Designed to maintain hydraulic system performance in the Komatsu excavator series, this component with part number 706-7G-41720 is a critical transmission element that regulates rotor movement within the swing motor (also formatted as 7067G41720). It ensures full compatibility with the hydraulic slewing mechanisms of PC200-8, PC220-8, PC270-8, PC240-8, PC290-8, and PC210-8 series machines.
During the replacement process of rotating group components subject to wear, cleaning the housing surfaces after removing the old plate and clearing the hydraulic lines from foreign particles is important for long-lasting use. Checking rotor tolerances and surface contacts during installation helps prevent potential pressure losses.
To ensure the proper operation of your hydraulic swing group and to confirm part compatibility, it is recommended to compare your machine's full serial number with the numbers on your current pump or motor tag.
