Did this same thing on the swing arm bearings on a big tractor mounted hoist where the shaft had worn straight through the bushings into the steel. Only thing I did different was rough up the outside of the bushings with a course file and clean out and rough up the worn out hole with a round file. Been working well now for over 2 years with 3-4 months of heavy use every year. I used Loctite epoxy but I'm pretty sure any decent epoxy made for making repairs in metal should work fine. When it comes time to replace the bushings, a little heat will soften the epoxy up pretty quick.
Dealing with similar issue. Glad to hear there is a simple solution. Don’t need anything fancy for a high hour machine with light occasional use. Thanks for taking the time to share the info!
tbh I just use JB weld for these the same way (metal infused epoxy. resists cracking and impact.) to replace: weld a bead on the inside of the bushing then hit it with water. Feet of the weld bead pull up when cooled deforming and reducing diameter of bushing. if the epoxy is damaged hit it with a file and replace. great vid ty
Years ago I used epoxy to fix the crankshaft on my car. But I only had to fill in a groove where the pulley had worn a groove around the end of the crack shaft. I filled in the groove and sanded it flat all the way around and it kept the pulley where it belonged centered on the shaft.
I mig welded inside with soft wire and used a die grinder to fit pin and bushings in snug on 580 case. Epoxy may last a while. Belzona is strongest epoxy used in nuclear power plants. That may last longest. Good idea
knowing that Chevy glued pickup doors on...we know epoxy's have evolved to something beyong glue. Is it still holding up? For my project, I'm going to be braze back-filling mine after adding new larger bushing races. (when the races were too big... (custom created by a company called Misumi , there' online of course ) lot's of careful dremel work to fit them...but the orig. John Deere bushings mate up nicely w/ .006 hardened to hardened contact. ( john Deere 350c track loader )
@@57bagre well you just answered my Question. I have a Kubota KX 121-3 with the same problem. I’m glad I ran into your video. Maybe I missed something. Did you rough up the mating surfaces at all? And what did you clean the mating surfaces with to insure a good bond. Or am I over killing it.
Thanks Gordon, I've done the same repair to a 4 ton Kabota, it's holding up perfectly after many hours of work, £6 for a tube of epoxy....for the safety Sallys the worst that can happen is your back to square one and the sloppy joints come back. I fitted new pins a nd bushes to all the bucket links and it's now back good as new. This anchor fixing is not the same stuff as JB weld or basic glue it contains fine grit and I also had to use a hammer to tap in the new bush because even before it set the slop was gone. Thanks again Gordon.
@Jay Smith It was good for a long time, a few hundred hours or so of work, the boom to dipper pivot literally ripped out of the dipper arm about a year ago, after hours of rattling granite rocks in a griddle bucket, with the dipper removed all the pivot bosses got replaced, I think mine was damaged with pin coming half way out before I bought it, one bucket having a bent ear, I fitted a quick hitch and did this "bodge job" as soon as I bought it so I didn't need to remove that pin to change buckets. Hope it helps.
so far real good, no sign of the epoxy breaking up or coming out, but I don't use the machine daily, it probably only got a couple hundred hours since that repair. Thanks for asking.
Gordon Robertson DIY could I use this meathod on a control arm bushing in a car? The bolt is rusted so badly, we've tried everything to try and replace the arm
I guess epoxy might limp you by for a while, but that's going to have to be welded and bored. You could take that link off and take it to a machine shop and have it welded and bored. I would charge $2-400, depending how it is worn. I'm sure the epoxy won't hold, but let's assume it does. How would you replace those replaceable bushings the next time?
It was sloppy when I bought it 10 years ago, I used it that way for 9 years, I fixed that joint with epoxy 1 year ago and it's doing just fine for me and if I grease it often enough, it won't need replacing. as for you, you better have yours line bored or better yet, maybe you better buy a new machine.
I thought I was replying to the person who left a question on that video yesterday, now that I see who you are, I know you are just watching videos mine and everyone else's just to find something wrong or to prove you have a little bit of training on the subject and even less field experience. You shouldn't be so proud and negative, try a little more humility and look for something right instead of focusing on the negative, try going to church. Have a nice day.
Put the shoe on the other foot. I'm the one who has to fix this kind of thing when the next guy buys this machine and discovers what's been done. You do what you want with your machine. If you had replaced the bushings 10 years ago, it probably would have been fine. But if everyone did that, I would not need a line boring rig...
