For the health of transmission systems in heavy machinery running gear and differentials, the component with part number 419-22-21751 plays a critical role. This part ensures the protection of internal differential clearances and friction surfaces in both standard productions and variant series.
Confirming the original part code during differential and transmission maintenance processes is extremely important for the machine's operating life. During part replacement, the wear condition of the differential gears should be checked and evaluated together with compatible transmission, final drive, and differential parts. During maintenance, the reference number without spaces in the 4192221751 format can also be used for catalog matching.
When performing a differential overhaul on wheel loaders operating under heavy site conditions, selecting the correct washer directly affects the stability of torque transmission. Accordingly, confirm the correct part code 419-22-21751 for your WA320-3 and WA320-3CS series machines and place your order.
