Keep in mind that this is a prototype.
The part where you grab onto will have a different dimension than the part going through the brush hood so it will be easy to hold onto. This one currently has a 3 1/2 inch long handle.
I have not thought about that with the other piece. Usually when you put it through the motor if it isn't aligned then you have other problems. This part will not be for aligning the bushings or bearings. It will be for checking to make sure that everything is in the proper position. I don't have this part yet, thus the reason for no picture.
Here is a picture of the entire tool. It isn't the greatest picture but it will give you an idea.
