## Description

Turn your 19.2:1 ratio Yellow Jacket Planetary Gear Motor into a speed demon with this 1:1 Ratio Conversion Kit! It dramatically bumps up the output speed from 312 RPM to almost 6000 RPM.

While motors with a 19.2:1 ratio provide versatile torque for a variety of mechanisms, some applications—like shooting and launching assemblies—benefit most from high-speed motors. This Kit saves you another trip to the motor store, allowing you to choose the speed you want out of your existing motor.

As you’d expect from its name, a Yellow Jacket Planetary Gear Motor is normally driven by its planetary gearbox, which is itself driven by the motor’s pinion gear. This Kit locks the pinion gear to the output shaft to create a 1:1 ratio.

This Kit includes eight Thread-Locking M3 Flat Head T10 Torx-Drive Screws and a T10 Torx key alongside its conversion plate. These provisions allow for a foolproof installation, even if a screw is lost or damaged.
