How do I fix this - Rounded out holes

[MossRoad]

Hi Moss, I was saying to make the hole big enough for the bushing with a plasma cutter and then weld the bushing in place filling in where necessary. I would trust that more than welding the new tab on. My welds have never failed but I am always worrying about them.

Gotcha! If you have access to a plasma cutter that would work, I guess. But if you're going to go through the trouble of plasma cutting a hole, grinding, fitting a bushing, welding the bushing, etc..., why not just cut off the tabs and weld new ones on? Trying to stay away from the tank?

How would you plasma cut the lower tab? Or is the lower tab not damaged?

For bushings, was it you I was having discussions with about the bushings in the blades and using DOM tubing VS iron pipe? Anyhow, On Line Metals has small quantities of DOM tubing.

Just put a flat ended end mill the size of a bushing in a drill press and plunge it through. Drills walk, flat ended end mills don't walk if you go down gently and in small increments. A drill press will plunge them just fine.

He's gonna have trouble getting a drill press into that location on the tractor.

I thought he had it off the tractor. You would know better than me - you have one of those PTs.

Tack a 1/4" plate with proper sized hole over elongated hole/tractor piece.

Use a hole saw with an air drill-the 1/4" plate will act as a guide and prevent the drill from walking.

Remove 1/4" plate when done drilling.

Insert bushing

Thinking about this some more, what I would do is make a piece shaped like the worn out hole. Wouldn't be that hard with a cutting torch and bench grinder. Drill a hole in it for the bolt. Chamfer the edges and weld it in. You could trace the hole shape on a piece of cardboard with a pencil.

Moss, I would just use an actual steel bushing.

Carl, the parts list says those are 3/4" pins

Is the bushing going to accomplish anything other than just keeping the hole round? Since it wore out, would it be prudent to put thicker tabs and a longer bolt on there? Just wondering out loud. I'll be checking mine a little more thoroughly from now on.

I would just buy a couple of Williams washers and weld on the out side of the tabs. Williams Washer

The bushing should be a lot harder with a lot more wear resistance than the original steel. I wouldn't put a soft bushing in.

My neighbor who is a heavy machine repairman came over. You know how you over engineer things. He said he would whip up a couple of tabs at the shop for me. he said he would make the end that attaches to the tank a bit shorter. I would lay these over the other tabs and weld them down. I need to go buy a longer bolt..

Seems like a logical solution. Thoughts? I mean I would love to attempt to fill with some welding rod and all that sort of stuff but in the end, this seems to resolve the issue immediatly and in a way I might be able to handle more or less on my own.

Sounds like a K.I.S.S. solution at its finest.

Yep, on a simple piece to make like that bracket, making a new one is the easy way.

the copper pope works, but isnt the best for a "pin" hole without doing some final machine work afterwords. IE: use a SMALLER piece of copper than needed, then do a final bore to size. Because where the copper holds the weld back wont be a smooth area, and will wear the pin out quickly.

But works great for other holes that dont have a pin that rotates in them.

Boring the whole hole oversized is another good solution, allthough not in your case. Given the severity of the wear, keeping the center of the hole where it is and to go large enough to get back to "true, you would have little to no material left to support the bushing.

Copper Pope. There is a joke in there somewhere and I can't find it.

In all seriousness LD, thanks for confirming my copper idea has legs. Yeah, the bushing idea never worked in my estimation. The location of this whole setup is beyond my drilling equipment skill set.

 

[bigdeano]

The support for the bolt is going to be farther apart. I hope the bolt doesn't bend from the hyd cyl force.

 

[SpringHollow]

I would have no qualms using a PC to make the hole acceptable to weld a bushing in but sounds like you have a solution in place.

[jimmysisson]

Is the cylinder end greasable? Did the pin seize in the cyl end and THEN wallow out the tabs? You'll want to make sure that doesn't happen again if so. Maybe tack the pin in place to where you could grind the weld out if it failed again, or bent as another poster mentioned. That way you'd know when it got tight. Though I don't suppose you'll let that zerk go unnoticed again.
Good luck with it.

No Zerks on these particular eye connections. We have to spray them with Teflon lube.

Its a craft beer.

If no zerk there, this is a good time to remedy that.
