Given the owners of the equipment probably never greased or checked the machine your repair is perfect. Doing an "as new" line bore and press fit would be a waste of time if it's going to be abused in the long run. If your viewers want to see some real crazy repairs, try Pakistani Trucks on RU-vid. All of your critics will be silenced. Thanks for sharing.
Waist of time? My friend my opinion is to make it better then new or at least try it! If you have a attitude like that nobody wants to do business with you!
I understand I didn't like the fit either, but I'm pretty sure from the factory these bushings had no press fit. The other side had little wear on it and it slid right out. Not a great design but it works.
@@EEJester1586 don't sweat it, you or someone else will be fixing it again in a couple years.... maybe sooner. those bushings are absolutely press fit!! without that press fit, that hard bushing is gonna wear that steel and wear it away causing movement and eventually break the bushings again. that's a line bore job all the way, or make a new ear with the bushings already press fit or at least machined.
I know you are all total pros at this you folks that would walk away have at it. Just don't expect them to go to you when they want to fix it right. That fix although not a proper 100%fix will get it moving dirt and keep a job on time and that can be worth more than fixing it " proper". Keep digging people.
Those grease zerks aren’t required, just write your number on there, you’ll be back 😂. Great work as always, just what I needed before night shift. Keep safe out there, that big stuff bites harder as well.
I have done lots of repairs just like that. It's not the way I would like to do it but the machine was up and running and making money. The repair was more than likely just as good as the rest of the machine. Good job
I also do heavy equipment welding. With over 50 years experience.. This is just a patch job. There's nothing wrong with keeping your customer happy ! But give them the Choice of a professional job and a patch job ! And I also do line boring and facing.. I'll patch something up at 1st to keep them going to keep my customer from having down time.. Not having downtime is very important to your customer.. Working a scheduled shut down for repairs is good business ! Keeping America working with portable welding ! Nights, Weekends, Holidays, Anything to keep my customers from having down time And have them running their next scheduled workday on time ! No one wants to stick around while I'm welding the cracks on their full fuel tanks ! 🔥🤣🔥🇺🇸😎🇺🇸 American Pride ! ----‐----------------------- Good job with your welding young man ! Stay safe and always protect your eyes and fingers ! *"AMEN"* !!!
Aloha, thanks for the video. Cool action shots. We just did a similar repair on a D7. Lots of build up and grinding. Our piece was worn a lot worse, so we bent 3/32" rods to build up the center of the hole first and kept the heat down. Afterwards they went strait in with some 1/8" rod. Then they ground a stone the same size as the new 4140 pin and did a poor man's line bore with the stone. It all worked out, but it took about three days! Keep spinning plates. Pick from a place of abundance. Keep them in your frame. You're a high value male with these skills.
then you will need to throw out the hydraulic cylinder that is located below the work site . it was necessary to protect the hydraulic cylinder from welding .
Ethan, your a dead set legend mate. And G'day from Australia. I've got to do a very similar repair myself soon on a Hitachi ZX55U-2. Main Banana boom pin hole looks virtually identical to this dozer before your amazing work. You should be proud mate, that job was bloody brilliant and anyone who says otherwise is a waste of space keyvoard warrior. What people don't seem to realise is that when your out in the middle of bum fuck nowhere and the client doesn't have time to do a full cleanup and linebore because that takes to long and time is money... We reckon you did outstanding work, keep it up. Cheers, Kai, Kristy & Alegra
Nice, I tend to slit the weld on a pin like that with a 9" slitting disc that way the faces are clean. Field repairs are tough so cap tipped to you. My friend gave me a home made extension for a grinder it is like a stub axle so you can get inside a bore with a small wheel.
That has got to be a $5,000 to $10,000 repair. Hope that didn't insult you; I have no idea how to put a price on your work. But considering the cost of machine down-time, and the value of a proper repair extending machine life .... you are a real problem-solver!!
