- Had a damaged hydraulic cylinder on my Valmet 505 that needed reparation because it was leaking.
Filed down the tops, and filled the grooves with chemical metal. - Авто та транспорт
I know the machine shop has already been mentioned, but I myself own a welding/fabrication/machine shop and I also suggest finding a local machine shop to help you fix the cylinder. Next time you have trouble with the cylinder go talk to a machinist. Just ask them to make you a new rod. The rod is pretty inexpensive and comes already chromed so all the machine shop has to do is cut the threads on the end and they will be finished. No more than one hour labor for sure. Anyhow, I really enjoy your videos! And I wish you the best for 2020! Dan P @6-4 Fab Glen Rock Pennsylvania USA.
Dan p. I have a D-6 size JOHNDEERE 850 -BLT DOZER. both cylinders need. but left one got scratch ed bad with a steel beam. 256.
Text me with name/ phone# of404 shop up there in PA that can repair them please 8579. Here in alabama there are no such shops.
No history of those kind of people down here. (Old timers like that with own little shop.)
Ah so you can buy a chromed rod, Good idea will keep that in mind for the next time I need one.
Absolutt en forbedring. Den va jo ødelagt før du begynte, å du fikk den jo passeli tett. Å no har du jo prøvd å fikse den en gang, så da bi du å få d t neste gang.
Takk førr nok en underholdanes video.

Definetely an improvement. It was already broken before you started fixing it, and you sealed it some. And now when you've tried fixing it once, it'll be perfect the next time you try.
Thank you for yet another entertaining video.
I think the people commenting about the blue seal is the wrong way is probably correct, I need to flip it over and it's probably even better 😀
@@MiniMachines1 Æ trur du har rett i d.

I think you are correct, the blue seal should definitely be mounted the other way.
nice job !!! I had to laugh when the oil shot out !! because im always covered with something too before im done with whatever im working on !! followed up by the story of my life !! that didn't go as planned !! thanks for sharing !!
He he glad you enjoyed it :)
You are a handy man.
If there is a hydraulic cylinder repair shop in town they will probably already have a piece of piston rod left over from the repair of a longer cylinder. Get a piece with the threads already cut in it and cut it to length and weld your clevis on yourself. Many times you'll find what you need in the recycle bin. With the amount of Marine activity in your harbor there have got to be quite a number of sources for seals etc. All the hydraulic shops here in Dallas Texas buy their seals from a local distributor who can match anything you bring them. Its a whole lot cheaper than trying to buy a "kit" from a dealer.
Our town is pretty small so we don't have many speacial shops, it's more that one does a lot but don't keep a stock of a lot of stuff since it's money on a shelf. So for hydraulic rams I need to ship it away ore order it in. I guess if I flip the seal that I installed the wrong way this one will work for many years 😀
Very nice video once again👍🏻
Thank you 😊
you know it is done right when you do it your self, it saves time and $ .your channel is fine to watch your explanation is right on ,you have put the diggers in some hard places and always get the job done some people do not know how hard you work in the ice and snow ,look after your health and keep making videos.
Thank you :) Hardest part right now is time to edit videos, got some of them on the computer, but hopefully it stops snowing soon :)
nice job. looks a lot like JB Weld epoxy I have used. Might try taking off the high spots with a long fine stone to prevent putting a recess where you don't want it.
Thanks 😁 Don't know never had jb weld in my hands. Don't have a file stone so used what I got 😊
You can always go to a good "svarvare" (swedish word for it) metalshop or what ever its called in english and have a new piston rod made.
I bent the rod that drives the bucket on an excavator many years ago and then I did that and they made a new rod and welded the old parts on the new rod. Was no cost at all compared to by a completely new rod from the dealer.
What you did works to but if you want to get it done in the future its just a tip :)
It's possible but here I have no shop for chroming the rod so need to ship it away than and the price is probably more than a new one in the end. But thanks for the tip 🙂
@@MiniMachines1 What we did was get a chromed rod i the correct diamater, then cut it to length, thread it in one end with the "svarv" and then weld the connection that we cut from the bent rod to the other end.
Looking att the welds from yours it looks like that might have been done once already in the past.
I have a backhoe with a cut in the rod, im going to try this fix with chemical metal on that.
Quite nice job. But you did install rod seal (blue one) upside down. Lip goes towards oil. That's why it still leaks.
Yep I think you'r right, didn't know there was a right and wrong way so will flip it as soon as it stops snowing, day 10 now with a lot of snow 🌨
Nice work! Do you have the Video for the Tilt angle Display still on Plan?
