Mechanical rgn sagging -- stretched locking plate?

About the only way I can think of to repair that correctly is to take it to fab shop and see if they can build it up and line bore it back to its original size.

 

A line boring shop will usually run a number of weld beads in the worn down area to build it up. Once that's done they'll mount a line boring machine on it to cut the bore back to round shape and in its original location. Its a fairly common procedure used on earthmoving equipment when bushing bores get pounded out.

This is assuming that it can be done on your trailer as the shop would have to assess it.

 

Have just built them up with 7018 then shaped them with a die grinder nothing to fancy, but if the piece is stretching i would look into getting new ones. The lowbed I was on was on dirt roads for 80% of its life so they were wearing not stretching.

 

You might check with Trail King. I know they can repair/replace pretty much
any part of their trailers. Don't know how expensive they are...…..

 

You still have an awful lot of metal there so I don't think I would worry too much about breaking the dogbone, but building them up as others have mentioned might be worth looking into.

 

The only problem with line boring is the holes in the dogbone were oblong from the factory.

 

Could do the line boring in 2 spots to make it oval.

 

We’ve never tried that with ours, I guess you could move the stanchions up some after you make the first bore and just cut the top of the hole. Never thought of that.
