How to install a shaft-mounted gearbox with a keyway?
To install a shaft-mounted gearbox onto the shaft, drive a screw into the centre hole thread on the shaft end and then tighten the nut on the screw as pictures shows. Before installation, grease should be applied to the shaft to ease future removal.
The screw diameter must be smaller than the diameter of the tapped hole of the thrust plate and equivalent to the diameter of the tapped hole of the shaft end.
