Why Matt only has 56k subscribers is beyond me...excellent content...superb editing (and that is ridiculously time consuming)... He is at LEAST quadrupling the value of his equipment with his sweat equity...and he doesn't need receipts...he has videos...
Cylinder repair is one of the toughest jobs there is. There's a U-tuber channel, CCEA, Cutting Edge Engineering Austrailia. Great channel to watch to learn about cylinder repairs among other things too. Matt, just be very careful moving the cylinders and wear a back brace for added support, You don't want to end up like me with a bad back.
Kurtis's idea of cylinder rebuild is salvaging the ends of the cylinder and remaking everything else and doing upgrades to the greasing paths so everything is better than new.
Hey Matt, The safest and easiest way to get the stick cylinder off is to attach a chain to the bucket end and then attach a come a long to the base of the excavator and drag the bucket towards the machine until the load comes off the cylinder. No jacks or props to deal with and if you pull the bucket close enough the arm will almost support itself. You may need to throw something down to keep the thumb or bucket from digging in to the soil though. Good luck
I have the same job to do on my stick cylinder, but with far less equipment. I'm glad he was able to manhandle these things to the extent that he was because I will have to do so as well. There's an Australian video where he digs a hole, with the excavator to lower the stick, and then does the seal with the rod still pinned to the machine, but his machine could still dig. Mine might be able to as well if I'm willing to lose a gallon or so of hydraulic oil while doing so.
Matt, to get the stick cylinder off, I would build wooden cribbing up at the boom/dipper joint, then use a 30 ton jack to lift it up enough to take the pressure off the pins and remove them. While it is up, remove the bottom thumb pin and cylinder too. then lower the boom/dipper back down on the cribbing until it is time to re-assemble it all. Good Luck, I can't wait for the next installment.
Could an ACRO prop be used to lift the arm? Place it at the knuckle. Alternatively, could the tractor FEL be used to lift it up? Use a strap/chain to back of excavator to hold it up? Love watching your efforts. Keep the updates coming.
I was thinking an 8" log cut to a good length with some 2x4 bracing to hold it up. But cribbing would probably be more stable. Some sort of tripod could work as well and would be very stable as long as the legs are strong enough.
Mat, I worked rebuilding hydraulic cylinders as part of my job thru the years, I have to tell you young man, for the equipment / tools and experience you have, I think you are doing an exceptional job of getting them tore down, even with proper tools and equipment they can be stinkers getting them taken apart sometimes. Nice job sir, enjoyed the video.
@@JFirn86Q you wont get alot of pressure just blowing some air in, and this is why i said use a limiting strap. but sure if you plumb a high volume air line in, it could fire out pretty fast. but using a normal nozzle the flow wont be huge, but it will most likely pop the piston past the barrel. i would suggest that the reason cylinder repair shops dont do this is because they have tools to extract the rod. if you dont, improvise.
You are right. On a table to catch the rod it works very well . Although when you do it seems pretty damn dangerous, they dont come all the way out from closed. Its fast moving and speeds up exponentially for a moment Then slows the same way. IF IT GETS STUCK DON'T USE AIR TO START IT! That's an air gun! Matt was in a bit of a rush to move those. He could have inspected the rust and honed it with some 180 wet'n'dry paper or a wire brush in a drill. I'm not instructing anyone either. Use your own brain readers. These pages cannot think for you.
@@jackrichards1863180 grit would absolutely destroy those barrels. The barrels are extremely expensive on a boom cylinder. Last thing you wanna do is use 180grit on a cylinder barrel.
Cutting Edge Engineering out of Australia has some great videos detailing the rebuild process for hydraulic cylinders. He does a lot of Hitachis. Great video. Thanks for sharing!
Been watching your channel for ever (even before the CAT rebuild came into the picture). Admire your work and that you can do this all outside of a full-time office job (in the rain and in the dark!). I know nothing about any of this equipment and have very little mechanical knowledge but yours has to be one of the best CZcams channels. I love your thoroughness and how nothing seems to phase you. Keep up the great work. It surprises me that you don't have more subscribers.
