This is a 12-volt DC electric motor designed to drive hydraulic pumps on liftgates and snow plows. It spins clockwise and has a 9-spline shaft that mates with common Fenner-Stone and other pump units. You would replace it when the original motor fails due to water intrusion, worn brushes, or bearing seizure, restoring reliable lifting and spreading operation.
Verify your original motor’s OEM part number before ordering to ensure correct shaft, rotation, and mounting dimensions. This aftermarket replacement covers dozens of models, but always cross-check with your equipment manual or dealer.
