Designed with a circular form and a special fitting groove in the center, it adapts to the operating dynamics of heavy-duty powertrain systems. Having the part number 423-22-31670 or written continuously as 4232231670, this 423-22-31670 Komatsu Differential Pinion Gear Shim operates in the axle and differential assemblies of WA380-6, WA430-6, and GD535-5 machines.
During differential overhaul processes, closely inspecting the wear condition of the pinion gear shim and checking the tabbed surfaces is crucial for the health of the powertrain. Adjusting gear backlash according to manufacturer tolerances during assembly and replacing it alongside surrounding shims directly supports its working lifespan.
You can add this component with code 423-22-31670 to your cart to maintain your machine's powertrain performance and complete your differential maintenance.
