Re: Gearbox Modification
Thanks everyone for your help: LH Machinist, Coffeeism, slijin, Joe.Quirkand WileyB-J. Much appreciated!
I think the intent is to prevent modifications to motors. The gearbox is integral to the Window "Motor" and Snow Blower "Motor" as it can't be used without the gearbox. I think modification of the shaft is within the spirit of the rules. I'll proceed with making the new shaft while maintaining ability to revert to unmodified design.
I went to the Q&A section of FRC. I posted this question but am not sure if I did it properly.
Here are the relevant manual statements and Q&A's if found:
---------------------
The intent of this rule is to maintain the maximum power level for each ROBOT, yet still allow teams to modify mounting tabs and the like, not to gain a weight reduction by potentially compromising the structural integrity of any motor. The integral mechanical and electrical system of the motor is not to be modified.
Note that for the Window motors, the gearbox is considered integral to the motor, thus the motor may not be used without the gearbox.

Q233 Q. We have a AndyMark am-0914/pg71 gearmotor assembly which was supplied to us in our KOP and it is not listed on the table in R32 but it is listed in the competition manual, section 4 2013 Technical resourses. Are we missing something in the table or is this an error? (1 Follow-Up Questions)
A. [R32] regulates motors, not motor/gearbox assemblies (except where the gearbox is considered integral to the motor, see [R33]).
--------------------
Q148 Q. If we remove the gear boxes from motor part number 262100-3030 or 262100-4040 and do not use the motors is it ok to use the gear boxes with other motors
A. There are no Rules prohibiting this.
-----------------------
Q250 Q. Table 4-1 under the Andymark PG entry only shows am-2161 and am-2194, not am-0914 which was supplied in the Kit of Parts both in 2012 and this year. Is this a legal motor?
A. The am-0914, as supplied in the KOP, is not a motor, it is an assembly of a motor (am-2161) and a gearbox.
