Tamiya 4-Speed Crank Axle Gear Box - Product Description

 

The Tamiya 4-speed crank-axle gearbox has four possible gear ratios, including the highest gear ratio of Tamiya’s gearbox series, 5402:1, as well as 126:1, 441:1, and 1543:1. This gearbox also features a worm gear, which locks the output shaft when the motor is not turning. A clutch gear prevents the gearbox from destroying itself in case the output shaft gets stuck. The kit comes with all parts necessary to build the gearbox in any of the four possible configurations.

 

The picture below shows the contents of the clear version of the kit, which is no longer available. The components are the same for this version of the kit, except the gearbox housing pieces are solid gray.
