Detailed Product Overview

Timken 3655S is engineered as an engine intermediate shaft seal for applications across 1981-2002 Chrysler, Dodge, and Plymouth vehicles. It is commonly selected for Chrysler Town & Country, Dodge Caravan, and Plymouth Voyager service work where a worn shaft seal can lead to oil seepage or contamination at the sealing surface. This part number, 3655S, is also cross-referenced by Atlantic Automotive Engineering 3655 for the same application.

Common Problems This Seal Can Address

• Oil leakage at the intermediate shaft area
• Grease or lubricant loss from a worn seal lip
• Contamination entering the sealing interface
• Heat-related seal wear from poor lubricant circulation
• Leakage caused by minor shaft surface imperfections

Installation Notes and Tips

Inspect the shaft surface, housing bore, and surrounding components before installation. Clean away old seal material and debris, then install the seal squarely to avoid distortion of the outer case. Verify the application by year, make, model, and position before ordering, since Timken 3655S is listed for multiple front, rear, and N/A positions across Chrysler, Dodge, and Plymouth platforms.

Quality Assurance

Timken oil and grease seals use precision sealing designs, a reinforced outer case, and contamination-exclusion features to support consistent sealing performance in automotive service.
