That brass clicker has scared you now. Hahah! I have no idea on torque specs for the shim stack retainer bolt, but I would be taking a guess that a bit of red locktite, and a bit more than finger tight would be in order. More like firm
Haha! You don't want it coming undone and floating around your internals.
Also if you've using a bit torque wrench it probably won't be accurate. Most are only really accurate in the middle of their specified ranges so coming out to the ends introduces variance. I have a 1/2" drive kincrome for the big jobs which I rarely use, and a small GearWrench 1/4" drive which was purchased for doing 4T top end valve gear. Its ace for the smaller bolts everywhere! Was a pricey lil wrench though! (
