Application & Compatibility

Source application path clues for buyer verification. These are source category/application paths, not confirmed fitment claims:

This thrust bearing is listed for CAT 3208 425HP marine engines equipped with S4TW-509 turbochargers. The application path serves as a reference clue for buyers to verify fitment against their specific engine code and turbo configuration.

• CAT > CAT MARINE > CAT 3208 425HP
• Reference Application: CAT > CAT MARINE > CAT 3208 425HP
• Turbo Model: S4TW-509

Buyers should cross-check the engine displacement, horsepower rating, and turbo model to ensure this replacement application aligns with their fleet or repair requirements. Do not assume universal fitment across all CAT 3208 variants; verify the specific turbo setup and production year to avoid installation errors.

Technical Notes

The S4TW-509 turbocharger is a fixed-geometry unit, meaning it does not utilize variable turbine geometry (VNT) or adjustable vanes. This thrust bearing supports the turbine shaft to manage axial loads during operation. Because the S4TW-509 is a specific model, buyers must verify that their turbocharger assembly matches this designation rather than assuming cross-compatibility with other Garrett or S4 series variants. Technical fitment support is available to help confirm the correct bearing specification for your specific CAT 3208 marine engine setup.
