FULL SPEED AHEAD !

The gearbox design has been quite a challenge : I have a lot of mechanical power to transmit (4.8kW) with a high speed on one side and high torque on the other. Not to mention that the gearbox had to be as compact as possible to fit in the tank. I used roller chains instead of gears to make it easier to assemble run and maintain, as is it my first gearbox project.

OUTCOME

The Mk1 Gearbox has never been tested. I figured I would obviously run to dangerous problems without tensioner sprockets. It would also to be difficult in maintainance to disconnect the gearbox output from the rest of transmission.
See you at the "Gearbox Mk2" post ;) !!
