Detailed Application Coverage

FAG SS2904 is specified for select Oldsmobile engine sealing applications, including 1950 Oldsmobile 88, 1954-1957 Oldsmobile 88, 1950-1962 Oldsmobile 98, 1954-1957 Oldsmobile Starfire, and 1961-1962 Oldsmobile Starfire. The seal dimensions and construction are important for matching the timing cover bore and maintaining proper sealing performance in vintage Oldsmobile engine assemblies.

This part cross-references Gates 18581 for the same application.

What This Seal Helps Address

• Oil seepage at the timing cover sealing surface
• Contamination entering the sealed engine area
• Grease or lubricant loss at the seal interface
• Wear-related sealing issues in aging Oldsmobile engine components
• Dimensional mismatch when replacing an OE-style timing cover seal

Installation Notes and Tips

Verify bore diameter, seal outside diameter, and seal width before installation to confirm the seal matches the housing and shaft dimensions. Clean the sealing surfaces thoroughly and inspect the cover and mating components for wear, scoring, or corrosion that could affect sealing performance. For best results, install the seal squarely and follow the vehicle service procedure for the specific Oldsmobile engine.

Quality Assurance

FAG designs seals to meet vehicle manufacturer specifications and works with suppliers to maintain its quality standards. The SS2904 uses nitrile sealing material and a spring-loaded, auxiliary-lip construction for demanding engine sealing applications.
