Welded bushings

[Sberry]

I am working on a loader and the bucket arm bush is outright gone, been for a long time and the po had come up with a greasee scheme must have worked for a while. Assuming we simply weld up the hole or shim/weld up with heavywall pipe and side shim it to reduce dirt, pump some moly 3 in to it nd let it wear steel to steel how long could we expect to run it?

Better off having it line bored and new bushings pulled in, possibly bore welded then bored back to size if needed.

I was wondering how long a fix lasts? The bore is already ruined. I been looking for parts and so far it's a slow go. Ain gonna hurt one of the holes any more than it is. If we wore it out could always do it again.

It's Dresser 515. I was trying to find some parts listing. So far doesn't seem like I can find parts pages similar to JD.

I am going to get a pic of the cutting edge also. There was a little creative work done to it too. The bucket link needs buns and seals at one end and the top could make it with seals. Looks like a disk bearing seal.
I understand mild isn't hardened bush but I am sure I am not the first with this scheme. Be different if it was not eye worn and headed for 5000 hrs of service vs 500 utility.

If your looking for heavy usage I would do what JLarson said to do.

It never lasts for long. Whatever piece of pipe you stick in there moves around enough to break the welds and then it just becomes pieces to grind on the pin.

Some pics. would really help.

Ithete was a minor bend in the arms, less than 1/4 in one and I bend one back 1/2 or so and got them within 1/4 and don't think I gonna fuss with it anymore.

I would like to quote. Let me see about pics. I did some measuring and am surprised how localized part of the damage is. I understand hard use, I understand it not being strong enough. It was working with a piece of hot roll in it and a missing bushing. I just made 2 bushings from 2 inch sched 80, 1 side might even be close enough to put seals in it and even a chance I can do it to the other one. I found trailer wheel seals at auto parts 3$ a piece.
Would motion industries have bushings?

Ok the stuff.

I think the last one is the link. It needs replaced now.

Probably need to bore for oversize bushing or build up to fit original size and line bore. Depending on how much out of round a split tension bushing may be an option. Pipe by itself will too soft and not last. Probably not a good fit either.

Loaded trucks for years with a 980B with DOM tubing welded in aligned with a shaft old junk aint to fussy

And if it was line-bored that 1/4" of bend wouldn't matter one bit because the pins would be on a single axis.......

I was wondering what the real life might be. Not going to work in in a pit all day. Mostly simple utility, some snow and a little digging and bucket hauling. I might be able get it close. Looks like inam going to get the sleeves quite tight and weld the ends in. Its not a huge deal to.cut them out down the line if we really ran it much. If there was more in this area would invest in the equipment. Does a guy but sleeve and cut stock bushings? I really don't want to become a machine shop, if I was already tooled it would be another matter. I was thinking there would be ready made parts on hand. I see lots of Cat and JD, nothing for this. Even 1 bushing would make it easier, actually 2
