The balk ring got its name by the tension it has with the gear plate. This is what Mac is referring to. The tension is important for the shift action. When you let off the throttle above governor on speed, that tension is what allows the balk ring to move out of the way of the pawl so it to go on in and engage one of the six gear plate notches. It has to be in there just like the photo shows. If the pawl wasn't between the two protrusions of the balk ring, it could never engage the gear plate and lock the sun gear.
