Cutting and Welding new backhoe pin

[2manyrocks]

I looked at the material uses and description of stressproof in the link you posted. I've never broken a pin before, don't know a thing about this, and am simply trying to understand what material I should use and how to repair this because it might as well be greek to me.

Get the 4140 pin...it will be fine. It is a tough material and not super hard.

There is no wrong answer. And without knowing the alloy or hardness of current pin.....all you can do is make an educated guess as to what is best.

Both 4140 and 1144 are common pin materials.

4140 is a little harder and tougher.....but also not as easy to machine and weld.

There are pros and cons to everything when deciding on alloys. There is no perfect material

Thanks very much. I really appreciate all of the suggestions and tips from everyone.

If I can find something that the supplier will cut to about 6 1/2", that may be a deciding factor. I am not good at making square cuts and don't want to spend a lot of time fiddling with my 4x6 bandsaw.

I would cut it with abrasive chop saw and weld it..... Bar only retains pin , it not like its a stressed weld....

You want the pin to wear faster than the bore it fits. I would just us cold rolled steel. It is polished and true round. Replacing the bushings it fits through is a lot harder welding project than the pin.

Could I cut off this hitch pin and weld it to the Terramite mounting arm? Is the material in this kind of pin okay for me to use? I can get it at my local store and it seems to be about the right length and diameter.

It says grade 2 and SAE 1010-1020 /IS4454

That would be a low-carbon steel similar to cold-rolled 1018 steel. Go for it.

Tolerances may not be as tight as you would like, but should work

I could get the pin and see if it's too loose.
