Two things here that might help make this go a little better/faster. First you said if the pins they dont take grease you would "drill them out". Dont do that. They make a tool for $30 to $50....to clean out zerk holes w oil and a hammer...works great! Cleaned several just today that would not take grease with it! Next, this tip is awesome! Don't cut those bushing w a torch! Try this: Heat up the bushing w regular map gas torch ....just a little....next go find a large wax candle...or to dollar store and find the cheapest large candle you can find. With the bushing hot enough to melt the wax, touch the candle to the interface on both sides....you want the wax to flow like solider real good all around. Once waxed well, let cool. The wax does something on a sub atomic level and it breaks the rust barrier between the metals. After cool, hit it w the socket. This trick also works w rusted bolts! When a friend told me, i laughed. Then when i had an old well pump with a severely rusted large nut that would just to come apart w anything else, i siad what the heck and tried it. Took me to tries...and the 2nd time i made sure to get a good waxing. Such a large nut i dont think i waxed well w small candles. I let cool, mounted up the huge slip locks and pipe wrench, and w a few lbs force the thing practicality fell apart!!! I just laughed! Could not believe it. Since i have used this trick many times...works every time! Try it! God Bless!
Sounds like a good idea. Removing some pins on an old komatsu dozer soon. I'll give it a shot, not like it will harm anything if it don't work. Cheap too. Thx for sharing.
You were lucky that everything came out so easy!!! The pins and bushings on the Bobcat Mini Excavator that I worked on was a battle to get out!!! Thanks for the informative video though, gave good advice!!!
Many thanks Gordon it helps me so to know that it's possible to do it. I am in France and it's so funny to think that an American man helps me ! God bless you ! François
Plenty of armchair "professionals" in the comments talking a bunch of trash but I came here to say Mister, you remind me of the folks I learned from. Thanks for the good video and nice job on the fix. Great job editing too👍
great job. Only funny part was... to protect some steal tool carts with cardboard and a plastic chair from sparks:-)... but... everything turned out pretty fine
Thanks for your comment. Sorry if I gave a bad safety example, after 40 years of repair shop work, I'm used to doing things my way and often forget inexperienced people don't always know the limits of safety, or taking chances, I do take safety very serious and even when it doesn't look like it, I do know the limits and always have at least 1 or 2 escape routes. There are several fire extinguishers right by where I was working, a bucket of water by the grinders, and the cardboard was a good distance from the sparks. I knew it would not light up, but not everyone else would know how to do it like that safely. Thanks for watching.
There sure are a lot of nasty commenters on youtube! I think your doing a good job. Maybe you're not doing it the "textbook" way but so what! You are doing it how you know will get it done. I couldn't do any better and I enjoy seeing the different thing that you do.
Enjoy watching you do your thing. I have the exact machine you do, and had to the same as you. Slight differences in approach: I mig'ed beads on bushings (on bottom and top)...that caused them to loosen up and pop out. So, there was no scarring of bore. And lastly, I put bushings in freezer....they popped in without much fuss. Although one does save a lot of money, all those parts add up...lol I still need to tackle the knuckle at house...that'll be fun. If you ever get to that, please post a vid of that one...how to support the whole boom and arm without a ceiling winch. Hmmm. Plus, I heard those bushings are an absolute nightmare to remove. Best.
You're right about welding a bead or two on the bushing to shrink it, if I did it that way, I would probably use a stick with a 3/32 rod so I can reach in there better, If you look at my video on leaf spring pins an bushings you'll see the bushings were carbon steel and burned out quick and easy, as for freezing the new bushings, I never tried it but I don't believe it would make any difference because your freezer will only bring the temp down to 20 deg. (40 to 60 deg. less than where you are working and you only have seconds to get them in before they warm up, on the other hand, the same theory is valid if you slowly heat up the bore to 2 or 3 hundred deg. before putting in the bushings it would not cool down too quick, but at the cost of heating, I will just use the threaded rod and washers, but if I weld a bead on the old bushing to get it out, that is cheaper than all that gas I used to burn it out, but then the bore would not be as hot to be expanded enough to help the new bushing go in. Thanks for watching and for your comment.
Yeah, I used a MIG to make the beads...worked like a charm. The bushings were in there good. Great thing about the beads, is they made the bore smaller, and I used the old pin to bash them out. I really think the freezer trick made a difference...ymmv. Been a while since I did mine, but I think they were very tight when I tired to hand install them, but the freezer allowed me to 'lightly' tap them in. I do like the threaded rod trick...must keep that one in mind for future fun and games...best
Melli inBC - I’ve taken your freezer idea and raised it one. When rebuilding aircraft engines, to replace valve guides we would put the cylinder in an oven at 400 degrees for 30 minutes and the valve guides in the freezer. When everything was ready we’d tap the guides into the cylinder. Once the temps were normalized they’d never come out without a reamer. For inserting a new bushing into this Bobcat bore, I would think you could heat up the bore some with a torch and the slight expansion would assist in inserting the new bushing. Just a thought.
@@shubb1553 I have used this method on many different jobs with a tight interference fit where tolerance stacking made thing very very tight. It works exceptionally well.
Holy. Talk about dry bushings when you took it apart. Was it ever greased. I grease my excavator every day before using it and there is very little play if any in the bushings. Grease is your best friend if you own any equipment.
I wonder why the bores were worn out if the bushing were still present in the bores. I mean I could understand if the bushings were gone. I wonder if the bushings rusted tight to the pins and ended up spinning in the bores at some point? Do you have theorys about why the bores got sloppy? Nice video, really enjoying your channel. Thanks for posting.
If you're talking about the bushings that I used epoxy on, I believe they were worn completely through the bushing and into the bore then someone tried to fix it by just changing the bushings and they went in loose and broke, that's how it was when I bought it. Thanks for the compliment.
I haven't touched that repair since, I just try to keep it greased. If I buy another old wore out machine like that again I will certainly fix it the same way.
I'm sure I did, the machine had loose joints when I bought it, I used it that way and did regular maintenance on it until I replaced the bushings and pins. Thanks for subscribing.
From Finland? do you guys get summer way up there? I complain about the winters here in central USA. Thanks for the comment and I hope the project goes well for you.
Now is winter, too cold to make that kind of repair outside. Have to wait about 4 months :-) I hope so that it goes well, I have to dismantle whole boom because pretty much every pin and bush is prerry loose and need to change...
A shed full of tools and you didn't wire brush the bores or linish the pin of rust before sliding the new seal over that abrasive surface or pushing in the high tolerance bearings. That epoxy anchor cement is super strong in compression and shear but will crumble under flex.
Great video. Do you use the excavator much and is the epoxy still holding? I have the same issue with my PC50 but only use it for my personal stuff so can't afford to pay lots to fix it so Thank You for showing us a cheaper way.
Gordon Robertson . Thanks for the reply. I am now planning on fixing my PC50 using this method when summer gets here. Definitely appreciate your videos.
Hey, it won't matter one bit how clean your bushings and zerk fittings are if you don't ever grease them. My God, man, did you ever grease those joints???
Have cut many a bushing with a torch but have found that making a bushing driver just turned to the bushing ID and an air hammer work so much faster on the install and the removal if the ends not mushroomed as bad as yours. Great content 👍
+Nathan Schroeder I don't know when it became needed, the machine needed it before I bought it with over 2000 hours. I've been doing mechanic work over 35 yrs. and driving big trucks and operating equipment at least half that time and after I fix everything I find wrong with everything I've owned I got excellent service and longevity with all of them, so I believe it's a matter of maintenance and how much abuse it gets. with proper maintenance and minimal abuse I don't think it will ever need bushings and pins. Thanks for your ?
I don't know how your epoxy trick worked or if you even still have this excavator but if you do you can get that part while I'm bored they will look the whole inside of that hole in a bore it back out and put a new bushing in Bingo like brand new
I think I would of tried shim stock on the outside of the loose bushings, that's if I didn't have a lathe or friends with a lathe, the epoxy should last for a little while.
Getting close to 3 years now. It's a good fix for me, I don't use the machine very often, that's why I buy old equipment and do this kind of repair. Not recommended for new or heavily used equipment. Thanks for watching.
That’s how my late husband died. A board. Please chain it up to something, or just please do something more than just the board(s). I found him, 6 years ago. It was probably the 9,987th time he’d done that, and the last.

