Detailed Description

FAG SS3753 is a transmission sealing component designed for front oil pump service where accurate dimensions and stable sealing performance matter. The nitrile sealing material is selected for transmission environments, while the spring-loaded rubber seal design helps maintain contact at the sealing surface. With a bore diameter of 2.323 inches and an outside diameter of 2.328 inches, this seal is sized for specific OE-style applications rather than universal use. It is a direct-fit option for vehicles including the 2007-2012 Nissan Versa, 2003-2006 Nissan Sentra, 1999-2002 INFINITI G20, 1991-1996 INFINITI G20, and 1995-1998 Nissan 200SX, all in front-position applications. The FAG SS3753 is also referenced by SKF 16536 and National 710442.

What It Helps Address

• Transmission fluid seepage at the oil pump seal area
• Loss of sealing tension from an aged or hardened seal
• Contamination entry around the pump sealing surface
• Service issues tied to incorrect seal dimensions
• Front transmission seal replacement on select Nissan and INFINITI models

Installation Notes and Tips

Verify the bore diameter, outside diameter, and seal width before installation to confirm the correct transmission application. Inspect the pump bore and sealing surface for wear, scoring, or debris before fitting the new seal. Clean the mating area thoroughly and install the seal squarely to avoid distortion. Confirm vehicle-specific fitment for the exact year, model, and front-position application before assembly.

Quality Assurance

FAG seals are engineered to meet vehicle manufacturer specifications and are produced with supplier coordination to support consistent sealing performance. The SS3753 is built for demanding seal applications where dimensional accuracy and contamination control are important.
