What It Helps Address

• Transmission fluid seepage at the output shaft seal area.
• Contamination entering the transmission through a worn seal.
• Seal wear caused by shaft surface imperfections.
• Heat-related seal deterioration from poor lubricant circulation.
• Leak recurrence after replacing a damaged or hardened original seal.

Installation Notes and Tips

Verify shaft diameter, housing bore, width, and helix direction before installation. Clean the sealing surface and inspect the shaft for grooves, corrosion, or burrs that could affect sealing performance. Proper alignment during installation helps prevent case damage and ensures the seal seats evenly in the housing.

Quality Assurance

Timken oil and grease seals are built with precision sealing geometry and contamination-control features to support dependable drivetrain service. Part number 223580 is manufactured to match the listed Honda Civic and Honda Accord applications.
