I'll leave the rest as an exercise to the reader.

If you mean replacing the bolts holding the motor together with different ones... I would think this is a violation of R30:

The integral mechanical and electrical system of any motor must not be modified.

Those bolts are pretty integral to the mechanical system of the robot... without them the whole thing falls apart and stops working!