Hahaha you didn’t insult me. I wish I made that kind of money nah that’s really a easyish job compared to some I’ve faced. That kind of job is what I would call a camp job my favorite. Where are you can sit in one place weld one time move all your leads one time and finish the same day. Wish all my jobs were that easy.
All y’all talking about line boring is funny to me. This is a Crabtree bucket and if you ever met Jimmy Crabtree you’d understand. He probably had a more precision fit after eyeballing it and welding it up than it had when it left Yazoo City brand new 😂😂😂.
I'm restoring a ford cl40 skid steer . I looked at one video about rebuilding a cylinder for tips on how to get the jamb nut off . You tube........ 50 videos about various machines I didn't even know existed . Witch I also watched instead of building a cylinder. Gotta love youtube
Thank you. Yes sir I can weld with the other types of welding as well. MIG, TIG, and Flux core. I don't use them very offend because most of my work is big heavy and dirty. Stick is king with the work I do I don't have to worry about the weld having problems because of wind or paint or rust or some other stupid reason.
The thing about this joint is it never takes grease very long even new. Its the way it is made. Dirt gets imbedded in the bushing and it will stop taking grease its a high wear part just the way it is.
@@EEJester1586 you work on them, so you would know. If this is the issue, would it not make sense to modify things so that it will take grease and Last, Excavator pins and other pivots in heavy machinery that are continually loaded and operating in worse conditions than this still generally give reasonable service life
@@davidp8157 I don’t think any machine catches it worse than a dirt pan. When you run over a dirt clod the size of a minivan with 150,000 pounds behind you at 6 mile a hour for 10 hours a day it’s a tough life. Like cotton pickers, and Combines I don’t understand how they work as good as they do. You can modify things however you see fit but it works the way it is.
@@EEJester1586 first all great job!! Just a noob question do you think with the welding will it hold up just like it did up until now with the work they do on it? In other words will the fix that you did hold up in the long term just it did when they first time used it up till now or will you have to comeback to fix it again after a short run?
I know I'm way late on this video but have I've had good luck using a brass bushing the same size as what's required and using it to weld against to minimize grinding
People who do line boring are cringing, but I get it, your out in the field and needs to get repaired, who can wait until a machine shop can do it if they will do it. Good repair job, getting it done.
I think you repair it based on how it will be used. If it's used 40 hrs a week for years or 20 hrs in one year. A friend told me shitty equipment gets fixed shitty. Great job making it work.
No sadly I don't. All the line boring equipment you have seen me use is a friend of mine's. I want my own line boring stuff but I can't swing that much money right now.
@@zhenherald don't waste your money on them Chinese line boreing equipment. You can get a better bore with a drill peace of 1.5 cold rolled steel and a few pillow blocks and some lathe tooling if you gotta go cheep go home made
Don't want to grease it, they sure as hell wouldn't pay for a line bore. It's amazing the equipment I see at Richie Bros that looks identical. Paint and everything looks great, but a guy starts looking at friction points. No grease, and plenty of repairs.
That’s a 18R cone grinding rock you can buy them at some welding stores. Most of the time you have to get them off the Internet Norton makes a good one.
This is the 1st video of yours that I have watched, I will watch more. Good field repair, you do what it takes to get the customer back on the job. Thank you Sir. Oh btw I just subscribed. I’m looking forward to more of your videos.
Make sure the hole is really clean sometimes shiny metal isn’t clean. Can be dirt or oil underneath it sometimes caused them to stick. Use a smaller rod at first like a 3/32” once you lay down a good pad you can jump to the next size rod. Sometimes magnetism can cause arc blow. You can wrap your ground lead around the weldment a few times and make it stop. If it gets worse then warp it the opposite way (clockwise to counter clockwise) hope that helps.
@@EEJester1586 thank you for advice.It is magnetic field problem i think becouse rod was digging into metal.I tried everything only helped attaching multiple grounds with car battery jump cables.Thats with first hole with second there was no way of fixing it i gave up and made bushing on lathe
