Timken 710172 Manual Transmission Input Shaft Seal

Timken 710172 is a manual transmission input shaft seal built for leak control and contamination resistance in select Toyota applications. It is a direct-fit service part for manual transaxles used in the Toyota Celica, Paseo, and MR2.

Key Features

• Precision sealing design helps retain transmission lubricant and block outside contaminants
• Reinforced outer case helps resist installation damage and supports durability
• Ribbed rubber inner diameter seals minor spindle imperfections and promotes positive seating
• Internal contamination exclusion system helps reduce debris intrusion that can lead to leakage
• Vent holes allow lubricant flow around the seal lip to help manage heat buildup

Detailed Description

This Timken manual transmission input shaft seal is engineered for service in Toyota manual transaxles including E50F2, E55F2, E55F5, E56F2, E56F5, E57F5, E150F, and S54 units. It is used in 1988-1999 Toyota Celica, 1999 Toyota Paseo, and 1991-1995 Toyota MR2 applications. The Timken 710172 seal combines a reinforced case, ribbed sealing surface, and debris exclusion features to support consistent sealing at the input shaft.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Transmission fluid seepage at the input shaft
• Contamination entering the manual transaxle area
• Seal wear from heat buildup around the lip
• Improper seating caused by minor shaft imperfections
• Leak-related service issues during manual transmission repair

Installation Notes and Tips

Verify the transmission code before installation to confirm the correct application. Inspect the shaft surface for scoring, clean the bore thoroughly, and install the seal squarely to avoid lip damage. Use proper seal driver tools and follow factory service procedures for the Toyota Celica, Paseo, or MR2 manual transmission.

Quality Assurance

Timken oil and grease seals are built with precision sealing designs and durability-focused construction for drivetrain service applications.
