Holset VG1097110301 Turbocharger Assembly

The VG1097110301 is a Holset HX55/HX60 frame size turbocharger assembly designed for Weichai WD615, WD618, WP10, and WP12 series diesel engines ranging from 9.7L to 12.5L displacement. It features a cast iron turbine housing with integrated wastegate actuator for boost control, a forged milled compressor wheel, and a fully floating bearing system lubricated by engine oil. This unit serves as the original equipment turbocharger for Sinotruk HOWO, HOWO A7, HOWO 7, and HOWO NX series heavy-duty trucks meeting Euro II through Euro IV emission standards. The turbine housing utilizes a T4 flange configuration with a 4-bolt outlet. The compressor cover incorporates a 4-inch inlet and 3.5-inch outlet. Critical clearances and rotor balance meet OEM specifications for high-altitude and high-load operating conditions typical in construction machinery and long-haul transport applications. Cross-reference interchange includes Sinotruk OEM part number VG1097110301 and Holset service number 202V09100-7858. Installation requires new gaskets, oil feed line inspection, and prime lubrication before initial start-up to prevent bearing failure.
