Two free tips on the DEUTZ engine. Hot pressure wash completely the interior of the engine, cylinder liner fins, oil cooler and cooling fan. This is a MUST to keep the operating temperature of the engine under control and not to size a piston. All should be completely clean 100% without any grease, dust or paint.. Second tip: when you operate a DEUTZ engine you should keep the engine speed ALWAYS above 80% of full throttle rpm. If you operate it to slower peeds, the engine cooling fan will not provide enough air to cool it and you will overheat the engine and seize a piston. Bonus: always keep all air cooling compartment covers and seals correctly positioned for not to escape any cooling air and all the air goes through the liners and cylinder head fins. Enjoy your Liebherr.

There is a “no spill” adapter that threads onto those fittings, that has a hose on it, so you can eliminate the mess, as you thread it on, it opens the valve up, they are crucial with nasty diesel oil. Not gonna lie, watching you take an oil bath had me laughing! Great video!

As mentioned about keeping the engine clean, there is an access cover on the side of the engine to clean the cylinder liners . Secondly Always keep a spare fan belt as they take a lot of abuse . Also, ALWAYS ALLOW THE TURBO TO COOL DOWN AFTER A HEAVY USE ! you should idle the engine at least 5 mins .Always change the inner air filter with the outer .

When you change out the teeth. You aught to consider hard facing the side of the bucket. This will help give longevity to the bucket, and it’ll give you another skill in welding. Plus with all the rocks you’re going to have to move it’ll certainly keep the bucket more usable longer. There is actual hard facing welding filler, but I’ve also seen folks just use a standard 70 series rod/wire. Hope this helps! Love the video

as a German and a mechanic, daily working on excavators and sometimes old Deutz motors this video has me smiling. keep up the good work you have a very reliable machine there

Hey so I’m a apprentice in the heavy duty mechanics field in Canada and whilst I mainly work on semi-trucks one thing we learned in class whilst learning about tracks and undercarriage for equipment such as yours is that it’s a common misconception to dig on the side as you were. The machine is actually meant to dig from right on top of the front idlers. Whilst you can’t do that in every situation and I’m not bashing any operators who do dig that way it’s been proven to accelerate wear on the undercarriage components such as the bottom rollers and sprocket. Just good for thought. Cheers

Great video! Looking forward to part 2!

Luv the video... Cant wait to watch part 2! “Big Bertha” or "Fritz Vator" are 2 names that come to mind.

Word of advice, when prying on big rocks always try to keep the bucket on the ground and pry by curling, prevents unnecessary strain on pins and is easier on the machine, absolutely loved the video 👍

I am an old Diesel guy, heavy duty lubricants guy. Story: In 1990's on Long Island, an air cooled Diesel same as yours in a rock crusher was turning motor oil to tar. They first blamed our motor oil (of course) we went out to have a look. We found that the plasic blade cooling fan had passed so much grit-filled air that it widdled down to nothing it no longer passed much air and the engine was toasting it's oil. (Before hydro cracked base stocks I guess) So, have a look at your cooling fan and make sure it is good as new. Maybe depends upon the region. The ducting/sheet metal shroud is also very important to force air to coolers. Don't let anyone run the motor without it. Seal any gaps to force all the air through the coolers. Also, feel the exhaust manifold near each cylinder during a cold start to see if all reach temperature similarly and you can tell allot by that. New hydraulic fluids are better and so are greases. A good moly or graphite grease matters, high tack helps too. Seal conditioners in some hydraulic fluids can help restore valve seals and piston seals. Tranny fluid works pretty darn good too. Some folks even use motor oil in the entire machine. Manufacturer has recomendations but those are long outdated. Synthetics are a great way to go whenever possible especially in a machine that sits. Keep a 55 gallon drum of hydraulic handy. Also order hoses ahead of time, maybe learn to make your own. Check any rubbing points. Make sure you reinstall clips and isolators and and ad if you have to do any wiring. Anything touching the motor or frame can be short lived. Diesels will vibrate through wire insulation, hoses and fuel lines quick. Thats why so many clips on those fuel lines, there for a reason!

Good that the parts are still available, and the machine is of a vintage that doesn't get obsoleted for lack of electronics and software :-)

Hanz for sure. Very entertaining especially because I’ve never watched anything like this before. Thanks!

As someone who’s been around large equipment all my life I can say you are doing exceptionally well for your first time👍🏽

Whenever you can, you should dig with your tracks in line with where your digging with the track idler's in the front. Wont wear out your tracks and sprocket as quick. Happy digging from the 603 aswell!

