Abandoned Backhoe Rebuilding - Does the Diesel Engine Run Better? Part 8 

I would say by sound you have a bit of a burnt exhaust valve. Roll from cylinder to cylinder add air through injection holes and you’ll find it coming though the exhaust.

It does sound better. That looks like a Roosa Master injection pump. I've seen a number of these that have kind of random poor running issues due to the flexible coupling on the fly weight basket for the governor inside the pump failing. It's a very common problem. There is an updated 1 piece coupling that eliminates the issue for good. You seem pretty handy, so you might tackle the job yourself. An injection shop can get you the parts.

Ask "Western truck and tractor repair! Warren's a fine diesel guy! Very knowledgeable! If you don't find the problem yourself that is! Good luck

There's no doubt that it's running better. Before the whole thing was shaking but now it's solid. Well done, pukka job.

Use to run a 580 B back in the late 70 early 80's. That sound brings back a lot of memories. I very seldom did any work with it full throttle, usually about half and it always was a joy to run. Really miss it.

The return line at the pump has an elbow fitting on it if you remove the fitting there is a glass check ball that is spring loaded the underneath of it can get gummed up especially on a machine that has sat for a long time. It stops the extra fuel from being able to return to the tank which causes over fueling. Take some carb cleaner to it and get it cleaned out where the glass ball will freely bounce up and down then put the line back on and see if that doesn't help it smooth out. I hope this helps ya man.

Lots of things to fix. You will get there. Thanks for sharing.

Yup, she definitely runs better - but to me, it sounds like the exhaust manifold gasket is blowing around at least one port. For the price of some Knock'R'Loose, a few minutes with the spanners and a new gasket (or set of gaskets? Not sure if it's one-piece or individual exhaust gaskets per cylinder), might be worth eliminating that from the checklist. Keep the faith, she'll come good in the end :-)

I do have a field fix tip for you: get some cardboard,a piece about 2' x 2', and put on the ground when you're working on something with small parts that the ground will eat or at least hide very well from you. Saves a lot of time looking for that dang nut that fell "right freaking there".....If working on a concrete slab I put an old towel down for the same reason: had nuts roll away at least several feet then on my hands and knees looking for that odd-ball metric blankety,blank,blank nut.

Nice job dude. I have a 580 super e that was in about the same condition. Repacked all the cylinders and replaced a shitload of hoses. Works good enough for me but “good enough” is the standard at my house. Really liked the straightening of the rod video. I’m gonna bend mine on purpose just to use that technique. Hillbilly McGyvers rule!

Gotta check those lashings at Top Dead Center and make sure that the intake and exhaust have their own tolerances

I like your attitude, “Fix only what needs fixing”. Sounds like it’s running much better! An engine that old is gonna have a little miss in it but run just fine! You’ve done some really excellent work! Hope you get the PS and brake(s) working the way you want them on the next try. Fingers crossed for ya!

For what you paid for it I think it's a great piece of kit, I don't think many things are faultless and sometimes we don't get it fixed properly or cheap parts are not as good as they should be or faulty from new? There are all sorts of possibilities when we take on Challenges like this and you always have to default back to it was cheap and someone else did not feel it was worth spending the time or money on. But for me, I enjoy the challenge immensely especially when you're doing all the work for me to enjoy? LOL Thanks for taking the time to make the videos as they are helpful, But always remember each piece you fix is one less that you have to deal with, and from where I sit you have done an amazing job. It is good to know if you are having ongoing issues with the brakes and that is strange that the problem followed you from one side to the other. Cheers From Garry in Australia

Snap On make those wrenches, they are extreme quality, they actually where out, eventually... instead of breaking. They fit in tight places and you can use a Vice Grip wrenches to extend leverage without any issues. Use these to pull motor bikes apart!

Even if you have to throw a few extra parts at it you are still way ahead !

Sounds just a little better. Still sounds as some missing is happening. Good effort

I was given a set of those wrenches when I graduated out of high school in 1974 and your right I haven't seen them for sale in years

Infrared thermometer also works awesome for finding weak cylinders

I've been enjoying the series. Always love to see old Iron brought back to life! I hope you find yourself a Dip Stick for this soon..that plastic bottle drives me nuts ! :-)

G'day.. Thanks for sharing the progress of the machine .. Looks n sounds much better ...however the engine still seems a little rough .. if it's not compression or timing then it's a dirty or worn injector . Spray pattern is CRITICAL for combustion .. Your almost there ...go go go Respect from down under

like your videos Mike but please work on your sound. very quiet so I crank up the volume then all of a sudden its so loud it blows me away.