Yes I only packed all my machines inside for the winter so I'm taking them one after one for servicing and will update that video when I get to the terex :)
Is something on the tractor binding the travel of the cylinder enough to bend the rod? If something gets between the cylinder and the transmission it will bend things as it goes thru its cycle.
No the rod is not bent, I guess the earlier owner have had something attached that have scraped the rod... But just guessing.
I really enjoy your videos. At 21:00, the lip of the blue pressure seal in the gland should be facing down toward the piston (toward the pressure side). I believe you put it in facing upward toward the dust seal. It will have to be taken out and turned over, or it will leak.
I think you are correct, thats probably why it leaks a little now🙈 I will try and flip it as soon as it stops snowing. Thank you for the tip.
Nice repair! I imagine that will last for a while.
I hope so 😊 if not I would need to buy the whole thing new I guess.
Yeah, or have a new shaft custom made, which might cost just as much
2:10 I see fresh paint on that tiltrotator, did u fix it ?
18:00 when i was fixing some small cylinder, i noticed when i use same tool as you, the seal has stretched.. So i started to use zip tie, and i put seals to hot water, they are getting more plastic to work with.. I talked to an employee at hydraulic shop, he told me they use special size tool for smaller seals and another tool for bigger seals.
Another thing is, u can buy chromed rod, they'll sell you the long piece you need, but somebody has to make a thread on it anyway.. In case of your cylinder, it got smashed pretty good. On my backhoe was a cylinder rod in bad shape, but not that bad ;d
No that was from the same time I made the last video about the tiltrotator, so no progress there yet. Never tried with hot water but will do next time 👍 yes it was bad but it's still working good after the fix so hopefully it lasts the rest of the year 😊
Interesting. I would have put the seal in hot water to make it more flexible before using the insertion tool.
I had a 2 metre ram made, piston rod tube barrel end cap plus 2 feeds seals, mounting brackets testing and certification all for €700. So I can only imagine it would cost you under €200 to have that short rod replaced with a new one... Even if you had to post it to Ireland or UK to get it done.
Not in Norway 🙄 and that is the other thing here is really expensive to ship out of the country 😕 I didn't get the price on a new one, the shop told me to try this first 😅 so I guess it's not cheap than.
What is the blue handle wrench you were using
It's an pipe wrench bought at an Scandinavian store, but you will also find it at ebay www.ebay.com/itm/Hook-type-Heavy-duty-Pipe-Wrench-Pliers-Adjustable-Spanner-Plumbing-Hand-Tools/352771673067?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20160908105057%26meid%3Dedaca25c67a948bcac50da6175fb5501%26pid%3D100675%26rk%3D1%26rkt%3D15%26mehot%3Dnone%26sd%3D352771673067%26itm%3D352771673067%26pmt%3D1%26noa%3D1%26pg%3D2380057&_trksid=p2380057.c100675.m4236&_trkparms=pageci%3A444a7152-4726-11ea-96c5-74dbd1807b49%7Cparentrq%3A0f4331a51700a4d0e1a51103ffec86ce%7Ciid%3A1
I have a cylinder on my scraper that creeps down but that is because the tube interior surface has a bunch of rust cavities in it. No amount of honing will smooth that up. The only solution there is have a new cylinder tube made or buy a cheap replacement. I'll use it until it bothers enough to do something about.
Ouch that was an worse problem, I see that here in Norway the universal new ones like I bought for the homemade tiltrotator is cheap, but when you get an special made one for one machine they get expensive.
Those rear tires will be due for replacement perhaps in the spring ?
They have a tube in them so could last a long time, all 4 are just as bad 😏
@@MiniMachines1 yes they will stay inflated since the tires are tubed , but at some point the rubber is going to start crumbling lol
Or lath it to a size that would match a tighter seal.?
Like oversize piston rings in a bored cylinder?
It's possible but it need to be chromed to not rust and there is no shop fore that in my town.
I think you will find that the rod is Chrome-steel... i.e. Cromed all the way through.
