Mounting a new WW151H prop on my IO-320 RV9A. It came with new studs and castellated nuts, with roll pins to secure the nuts to the studs. The manual says "installed the studs, torque to 47ft-lbs, then safety wire w/ .036 wire". Or something to that effect.
Problem is installing the studs in the crank, then torquing the nuts to the required 47ft-lbs does not engage enough stud to uncover the holes for the rollpins. See photo. Also the rollpins do not allow for safety wiring the nuts....
So I'd assume you install the nuts to the studs, install the rollpins, then torque the studs into the crank.... But wanted to check first here (since its Sunday) and then call WW tomorrow if necessary....
Help appreciated. ed
