The part numbered 423-22-31480 is a differential spider gear component that operates in the axle gear assembly of Komatsu WA380-6 and WA430-6 loader models. Within the system (also tracked in the 4232231480 format), this gear element plays a critical role in balancing torque transmission and proportioning the power delivered to the wheels. During gear replacements, meticulously inspecting the pinion and pinion bearing fit directly affects the lifespan of the drivetrain.
Compatibility and Assembly Notes
During axle and differential overhauls, assembly clearances (backlash) must be adjusted millimetrically with the aid of a gauge. To prevent any potential mismatch, it is recommended to compare the tooth profile of the removed old part and thoroughly clean out any debris inside the housing.
How can you verify uncertainties regarding part compatibility during your WA380-6 or WA430-6 transmission and differential overhaul along with your machine's serial number?
