We removed the pins you refer to for testing a year or two ago. We never did use them in competition. Older rules precluded this but I don't know the exact current ruling on this. (There is a rule about altering integral gear trains but I think there is a comment somewhere in the current rules excluding the pins. Please check as I don't want to accidentally lead you astray.)

I don't have a video handy but if you start to take things apart there are a couple things that might be good to be aware of.

1) There is a very small magnet/spacer in some motors that rests on top of the rotating sprocket "shaft" when you first take things apart. I did not even notice it the first time. I don't know if this is on all generations of the motor.
2) There is a one way spring clip that holds the rest of the mechanism in place. It is difficult to remove this without some damage to it. Take your time. It seemed to be okay if we put in back on with only slight damage.
3) Once you get the clip off there is a piece holding three pins in a vertical direction. That piece has a spring behind it. It is easy to disassemble but don't let the spring eject and loose it.

Incidentally, it is still not easy to turn. Most people must have a strong grip or get some leverage to do it. If you are raising an "arm" connected to the motor, you may have the leverage you need.

There are always alternatives but it is doable.