Matt I still say that you are incredible for taking this project on, I've never seen anyone single person do what you are doing to this machine by himself without anybody else's help, again you are incredible, my love to the family and a big hug to Charlie.
Could a couple of screw jacks under the elbow elevate the boom enough to remove the thumb cylinder , and take the load to allow you to remove upper cylinder too . By the way , hats off for your attempt at world cheater bar record.
You are "super" man. Soooooooooo much work. I am sure that it is getting expensive. I hope that it will be worth all of your hard work. Well it looks like you have a lot of the main things off and being repaired. You have a lot of followers and they have faith in you. I just hope that you do not get hurt. Great job on the video. May the force be with you.
Back your dozer up to it and run a 2 part line with a snatch block under excavator and use winch to pull stick in and boom up. Might need to pick up bucket first and lay a log(s) so bucket teeth don't dig in (winch or timber lever) A couple feet should be enough to get both cylinders. Secure with heavy chain. You've done waay sketchier.
I've seen hydraulic shops modify engine hones by welding 4 feet of steel rod onto the hone so u can get it in the barrell of the cylinder. It works great
Thanks, Matt. Your patience is paying off, I like how you are taking your time and making sure you don't hurt yourself ... nobody said it would be easy, but it is doable, and you're getting there. Nicely done, from a fellow Washingtonian. 👍
You surprise me every video with the project depth of difficulty you're willing to tackle. I love watching your problem solving skills in action. It would be awesome to have you around come the apocalypse. :-) Thanks for your time and effort.
Matt, I had to fix a hydraulic line on my big backhoe. I cut three trees, maybe 15 foot long, set up a tripod (tied the trees together with holes thru the top with a chain). Placed the tripod over the joint, attached a chain hoist (like you have) and lifted and supported the (hinge), it worked well and I felt super safe working around it. Good luck!
Love your narratives!!! "Ugggh! "Ouch", "Awggg", "Umph!" "Yea, I got it!" "There we go..." (I wouldn't suggest anything different - it's real!) (Water in there....water in there....water in there..."
Use railway ties stacked up and then put a hydraulic jack on top to lift it up some to take the weight. Then use a couple of more blocks to support it and lower the arm on to the blocks and remove the jack. Same system they use for lifting houses....
I had a good laugh when you complained about the breaker bar pin shearing off with a 10-foot cheater bar on the end of it. Thanks for taking the time to make your videos!
This a delightful channel to binge on. An endearing blend of curious ingenuity and farcical stupidity, all while displaying a rare level of determination. Love it!
Hey Matt, just a suggestion in the future if you use that hydraulic rig on the front of you're tractor maybe instead of pinching the top of the cylinder between those plates to secure it you might be able to weld up a piece of pipe to insert into cylinders end fitting that would hold rod in place much as it would be if left on the excavator. Thereby using the hydraulic cylinder on the tractor to hold it in place, sort of like a stationary breaker bar to counter the air wrench. I think this would be more secure in all axis than using the webbing and come along or pinching it like a vise.
Matt, why not build a tripod to hold the boom off the ground then hire a local Towing company to come out with a light duty wrecker to do the heavy lifting? If we were closer I'd help you accomplish that feat. Once you finish the machine you can reassemble the hydraulic cylinders back on the machine.. hope this idea helps.😊
Everybody is correct Matt , anyone who wants to know the best and easiest way to strip down a cylinder just watch CEE Australia even the experts could learn a thing or two from this channel good luck mate
This is going to be so excellent when finished! I want to suggest you dig a hole for an in ground pool, so you can relax in it. Until your next project! 😂 🤩🥰
I find the rebuild so interesting! I almost bought an old 30ton excavator that would have needed some work as well.. ended up getting a brand new 6 ton excavator with thumb, blade and rubber tracks. Hopefully I can get enough work with it to pay for it but it can be transported easily and is ready to go (but the monthly payments are no fun). Still wouldn't mind having a 15-30 t someday.
Well done Matt, I’m always amazed at your ingenuity. For a one man band you certainly think outside the box in moving the heavy equipment around, well done, D minus.
