Timken 222745 Manual Transmission Output Shaft Seal - Rear

Timken 222745 Manual Transmission Output Shaft Seal

Timken 222745 is a manual transmission output shaft seal built to retain lubricant and block road debris from entering the transmission. It is a direct-fit sealing component for select Subaru manual transaxle applications, including Legacy and Impreza models, as well as Subaru Standard transmissions listed below.

Key Features

• Precision sealing design helps control oil and grease leakage at the output shaft
• Reinforced outer case helps resist installation damage and improve durability
• Ribbed rubber inner diameter helps seal minor shaft imperfections and promote positive seating
• Internal contamination exclusion system helps keep debris out of the seal area
• Vent holes allow lubricant flow around the seal lip to reduce heat build-up
• N-Polyacrylate construction for transmission sealing service
• Dimensions: 1.781 in. outside diameter, 1.772 in. housing bore, 1.063 in. shaft diameter, 0.354 in. width
• Helix type: CCW counter clockwise

Detailed Description

This Timken transmission output shaft seal is engineered for Subaru manual transmission service where a stable seal is needed at the output shaft. The seal’s reinforced case supports installation, while the ribbed inner diameter helps maintain contact on shafts with minor wear or surface variation. Timken 222745 is sized for a 1.063-inch shaft diameter and a 1.772-inch housing bore, making it a precise replacement for the listed Subaru Legacy, Impreza, and Subaru Standard applications. This part cross-references National 222745 for the same application.

What It Helps Address

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

Installation Notes and Tips

Verify shaft diameter, housing bore, width, and helix direction before installation. Clean the bore and shaft thoroughly, inspect for scoring or corrosion, and confirm the seal is seated squarely to avoid distortion. Use proper installation tools to protect the outer case and sealing lip during service.

Quality Assurance

Timken designs oil and grease seals with precision sealing features and contamination control details for drivetrain service. This part is built to the listed dimensions and application data for Subaru manual transmission output shaft use.
