    Default Torque for Prop and Prop Spacer Bolts - O-235

    Can anyone give me the torque for the prop bolts and shorter bolts fastening the prop spacer to the crankshaft flange? Also, safety wire diameter for the shorter bolts. Engine is O-235, prop is McCauley Aluminum prop.

    Thanks in advance!!

    Here is the approved data. Bottom of page 4. Safety wire is supposed to be largest size you can fit into the hole. Usually .041 for propellers.

    The prop TCDS says to install per McCauley drawing C-1211. Suggest you find a copy of the drawing, sorry I don’t have a copy.
