Yeah, there's the rub. The question, which somebody who actually has a Q&A account should ask, is: "In the process of performing a legal modification to a CIM motor, it may become necessary to take it apart and put it back together. Is it legal to do so, provided that nothing else is done besides removing a piece, legally modifying it (e.g., adding a mounting hole), and putting it back in?"