Hey Matt,you asked for suggestions.. What about building or welding an A-frame brace to support the main boom?? 3'long at base by 3' wide at top made from pipe would be ample support...💯👍👍👍
Tall screw jacks may be used to support the boom , make sure to place some heavy shoring down or steel plate to support the weight and check for settling while the cylinder is removed . Long time viewer , enjoying the content .
I love your content. How meticulously you handle the problems. Also I can't imagine you benefitting from buying a newer machine with less hours as your standard of repair is pretty much get it like new, and a less older machine probably has the same problems only in a lesser state of wear. When you're done with this machine I'd love to see a calculation how much everything has cost, like you made with your previous projects. Your channel needs to grow. The level of repair you do is amongst the best on youtube, given that you're in a basement and not a professional workshop (like CEE etc who do this for customers, for a living. Their level of knowledge and possibilities in a big shop is of course on another level)
Cut you some wood cribbing square. Stack them under the main arm . Use a 20 ton bottle jack to lift the main boom . Then release the pins on the cylinder. Or skytrack to lift it . Then remove the cylinder
I, for one, would never guess those cylinders are quite so heavy. Exhausting work. You used some clever work arounds. One thing you learn from watching videos like this is that you can never have too big a wrench or tool when working of big, heavy machines. Those nuts are so tight for a good reason. Very nice job Matt.
It is nice to put an anchor point on the floor in a convenient spot in your garage. All you do is put a piece of plywood under the cylinder then with the one end anchored you pull on the other end with the tractor. Easy peasy!
For really torqued on nuts, you should look into getting a good quality second hand torque multiplier, they are a little pricey but will really help with what you're doing
hey matt, the struggle was real, and there was some real grunting happening here. that said, you continue to impress with your macgyver attack of the jobs presented to you.
Nice episode Matt. Really enjoyed watching you taking old excavation equipment and completely restoring them. Your attention to detail is outstanding. Almost like you're working on an aircraft. Can't wait for the next episode.
If you want to get the stick cyl. out, support the boom at the pivot. Weld some 3/4 x 2 strap steel to the sides , to lock the hinge. Something you can remove carefully later. I would also have a 3/4 pipe hardline from the compressor to a connection by the door. Good work so far, you are ambitious!
Great job.... Thank heavens for ratchet straps. The one area I thought Matt may struggle with more, was removal of the lower pins for the twin boom cylinders. However that system of retaining spring rings and their small locking pins offered no resistance, maybe they were kept lubricated by the hydraulic fluid leaking down the boom for several years :) Hope the shop can hone those cylinders for you.
Hey Matt, in your spare time😊, make a flat plate for your log splitter. A 1/2 inch plate against your wedge and 2, 1/2 in flats along the side and weld her up. drill a hole through the flats and the wedge and put a pin in and you will have a very useful shop press. I built one for my log splitter and have used it a lot. Great video series Matt, I enjoy watching.
Prop the knuckle up with a fence post. Your tractor should be able to take the weight off it. Lower it onto the fence post , the stick ram will be able to be undone as you did the other three. The boom rams are a large size for a bloke at home to manage. I reckon you achieved some better results than many other men might do? I wait tirelessly for your next video each time. Rusty cylinders often need a new one made up. I'm not sure you want to reassemble them yourself when repaired? They can be very difficult. Keep at it. We'll all keep supporting your channel!
Awesome content as always, And I know the struggle to get things done when your alone. Keep up the good work Matt, yet another very cool project which will result in a super nice excavator when your done. I would say as good a new if you do your thing.
Matt, your ability to solve problems with what's available is amazing. I've been with you since you got the old D4-7U dozer and enjoyed every episode. Thanks
Hey Matt, a quick note to help in future. If you have a nut that is seized, use two hammers, one 6 lb. and one 3lb. Use the 6 as a back up and hammer each face with the 3 lb, it stretches the metal just enough to allow removal. You can use hammer for bolts as well but not guaranteed to work as well as on nuts. Simply strike the top of the bolt head several times, the impacts jar the threads and cracks any corrosion so it breaks loose easier.
