When sourcing Shacman engines (primarily Weichai or Cummins series), the price is heavily influenced by the Horsepower (HP), ranging from 270HP to 550HP, and the Emission Standard (Euro II to Euro VI). You must verify the Displacement (e.g., 9.7L, 11.6L, or 12L) and the Torque ratings to ensure the engine matches your specific truck model (such as F2000, F3000, or X3000). Always confirm if the price includes the Turbocharger, Alternator, and Starter Motor, as these 'complete' assemblies vary significantly in cost compared to a 'bare' engine block.
