Paccar MX-13 (2019–2021) 2128138 Holset HE400VG Remanufactured Turbocharger

Precision Remanufacturing

This Turbo Kings remanufactured Holset HE400VG turbocharger is engineered specifically for 2019–2021 Paccar MX-13 applications, restoring the precise boost control and VGT authority required for modern EPA-compliant engines. Every unit undergoes a complete teardown, measurement, and machining process to eliminate the common wear points found in high-mileage MX-13 turbos, including vane-track distortion, shaft scoring, thrust wear, and nozzle ring carbon seizure. The HE400VG is a critical component in maintaining stable emissions performance, low-RPM torque, and consistent fuel economy, and our remanufacturing process ensures each turbo returns to factory-grade performance characteristics.

Turbo Kings reestablishes all internal tolerances with calibrated machining and blueprinting, ensuring the turbine, compressor, and rotating assembly operate with minimal friction and optimal gas-flow geometry. The rotating group is rebuilt or replaced using hardened thrust components, upgraded bearing metallurgy, and precise journal clearances designed for high-temperature, high-load commercial duty cycles. The result is predictable spool behavior, sharp throttle response, and reliable torque delivery across the full operating range.

Seal Integrity & Flow Efficiency

Airflow efficiency and sealing performance are restored through multi-stage housing preparation and resurfacing. Turbine and compressor housings are media-cleaned, crack-checked, and machined for proper alignment with the CHRA. The bearing housing is rebuilt with new sealing rings, resurfaced oil galleries, and calibrated thrust geometry to eliminate oil leakage, smoke, and boost blow-by.

The VGT mechanism receives special attention: vane slots are reconditioned, the nozzle ring is resurfaced, and all sliding surfaces are corrected to factory clearances. This ensures smooth vane travel under high soot load and prevents the sticking and binding that commonly trigger derate conditions on MX-13 trucks. The assembled CHRA is VSR-balanced to maintain clean airflow, minimize vibration, and deliver stable boost under sustained thermal cycling.

What Makes Turbo Kings Different

Turbo Kings remanufacturing is engineering-driven, not cosmetic. Every turbo receives a documented rebuild workflow that includes component replacement with premium hardware, specification-matched machining, and high-speed balancing beyond Holset baseline requirements. The nozzle ring and vane mechanism are not merely cleaned—they are rebuilt, calibrated, and verified through mechanical sweep testing.

Each HE400VG is assembled with consistent torque sequencing, new fastening hardware where required, and strict dimensional control. No mixed cores, no mismatched housings, and no shortcuts. Fleets depend on repeatability, and every Turbo Kings unit is built to the same standard every time.
