Just rebuilt the kingpins on ours. Then the boys and I replaced the swing cylinder ear pins and bushings. Liquid nitrogen is cheap and shrinks the bushings perfectly. We just got the swing cylinder mount bushings and the lower boom tower pin and bushings. Going to replace them tonight or tomorrow. Our old 580d is loose. But we are slowly getting get tightened up. Looks like you are doing the same. Good luck. It's pretty easy. Just time consuming and costs a lot. Every time I get parts its $500 or more. It adds up fast. I'll deffently keep the bottle Jack method in mind. I'm sure we will be doing this soon. Thanks for the video. Helps me understand what we are up against.
Liquid nitrogen was another consideration I had, I just wasn’t sure where to source it and whether I needed to provide a vessel to store/transport it. I’m glad you found it worked great, I’ll likely employ that method on the next bushings. Time is precious!
@@fixaday you need to get a storage device, and the gas can be found at welding supply, contact them about what you need to carry it in. cant be air tight, will explode.
I made bushings and pins on my lathe for a old 1969 Massey Ferguson model 54 backhoe a month ago. It had spherical bushings that are essentially a big ball within a race (think similar to a heim joint without the threads) and they were totally obsolete, not even able to match em up to something close, so bushings and new pins it was and it works great. I had to weld the lower bushing in because the hole was fucked. I drilled and step cut a groove inside the bushings, for complete grease around the entire diameter of the pin. Like I said, it works great and considering the oe parts are obsolete, it is a proper permanent fix and should last what ever life is left on the machine, probably another 2-3 thousand hours. If there is a will, there is a proper way in the equipment world
That's awesome! Looking at the pins when they arrived, they seemed to be a basic alloy that anyone could make. The bushings may of been a hardened material though, I'm not sure. I know if I had the material laying around, I'd definitely give turning my own a try! Thanks for sharing.
take a saw saw and split the old bushing before pressing it out. Just one side does a lot ...2 sides even better A bit of dry ice goes a long way on installing the new bushing
Should use a socket or something when hammered out that bushing, hit the edge with the hammer a lot If you have a die grinder you can cut a groove into bushings too
Did you cool tge bushings before trying to install? Freezer is good but you can get dry ice at a lot og grocery stores. Dry ice acetone bath is minus 78 degrees
I worked on equipment for years and you cut a groove into the bushing and collapse it in on itself and heat the hole and freeze the bushing to reinstall it
Do you know how to get the swing cylinder bushings out? It looks like on my 580SL that they can't be pushed right though because only one end is open where they are installed. Thanks.
@@stevenpringle7813 Same way on the 580E. They are blind pockets, the bushings have to be weld-shrunken, machined out, or require some other unconventional method. I can’t remember what the manual says off the top of my head.
I notice that you don't lube your threaded rods. Also, did you consider freezing your new bushings prior to pressing in? Heating the surrounding frame for the frozen bush to press into?
I did lube them, yes. I started with MP grease and switched to anti-seize. Both the thread and the nut and screw flanges were lubed. As for the bushings, I had planned to sourced liquid nitrogen as a last-resort. If the bottle jack had not worked or if it was too much stress for the frame, I would of taken that route. As for heating the frame, on large plates like these, the heat will actually expand against the surrounding metal, causing the bore to shrink rather than expand.
Thank you for the vid and the response. I have had great luck expanding a captive hole's diameter by heating the surrounding boss materials, regardess of "thickness" making bushing/bearing installation much easier. Freezing the bushing/bearing is often even a greater assist.
Not sure which piece you’re talking about. There is a pear-shaped flange on the upper pin. If you’re referring to that, it’s used to fasten the pin to the swing tower to prevent rotation in the swing tower bore. It helps focus rotation to only the bushing.
@fixaday on the bottom verticle pivot point for thhe boom. I have one on my parsons koehring too and it looks like a pin holds it in place maybe? The pin is sheared off on mine.
@embededfabrication4482 Oh, right. Yes, they are very important to prevent pin movement. If you have a way to drill or weld a new one into place, it will give you a lot more life out of the machine.
I only need to change lower bushing, do you think it would be possible to push it in from bottom jacking up against weight of hoe. I was going to freeze it .
I believe using nitrogen would make it possible if done quickly, but I do not believe the weight of the backhoe would be near enough on its own. If I estimated by feel (comparing the 20t bottle jack I used in the video to a 20t shop press), it required between 6-10,000 lbs of force to press them in at 90 degrees Fahrenheit.
would you remember the part number for the bushings you installed on the swingarm . the one pin# was12353 that was the lower pin #.i cant seem to find the bushings that you had .i have a 1996 case 580E i have the pins but cant find the bushings. any help would be great Thanks . vince
I don’t have the experience that you do. But I really like watching your videos. I have similar job that need to be done on my equipment that I am looking to do myself. Would you please tell me where I can get find the tools you use and the name of the tools you are using so I can purchase them
There are several used in the video, but the specialty ones are as follows: -20 ton bottle jack: Harbor Freight, auto parts store, industrial supply, eBay, Amazon -Master wheel hub & bearing puller: Harbor Freight, eBay, Amazon, or rented from an auto parts store. (I only used the pucks from the kit, not totally necessary) -3/4'' 600 lb-ft torque wrench: auto parts store, eBay, Amazon, industrial supply -1000 lb-ft torque multiplier: eBay, Amazon, Industrial supply -10 ton porta-power: Harbor freight, eBay, Amazon, industrial supply Depending on where you, you may have more or less availability.
Not nearly as bad as my 530ck. Mine has about 7/8" movement up and down, and is ohmost worn through the bushing. Really not looking forward to welding it all back up, and having to run a linebore on it.
@@sammyk.p.6705 Ah, I misunderstood. Yes, there is some wear. If I had to guess by eye, I would say up to 0.015''. I sometimes see the upper pin wiggle in the swing tower bore. On the lower pin, the nut has kept it tight and shows no movement.
Two days, it could honestly be about a 4-5 hour job if everything goes smoothly. I tried different methods along the way but had I just used a bottle jack to start with it would of taken half the time and half the stress.
Excellent and useful video. I have to do this on a basket case backhoe I picked up at auction. You covered the basics well. Only critique I have is on installing the bushings. You could of saved yourself a ton of trouble by putting the bushings in the freezer for an hour or so. Then heat up the tounge a bit with a torch, go get the bushings, add some thread oil and they usually drop or tap in with a rubber mallet.. we use the same method in reverse on pinion bearings in differentials. We put the pinion in the freezer and put the bearing in the oven on 350.. when they are both at temp, bearing just drops on. Note you only get 30 seconds to 1 minute of work time before temps start to normalize and parts go back to size. But this video helps, answered the main question I had about moving the hoe around to get at them. Figure I'll just use a plasma cutter on gouge to remove bushings, out in under a minute.. 5 best shop tools.. oxy acetalyne, plasma cutter, vice, bench grinder, and a simple 115v mig.. thanks for the video

