Detailed Description

Timken 224464 is engineered for the automatic transmission extension housing where consistent sealing is critical to keeping fluid inside the transmission and contaminants outside. The seal’s reinforced case supports installation, while the ribbed inner diameter helps maintain contact on shafts with minor surface variation. Its vented design also helps circulate lubricant around the lip area to reduce heat concentration during operation. This part cross-references National 224464 for the same application.

Compatible With select Nissan and Infiniti vehicles, including Fits 2009-2019 Nissan 370Z, N/A; Fits 1998-2019 Nissan Frontier, N/A; Fits 2004-2015 Nissan TITAN, N/A; Fits 2016-2019 Nissan TITAN XD, N/A; and Fits 2008-2013 Infiniti G37, N/A.

What This Seal Helps Address

• Transmission fluid seepage at the extension housing
• Contamination entering the tail housing area
• Seal wear caused by heat buildup around the lip
• Leakage related to minor shaft surface imperfections
• Damage from a weak or distorted original seal case

Installation Notes and Tips

Confirm shaft diameter, housing bore, width, and helix direction before installation. Clean the housing bore and shaft surface thoroughly, and inspect for scoring, burrs, or corrosion that could affect sealing. Use proper seal installation tools to keep the case square during press-in and avoid deforming the sealing lip. Verify the application against the vehicle’s transmission configuration before service.
