Today I ran over some rope and the auger on my st224 pulled it in and jammed. One of the shear bolts broke and I had to remove the other to unwind the rope from the auger(both sides). Now I can't find the holes in the center of the auger shaft to push the new shear pins into. I think the rope may have wedged the shafts apart from both sides of the gearcase because I can see a gap where it comes out of both sides of the gearcase. I can turn the input shaft from the impeller freely by hand and it doesn't seem to engage with the auger shaft. Have the shear bolts failed to protect the gears, and if so, is there a video or tutorial somewhere showing how to replace the gears (if I can find replacements)?