OK SO I HAVE REPLACED A TON OF THE BUSHINGS, YOU NEED TO BUY A HARBOR FREIGHT 20 TON PRESS, I HAVE USED IT TO REMOVE AND INSTALL ALL THE BUSHINGS WITH GREAT EASE AND NO RISK TO ITEMS LIKE THOSE REAR MOUNTS BY PUTTING A BOTTLE JACK ON THEM AND SPREADING THEM THE HF PRESS CAN ALSO BE HUNG SIDEWAYS AS LONG AS YOU HAVE THE JACK PART ON THE BOTTOM SO IT GETS THE OIL.

Good question, I’m not sure. Doubtful it’s a nest in the machine, it doesn’t get parked here. Around mid-summer the ants free roam a lot across the carport, idk why though. Maybe in search of moisture?
LOL OH HELL THAT LOOKS LIKE A NEW BACKHOE AT BEGINNING OF VIDEO, THE PLAY IN MINE IS LIKE 2 INCHES LOL. IM LOOKING AT THE COMPLETE KIT THAT HAS WELD ON NEW BOSSES, BUT HAVE TO FINE SOMEONE TO DO THE WORK IN WINCHESTER VA.
Yeah, My 580 is way bad. Previous owner didn't want to risk wearing out the grease gun I guess. The whole boom slams back and forth and front to back when your driving it. People were laughing at me. I had to remove the Construction King decals. Thinking about Construction Joker or something.
Absolutely, I take both of those very seriously. I started noticing some very quiet ringing in my ears (tinnitus) in 2015, and I use earplugs for everything now.

Could standard spherical plain bearings be used after adaptation? Would be easy to find replacements in the future.
Good I saw the video before I do mine it took a lot of guess work out of it for me. Thanks!

A bit of dry ice goes a long way on installing the new bushing
Great video with a lot of good info. Thanks
EXCELLENT! thanks for the work! PS. watch the backhoe frame's attach pins.... I would suspect that the tension rods are not torqued properly.
Before to instaling the new ring, put it in the freezer over night, then to put in vers easy.
Br from Switzerland

If you have a die grinder you can cut a groove into bushings too
Did you cool tge bushings before trying to install? Freezer is good but you can get dry ice at a lot og grocery stores. Dry ice acetone bath is minus 78 degrees
Didn’t cool them, I wouldn’t do this job again without doing that. Cut it too close for comfort for sure
Once those pins are greased that wobble will go away. 👍
Protect your cylinder rods when beating the hell out of stuff near them, or welding.
Do the bushings push out either direction? I’m making up fixtures to remove and install them.
I believe so, I found no indications of a specific orientation.
I have a massy Ferguson 50D .I need to rebuild the top and bottom tower pins are they about the same
Did you have to get the lower bearing plate made. I am having trouble finding one
I reused mine. It’s super hard steel, but I think any competent machine shop could make one relatively easily
@ did you gouge it off or just grinded the weld. I ordered d90863. It is 2mm thicker but I’m gonna use a flapper wheel and grind it down.
@tylerdecuir7500 the original welds were broke, so it was just sitting there
@ ah wish mine was that easy. It has more than just tacks.
What were you tapping on to get the swing cylinder pin out?
Can’t remember honestly, maybe a 1/2” extension.
@@fixaday Thanks. The funny thing is I didn't know you could see the top of the pins. I never stuck my head over far enough to see them lol.

You can use a hammer wrench instead of the multiplier.
Pro tip, put the bushing in a deep freezer for a day. You will thank me for that tip.
Definitely. I've done this on ball joints and wheel hubs on cars. Makes a huge difference.
What size socket was the lower swing pin nut. I thought 2 inch would have been big enough but no. Thanks Chris.
Mine was 2-1/4”
@@fixaday Thanks. That's what it looked like when I put a tape on it.
No problem. I hope to see a video of yours soon 🙂

It prevents axial and circumferential motion

Aftermarket parts sourced through eBay. I used the OEM part numbers to base my search.

Nope, none at all. There was still a large amount of bushing material left.
I was talking about the part that doesn’t have bushings. The part that has do not weld stamped on it.
@@sammyk.p.6705 Ah, I misunderstood. Yes, there is some wear. If I had to guess by eye, I would say up to 0.015''. I sometimes see the upper pin wiggle in the swing tower bore. On the lower pin, the nut has kept it tight and shows no movement.
