Window Motor Modification - Is it legal?

[DavidGitz]

Team 2219 is considering using a swerve drive this year, but our problem is where to mount the encoder on our steering motor. We are using the Window motors and right now our design does not leave any room for the encoder.

Our thought is that we can cut away part of the plastic housing on the Window Motor transmission where the other side of the output shaft is, drill a small hole, tap it and put in an assembly to mount the encoder.

Quoting the rules:

<R54> So that the maximum power level of every ROBOT is the same, motors and servos used on the ROBOT shall not be modified in any way
A. The mounting brackets and/or output shaft/interface of the motors may be modified to facilitate the physical connection of the motor to the ROBOT and actuated part.

My question is, does the opposite side of the output shaft still constitute an interface? Does modifying the plastic housing where the output shaft sits result in a violation of this rule? I will be posting this on the Q&A tomorrow but wanted to get your opinions first.

Thanks!