May I ask where you purchased that big channel lock pliers (blue) we call them channel lock pliers in Northern America. I want to by some. Great work brother.🍻🍻
I bought mine in an Scandinavian store called Biltema, but you will find similar on ebay: www.ebay.com/itm/Hook-type-Heavy-duty-Pipe-Wrench-Pliers-Adjustable-Spanner-Plumbing-Hand-Tools/352771673067?_trkparms=ispr%3D1&hash=item5222d48beb:g:4IQAAOSwi8NdgvOJ&enc=AQAEAAACQBPxNw%2BVj6nta7CKEs3N0qXOApg5USJhNdQRyMYl4jn9gfdABQ1bx393DTBm9NAiUdrrLfL%2BVKzdFQ1FKiggQiCpqCMnUxJAM%2Fnp6%2BjuNSpOYScaBpZEoQnEzl3BC4MfxVXT8FPzq9cct9caMWnV0RVvFzuQxDfPi8fh5dX49O6q1HGUpL7KgxqFmZD23j%2BnMZAm%2FokEawEMx0HMR7heqNRmj7VVzK0xfKEktwS7S9WP15MP5evThUgd57m8p7%2F6KOe7PBSwg9Due0lUUEG7YCRZjMHY1%2F5fKRm7CBy83glKjvIbAwxdB%2Fh3f7SZiedIFl6iGxlAfdTgbt1sOz0GrNUdMZU6h6vMVDWyxtU8HFkjrO8o12BIhfYk89t7o73rN6AfF%2Fx8yPrBlmaMjLGHXrgECr59rF0V%2Fd6NkwSd%2BMNxdrCMCnioFnznz9jL8C75TneHZhv0b5gff5ZfTFpJOLrRvf55D%2FFE9lHNl0jg%2BUPzPwYAIKvlfeI8xEhJFhE%2FHlR4BxzKUp4KPtHRCBcHxPICxBFNAFc37FT1Ue7xMAGj5dBUJoS9t%2BUb1aUY66iXgEdQs0NYkF64xRBXSx4lw12APtdStZpm2CWkAaeFvC1aoH%2BAZowDSD1MrxMcsz9w4z7stPGdE8MjMMSNGZEOYZVJXV10N53PstVg74btvjcOMjx2je8%2Bk9oMEWGY%2FbGExkrp%2FmGHJUUOMrghOtoqq5tZn11VYPBvo5WdGUY6awKjupWbEBB3J2uWusg4sAEqLg%3D%3D&checksum=352771673067134b015073eb4f2fadeb4df1ee3fc061
Når jeg har byttet tettninger og oringer i sylindre så putter jeg oringene/tettningene i en vannkoker. Da blir dem mer elastiske og lettere og montere. Lite tips hvis verktøyet du kjøpte blir for stort osv. :)
Takk for tips må prøve det neste gang😊👍
Not a 100 percent sure cause it’s hard to see but the blue seal is up side down witch is the reason the cylinder is leaking the way it is after a month of being on the tractor. Nice job on the rod. I always used supper clue but mite think about using this method.
I guess you'r right, got some other comments on that so will try and flip it when it stopes to snow.
Sounds like the pivot points for the three point hitch need a bit of grease to reduce wear and operate smoothly
Yes they have gotten an round of grease now👍😊
Yes the after repair clips it sounded like things were much better.
Better on the jacket than the wall with tools.
Yea thats true, When I'm sanding the noise in the background is the washing machine with the jacket in it😅
A long time ago I had heard of people using a special welding rod to repair cylinder rods. I'm not sure how well that would work on chrome plated though
You probably could do that and use an lathe to get it down to tight size again, and than chrome?
🙂If I was there I would have said look out for the oil.
He he well now I also know about that 😅
I'm not 100% sure, but i think you put in the blue sealing upside down. For me it looks like you put the open side outward and not towards the pressure side.
I think you are correct, thats probably why it leaks a little now🙈 I will try and flip it as soon as it stops snowing. Thank you for the tip.
Why can't you get it rechromed?
Re chrome it to slightly bigger ( .02 oversize ).
Unless its bent, it should last 20 more years
I don't have the shop for chroming here.
put on safety glasses it is easy to loose an eye if you do not.
Ask a Machine shop to make a new piston for ya 😉
We don't have any shop here in our skal town that can do the chrome on the rod.
@@MiniMachines1 but you can buy hydralic rods in any lenghts diameter etc etc and then just ask a Machine shop to weld a new ear on and and tread the end on it. We do that alot when we damage a Rod, we just cut off the ear on the old and weld it to a new and tread the end on it 😁👍

For exampel 😁
I Think this Wound ne tze best typ of repair. Because the chemical metal gets loose after a while and then you have the same Problem again. But for a short period of time the fix is better then nothing.
Please don't add that awful music. It spoils your nice videos.
Thanks for the feedback, I'm afraid the time laps that has no audio gets boring, but will try to find som easyer listing and turn down the volume more on the music?