never had to check it again. I've had to take cylinders off and reseal them several times since I did this video and nothing caught my eye other than the leak. I just try to keep it greased and use the machine when I need it which isn't very often. Maybe I should do an update video for the skeptics out there. Thanks for watching and commenting.
Iam luck enuff to have a spray welder would have just built it up with some copper or mild steel till a few thousands at a time were the hole is egg shaped out .
you need to use some bearing grease and get a good penetrating oil it would make your work much easier and you beat everything all to hell, I know I have done this type of work for years.
Blow the cobwebs off ur wallet and get it line bored so if you're watching this video to learn how to .ok this video shows how not to. Spend the money now or pay for it later.

I'm happy to hear the video helped. Thanks for watching.
Typical!
Another trick to getting bushing out is weld a bead inside the bushing let it cool and it will shrink up and fall out
Plenty of armchair "professionals" in the comments talking a bunch of trash but I came here to say Mister, you remind me of the folks I learned from. Thanks for the good video and nice job on the fix. Great job editing too👍
Thanks for commenting.
You can also stick your bushings in the freezer to 'shrink' them prior to inserting them.
Thanks for watching.
Dry ice
Outside in the snow or ice.
A couple small tack welds would have shrunk the bushing and it would have popped out too 👍
Thanks for watching.
never had that work for me on the big bushing i work on
Like Devin Smith a tack with welder would shrink it lot of people think it would get tighter but it wont.

Put your bushings in the freezer for a couple hours before trying to install them. Will set right in the bore

How about over size bushings ?
how long did the epoxy last ?
So it's been 5 years was now. How did the epoxy hold up in those bushings?
I haven't touched that repair since, I just try to keep it greased. If I buy another old wore out machine like that again I will certainly fix it the same way.
Well shot vid really liked it 👍🏻
Thank you sir.
Awesome idea
I love your john Wayne voice
Gorden how well did the epoxy hold up on the worn out holes?
Holding up just fine, I'm sure it will last as long as I keep it greased
So I liked how you used the bolt method to get the bushing in, you could prob do that with pressing a new bushing in and popping the old one out ya?
That should come out easily , those bushing.
did you try to send grease in the fitting?
I'm sure I did, the machine had loose joints when I bought it, I used it that way and did regular maintenance on it until I replaced the bushings and pins. Thanks for subscribing.

I see the bushings are worn out. What about the pins?
Joel Watkins the pins are supposed to be slightly harder than the bushings so you don’t have to replace them every time you do bushings.
Hey, it won't matter one bit how clean your bushings and zerk fittings are if you don't ever grease them. My God, man, did you ever grease those joints???
It's a lot cheaper to buy a machine in this condition and do the repairs myself than to buy a new or next to new machine for 3 times more money.
