Re: Weird Behavior - Vex Pro Ball Shifters
We have had the problem of keeping the shifter engaged. We learned it is based off of the nut on the cylinder as well as stand off length.
If you open up the shifter and look at the shaft without the gear or balls in. Pull on the coupler all the way back to see how far it pulls on it.
Pulling to far will ha e the problem of not disengaging to close will ethier break the coupler or pull the cylinder a bit and release early. We found at the stand off length of 1(5/8) is good with an 1/8 inch mounting plate instead of .09.
Hope this helps.
