We don't use 3/4" bore cylinders at 60 psi, but historically have used 9/16" bore at 40-60 psi.

We used 7/16" in 2012, but that was a single CIM per setup and had no initial reduction.

We use a standard #4-40, have never broken one.

We limit the stroked so that fully extended or fully retracted the dog is not loaded into the face. Of course when it's shifting if the dog gear hits the other gear tooth to tooth it will experience load while one rotates, but other than that we never actually load the gears.

I think the combination of shimming and lower force is what has caused us to never break a screw.