I hope your marking all the hydraulic hoses it’ll be easy to put them back in the cylinders after you rebuild them yes the seals a leaky. I’m glad you’re taking them down and rebuild them. You might want to find a hydraulic shop so that you can disassemble the cylinder from the piston. I think it’s torque to 650 psi on the nut to the cylinder. Good luck God bless you once again, please mark all hydraulic hoses with colored zip ties. It will be easier in the long run. I’ve done what you have doing on a PC 400 and it was no fun once again God bless be safe as always.
Advoid air on stuck clys. as when they move (break free) compressed air can shoot the rods out quite forcibly and cause injury or shop damage, your method with your limited resources while taxing is what I would do. No smart way to injure yourself. Start marking or grouping/segerating parts ASAP for easier re-assembly of clys Ray Stormont
Starke Leistung. Mit deinen Mitteln die du zu Verfügung hast. Alle Möglichkeiten ausgeschöpft. Wow. Not macht erfinderisch. Weiter so. Freu mich auf das nächste Video.
Jack the boom cylinder with a bottle jack and a 4x4, then place a 6x6 under it to support it to get the cylinder off. Be sure to use something to spread the foot print out over a large area so it doesn't sink. Curtis at Cutting Edge Engineering uses a vertical press to clamp cylinders and rams when he works on them. The press is bolted to the floor. Of course he has a HUGE press but it could still work for you. if you support the load they same way you are.
HD Mech here Matt, not that means anything but techniques I'd use in your situation. It's almost always easiest to remove hyd cylinders from the "motion" end first, ie: on the booms I would have used the gantry, tied to the rod end, pushed the pin in, and lowered it down to horizontal. It would be in a perfect position to lift out of the way once the base pin was pulled. Something to think about come reassembly time. The stick cyl I would build a crib out of 6x6 blocks (think jenga but only the outside pieces) and lift and support the boom enough to put some slack in the pins. It's going to be sitting for some time by your own admission, and it seems far to shallow of an angle to overcome with just a lever hoist. I would hope that a quick hone will solve your barrel issues but I would also be realistic about what kind of duty cycle this machine will see once back in operation. If your piston seals only last 6000 hrs instead of 10000, is it the end of the world? I would be definitely working on some kind of hyd flushing arrangement seeing all that water in the system, feed all the resivor return lines into a barrel(some of these will still have some pressure) and run every function at least once or twice stop to stop to purge as much water and an unknown concoction of oils out of the system. I would also suggest getting a hyd port plastic cap assortment as well, you probably will run out of one or two sizes quick but then just order those and your set.
Thanks for the advice, I actually got it cribbed it up last night. I'm replacing all the hoses and flushing out anything hydraulic, the entire system is full of crud.
Another satisfying long video, wishing that they were longer. Thank you, Your patience is paying off, I like how you are taking your time and making sure you don't hurt yourself.
It annoys me when tennis players grunt when they play a shot. Now you have started doing the same when undoing nuts on the cylinders. 😄 I do understand and have often done the same, Just couldn't resist. Don't stop grunting, keep making videos please.
When I did the backhoe dipper cylinder, I cut a 30" diameter pine tree down and lowered the main boom down all the way and measured up to the bottom of the dipper boom and cut the pine log to fit under the dipper to support it. Yours looks like it would be too great of a distance to work that way but I thought I'd mention it anyway.
Maybe you can weld a temporary brace on the boom to hold it in place while you remove the hydraulicrRam, Matt ! Because it would keep it from collapsing ! Only thing I can think of brother! The best way to keep something from collapsing is to make it rigid! Maybe an A-frame on pads under the boom to support it! I was thinking about it and a heavy piece of flat bar welded on each side of the boom temporary so the boom can not hinge enough to remove the cylinder pin, I can picture it in my mind but it’s hard to explain my friend! Seems like it’s something I’ve done before in the machine shop where I worked so they could line bore the pin holes! It kept the two parts together for boring!Good luck my friend and good video Matt!

Well, I think we have set a new high score for grunts and groans😁. I will definitely leave this kind of work up to you as I get a sore back just changing a tire. Hope the work continues to go well and stay safe..
Hope you don't have any neighbors near by. I also hear a lot grunting groaning and puffing going on there. Lol. I thought only us old guys did that. Cool video. Keep going 👍

Abom 79 is another CZcams guy in Florida that’s dose hydraulic cylinders . Did it for a living now he’s got his own shop .great channel content!
