A gear assembly for retrofitting a rotatable turret assembly having pre-existing mounting brackets. A gear assembly housing is cut so that it fits onto the pre-existing housing mounting brackets. An operator controlled hand crank is connected to an input shaft. The input shaft extends through the gear assembly housing and includes an input shaft gear that meshes with a drive shaft gear. The size of the drive shaft gear has been maximized so that it fits within the gear housing that has been mounted on the pre-existing mounting brackets. A drive shaft is connected to the drive shaft gear and extends through the gear housing. A sprocket is connected to the end of the drive shaft gear. The sprocket is mechanically linked to the turret assembly for controlling the rotation of the turret assembly. In a preferred embodiment, the turret assembly is mounted to a HMMWV. Also, in a preferred embodiment the gear housing is fabricated from 6061 billet aluminum and includes cuts to allow for a maximum sized drive shaft gear.
