A ready-to-use DeWalt 3-speed transmission mated to an 18v DeWalt motor with integrated output shaft. Fully assembled!
The Dewut Geared Motor converts a DeWalt 397892 series 3-speed transmission and the DeWalt 396505 series 12, 14.4, or 18 volt motor into a finished, ready-to-use gearmotor with 3 selectable speeds, a 1/2″ keyed output shaft riding in dual ball bearings, and adjustable torque clutch setting using the existing gearbox clutch.
DeWalt transmissions and motors have been staples in robotic drivetrains for many years. But like any integrated consumer product, the gearbox itself is oddly shaped, not attached to the motor, and its output shaft is a custom irregular polygon! What could you possibly do? We take care of the hard part for you with this gearbox kit.
