3/4 turn more after being torqued to spec - that seems like a lot. I wonder if the loader frame isn't tight and you are squeezing it in place with that extra force.
I was not looking for advice, (your not talking to a dummy, I was an electromechanical engineer for 25 years) I opened the thread to give others a heads up so they could check there's to make sure all is well, that's it that's all..
Everything looks perfect. To me, the spec wasn't very tight. Those are some rugged pieces of steel, bending it would take more than a little leverage.
What was spec for them? My manual has a chart listing bolt specs for everything that doesn't show individual specs. It just goes by bolt size, thread, and grade. I figured it was industry standard specs for bolts, but I never researched. You're right about the rugged steel and I remembered that after reading your reply.
