforced outer case resists installation damage and adds durability
• Ribbed rubber inner diameter seals minor spindle imperfections and promotes positive seating
• Internal contamination exclusion system helps reduce debris penetration that can lead to leakage
• Vent holes allow lubricant flow around the seal lip to reduce heat build-up

Detailed Description

This Timken transmission seal is designed for manual transmission output shaft service where reliable fluid retention matters. The seal’s reinforced construction and ribbed inner diameter support a secure fit on the shaft surface, while the contamination exclusion features help protect the sealing area from dirt and road debris. Timken 710397 is a direct-fit service part for vehicles including 2003-2007 Nissan Murano, 1996-1999 INFINITI I30, 1995-1999 Nissan Maxima, 1993-1994 Nissan Altima, and 1992-1993 Nissan Sentra. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Transmission fluid leaking from the output shaft area
• Contamination entering the seal lip and sealing surface
• Seal wear caused by heat build-up around the shaft
• Poor sealing on shafts with minor surface imperfections
• Repeat leakage after a previous seal replacement

Installation Notes and Tips

Inspect the output shaft, seal bore, and surrounding components before installation. Clean the sealing surface thoroughly and verify the shaft is free of burrs or heavy wear. Install the seal squarely to avoid distortion, and confirm the lip seats evenly after assembly. For fitment verification, match the vehicle year, make, model, and transmission position before ordering Timken 710397.
