I can actually get some of those at Lowes, is that a type of shear pin I should perhaps be using? When this system works, it's great. But when it fails without a consistent pattern, then it is frustrating. Anyway, I will keep reading what gets posted. thanks.

MW Shaw is right as far as I know about that being the correct shear pin, it may look like a clevis pin but that is what they give you at the IH dealer and that's what mine had in it when I got it, with the little spiral split ring (see pic, which also costs about $.50 more than the pin?!?) to hold it in. I have not seen the ones with grooves? have seen ones that look like shoulder bolts but can't find one of those that is long enough. I have not bent or broken a shear pin (geeze! hope I don't jinx myself) and have't checked but I believe mine is set up with the key and set screw on the other end.
The issue I'm having is on the other end, but by that parts shot you have I can't tell what #'s 6 & 9 are?
I also wondered the same thing, if we used grade 5 or heaven forbid grade 8 bolts in there won't the belt slip when there is a problem?
Maybe some of these more experienced guys know the answer, I too would hate to sabotage the system but it does get very frustrating.
Any ideas are greatly appreciated.
Thanks, Vic
