OK, I know this isn't the right way to approach this, but here goes....
I have no year of mfg, no serial number. What I was handed, as the house machinist, is a pin, location unsure. Somewhere in the rear frame/suspension zone. It is broken. I can tell you a few things about it, and maybe someone can steer me to at least the correct name.
It's a bit over 2-1/4" OD, undercut (relieved) in the center. Approximately 16" long. The ends (~4") have had additional heat treating, such as case hardening such as nitriding, carburizing, or flame or induction hardening. File hard. It's probably Metric, so these are just rough measurements on broken pieces. Each end face has two drilled and tapped holes, 180° apart. There are flanged caps that are bushed to receive the hardened and ground ends of this "dogbone". Each cap fits closely in a bore I suspect in a frame member, since there are also two jack-screw holes tapped in the flange. It would seem that with everything aligned, the two bolts on the end faces pull the caps into position where they are in turn bolted to the frame. or vise-versa. I suspect there may be shims involved to set end play but I can't be sure.
This seems like a part that would have common usage among machines with similar frames, but I can't be sure. All I got was the pieces, and new caps to fit to. I'll have to establish an accurate OAL, especially if my supposition about shims is wrong.
By that description, can anyone at least tell me what the proper name of this pin is? Given time I can come up with the machine data, but for the moment, it's lost. I've been told the OEM is about $850, but long lead time. I think that was a guess.
Meanwhile, the machine is obviously down, and while we need 4 wheeled loaders, only 2 are running....both with no heat, so have whining operators. After all, it's only in the teens.....well has been a couple of days. My thing there, other than sympathy for the ops, is fogged glass and loss of visibility. Someone or something is going to get run over. Heater cores seem to be clogged on the Doosans. Glad those aren't on my list.
Thanks for any help!
