Those cylinders with the rust are pretty rough. At minimum I’d run a hone in them and check for pitting. If they are too far gone they will continue to cut the sealing rings.

It has caterpillar like effect, very solid feeling

Best part: whenever it's moving heavy earth, she bog down seem like she gonna shut off, nope

She keep churning earth 🌎

Carve you earth for 10-15 hour, shutting down when hot

20241129_112012.jpg


Carve you serious amount of earth with L295DT

Make you one statement:

These machines way better than modern skid loader and worth twice as much in gold/cash because:

Your normal state when you churn earth is NO INPUT from operator, meaning

Put you that gear, drop you that cluch, and she is churning earth and you are just hanging out

Compare that to the modern skid loader:

It needs INPUT from operator at all time when it is carving earth

IE: all skid loaders are inferior/annoying

Real ones working in the field understand

20241129_111934.jpg


Cold, she run fine and no issue

When she get hot, I notice bigger leak from this area, diesel line from the tank to the engine, I think the valve that close the tank is leaking

You are moving serious earth, she is getting hot in temperature, this line lose its prime, and engine sputter off

seal you that area next time you do service

20241129_115424.jpg


glob you some gasket maker to try to give it better seal temporary

20241129_132310.jpg


install you semi truck battery you got for $20

20241129_145346.jpg


change you the shape of your realm

20241129_145357.jpg


exact pattern before she sputter out:

smoke start to come out this vent once she get hot then it is likely to die off under big load

few possibilities: there is only water in the engine, no coolant, maybe coolant keep it lower temperature

the diesel line: suspicion: that line from tank to engine need to be fully sealed or else engine will pull in air pockets and sputter out

20241129_162456.jpg


there was no problem but the hydraulics, bucket stuck scraping ground, and engine cant drag it,

drag you back L295DT to the shop, fully attack all the issue:

Take you off all hydraulic cylinder, do surgery and try to seal them with gasket maker, and

address all other hydraulic leaks, when I look inside transmission, the fluid is bubbly, meaning

you are pulling air into the system from somewhere

seal you up all your hydraulics, fill it up with fluid

Rebuild all hydraulic cylinder, seal up hydraulic system

20241130_095737.jpg


20241130_095759.jpg

20241130_095829.jpg


I point here to the ring that hold in the cylinder, last time spent too much effort dealing with it, maybe my protocol wrong, my protocol:

seal up the cylinder, then hammer the ring in millimeter by millimeter, takes too much time



is the protocol:

put ring in then close the cylinder over the ring, it will take less time doing this

let me know which is correct

take you off all 4 cylinders, take them apart, clean them with intent, then

glob you bunch of gasket maker to seal where the hydraulic fluid oozing out

from what i remember and the looking at the diagram, you can seal that part where the cylinder moves up/down, there is rubber seal there

if gasket maker cant seal it, then get you the proper seals made for them etc

Also, your plumbing that you did on the hydraulic system is causing air to get into your lines, and its causing your hydraulic fluid to bubble up

I do notice I can work hydraulics when cold, but after a bit the pump start whining, and if you look inside transmission, you see bubbly fluid

figure you out where the leaks are in your plumbing, maybe melt you some bronze on the leaks

20241130_103353.jpg


you notice fluid all over injectors, you might've found your loss in diesel pressure that cause the sputtering down

20241130_103436.jpg


you notice big crack in your 40 year old loader

20241130_113629.jpg


no way to take apart cylinder without removing the ring, almost destroyed it trying to air chisel it

got your cylinder apart, I point to the leaking area

20241130_113645.jpg


to get to the leaking area, unscrew this part and the rest of it should come out

20241130_120757.jpg


almost destroy your cylinder trying to get it unfastened, look at diagram again maybe there is a better way

figure something out where you get something hold on to it tight, then hammer on that

20241130_123116.jpg


yes, you found a way to unscrew top of cylinder

put one side back onto the bucket, now she is hold tight, you you massive pipe wrench, torch hard soak in diesel

tired of dealing these 45 year old leaky cylinders, destroying them trying to fix them, so grateful that you got them apart and can move show forward

might've found a way to save big $$ by rebuilding your own cylinders, rebuild your cylinders try to seal them

20241130_123816.jpg


so grateful you got it apart, and you can see the pathway of the leak, dirt trail going through all the seals

clean you everything surgically, get you gasket maker and build back with gasket maker and clean seals and let it cure, do that for all 4 cylinder

20241130_140810.jpg


make you workstation out of pallet, clean everything with solvent/air, take you out all the seal, who care if some break, gob everything in gasket maker

keep you going, taking them apart, sealing them up in this way, and sealing up all the fitting, anywhere there is hydraulic pressure, you seal

20241130_152325.jpg


show you before you close up the cylinder

one done, 3 more to go, your close to having your robot functioning

20241130_180126.jpg


Lift cylinders are welded on, grind everything down, hit hard with small torch and maybe big torch, sledehammer and big chisel, get you out one pin, get in there and do surgery on both cylinder

@north wolf

yes I listen, I have not pump hydraulic into it yet, let it cure, i was fixing to remove lift cylinder

ok i see what you mean, hydraulic fluid will break it down and flood the system with small pieces

20241130_184617.jpg



hit you both pin with grinding wheel until you see separation, then soak in diesel, hit hard with torches, smack with sledgehammer

20241130_195957.jpg


take you out 3rd cylinder to rebuild

20241130_200020.jpg


I'll never understand this ring, got it fully stuck inside cant open up cylinder

@dragfan66

yes, I see that now, I just grinded welds for an hour or more for nothing

This has turned into a 100% over the top train wreck.

