What It Helps Address

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

Installation Notes and Tips

Inspect the input shaft, seal bore, and surrounding surfaces before installation. Clean away old seal material, debris, and lubricant residue, then verify the replacement seal seats evenly in the housing. For Subaru manual transmission service, confirm the transmission code and vehicle application before installation to match the correct seal to the gearbox.

Quality Assurance

Timken oil and grease seals use precision sealing construction and a reinforced outer case to support dependable service in manual transmission applications. The design also includes contamination exclusion features and venting to help manage operating conditions around the seal lip.
