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 steps for assembling a two-stage gearbox for specific motors.
MAXPlanetary Gearboxes purchased before 11/14/2022 will need to install the included spacer to use a CIM, miniCIM, or Falcon 500.
