I'm having a little trouble figuring out how my backhoe subframe should have been assembled. The backhoe manual has nothing on the subframe, and I do not have the subframe instructions. (I have a 758C on a TC35DA, but I think the same subframe is used for the 757C and all class III tractors.)
My subframe braces were a little loose, and allowed the backhoe to rock up and down some. I discovered that the diagonal brace on the right side was attached to the frame with a smaller bolt than the left. The hole in the brace and subframe is 3/4, and that's the size bolt that was on the left side. The right side is the side with the bracket shown in the attached photo (photo shows an unassembled subframe, not mine). My bracket was sandwiched between the brace and frame using a 1/2 inch bolt.
Anyway, it's this bracket I can't figure out. First of all, what is it for? Secondly, how is it meant to be attached? Mine has a 3/4 hole I can't see on the one in the picture, but also a mysterious corner cutout with a smaller hole. I thought maybe it was meant to be attached in the second frame hole with the corner cutout adjacent to the brace, but it doesn't seem to fit there. If it just gets sandwiched between the brace and frame like mine was, what position should it be in? If you have the subframe instructions, or a good picture of one you know was installed correctly, maybe you can help me out with some information. Thanks in advance!