The epoxy will release with heat. I was skeptical of the repair, but as was said, for occasional use it may last long enough the owner. I have used this epoxy for the intended use, I thought it was a good idea for bulk epoxy use elsewhere by not using the mixer tube. A clever idea, thanks for posting this
People who think this a bad idea should know industry uses many sophisticated compounds to retain sleeves and bearings in bores, restore fits on shafts and more. Examples: www.loctite.com.au/3320_AUE_HTML.htm?nodeid=8802648195073 Lord and others make adhesives good enough to replace welding in many automobile bodies, and some adhesives pass NHTSA crash tests. ua-cam.com/video/rqZ1E4eV8RQ/v-deo.html
Dont think that will work, if you cant afford lineboring, you might try JB weld, its alot stronger than house grade stuff, Ive used it to fill worn seal surfaces before installing repair sleaves, have never had an issue after. The stuff that takes a long time to dry is much stronger than JB quick
Thanks for the concern, but that video is over a year old and the machine is doing fine, no loose joints, JB weld sells for like $5.00 for a thimble full when this concrete anchoring epoxy sells for $20.00 for about 3/4 a caulking tube full, I have used more of that tube on other jobs since and still have some left. That epoxy is very tough stuff. Thanks for watching.
It is amazing how little people understand about damage caused by force of pressure and rotational friction. Gordon you are part of that club. Epoxy is used primarily to affix object that are not required to move in order to perform a function . Furthermore epoxies are designed to resist longitudinal load not rotational loads . Epoxies are temperature sensitive , in far more failing rates than are any metal parts tempered for the job , additionally: epoxies degrade when they come into contact with solvents , lubricants and other assorted chemical, greasing that joint will speed up failure. Assumptions are not the way to approach anything. Ask how the family of the woman that was crushed to death in 2006 by a 2 ton concrete panel affixed by anchors and epoxy that landed on her car as she entered the Boston 16 billion BIG DITCH tunnel how they feel about epoxy . The woman assumed she was safe entering that tunnel that has had the entire ceiling removed since the accident because the anchors held by epoxy failed miserably to hold even a longitudinal load . If any manufacturer engineering department could get away with approving epoxy joints for any heavy machinery at all that will be exposed to tons of pressure per square inch .. they would have done it long before you took the shortcut. Chemical engineers know better than to even suggest it , this kind of nonsense should not even be entertained as a joke. Wasted time , yeah he might get enough use out of it for the completion of the video ...that is all.... in the real world of work it will not last long enough to carry its own weight after three rotations of the implement. Pictures are better than statements ... still working fine ? I doubt it ... 40 years as licensed hoisting engineer that has operated cranes. excavator , wheeled or track up to 500 hp more than qualify me to say that this epoxy fix it will not last a hard days work .
What a "pompous ass" response! OK, we get it, you are an ace engineer, ready to pounce on the "uneducated masses" for their ignorance! The guy DOES SAY he isn't sure it's going to work, but it's worth trying; what is the worst thing that can happen? Is a woman going to get crushed because the epoxy didn't hold? All the epoxy has to do in this case is to keep the bushing from rotating and to fill the void that was caused by wear. The shaft is rotating in the bushing, not the epoxy. Worst case scenario, the epoxy will get squeezed out since its compressive strength is lower than that of steel. In which case he is no worse than he was when he started. Give the guy a break for Christ's sake! Feel better flaunting you credentials?
I think this was an amazing idea! And apparently Mr. Line boring guy has no idea what he’s talking about on epoxy. He’s just worried about not having a job because of great ideas like this. If he was well aware, he would already know his job was in jeopardy due to the Nordlock pins and bushings!
It is amazing how little people understand about HOW A BUCKET BUSHING WORKS.. OR RISK EVALUATION.. The type of load is a compressive load... not longitudinal, not rotational, there is next to no frictional load in a bucket bushings outer diameter its a compressive load witch is why it got pushed out to that diameter in the first place.. the worst thing that can happen is the epoxy fails (crushes from compressive force) then crumbles out and its right back to how it was so no real risk here.. not like 25lb bucket will fall on a woman.. because there is still a pin that can carry about 60tons before it even bends that prevents that from happening.. you never operated anything in your life stfu.

This is a awesome idea and for those who think it’s not then go spend $3000
Thanks for watching and commenting.
If you don’t wanna spend $3000 have a welding shop make you up custom bushings👍
If this fix still working today sir?
You can do what I did and have a welding shop make you up a custom bushing
Did this on my son's mini it was worn into the bosses when he sold it years later the guy couldn't believe how tight it was
I can't see how this wouldn't work. JCB mini excavators use plastic bushings in the dipper end.
Been working just fine for over 4 years now. Thanks for commenting.

Just buy some bushings!
Now, remove that bushing as part of normal service... after epoxying it in place!
