Description
This automatic locking hub, Fig. 7, when placed in four wheel drive, directs power to the front wheels. The front axle turns the axle shaft, activating
the tri-cam mechanism, which then moves the drive gear outward into engagement with the ring gear.
When two wheel drive is selected, disengagement is accomplished by the reverse movement of the wheels, which causes the drive gear and tri-cam to
rotate to the disengaged position, moving the drive gear out of mesh with the ring gear.