CEE is definitely a great place to learn but his setup is night and day compared to what Matt's got to work with. Nice work though Matt!
It really isn't at this level, we used to do em in 40mins, it's only got 4 parts and some seals

Apply air to the hydraulic side and push it out the way it's supposed to.
Consistently the fastest viewing content on CZcams. 40 minutes goes by like 10 and you just want more.
Love it so much keep it up as always 💘
I agree very interesting channel thanks Matt
I wouldn’t mind if some of his videos went a little over an hour. I watch Derek on VGG and get pretty excited when he puts out a 1-2 hour video.

Good idea Pete,I was thinking something similar but your idea is probably better!
Could an ACRO prop be used to lift the arm? Place it at the knuckle.
Alternatively, could the tractor FEL be used to lift it up? Use a strap/chain to back of excavator to hold it up?
Love watching your efforts. Keep the updates coming.
Likely wouldn't take anywhere near 30T, I'd be VERY surprised if 5T wasn't enough.
I was thinking an 8" log cut to a good length with some 2x4 bracing to hold it up. But cribbing would probably be more stable. Some sort of tripod could work as well and would be very stable as long as the legs are strong enough.
Just use some of that uncut firewood. Oh, I forgot. It's all cut up now.

Matt, you are one hard working dude. Thank you for sharing your experiences.
Remember you can put a limiting strap on the cylinder then blow air in to the hydraulic input to easily extract the piston.
Creating a massive cannon is usually not good practice. No real cylinder facilities do that.
@@JFirn86Q you wont get alot of pressure just blowing some air in, and this is why i said use a limiting strap. but sure if you plumb a high volume air line in, it could fire out pretty fast. but using a normal nozzle the flow wont be huge, but it will most likely pop the piston past the barrel. i would suggest that the reason cylinder repair shops dont do this is because they have tools to extract the rod. if you dont, improvise.
Far far safer using hydraulic pressure rather than the dangerous pneumatic method you suggest. Simple low pressure water pump would do.

Your channel needs to grow. The level of repair you do is amongst the best on youtube, given that you're in a basement and not a professional workshop (like CEE etc who do this for customers, for a living. Their level of knowledge and possibilities in a big shop is of course on another level)
love that breaker bar... and your adaptability
Cut you some wood cribbing square. Stack them under the main arm . Use a 20 ton bottle jack to lift the main boom . Then release the pins on the cylinder. Or skytrack to lift it . Then remove the cylinder
We used a 10 foot pipe and a bench mounted chain vice to remove piston nuts. (Cunningham mfg. Seattle Wa. 1994-96)
You my friend, are a MAD man!
I, for one, would never guess those cylinders are quite so heavy. Exhausting work. You used some clever work arounds. One thing you learn from watching videos like this is that you can never have too big a wrench or tool when working of big, heavy machines. Those nuts are so tight for a good reason. Very nice job Matt.
It is nice to put an anchor point on the floor in a convenient spot in your garage. All you do is put a piece of plywood under the cylinder then with the one end anchored you pull on the other end with the tractor. Easy peasy!
One of the most interesting channels I watch ! Lots of guys work , not many as hard as you do.
For really torqued on nuts, you should look into getting a good quality second hand torque multiplier, they are a little pricey but will really help with what you're doing
Yes, Great idea, I have seen these torque multiplier tools and are a great and handy to have .
Wish I'd liveded close to you, I'd defenetly swing by and give you a hand on these operations. Thanks for sharing your work.
hey matt, the struggle was real, and there was some real grunting happening here. that said, you continue to impress with your macgyver attack of the jobs presented to you.
Nice episode Matt.
Really enjoyed watching you taking old excavation equipment and completely restoring them.
Your attention to detail is outstanding.
Almost like you're working on an aircraft.
Can't wait for the next episode.
Install a bypass " T " before the reg. on your compressor to give you access to full air press. when you need it .
If you want to get the stick cyl. out, support the boom at the pivot. Weld some 3/4 x 2 strap steel to the sides , to lock the hinge. Something you can remove carefully later. I would also have a 3/4 pipe hardline from the compressor to a connection by the door. Good work so far, you are ambitious!
