Shale or oversize coal combined with the wrong shear pin in the drive mechanism.

Thanks but it ran for years with the same rice coal and shear pin now he has 1 shear pin left. any other reason ? Its un pridictable it will run months with out breaking than bam . I have welded it together maney times and I am a pro welder for 45 years . It doesn't break in the same spot.

Worn auger flights, worn gooseneck bushing, worn worm bushing...all of these can lead to grinding coal and sheared pins. The shear pin should always break before the auger, something isn't right.

Do you use two pipes with a coupling in between? If so, check inside the coupling for a rusted-through pipe or any gap between the two pipes where they butt. Otherwise, check the things mentioned in this posting.
