  • CAT > CAT TRACTOR > CAT 3126E

This actuator is listed for CAT 3126E engine applications, specifically within CAT tractor units. It is associated with S300G turbocharger configurations. Use the OEM reference numbers FOR 171574 AC, FOR 171595 AC, FOR 171998 AC, FOR 172007 AC, and FOR 176864 AC to cross-check fitment against your existing unit. Verify the actuator body, mounting bracket, and control rod dimensions against your specific turbocharger before ordering. Confirm that the spring rate and related hardware alignment match your current setup to ensure proper wastegate operation.

Technical Notes

The FOR 178468 AC actuator features a cylindrical brass-colored body with a silver mounting bracket and a control rod with a slotted end. Visible concentric ridges on the housing face and three mounting holes on the bracket aid in visual identification. Buyers should verify the spring rate, related hardware alignment, and mounting dimensions against their existing S300G unit. Confirm that the actuator body and bracket configuration match the specific CAT 3126E turbocharger setup before installation. Use the provided OEM reference numbers to cross-check fitment details.

Product FAQ

Confirm the spring rate and operating pressure range of the FOR 178468 AC actuator match the S300G turbocharger specifications for your CAT 3126E engine. Verify against your existing unit or OEM documentation.

While this actuator controls the wastegate, verify the nozzle ring vane count and height on the turbine housing separately. Ensure the actuator related hardware aligns correctly with the vane mechanism on the S300G assembly.

If replacing the actuator as part of a CHRA/core rebuild, ensure the new actuator does not alter the static balance of the turbo assembly. Verify the mounting bracket and control rod length match the original configuration.

This actuator is referenced by FOR 171574 AC, FOR 171595 AC, FOR 171998 AC, FOR 172007 AC, and FOR 176864 AC. Use these numbers to cross-check fitment for your specific CAT 3126E application.