On my old case starts to run rough I use injector cleaner and it helps. If you suspect bad injector switch it out with another cylinder and see if it follows it

Do you have a point-n-shoot thermometer to check the exhaust runners for a cylinder running cooler than the rest? You can also use cheap white paint on the cold runners and watch if the paint cooks and discolors evenly as it warms up. Soapy water works too for checking from cold start and idle while paint is better as the motor reaches working temp. It's easier to WATCH all cylinders for change than doing the hand dance.

Sounds good to me. The Case engines had a lope and I like them over the Cummins. Cheaper running. As for pins, just run used oil over them and sometime they'll blow through without taking them out. And I like that Chucktown shirt!

Run better? a bit. Old equipment can become an endless repair. Question to ask is does it run and work as expected without destroying itself.Bought,repaired,sold or kept 20+ farm tractors,5 dozers,crawler loader,4 backhoes... If they function as they should,run in normal coolant range,have good oil pressure,little to no blow-by and are safe to use I call them good to go.On yours you could pull the head and send to a machine shop,do an in-frame,replace all injectors,re-build the injection pump. Might as well pull the radiator and have it cleaned,install a new water pump the t-stat too. Or call it good and go dig stumps etc and deal with a slight intermittent miss.....

That was really neat watching you weld by yourself.

It seems to be a random skip or misfire. I had a Chevy with a worn bushing in the distributor that did this. I replaced the bushing in the distributor and it ran very nicely after that. I wonder if the injector pump has a worn part that is giving bad timing to the engine. I'd pull the injector pump and check the gears driving it for play, check the gear on the end of the injector spindle for play. If something is loose inside the injector you might be able to replace it or at least tighten it up. Otherwise it seems not to be smoking which indicates that the injectors are working OK.

...good job, comin' along great. sounds better...good luck with the rest of the resto...

wow it was amazing ,,watch the all vids ,, bravo it help me in my quarentine for the virus .. i am ok and hope it is the same for you and your family mm again thank you from canada 29 of march 2020 guy from ottawa canada

Have you asked anybody on the Heavy Equipment Forums under the Tractor/Loader/ Backhoes sub forum about the rough engine? Some participants over there have always been helpful to me on my Case hoe.

Used backhoes tend to turn it's owners into mechanics . Good job .

i sure have the impression it runs smoother! congratulations

I think it’s sounding really good

Is this one of those tractors without an engine computer? Those are nice because you don't have too much electronic bulshit. Issues

it is running better but I swear that sounds like the governor or something isn't having it run at a level speed.

Definitely sounds better! You're doing a good job! Keep it up.

Remember The Rule of 9 when doing the clearances.

Enjoy this channel. Try doing a compression check yet? If not, give it a shot and see how your valves are doing. Good luck.

the valves need adjusting in sequence to proper gap using a screwdriver spanner and feeler gauge BOb1066.

If you have a book for this engine read up on the procedure for setting valve lash I am no mechanic but it didn't look right. good luck

Is as a good Idea to have your diesel injectors tested to see if the spray characteristics are good

Sure have enjoyed this backhoe series.

I think it is running better. By the way, you missed a spot over there with the power wash.

Definitely sounds better, might still be missing a bit but hopefully will improve with more hours (No.2 cylinder might've been "lazy" for a long time so probably gunged/gummed up), unlucky with the brakes saga though (always a pain having put it back together only to find another fault not apparent when initially working on it).

sounds better Mike.

DID YOU BRING EACH PISTON TO TDC ON THE COMPRESSION STROKE BEFORE YOU ADJUSTED THE VALVES ON THAT CYLINDER ? I DONT THINK THIS GUY HAS ALOT OF EXPERIENCE WITH HEAVY EQUIP.

Sounds good, waiting on the next vid alreaady.

sounds better

Sounds good but someone put a 15 series fan belt in place of the 17 series belt.

It sounds like there's a leak or a crack in the exhaust manifold.

Needs injectors checked or replaced and the pump rebuilt.Ask your local heavy equip mechanic who in the area rebuilds them. I also happen to own 2 case 188s and mine sound alot healthier.There is a small chance of valve leakage,but highly dout it..

Mike you are having those “wth” days and I hope you can finish those needed repairs. I think you will need to load up the engine by digging with the backhoe and then moving dirt with your front bucket to test the engine. I’m not sure if you said you swapped out number two injector or not?

I've got one in Australia

And by the way, like the intro time stamps.

