Timken 224020 Manual Transmission Output Shaft Seal - Front or Rear

Timken 224020 Manual Transmission Output Shaft Seal

Timken 224020 is a manual transmission output shaft seal built for precise lubricant control and dependable sealing performance. It is designed for applications such as Toyota Camry, Toyota Tacoma, Lexus RX330, and Ford Fiesta where a tight seal at the output shaft is critical to keeping transmission fluid where it belongs.

This seal uses an S-Nitrile construction, a reinforced outer case, and a ribbed rubber inner diameter to help seat securely on the shaft and accommodate minor surface imperfections. The internal contamination exclusion system and vent holes support cleaner operation by reducing debris intrusion and helping manage heat around the seal lip.

Key Features

• Manual transmission output shaft seal for transmission sealing service
• S-Nitrile material for oil and grease resistance
• Reinforced outer case helps reduce installation damage
• Ribbed inner diameter promotes positive shaft seating
• Internal contamination exclusion system helps block debris entry
• Vent holes allow lubricant flow around the seal lip to help reduce heat build-up
• Helix type: CW-clockwise
• Dimensions: 2.176 in. outside diameter, 1.575 in. shaft diameter, 2.165 in. housing bore, 0.315 in. width

Detailed Description

Timken 224020 is engineered for manual transmission output shaft sealing where consistent lubricant retention matters. The seal’s precision design helps prevent fluid escape while limiting the entry of contaminants that can contribute to leakage and wear. Its reinforced outer case adds durability during installation, while the ribbed rubber inner diameter helps the seal conform to minor spindle imperfections for a more secure fit. This part cross-references National (e.g., 224020, 473677) for the same application.

Compatible With 1988-2006 Toyota Camry, Front; 1995-2004 Toyota Tacoma, Front; 2004-2006 Lexus RX330, Front; and 2011-2018 Ford Fiesta, N/A. It also serves other listed Toyota, Lexus, Isuzu, BMW, Chevrolet, and Ford applications across the provided fitment range, including Toyota 4Runner, Sienna, Tundra, Highlander, and Lexus ES300/ES330 models. Timken 224020 is a direct-fit service part for vehicles that require the specified shaft, bore, and width dimensions.

What It Helps Address

• Transmission fluid leakage at the output shaft
• Contamination entering the seal area
• Seal wear caused by heat build-up
• Poor sealing on shafts with minor surface imperfections
• Damage during seal installation

Installation Notes and Tips

Verify shaft diameter, housing bore, width, and helix direction before installation. Clean the sealing surface and inspect the shaft for scoring or excessive wear before pressing the seal into place. Use proper installation tools to avoid distorting the reinforced case, and confirm the seal seats evenly in the bore. For best results, match the application to the listed position and transmission configuration.
