New 10R2027 Caterpillar C13 ACERT Garrett GTA4702B Turbocharger - Turbo Centre Production Line

The 10R2027 Turbocharger is a purpose-matched Garrett GTA4702B assembly for Caterpillar C13 ACERT 12.5L, Twin-turbo C13 ACERT low-pressure position. It is built around the exact compressor, turbine, housing, and control specification associated with part number 10R2027, so fitment should be confirmed from the engine serial number and original turbo tag rather than by engine family alone.

The GTA4702B is the low-pressure, large-frame turbo in the Caterpillar C13 ACERT compound arrangement. It supplies the majority of the airflow at higher engine load and feeds compressed air to the 10R8733 high-pressure turbo. Correct wheel sizing and housing geometry allow the two stages to share the compression work, which helps the C13 maintain strong top-end airflow without forcing the smaller high-pressure turbo beyond its intended operating range.

This listing is supplied as the turbocharger configuration shown. Correct installation requires clean oil feed and drain paths, a sealed charge-air and exhaust system, proper air filtration, and confirmation that the original failure did not leave debris or contamination in the engine system.

Turbo Centre Production Line units are assembled from new components to controlled specifications. The rotating group is balanced, bearing clearances and oil passages are checked, housings and control hardware are inspected, and wastegate or vane operation is verified where applicable before shipment. The result is a direct-replacement turbo built for dependable highway, vocational, fleet, and industrial service without a core return requirement.
