Re: Shifting Gearboxes
We always use a double solenoid, and we also use plumb both shifters to one valve so they throw at the same time. Please remember to USE PNEUMATICS TO SHIFT. Servo shifting is pure garbage and wont work under the the slightest pressure against the side of a dog, such as when pushing.
We usually start in low gear, and use high gear when we want to go really fast.
We have never tried using ball shifters, but since we have familiarity with the dog shifting style used in AndyMark gearboxes, and it has proved reliable so far as a shifting method, that probably won't change. Dog shifting is proven and tested, but ball shifters have been generally well reviewed as well, though they may be harder to implement in a custom gearbox.
