# MAXPlanetary Gearbox Assembly

The REV Robotics MAXPlanetary comes with the gearbox deconstructed, allowing for the user to modify the total reduction needed for the application. Each cartridge is pre-assembled and lubricated, allowing for easier customization. Below are links to the steps for assembling a two-stage gearbox for specific motors.
