Hitachi 2036570 Drive Sprocket Assembly

This drive sprocket is engineered as a direct replacement for Hitachi mini excavator models FH22.2, FH30-2, and FH35-2, as well as compatible EX and ZX series machines. Manufactured from forged or cast 40Mn alloy steel, the sprocket undergoes precision machining and heat treatment to achieve a surface hardness of HRC 50 to 60, ensuring high wear resistance against track bushings and pins in abrasive operating conditions. The sprocket features 22 teeth configured for a 52.5 mm track pitch, matching the standard undercarriage geometry of the target models. It serves as a direct interchange for Hitachi OEM part numbers 2036570 and 2039666. Designed for heavy-duty construction applications, the component restores proper track tension and drive engagement, minimizing premature track and roller wear.
