Weichai 1002599734 Turbocharger Assembly

This turbocharger assembly utilizes the GTA42 compressor and turbine frame configuration, calibrated specifically for the Weichai P12 series 12.5L displacement diesel engines. The unit integrates a forged milled compressor wheel, high-flow turbine wheel, and precision-balanced rotating assembly to deliver optimal boost response across the 1100-1900 RPM operating range. The bearing housing incorporates a full-floating journal bearing system with thrust bearing control, designed for sustained operation at turbine inlet temperatures up to 850°C. Actuation is managed via a pneumatic wastegate actuator or electronic VGT actuator depending on specific engine calibration code. Mounting flange geometry and oil/coolant port interfaces conform to Weichai OEM installation drawing standards for direct bolt-on replacement.
