Timken 712007 Manual Transmission Input Shaft Seal - Front or Inner

Manual Transmission Input Shaft Seal for Hyundai, Mitsubishi, Dodge

Timken 712007 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 wide range of Hyundai, Mitsubishi, Dodge, Chrysler, and Ford manual transmission applications.

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 helps seal minor spindle imperfections and promote seating
• Internal contamination exclusion system helps reduce debris intrusion
• Vent holes promote lubricant flow around the seal lip to help manage heat buildup

Detailed Description

Built for manual transmission service, Timken part number 712007 is used where a dependable input shaft seal is needed to maintain proper lubricant retention. The seal’s reinforced construction and ribbed inner diameter are designed to support a secure fit on the shaft, while the contamination exclusion features help keep abrasive material out of the transmission. This makes it a practical replacement for vehicles such as the Hyundai Accent, Hyundai Elantra, Hyundai Sonata, Hyundai Tiburon, Mitsubishi Lancer, and Dodge Colt applications listed in the fitment data. This part cross-references Monroe Shocks & Struts (e.g., 172286) for the same application.

What It Helps Fix

• Transmission fluid seepage at the input shaft
• Contamination entering the manual transmission housing
• Seal wear caused by heat buildup around the lip
• Leakage related to minor shaft surface imperfections
• Noise or drivability concerns tied to low lubricant level

Installation Notes and Tips

Confirm transmission code and seal dimensions before installation, especially on Hyundai and Mitsubishi manual transmission variants with application-specific notes. Inspect the input shaft surface for scoring or wear, clean the bore thoroughly, and install the seal squarely to avoid distortion. For best results, verify the exact year, make, model, and position listed in the fitment data, including front and inner applications where noted.
