Detailed Description

This Timken output shaft seal is designed for manual transmission service where maintaining lubricant inside the transmission is critical. The precision sealing design helps control oil escape while the reinforced outer case and ribbed inner diameter support a secure fit at the housing and shaft interface. Timken 224040 measures 2.373 inches outside diameter, 1.575 inches shaft diameter, 2.362 inches housing bore, and 0.394 inches width, with S-Nitrile material selected for sealing applications. It is a practical replacement for Volvo manual transmission output shaft seal service and for Toyota Camry, Avalon, and Solara transmission repairs where the listed dimensions and fitment match.

What It Helps Solve

• Transmission fluid leakage at the output shaft seal
• Contamination entering the transmission through a worn seal
• Seal fit issues caused by minor shaft surface imperfections
• Heat-related seal wear from poor lubricant circulation at the lip
• Noise or drivability concerns related to low transmission fluid level

Installation Notes and Tips

Verify shaft diameter, housing bore, and width before installation to confirm the seal matches the transmission case and output shaft. Inspect the shaft surface for scoring or wear before pressing in the new seal, and keep the sealing lip clean during assembly. For fitment reference, this part fits 2008-2013 Volvo C30, Left, M66; 2005-2007 Volvo V50, Left, M66; 2001-2005 Volvo S60, Left; and 1994-2006 Toyota Camry, N/A.
