CAT C15 10R-2407 2005–07 High Pressure Remanufactured Turbocharger

Precision Remanufacturing

This Turbo Kings remanufactured high-pressure (HP) turbocharger replaces the OEM 10R-2407 unit used on 2005–2007 CAT C15 ACERT engines. As the primary boost-building turbo in the ACERT twin-turbo architecture, the HP unit is responsible for rapid spool, clean combustion, and stable low-RPM torque. Turbo Kings begins each reman with a complete teardown, degreasing, and deep chemical cleaning using high-temperature alkaline treatment and ultrasonic agitation. All components—turbine housing, compressor cover, bearing housing, wastegate assembly, and hardware—are evaluated for heat stress, fatigue, pitting, erosion, housing distortion, and carbon intrusion.

The HP turbo belongs to the BorgWarner 741154 series, known for its precise scroll geometry and compact high-efficiency turbine. Turbo Kings restores every critical surface, including the thrust plate seat, journal bore, ring lands, and bearing carrier. Each CHRA is rebuilt with brand-new bearings, thrust components, seals, piston rings, O-rings, V-band hardware, and fasteners. Bearing clearances are digitally confirmed, and the oil passages are cleaned and verified to guarantee stable oil pressure and lubrication under heavy duty cycles. Every rotating assembly is high-speed VSR balanced to eliminate harmonics and ensure the HP wheel accelerates smoothly under load.

Seal Integrity & Flow Efficiency

Because the C15 HP turbo operates under extreme exhaust density and rapid temperature cycling, proper sealing is essential. Turbo Kings restores the sealing surfaces in the turbine housing, the backplate, and the compressor cover to prevent boost loss, oil migration, and exhaust leakage. The wastegate mechanism is cleaned, machined when needed, and calibrated for proper crack pressure and stroke, ensuring accurate control of exhaust flow to protect the turbine speed during full-load conditions.

Flow efficiency is verified by inspecting and correcting the compressor volute geometry, restoring the roundness of the inlet, confirming compressor-wheel tip clearance, and ensuring a perfect seal between center housing and compressor cover. Turbine scroll surfaces are bead-finished to reduce carbon adhesion and maintain consistent boost response over the life of the unit. The result is a remanufactured HP turbo that restores the crisp, immediate spool required for ACERT’s staged-boost system.

What Makes Turbo Kings Different

Every Turbo Kings HP turbo is remanufactured to exceed standard OEM refurbishment practices. Each unit receives:

• Complete CHRA rebuild with all-new components

• High-speed balancing of the rotating assembly

• Digitally verified bearing and thrust clearances

• Restored wastegate operation and calibration

• Corrected scroll geometry and sealing surfaces

• Pressure-tested compressor and turbine housings

• Clean-room final assembly with serialized documentation

Turbo Kings focuses on engineering precision, long-term endurance, and consistent boost delivery—not quick cosmetic rebuilds.

Why Fleets and Owner-Operators Trust Turbo Kings

The CAT C15 ACERT HP turbo plays a crucial role in drivability, emissions stability, and overall engine performance. A properly remanufactured Turbo Kings HP unit restores:

• Fast spool and quick low-RPM torque
