What is proper torque for prop bolts (McCauley 84/43 and Lycoming 0-360) please?
The 1P235 prop or 1A200 run on 0360 engines use 1/2 '' bolts Mc cauley recommends torquing to 55 to 65 ft pounds
Here are the McCauley torques from their SERVICE BULLETIN 227B

When a prang seems inevitable, endeavor to strike the softest, cheapest object in the vicinity, as slowly and gently as possible.— advice given to RAF pilots during W.W.II.
Thank you. My 93-year-old flying buddy today asked, "Do you suppose you can find out on the Internet what's the torque?" When I tell Tommy tomorrow he will just shake his head. He was cutting logs with crosscut saw and on the river drives before he went off with his three brothers to war. Like myself, we marvel at the miracle of the Internet and the generosity of everyone here.
I wouldn't be toooo quick to go 30 ft -lbs on a 3/8th bolt though...
