Timken 223051 is a manual transmission output shaft seal built for Subaru applications that need reliable lubricant retention at the transmission shaft. It is a direct-fit sealing component for select Subaru Impreza, Legacy, Outback, and Forester models, including TY752-equipped vehicles.

Key Features

• Precision sealing design helps keep transmission oil in place and block outside contaminants.
• Reinforced outer case resists installation damage and adds durability.

• Vent holes promote lubricant flow around the seal lip to help manage heat buildup.

Detailed Description

This Timken output shaft seal is engineered for manual transmission service where shaft sealing is critical to maintaining proper lubricant levels. The seal’s construction focuses on controlled sealing contact, contamination exclusion, and durability under drivetrain operating conditions. It fits 1990-2004 Subaru Legacy, 2000-2004 Subaru Outback, 1993-2007 Subaru Impreza, and 1998 Subaru Forester applications on the left side, with TY752 notes listed for select Legacy, Forester, and Impreza fitments. This part cross-references National 223051 and SKF 11865A for the same application. Timken 223051 is a practical replacement choice when servicing a Subaru manual transmission output shaft seal on compatible Legacy, Impreza, Outback, or Forester models.

Common Issues This Seal Can Address

• Transmission fluid seepage at the output shaft
• Contamination entering the seal area
• Wear-related sealing loss from shaft surface imperfections
• Heat-related seal deterioration around the lip area
• Leak recurrence after a worn or damaged seal is replaced

Installation Notes and Tips

Inspect the shaft surface, seal bore, and surrounding components before installation. Clean the sealing area thoroughly and verify the replacement seal is oriented correctly for the transmission output shaft. On Subaru manual transmission applications, confirm the left-side fitment and any TY752 notes before installation. Proper seating is important to avoid distortion or premature leakage.