Great job.... Thank heavens for ratchet straps. The one area I thought Matt may struggle with more, was removal of the lower pins for the twin boom cylinders. However that system of retaining spring rings and their small locking pins offered no resistance, maybe they were kept lubricated by the hydraulic fluid leaking down the boom for several years :) Hope the shop can hone those cylinders for you.
Just keep on keeping on. I admire your tenacity, Matt.😝 I bet at times it gets to you but no matter what keep on keeping on!
Hey Matt, in your spare time😊, make a flat plate for your log splitter. A 1/2 inch plate against your wedge and 2, 1/2 in flats along the side and weld her up. drill a hole through the flats and the wedge and put a pin in and you will have a very useful shop press. I built one for my log splitter and have used it a lot. Great video series Matt, I enjoy watching.
Prop the knuckle up with a fence post. Your tractor should be able to take the weight off it. Lower it onto the fence post , the stick ram will be able to be undone as you did the other three. The boom rams are a large size for a bloke at home to manage. I reckon you achieved some better results than many other men might do? I wait tirelessly for your next video each time. Rusty cylinders often need a new one made up. I'm not sure you want to reassemble them yourself when repaired? They can be very difficult. Keep at it. We'll all keep supporting your channel!
I could not wait 😁
Good on yer Matt. Thank you for taking the time and effort to share your experiences with us.
Awesome content as always, And I know the struggle to get things done when your alone.
Keep up the good work Matt, yet another very cool project which will result in a super nice excavator when your done.
I would say as good a new if you do your thing.
Matt, your ability to solve problems with what's available is amazing. I've been with you since you got the old D4-7U dozer and enjoyed every episode. Thanks
The breaker bar antics at 22:00 is the best stuff. tenacious.
Boy, that Mongo impact wrench is the real deal! You're definitely getting your cardio on this project Matt!
Hey Matt, a quick note to help in future. If you have a nut that is seized, use two hammers, one 6 lb. and one 3lb. Use the 6 as a back up and hammer each face with the 3 lb, it stretches the metal just enough to allow removal. You can use hammer for bolts as well but not guaranteed to work as well as on nuts. Simply strike the top of the bolt head several times, the impacts jar the threads and cracks any corrosion so it breaks loose easier.
Cool, some hill billy action 😀👋🇬🇧
There is locktight on the threads, heat it with your torch then use your impact and they will come off.
I hope your marking all the hydraulic hoses it’ll be easy to put them back in the cylinders after you rebuild them yes the seals a leaky. I’m glad you’re taking them down and rebuild them. You might want to find a hydraulic shop so that you can disassemble the cylinder from the piston. I think it’s torque to 650 psi on the nut to the cylinder. Good luck God bless you once again, please mark all hydraulic hoses with colored zip ties. It will be easier in the long run. I’ve done what you have doing on a PC 400 and it was no fun once again God bless be safe as always.
Matt you keep telling us you don’t know what you are doing - nonsense you are an excellent allrounder 👏👏👏🏴🏴🏴
Stay safe and we'll see you next time.
I just love it when that cheap little red engine crane comes out, that little crane never gives up. You could use it to get off the boom cylinder 😀
maybe a electric winch for pulling power on the cylinders, but great mechicans mine
Advoid air on stuck clys. as when they move (break free) compressed air can shoot the rods out quite forcibly and cause injury or shop damage, your method with your limited resources while taxing is what I would do. No smart way to injure yourself. Start marking or grouping/segerating parts ASAP for easier re-assembly of clys Ray Stormont
Yep. Air makes a great spring that, when released, makes for unpredictable results.
Take care of yourself my friend. Looking forward to many years of your shared content. 👍👍
9:52 “I’d have to prop this up” it’s almost as if an overhead gantry crane could do that…….😊
Starke Leistung.
Mit deinen Mitteln die du zu Verfügung hast. Alle Möglichkeiten ausgeschöpft.
Wow.
Not macht erfinderisch.
