Used in the powertrain systems of WA320-3, WA320-5, WA320-6, WA380-6, and WA270-7 series loaders, this part supports the stable operation of the differential system under load. Bearing the part number 417-22-22810 or 4172222810, this component provides shaft housing for the planetary gears exposed to high torque and rotational forces. For a proper fit, the number and housing diameters on the removed old component must be meticulously compared. During replacement, the gear clearances in the differential housing and the condition of the bearing surfaces must be checked.
When replacing bearings in powertrain systems, choosing options matching original part numbers instead of aftermarket products directly extends component lifespan. Using bearing insertion tools during assembly guarantees that the component seats axially in its housing and prevents premature wear. You can check the current shaft and gear dimensions to confirm which part number you need for the differential overhaul of your WA320-3 series or WA380-6 model heavy equipment.
