You need to do the following steps:
- Select and open the kart you want to work with
- Open the Parts tab
- Select the part that you want to replace
- Click on the button Replace
NOTE: You can't replace EMPTY part, because this part represents the kart itself.
The system will create a task for the part replacement. You will see this dialog:
Enter the time that you spent on the part replacement and click Ok.
After that you will have old part removed from kart and the new one attached to the kart.