Weiter so. Freu mich auf das nächste Video.
i loved the logspliter vice idear genius
Jack the boom cylinder with a bottle jack and a 4x4, then place a 6x6 under it to support it to get the cylinder off. Be sure to use something to spread the foot print out over a large area so it doesn't sink. Curtis at Cutting Edge Engineering uses a vertical press to clamp cylinders and rams when he works on them. The press is bolted to the floor. Of course he has a HUGE press but it could still work for you. if you support the load they same way you are.
HD Mech here Matt, not that means anything but techniques I'd use in your situation. It's almost always easiest to remove hyd cylinders from the "motion" end first, ie: on the booms I would have used the gantry, tied to the rod end, pushed the pin in, and lowered it down to horizontal. It would be in a perfect position to lift out of the way once the base pin was pulled. Something to think about come reassembly time. The stick cyl I would build a crib out of 6x6 blocks (think jenga but only the outside pieces) and lift and support the boom enough to put some slack in the pins. It's going to be sitting for some time by your own admission, and it seems far to shallow of an angle to overcome with just a lever hoist. I would hope that a quick hone will solve your barrel issues but I would also be realistic about what kind of duty cycle this machine will see once back in operation. If your piston seals only last 6000 hrs instead of 10000, is it the end of the world? I would be definitely working on some kind of hyd flushing arrangement seeing all that water in the system, feed all the resivor return lines into a barrel(some of these will still have some pressure) and run every function at least once or twice stop to stop to purge as much water and an unknown concoction of oils out of the system. I would also suggest getting a hyd port plastic cap assortment as well, you probably will run out of one or two sizes quick but then just order those and your set.
Thanks for the advice, I actually got it cribbed it up last night. I'm replacing all the hoses and flushing out anything hydraulic, the entire system is full of crud.
Another satisfying long video, wishing that they were longer. Thank you, Your patience is paying off, I like how you are taking your time and making sure you don't hurt yourself.
It annoys me when tennis players grunt when they play a shot. Now you have started doing the same when undoing nuts on the cylinders. 😄 I do understand and have often done the same, Just couldn't resist. Don't stop grunting, keep making videos please.
Great video… Tons of hard labor and money for parts💰
Use your baby tractor to lift the boom up and put a railroad tie under it to support the boom to take the pressure off the rod pins
Real Nice.
Yep the bucket cyclinders are always more likely to be damaged particularly on a machine of that age.
When I did the backhoe dipper cylinder, I cut a 30" diameter pine tree down and lowered the main boom down all the way and measured up to the bottom of the dipper boom and cut the pine log to fit under the dipper to support it. Yours looks like it would be too great of a distance to work that way but I thought I'd mention it anyway.
Maybe you can weld a temporary brace on the boom to hold it in place while you remove the hydraulicrRam, Matt ! Because it would keep it from collapsing ! Only thing I can think of brother! The best way to keep something from collapsing is to make it rigid! Maybe an A-frame on pads under the boom to support it! I was thinking about it and a heavy piece of flat bar welded on each side of the boom temporary so the boom can not hinge enough to remove the cylinder pin, I can picture it in my mind but it’s hard to explain my friend! Seems like it’s something I’ve done before in the machine shop where I worked so they could line bore the pin holes! It kept the two parts together for boring!Good luck my friend and good video Matt! Kirk from Louisiana sending prayers and good vibes to you and your family! Stay safe,warm and healthy this winter my friend! 🙏🏻🙏🏻🙏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👌🏻👌🏻👍🏻👍🏻👍🏻🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸
I'd put a good diameter log under the boom and then a hydraulic jack on top to lift the boom a bit.
Well, I think we have set a new high score for grunts and groans😁. I will definitely leave this kind of work up to you as I get a sore back just changing a tire. Hope the work continues to go well and stay safe..
Nothing but respect for you! You're doing yeoman's work without help and doing it well. Thanks for doing this series, really enjoying it!
Actually, I SMH at someone attempting to do that work solo - it's on the verge of stupidity.
Two men do the work of three, you should know.
Jankey, but hey, it worked!
Great to see another video! I know how much work these are to produce!
Hope you don't have any neighbors near by. I also hear a lot grunting groaning and puffing going on there. Lol. I thought only us old guys did that. Cool video. Keep going 👍
