fixing elongated holes in farm equipment??

[pharmvet]

Im in the process of refurbishing a JD offset 8' disc. I have taken it apart and plan to have it sandblasted and painted. Im also planning to go back with all new bolts. There are 2 holes where the tongue attaches to the frame, as well as 2 holes in the clevis where the tongue attaches to the drawbar that have been elongated and wallowed out with use. What is the best way to fix this. I was thinking of welding in a bushing of some sort. What can be done. pics would be nice. thanks

I fixed something like this not long ago. I buy the category 2 or 3 adapter bushings that are used to adapt three point hitch sizes to other sizes. I cut, grind or machine the hole to fit so the bushing sits in the hole correctly and then I weld it in. The bushings have always worked for me, particularly for pin through type situations.

Like Mark said or weld them shut and redrill them. I've heard of using a carbon rod of the appropriate size and filling in around it with weld but I've never done that.

We got into the habit of using the proper dia. pin and would leave it with the implement.It,s wrong size pin that starts the oblong wear.Weld up the egg and redrill to the size of your pin:thumbsupave

To weld it closed and re-drill is good if you can keep your center. If not, Then the Carbon trick is king. I have repaired countless Snowmobile Suspensions made of Aluminum that were elongated because of loose or broken bolts and Plow Brackets of Steel on plow trucks.There is usually an indicator of where the hole is supposed to be. Stick the carbon in there and weld her up. It will not be easy if it is a dead end hole. If it is, Weld it shut and redrill..Using a carbon rod is still as easy as it gets. Or, Drill it to the next size and put in a bigger pin or bolt.

find some copper pipe the size of the pin and use it as a guide to weld around.. seen carbon rods for that too.

that or weld up then drill out true.

I've used similar methods. I've used metal pipe and welded it in. Others have mentioned the sleeves to weld in as well. I would try not to use the carbon method unless you don't plan on drilling it out to size. If too much carbon gets into the weld it can become rather hard to drill out, at least for HSS drills.

Most farm repairs like that to get it back on line I put a washer under part one on the under side of the frame after I get it aligned correctly and tighten down then weld washer's fast.

Tom, you reminded me of a way I fixed a hitch on a wagon tongue one time. Used the pipe method for the hole and sized out some washers to fit over it and welded it all together. Worked quite well. Pin was good and snug, just a little tap with the hammer and it went right in. :thumbsup:

I used a piece of thick wall conduit one time to repalce the outter shield on my 8n steering box once.. old one got bent sticking out of the stering box cover.

neat stuff you can do with pipe...

I have tube in various thicknesses kept on hand for this exact purpose (and also making stuff).

Select tube with proper ID and OD.
(It's good to have various thicknesses on hand for this, so you can have different OD with the same ID)

Drill out the holes if required.

Cut tube to fit.

TIG weld tube.

No more wobbled holes.

To play it really safe, I have some 3/16" and even 1/4" weld-on huge washers. This only works where there is extra space, but with tube + thick washers welded on... fixes most wobbled holes good. (And keeping the bolts tight) :thumbsup:

If there is room enough to weld in oversized tubing to accept a thin wall steel bushing - that will make the next repair simple as replacing a bushing.

Here's what I do.....Weld it, bore it, done......

Whoa! Is that a bore welder for the home shop? We've got a bigger version or two here at work but a home version? Where have I been? COOL!:thumbsup:

We have a couple of those at work too. Ours are BoreTek (sp?) brand. Been using them for about 25 years now. Pretty slick. We've welded bores from probably 1ｽ" through about 36". I don't remember what the cost of them is but don't think one would have one at home!