Yes, it6 sounds better to me -WoolgoolgaNSW Australia

I think it's running some better

Swivel head..still make them,good tools

Mike, it still has a skip to it and like a person mentioned, check for even heat on cylinders as a piece of carbon or what ever could be the problem. You say it set for a while and its likely that you need a valve grind to fix it right but then where do you stop at. It may come out by running a while or finally just get worse and then you can find and fix. I don't know if that has the baby cummins in it or what but if it is then taking heads off and grinding valves is a full days work if everything is in your favor. Right now with winter knocking on the door so spring has its blessings unless you have a place out of the mud and muck... good luck as I hear frustration in your voice. Normally and I know that you have worked on steering, it ain't hard to solve the issues but without being there I am just a arm chair jerk

It could have a weak piston return spring on its way out?

Don't you have to rotate each cylinder so it's TDC of the compression stroke before adjusting them? I don't know anything about diesel, is it different from gas?

Good fixes, i learned a lot

Its the injectors I know I work on these machines all the time

Nice series Mike!

Your audio levels are fluctuating up and down.

The exhaust sounds like it has a leak, a crack in the manifold would cause the engine run ruff..

maybe all new injectors ?

And by the way very good videos ,keep up the great work

ya kin look at it this way. YER FURTHER ALONG THAN WHEN YA FIRST FOUND IT.

Does sound a little smoother to me.

well i could say you did this wrong and that wrong(but im vary impressed)from the first to the last vary good vids.MK KEEP UP THE GRATE WORK

Sounds better to me but I think I hear a valve or injector sticking. Intermittent knock. Could also be my imagination.

If you want onlymake test so witch 1st and 2nd injector. Than make the same test. If problem will still on 2nd cylinder, injector is OK, other way you know you have to buy new one.

It's difficult to tell how it's running from the sound on a video. That machine appears to have been on a zero maintenance schedule and severely abused. You might have to compression check the engine, do a cylinder leak down test or pressure check the pump.

keet up the good work

Adjusting valves has to be done methodically. Learn the procedure and do it right. Half-assed gets you no ass. If you don't do it right it will make you think you have problems all over the place. Great videos but you have to be cleaner when messing with hydraulics. They can be very unforgiving.

The engine performance can only be judged under load when working hard. It is bound to sound better as the bad fuel deposits are flushed out.

What you working on

sounds better...be a good yard dog to have around your place ,with not much money in it...cousin has one just like it....you must be a mech on heavy equipment..you seem to be seasoned

Running much better

your sound is a bit soft and then normal from time to time, good video for the rest check your mic

It still sounds like its missing.

run a compression test on all cylinders

WORKING.

Arriba los Hillbillys ..

That fire could have solved all your problems...

What. Year is the 580 ? I had a 1975 480 B yours looks slightly newer

Your audio mike is way too directional. As you change your head up down and side to side the volume jumps and dives.

Id say there is at least 1 more bad injector. Check them all again

better, but still not right. compression check will point the finger

Does excavator equipment of this age have ODBII systems, to help diagnose engine performance? RL

To bad cant read your messages Red type doesn't work You should have caught that when you edited and typed it in Try. WHITE next time

Well she’s running a little. better but I feel you have a bad valve on that second cylinder

New shit I command injectors off, old shit use a inferred heat gun on the exhaust manifold.

Gosto dos seus videos, pois tenho uma retroescavadeira Casé 580h ano 78 parecida com a sua, e gostaria que vc colocasse legendas em português para que eu entendesse o que vc fala, pois seria de grande ajuda para mim! Valeu, Abraço irmão!

Sounds as if it may have a dead cylinder ma have washed the number 2 out

It's still missing

Boy, i sure do cuss a lot more than you when im working on my old 580ck. Thats an odd one on how its running. The audio does sound like a miss. Damn near impossible its a burnt/broke valve/seat because atomized, unburned fuel would be coming out of the stack in a white cloud. Also the nozzles (those arent injectors- technically) when they go bad, USUALLY dump fuel in the cylinder and itll black smoke like a bastard. I wonder if youre pulling air on the suction side. Or possibly a nozzle is seized shut...rare but it happens..ive seen it . As far as injection pump timing being out, that wouldnt cause just one cylinder to miss. They'd all be off. And for the timing to be "out" it would mean really bad tooth wear on the gears....nah. You can look for air in the fuel system by placing a hunk of clear hose/tubing on the return line. You can return the fuel in a bucket id easier than going "inline" with the return. If you see a crap load of bubbles in the line obviously youre pulling air. Ive been cussing at diesel engines professionally for too long to care much anymore, but just trying to help. Good luck buddy. Cool videos!

Idle is too high.

No

No! It's not running better in my point of view
