Timken 223235 Manual Transmission Input Shaft Seal - Front

Manual Transmission Input Shaft Seal for Toyota and Geo

Timken 223235 is a manual transmission input shaft seal built to retain lubricant at the transmission input shaft while helping block dirt and debris from entering the assembly. It is a direct-fit sealing component for a range of Toyota, Geo, Acura, and Chevrolet applications, including Toyota Corolla, Toyota Celica, and Geo Prizm fitments.

Key Features

• Precision sealing design helps control oil and grease leakage at the input shaft
• Reinforced outer case helps resist installation damage and improve durability
• Ribbed rubber inner diameter seals minor spindle imperfections and supports positive seating
• Internal contamination exclusion system helps reduce debris intrusion that can lead to leakage
• Vent holes promote lubricant flow around the seal lip to help manage heat buildup
• N-Polyacrylate construction for sealing performance in transmission service

Detailed Description

This Timken transmission seal is engineered for manual gearbox service where a stable seal at the input shaft is critical. The 223235 seal uses a 1.820-inch outside diameter, 1.260-inch shaft diameter, 1.811-inch housing bore, and 0.236-inch width, with a clockwise helix type. These dimensions support accurate fitment in applications such as Toyota Corolla, Toyota Celica, Toyota MR2, Toyota Tercel, Geo Prizm, Geo Storm, Geo Spectrum, Chevrolet Nova, and Acura NSX models listed in the fitment data. This part cross-references National 223235 for the same application.

What It Helps Address

• Transmission fluid seepage at the input shaft
• Contamination entering the manual transmission housing
• Seal wear caused by heat buildup around the lip area
• Leakage related to minor shaft surface imperfections
• Reduced sealing performance from a damaged or aged input shaft seal

Installation Notes and Tips

Verify shaft diameter, housing bore, width, and helix direction before installation. Clean the bore and shaft surface thoroughly, and inspect for scoring or wear that could affect sealing. Proper alignment during installation is important to avoid damaging the reinforced outer case or seal lip. Confirm vehicle-specific fitment for your manual transmission application before ordering.

Quality Assurance

Timken oil and grease seals are built with precision sealing features and contamination control details intended for dependable transmission service. The design focuses on lubricant retention, debris exclusion, and durability in demanding drivetrain environments.
