What It Helps Address

• Transmission fluid seepage at the input shaft
• Contamination entering the bellhousing or seal area
• Heat-related seal wear from poor lubricant circulation
• Leakage caused by minor shaft surface imperfections
• Seal damage during installation on older manual transmissions

Installation Notes

Verify shaft diameter, housing bore, and seal width before installation to confirm proper fit. Clean the bore and shaft surface thoroughly, inspect for scoring or wear, and install the seal squarely to avoid lip distortion. This part is used in manual transmission service on vehicles such as Audi A4, Volkswagen Passat, and Porsche 944, so matching the exact transmission application is important before assembly.

Quality Assurance

Timken oil and grease seals use precision sealing designs, a reinforced outer case, and contamination-control features to support consistent service life in drivetrain applications. Part number 222540 is built to the listed dimensions and material specification for direct replacement use in confirmed fitments.
