Q. I am trying to understand can you change the ratio of the gears, if yes how do you change the ratios?

A. Hi Brendon. Thank you for your question. The ratio can be changed by having different combinations of the gearwheels as they interconnect and by having fewer in the gear chain. The data sheet illustrates this.
