Surveyed all eight CP LLCV stems for loctite blue 242 application. CPs 2, 4, 5 now have loctite and were re-zeroed (CP5 has broader range). The others' stems were so tight that I couldn't loosen, so I assumed they don't need loctite.

NOTE:  CP 2 & 5 stems were starting to unthread from the actuator coupling nut again, prior to loctite application.
