Standing out with its metallic structure and gear profile, this differential planetary gear with part code 421-23-32530 is manufactured to provide high strength in the powertrain systems of heavy-duty construction machinery. Also known alternatively as 4212332530, this component is safely preferred in Komatsu WA430-5, WA470-6, and WA470-8 loader series.
In differential systems exposed to high torque and intense friction during operation, precise gear alignment directly determines the lifespan of the powertrain components. During replacement, inspecting the wear conditions of the spider journals, axle shafts, and other surrounding gear groups extends the service life of the newly installed part and supports quiet system operation.
To confirm part compatibility in your powertrain, you can compare the number on the removed old part with the 421-23-32530 reference.
