Kit GearBox

Hey I’m new to the first competition.
My team is having problems with the gear box. We need to know where we can find the special collar that attaches to the hex output shaft for the output sprocket and where we can find it. I’m getting all this from the 2005 chassis video.
We really need help.

You can find the plans on page 66 of the tranmission manual located at

It is very simple to make – simply take a piece of 3/4" PVC pipe, cut it to the appropriate length, and cut a notch using a round file, dremel tool, nibbler, or pocket knife.
