Detailed Description

Timken 224026 is engineered as a manual transmission output shaft seal for vehicles that require dependable lubricant retention at the transmission output shaft.

What It Helps Solve

• Transmission fluid seepage at the output shaft seal
• Contamination entering the seal area and affecting sealing performance
• Leakage caused by minor shaft surface imperfections
• Heat buildup around the seal lip during operation
• Poor seal seating in the housing bore

Installation Notes and Tips

Verify shaft diameter, housing bore, and width before installation to confirm proper fit. Inspect the shaft surface for scoring or wear before replacing the seal, and clean the bore thoroughly so the outer case seats evenly. Use care during installation to avoid distorting the seal lip or damaging the reinforced case. Confirm the vehicle’s transmission position and application details against the fitment list, including Fits 2008-2017 Honda Accord, right and Fits 2006-2010 Honda Civic, left.
