Abstract
A method of modifying an existing gearbox wherein the existing gearbox has an input shaft connected to drive a first idler gear. The first idler gear engages a gear for driving a fuel pump at a first speed. There is a first distance between a center point of the first idler gear and the fuel pump gear. The step includes replacing the first idler gear with a replacement first idler gear having a distinct number of teeth, and replacing the fuel pump gear with a replacement fuel pump gear having a distinct number of teeth such that a speed output to the fuel pump is distinct from the speed at the fuel pump with the existing gearbox. A gearbox is also disclosed.
