propeller torque

[maurice]

Would you please verify the proper torque for the prop bolts on a 7ECA O-235?? 25 foot pounds stands out in my mind, but I can't find a reference. Thanks.

Citabria Service Manual (Reissue 5-1-79) says: "Torque prop bolts to 23-25 ft.lbs."

And be sure, you install the prop in the position the text says, the figure 7-3 in the manual is wrong! I have had it once installed the wrong way and had severe vibration.
