Product FAQ

This part references OE numbers including 0R6605 TW, 178232 TW, and 189485. Verify your specific engine serial number to confirm the correct replacement application.

It is designed as a replacement for S4TW-509 turbochargers used in CAT 3208 425HP applications. Cross-check your turbo model and OEM part number to ensure accurate fitment.

Ensure the bypass valve opens and closes freely without sticking, as restricted flow can cause excessive boost pressure. Inspect the actuator related hardware for wear or damage during reassembly.

Confirm that the thrust bearing matches the original design specifications for axial load handling. Using incorrect bearings can lead to premature CHRA failure and oil leakage.
