The track is too tight, did I do something wrong while assemble the Ranger robot

I want to double check some points to make sure if you have assembled it correctly.

1. The 6 wheels for the ranger are all in the same size. Please don’t use the larger wheel (92T wheel) by mistake.
   

2. Please make sure the wheels, motors are assembled to the correct holes according to the user manual.
   
   

3. When assemble the track to the wheels, please make sure the wheels go into the slots on the tracks. After assembled it, please rotate the tracks several times by hand and see if it still too tight.

Hi,
I figured that it is helpful to use a second nut to fix the screws, while keeping the wheel easily turning. it was necessary to shorten the plastic distance piece.
