HE400FG wastegate turbocharger is developed by Holset for Cummins QSL9、6CT 8.3L & 6LTAA9.3L heavy-duty industrial diesel engines. It compresses intake air to raise cylinder air density, optimizes fuel combustion efficiency and low-speed torque output, cuts fuel consumption and exhaust emissions, conforms to domestic and international non-road emission standards, serving as premium aftermarket replacement spare parts for construction machinery and fixed generator equipment.

Overview

Product Details

Manufactured strictly in accordance with Holset and Cummins original design drawings, dimensional tolerances and standardized production processes, Assy No.5355321 features unified structural layout, installation dimensions and boost pressure calibration parameters with interchange counterparts, supporting direct bolt-on installation without any modification. It effectively resolves common turbo malfunctions including insufficient climbing power, heavy black smoke, abnormal oil consumption and obvious turbo lag caused by aging and damage.The rotor assembly undergoes ultra-precise high-speed dynamic balance testing; all finished turbochargers pass air tightness inspection, boost pressure calibration and comprehensive appearance quality verification before delivery, capable of stable long-term operation under severe working conditions: continuous heavy load, frequent start-stop and high exhaust temperature environment of construction machinery.

Product Advantages

High-strength Materials & Robust Structure

Turbine wheel and compressor impeller adopt high-temperature resistant nickel-based alloy, featuring excellent thermal fatigue resistance to adapt to high exhaust temperature working conditions of large-displacement industrial diesel engines
Advanced floating oil film bearing system ensures stable rotor rotation, effectively prevents oil leakage faults, and withstands long-term heavy load impact and frequent start-stop cycles of engineering equipment
Built-in pneumatic wastegate structure adjusts intake boost pressure in real time accurately, avoids engine damage caused by overboost, and delivers sensitive low-speed power response

OEM Grade Precision Manufacturing

Overall outline, mounting hole layout and boost parameters are fully consistent with original factory components, plug-and-play installation without pipeline modification
High-precision dynamically balanced rotor reduces running vibration and noise, greatly extending the overall service life of the turbocharger
Multi-channel air tightness testing eliminates oil seepage, compressor surge and abnormal exhaust noise troubles
