Abstract: A method for timing a stage 1 pinion gear and a stage 2 helical gear includes providing a stage 1 pinion gear including a pinion apex and a stage 2 helical gear including a plurality of stage 2 helical teeth, a center bore, and a stage 2 plane. The method also includes providing a spanner wrench and a pinion stop. The method also includes placing the spanner wrench on the stage 2 helical gear, inserting a shaft of the stage 1 pinion gear into the center bore such that the spanner wrench is positioned around the stage 1 pinion gear, securing the pinion stop to the stage 2 helical gear, and rotating the spanner wrench to engage the pinion stop with the spanner wrench.
