I've been running a 9250 combine for 5 years and have had problems shearing the bolt that runs the swing unloader from day 1 on. I have to play with shutting the drags off and on while unloading in order to not shear the bolt. I've checked the timing on the augers and its correct. I've replace the top elbow gearbox as it seized up this year already really hoping the problem is solved only to shear another bolt on the very next hoper. The bottom gear box(original) seems to turn easy with fresh oil every year it looks to be 100%. I combine beside 5 other 9250s and they hardly ever shear a bolt. I do combine a lot of lentils and I do realize the augers gum up with dirt but Y am I shearing and the others don't. I am a professional at putting in new shear bolts bolts!!! Frustrating. I even got the dealership out we went over everything and cant find nothing.

There was a PIP on the early 50 series that changed the single lug coupler on the folding auger to a dual lug coupler. Also there was a software update that made the engagement slightly softer. If this has not been done it would likely help your situation.
