Timken 7188S Manual Transmission Shift Shaft Seal

Timken 7188S Manual Transmission Shift Shaft Seal

The Timken 7188S manual transmission shift shaft seal is built for Chrysler, Dodge, and related New Process manual transmission applications that need dependable sealing at the shift shaft or output shaft area. It is engineered to help keep lubricant in the transmission and keep road debris out, supporting cleaner operation in older Chrysler Design and New Process-equipped vehicles.

Key Features

• Precision sealing design helps reduce lubricant loss and contamination entry
• 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 block debris that can lead to leakage
• Vent holes allow lubricant flow around the seal lip to help manage heat buildup
• Timken 7188S is a direct-fit sealing component for manual transmission service

Detailed Description

Timken 7188S is a manual transmission shift shaft seal designed for service on a wide range of Chrysler and Dodge vehicles, including Chrysler Newport, Dodge Dart, Dodge Charger, and Dodge Challenger applications. This seal uses a reinforced case and a ribbed inner sealing surface to help maintain contact on the shaft while accommodating minor surface imperfections. The design also supports lubricant circulation around the lip, which helps reduce heat concentration at the sealing area.

This part is used in manual transmission sealing repairs where the original seal has hardened, worn, or begun leaking. It is a practical choice for Chrysler Design and New Process output shaft seal applications across many classic and late-1970s/early-1980s vehicles. Part number 7188S is also a useful reference when sourcing the correct Timken seal for these drivetrain repairs.

Installation Notes and Tips

Confirm the transmission style and seal location before installation, especially on Dodge trucks and vans with New Process output shaft seal applications. Clean the shaft and housing thoroughly, inspect for grooves or scoring, and install the seal squarely to avoid lip damage. A light film of clean transmission lubricant on the sealing lip can help initial startup contact.
