Important Fitment Note

LG top loader washing machines may use similar-looking gearboxes with different shafts, splines, mounting plates and clutch mechanisms. Before ordering, confirm the complete appliance model and compare the 4265EY1003A or GCT131 reference, shaft length, shaft diameter, spline pattern, threaded section, pulley, mounting holes and brake-lever arrangement with the original gearbox.

The gearbox hub nut and other installation hardware are not included unless specifically stated. Inspect the hub nut, inner basket hub, motor pulley, drive belt, drain actuator and mounting bolts during installation.

Replacing the gearbox requires substantial disassembly of the washing machine. Correct tightening and alignment are essential to prevent basket movement, leaks and premature gearbox failure.
