Weichai 610800110180M1 Turbocharger Assembly

The 610800110180M1 is a variable geometry turbocharger (VGT) assembly designed for Weichai WP12 and WP13 11.6L to 12.5L displacement diesel engines. It integrates a pneumatic or electronic actuator for precise boost pressure management across the engine operating map. The unit features a forged milled compressor wheel and high-temperature alloy turbine wheel housed within a cast iron turbine housing rated for sustained exhaust gas temperatures exceeding 850°C. The rotating assembly is supported by a full-floating journal bearing system with thrust bearing, lubricated and cooled by engine oil supply. This turbocharger is calibrated to match the specific compressor map and turbine A/R ratio requirements of the WP12/WP13 engine family for Euro III to Euro VI emission compliance. The cartridge (CHRA) is balanced to ISO 1940-1 G2.5 standards. The compressor cover includes a port for pressure ratio control solenoid connection. The turbine housing utilizes a V-band clamp or flanged connection for exhaust manifold mounting. Oil inlet typically M18x1.5 or M22x1.5 thread; oil outlet flanged with gasket surface. Coolant ports present on bearing housing for water-cooled applications. This assembly replaces the complete turbocharger unit; no separate actuator calibration required if supplied pre-set.
