Weichai 1005201993 Turbocharger Assembly

Weichai 1005201993 is an OEM turbocharger assembly designed for the Weichai WP13H series heavy-duty diesel engines compliant with China VI emission standards. The unit utilizes a BorgWarner B3G frame featuring electronically controlled variable geometry turbine (VGT) technology. This configuration provides precise boost control across the operating range, enabling high torque at low speeds and reduced particulate emissions. The assembly integrates the compressor housing, turbine housing, and center housing rotating assembly (CHRA) with water-cooled bearing housing. It replaces Weichai part numbers 1005201993 and 1002933930. Cross-references include BorgWarner service part numbers 13879880137 and 1002375390. Installation requires verification of engine serial number and emission calibration version due to variant-specific actuator calibration and flange orientations.
