While on the internet, I was looking around for information why my Case 480C backhoe will not start when under 50F without starting fluid. Over that, it starts really hard without the starting fluid. I found a service manual. Great! I was going through the tune-up mentioned because I thought it couldn't hurt, right? Well, upon re-torquing my head fasteners, a nut broke! WHAT! I was replacing the stud that holds the valve cover down when I heard a snap and felt something ricochet off my cheek. I was dumbfounded with the stud in my hand as to what just happened. Re-torquing the head fasteners has now left me with no way to work now because I need to hunt down a special nut to replace the one that broke AND the one I'm going to replace because I don't want the other one to fracture as I'm using the machine if I do not replace it.
I cannot find anyone who carries this nut anywhere on the internet through a Google search. Honestly, I did find one retailer who had them listed for about $75 each! No freaking way! I'll put a grade 8 nut on it and fashion a female bolt to turn on a few threads of what's left of the stud in the head.
My question is....Where can I find 2 NEW nuts A51114 (nut - head studs, 1/2" NC and 3/8" NC)? If they are not available, what would be suggested?
Thank you!
