Sinotruk 1004055533 Turbocharger Assembly

The 1004055533 turbocharger assembly is engineered for Sinotruk HOWO heavy-duty commercial vehicles. It utilizes a turbine housing with integrated wastegate actuator for precise boost control across the engine operating range. The compressor wheel and turbine wheel are balanced to ISO standards for high-speed rotational stability. The center housing rotating assembly (CHRA) features full-floating journal bearings and thrust bearing system lubricated by engine oil supply. This unit serves as a direct OEM replacement for Sinotruk HOWO T7H, T5G, A7, and Sitrak series trucks equipped with Weichai WP10, WP12, WP13 or Sinotruk MC11, WD615 engine platforms. Installation requires verification of flange orientation, oil feed and drain port alignment, and actuator calibration. Torque specifications for mounting hardware must follow engine manufacturer service manual procedures.
