From time to time the cotter pins in the upper clean grain chain drive sprocket would shear. I remember the fan would fill with corn and run out the sides. We never broke a fan up but if the new ones are poorly made it might break them up. Maybe you should try a used fan from a salvage yard, the old stuff was just built better. Those fans should not break that easily tho, they just don't turn that fast.   [Reply]   [No Email]
