Weichai BY612630110320Y Turbocharger Assembly

The BY612630110320Y turbocharger is designed for Weichai WD615 11.6L and 12.5L diesel engines. It features a wastegate-actuated turbine housing for precise boost control across the operating range. The compressor wheel and turbine wheel are balanced to ISO 1940 G2.5 standards to minimize vibration at speeds exceeding 100,000 RPM. The bearing housing integrates water-cooling ports for thermal management under sustained high-load conditions. This unit serves as a direct replacement for Weichai part number 612630110320Y. It utilizes a 4-bolt turbine inlet flange and V-band compressor outlet configuration typical of the Holset HX55 frame size. Oil feed and drain ports conform to Weichai WD615 block machining specifications. The assembly includes the CHRA (Center Housing Rotating Assembly) and actuator calibrated to Weichai ECU boost maps.
