Ultimate 2.0 "wheels" not aligned and tank track rubbing on beam

#1

I bought the ultimate 2.0 kit and wanted to start with the detecting robot, so I am using the assembly video here but it seems to mirror the instructions for the robot arm tank in the actual instruction book. The issue I am running into is that the white 90 teeth “wheels” are not aligned on each side. One on each side connected to a motor has a 4mm shaft connector in between the motor and the wheel. The other ones not connected to the motors have 2x 4x7x3 plastic rings which makes that wheel stick out a bit further than the ones on the motors. When I place the tank track on the wheels, it seems to rub and not sit right on the wheels with the motors, so I feel like they need to be pushed out farther, but the instructions don’t really mention this. Does it need spacers, or do I just leave a bigger gap between th shaft connector and the motor mount?

Hi mike208,

You can adjust the wheels with motor. The gap between the shaft connector and the motor mount is adjustable.
