How does the 4wd work?

The Transfer box and front hubs work in combination.

2WD
The Transfer box puts the power to the rear prop in 2wd and disconnects the front prop from the transmission.
The front hubs disconnect the wheels from the drive to stop the props turning as the front wheels turn.

4WD
The transfer box connects both the front and rear props together and both turn with the transmission.
The front hubs connect the wheels to the drive so everything is connected together.

There is a simple sliding collar (red) that locks the front shaft (blue) to the twirling gubbins inside the transfer box.

The drive is via a hy-vo chain from the top flange, all the sectioned gubbins is an epycyclic reduction gear to give low range.



If it suddenly breaks, go back to the last thing that you did before it broke and start looking there :)
