Perhaps you guys are using the wrong grade shear pins. I bought a stash of genuine GI pins from Gene Patano in CO. I can drag my truck with locked brakes easily with the correct aluminum shear pin. If the holes in the shaft or yoke are wallowed out, it will shear the pin as well. I have loaded it to the point of beaking them too so they are the fusible link. The ones Memphis sells I don't think are right. The GI ones don't have a head and require a cotter pin at each end. I once again refer everyone to FM 20-22 (in the tm section) for a good read on everything recovery. With the proper calculations and use of snatch blocks, you will never break that shear pin.
