Timken 225545 Manual Transmission Output Shaft Seal - Left or Right

Timken 225545 Manual Transmission Output Shaft Seal

The Timken 225545 manual transmission output shaft seal is built to retain lubricant at the transmission output shaft while helping block dirt and debris from entering the sealing area. It is a direct-fit service part for select Acura RL, TL, and Legend applications, including left and right positions where listed.

Key Features

• Precision sealing design helps control oil and grease leakage at the output shaft
• Reinforced outer case helps reduce installation damage and improve durability
• S-Nitrile construction provides sealing performance for transmission service
• Ribbed rubber inner diameter helps seal minor shaft imperfections and promote seating
• Internal contamination exclusion system helps keep debris out of the seal lip area
• Vent holes allow lubricant flow around the seal lip to help reduce heat buildup
• Outside diameter: 2.962 in. (75.23 mm)
• Shaft diameter: 2.165 in. (55.00 mm)
• Housing bore: 2.953 in. (75.00 mm)
• Width: 0.394 in. (10.00 mm)

Detailed Description

Timken 225545 is a manual transmission output shaft seal engineered for accurate fitment in select Acura driveline applications. It is listed for 1991-1995 Acura Legend, left and right; 1996-1999 Acura TL, right; 1996-1999 Acura RL, right; and 2000-2004 Acura RL, N/A position. This part cross-references Gates (e.g., 21627, 22031) for the same application. The seal’s ribbed inner diameter helps accommodate minor shaft wear, while the reinforced outer case supports cleaner installation and long-term sealing performance. Timken 225545 is a practical replacement when servicing a leaking transmission output shaft seal on Acura RL, Acura TL, or Acura Legend models.

What This Seal Helps Address

• Transmission fluid seepage at the output shaft
• Contamination entering the seal area from road debris
• Leakage caused by minor shaft surface imperfections
• Heat-related seal wear from poor lubricant circulation
• Seal damage during installation on the housing bore

Installation Notes and Tips

Verify shaft diameter, housing bore, and width before installation to confirm the seal matches the transmission case. Clean the bore and shaft surface thoroughly, and inspect for scoring or wear that could affect sealing. Install the seal squarely to avoid distortion of the outer case or sealing lip. For Acura Legend, Acura TL, and Acura RL applications, confirm the listed position before ordering, since fitment varies by year and drivetrain location.

Quality Assurance

Timken oil and grease seals are built with precision sealing features, contamination control, and durability-focused construction for transmission service. The 225545 seal reflects Timken’s engineering approach to retaining lubricant and helping protect internal components from debris intrusion.
