This is a second entry for today to explain what I did. In the first picture you can see the plans have you mount center lower two bolts that hold the Dyna Focal engine mount to the airplane reversed from all the others. This is because the other end of the bolt is sandwiched between the two floor layers of the cabin and there is only a ¾” hole to get access that end. Now when I tried to do this I could not figure out how the heck one could get the cotter pin in the castled nut, the access hole is just big enough to get a box end wrench inside.
I thought that there must be a way to get the bolt in with the threads sticking out, this would be better in that the torque can be set from the nut, really can’t accurately set the torque from the bolt side. What I finally came up with is floss. The bolt is drilled at the end for the cotter pin to keep the nut from vibrating off. I put some floss through this hole then pulled the floss through the mount hole. By pulling the floss and moving the bolt a little with my finger in the access hole I was able to install it the proper direction.
I finished up by setting the torque and installing the cotter pins. Now mount is now ready for the engine!
This is what the drawing looks like
Floss did the trick
Not sure how one would set the cotter pin the way the plans call for it.
