Happy new year to all. I have been more or less lurking on this forum for some time, picking up all kinds of helpful fixes and mods for the BX23. One thing that caught my attention was that some folks are having trouble specifically with the 2750 snowblower shear pin replacement and this probably applies to other models as well. It has been suggested to use grade 1 (no marks on the bolt head) bolts as shear pins and while they do provide the protection needed, they tend to cause replacement problems. Because these bolts are soft, they do no usually snap cleanly when a shearing shock is applied to them. Either they slightly bend (eventually wallowing the shaft hole) or they shear but instead of a clean snap, the ends of the bolt left in the shaft are sort of smeared out, causing some difficulty to get them punched out. One solution is to get the correct shear bolt from kubota (only 1), then buy a bunch of grade 5 for the auger and grade 8 for the impeller. Use your 1 OEM shear bolt to mark where the grooves should go on your replacement bolts and then groove the replacement bolts. I put the bolt in the drill press at low speed, and with a very thin disk on the hand grinder, put the grooves as marked on the bolts. You can make a dozen shear bolts in less then half an hour. When these shear, the break is so clean, the bolt remnant left in the shaft almost drops out on its own, when the holes are lined up. To remove broken bolts from the auger and impeller shafts, it is helpful to have punch marks on the inner and outer shaft that are aligned when the shear bolt holes are aligned (this from another member, don't remember the name, but you know who you are) since you can usually not line them up by sight in a snowstorm, in the dark, freezing your fingers off. Hope this helps ease some of the misery of shear bolt replacement when the snow really gets going.
