Tony, I have no idea where I heard this or even if it is just something I imagined but, I seem to recall something about after the bottom end is assembled, loosen the main cap bolts, insert as this a feeler guage as possible between the cap and the piston rod next to it to keep the main cap from trying to rotate as the bolts were re-tightened.
keep em honest on the other thread. At least nobody has suggested velcro!