For any poor soul that runs across this thread, this is 100% a DO NOT DO ANY OF THIS THREAD!


ALL that RTV running around in the hydraulics system and transmission is going to mess everything up and you'll have even more issues than you can ever deal with.
The RTV will hold for about a millisecond before it jettisons off into the valve, the transmission, the gears, the filter and the pump!

Too bad you didn't take that bolt out adjacent to the pin weld you are grinding on.
That is what is holding the pin in, not the weld.

I hate to say it, but this project is getting way worse instead of better every day.
The silicone is going to finish off the hydraulic system.

I’m thinking Joe’s laughing his A** off. Will he make it to 1000 posts on pure BS? Its obvious he does whatever is the most detrimental repair in every instance. What other reason could there be other than the entertainment value?

Well, it was predicted by many at the beginning of this thread that the tractor engine would never run again. But the tractor is pushing some sand around today.

In a way this thread is a testament to the value of sweat & hard work, at least in the short term.

Amazing to me, but when I think back on what has been done to the tractor during the term of this thread, I’m having trouble remembering anything that I would do the same way! I honestly mean anything! There must be something…

Perhaps time for another challenge: "What did Joe do that you would do?”

One thing I give Joe credit for is he cleans things thoroughly before he does his duty to them.

Another thing, he takes a lot of good pictures of his work. That takes patience. I almost never stop to clean my hands to take a picture when tinkering on something.

complain you about every leak until all of them gone

20241202_092203.jpg


Your hillbilly plumbing still leak tiny bit, give it that big flame, do you some magic until it is melted into intself sealed

20241202_092216.jpg


your connection to the transmission leaking, 45 year old seal clapped out

glob in gasket maker

20241202_092304.jpg


I see leaks on the bottom of where you connect your cylinder to the valve

something with the fitting is not right, dont worry about figuring it out,

label you each line 1 through 6, take you off all the line, take you off all fitting, clean everything then compress air

glob you ton of gasket maker, you seal up all fitting with militaristic intent,

build it back up SEALING EVERYTHING and put your lines back in place since they are labeled

20241202_092317.jpg


glob you up gasket maker on connection of pressurized transmission line

20241202_092342.jpg



diesel leak: try to see where it is located or take everything off and build everything back up surgically sealing with solvent/air/gasket maker

the leak definitely big enough to cause your engine to shut down at normal throttle

20241202_092438.jpg


your other hillbilly plumbing somehow not leaking

20241202_093025.jpg


coming off the hydraulic pump, leak also there, seal it up, seal clapped out

20241202_092525.jpg


the ring inside the cylinder giving you big trouble, challenging you

that little ring defeating you, it really is

get you a cut off disc, cut into it, get a nail and hit the ring until it come out toward you, go in there with surgically stuff to pull it out

that ring is the reason why people give up and get new cylinder,

get you inside that cylinder and do you the surgery to seal it

summary: you declare all your leak, then you attack all your leak, and rebuild you the two cylinders with escalated effort on that ring


first task you do, witness you some magic

dont play with that big flame in the worldly state, only play with the big flame right when you wake up

20241202_105558.jpg


hopefully your magic trick seal your hydraulic line

20241202_121406.jpg


consume you your entire existence/energy/might into trying to get this ring out

an absolute nightmare, i FULLY AGREE with the detractors that say this is all a bad idea, all of it

got the ring out, rebuild cylinder

20241202_125611.jpg


proof of flaws:

I just spend 2 hours hammering like no tomorrow, cutting, sparks are flying from my strikes

only to find out, all you had to do was spin the cylinder and reveal you the ring to grab, and yank on it and spin more and it come out

2 hours of maniacal destruction for nothing, unbelieveable

20241202_150928.jpg


entire day of energy gone and you still have not separated cylinder

I bet there is a really smart way to do this, you would pump pressure into the side you want to push and it would pop it out

fill it with transmission fluid and acetone, leave it alone, go take off other lift cylinder

20241202_154956.jpg

no, come you back out the rash state, come you back to the reasonable state

stop hammering, chain you up both side, pull on cylinder with pickup truck

20241202_155137.jpg


Separate you your cylinder, unbelieveable

rebuild your cylinder while you ponder -

why did I waste all that energy? Why do I forget about the methods that I have already discovered?

20241202_162013.jpg


just unscrewing this took big effort, big torch time, tons of diesel

20241202_162937.jpg


20241202_173645.jpg


take off everything, clean and reseal, put back onto loader

20241202_180510.jpg


cannot screw the piston head back in, fully defeated, unable to stand

grind you down those threads to let it screw in easier

you wasted ton of energy incorrectly, you plan to do 10 things, you didnt even get one done
