Paccar MX-13 5640249 (2021–Present) Holset HE400VG Remanufactured Turbocharger

Precision Remanufacturing

This Turbo Kings remanufactured Holset HE400VG turbocharger, built under primary part number 5640249, is engineered for 2021–Present Paccar MX-13 applications. Every unit undergoes a complete teardown, dimensional inspection, machining of worn surfaces, and restoration of critical VGT components to ensure factory-calibrated performance. The HE400VG is a key emissions and airflow component on modern MX engines, and our remanufacturing process brings the turbo back to OEM-validated control, efficiency, and durability.

Our CHRA units are rebuilt with new journal bearings, thrust components, and seal rings, then dynamically balanced at high speed to restore stable rotation and precise aerodynamic flow. Compressor and turbine geometries are verified for proper clearance, ensuring fast spool, smooth transient response, and consistent boost throughout the operating RPM range.

Seal Integrity & Flow Efficiency

Turbo Kings restores full seal integrity by resurfacing all critical mating surfaces and renewing the internal oil-control system. Bearing housings are cleaned and recut where required to maintain stable lubrication, eliminate oil leakage, and prevent boost contamination. The turbine and compressor housings undergo crack inspection, blast preparation, and alignment machining to guarantee uniform expansion and sealing under heat load.

The variable-geometry system—the heart of the HE400VG—is rebuilt to exact travel and alignment tolerances. Each vane, slot, and unison component is corrected for smooth, bind-free motion even under soot exposure. The restored VGT system ensures proper exhaust flow modulation, optimized EGR performance, and reliable exhaust-brake operation for MX-13 engines across all duty cycles.

What Makes Turbo Kings Different

Turbo Kings reman turbochargers follow a strict engineering-driven process rather than a cosmetic refresh. Each HE400VG receives upgraded thrust materials, precision-balanced rotating assemblies, and calibrated VGT components. Housing flatness, ring alignment, and turbine–compressor relationships are measured and corrected using controlled machining steps to return the turbo to OE-standard performance.

We ensure repeatability across all builds through standardized torque specifications, component replacement, and flow validation. No mismatched housings or mixed-batch internals—every turbo is assembled to maintain consistent performance for fleet-wide reliability.

Our Process at a Glance

• Full disassembly and inspection

• Housing preparation, machining, and dimensional correction

• Replacement of all seals, bearings, and thrust components

• VGT mechanism restoration and calibrated travel adjustment

• High-speed VSR balancing of the rotating assembly

Why Fleets and Owner-Operators Trust Turbo Kings

The HE400VG controls boost, backpressure, and emissions response on late-model MX-13 engines. A properly rebuilt unit restores acceleration, reduces regen frequency, stabilizes EGTs, and improves drivability under load. Turbo Kings remanufactured turbos are built for demanding commercial operations and provide dependable, repeatable performance supported by strict engineering oversight.
