Hello everybody,
I have different informations regarding the correct torque of the MK25(Evo) seat retainer:
In the older Frogkick manual for the MK20/MK25, Scubapro recommends to tighten the screw to a torque of 15NM or 130 in lbs.
On the (round) seat retainer of my old MK20, there's also the imprint "TORQUE 15-17 NEWTON x m" (picture).
In a (also from Frogkick) schematic of the MK25 AF, rev D, the torque of the new hex seat retainer is declared as 30NM or 266 in lbs.
What do you think? I don't know if I'm correct, but to my eyes, the technical difference between the old round and the new hex seat retainer seems to be rather the outer form, but less it's function as a screw. I't just an impression, but I think that 30NM would be far to high.
So, what do you do?