What an awesome video. My eyes were glued the whole time. Instant sub.

5:50 Geez, that really puts it into perspective the size of this unit. So far, it looks like you scored on this one, no blown hydraulic lines or other obvious major issues. I'm used to seeing the stuff Matt (channel: DieselCreek) buys. I really like the metric units you add to the video. So I was right; it is turbo charged. I kept hearing what sounded like a turbo every time you stopped moving the excavator.

There’s nothing quite so satisfying as taking something that is old and needing work, and fixing it up to workable condition again. Great video!

Because of fluid mechanics (of dirt lol) that boulder will rise back out of the ground over time. I would recommend moving them rather than just reburying them. or put them a little deeper into the ground.

That's one of the most wanted and awesome versions of this engine. Well done.

Lol youre so funny with this oil change 😂

Great video. First time watcher here. I’m a heavy equipment mechanic in MD. If I could give you one piece of advice whenever digging especially something hard like a rock position the tracks so you are digging over the idlers and not the side. You don’t want to dig over the final drives (planetary gear boxes with the sprockets) because that shock can hurt the bearings and gears and they are not cheap. Keep up the good work

Name the excavator Hans, because Liebherr was founded by Hans Liebherr in 1949. Greetings from Germany. Btw love your channel.

This just came up on my recommended and loved this video. I want to show my nephew. Very surprised after 10 months no update. Giving a follow so i can get an update.

"I'll be back" - the rock he just burried

Yay Deutz! My late father was the second Deutz dealer in the US! They can use 10-15 seconds of glow plug pre-heat and will start instantly regardless of temperature. Use a pressure washer (or steam washer) to blast off that buildup. The 913 deutz engine line is ultra reliable and can give you 40,000 hours of use if you keep it clean (cool) and feed it clean diesel fuel (good filters). I had one irrigation pump that I overhauled at age 18, and many years later, the owner brought it back with over 50,000 hours more runtime... The big air pre-filter can be cleaned by tapping it on the sides on a flat surface. Rotate it around, gently tapping the filter on the surface.

I'm not exactly sure why KZfaq recommended this video to me, but I LOVED it and can't wait to watch more videos on your channel. I think the last thing I needed was another channel to be obsessed with, but here we are!

Good buy! Sounds great. It will really co.e in handy

I'm loving the mental image of an operator getting frustrated with the seized throttle lever, putting more and more force into it until it just snaps off with them holding the broken piece up with an 'ohh shi-' look on their face lol.

That engine is a gem. Had an old worn out one back in '95 used in a scrap yard....got that 6 pot air cooled diesel running a treat......tighten heads...they work loose and reset tappets.....easy! loved it

I just came across this video and it is the first video of yours that I have seen. I own my own excavation company and can tell you that a hot bath is not necessarily the best thing to remove grease. If you get a pump up pressure sprayer and put diesel in it and spray the entire tractor off with diesel, it will remove the grease instead of spreading it. If you repeat the process twice, you’ll be pretty clean. Hope this helps.

Man what a great video. Good job.

When is the part 2 going to come out?

I am 74 now. As teenager i was equipment operator an did some repair. When in my mid twenties to mid thirties, I was a heavy equipment mechanic. I bought several pieces of heavy equipment and repaired them. Wonderful hobby, repairing my own equipment. In mid thirties I realized it would be very hard when I got older it might be too hard to continue. I went back to school and learned computer programming. I retired with twenty plus years in computer automation. Since my retirement I learned to buld apps. I freelance now.

A bit of advice, when excavating something as large as a bolder have your track facing it straight, and not sideways with it, you can tip over an excavator that way, it jumps a lot and, also, the idlers to the back to keep the weight behind the machine. PS: Just noticed that the excavator is also leaning towards the bolder as well on a slope which makes it even more prone to tip over or bounce a lot Happy excavations to you, these are fun to run...

I only wish that i had your time and patience, congrats on the find!!

Very cool best of luck thanks for the video!

Always worth running drop of oil around the seal on a new filter, and don't use the filter wrench to tighten the filter - you can see where you damaged the new oil filter in the video!

Here's a tip for oil filter change with less of a mess. Once you get it turning put a plastic bag over the filter then unscrew the rest of the way with your hands and work area protected from any spills.

Never call the boom a “dipper”. Lol

Nice insight! I'll probably never need one but it's nice to know there are working models for the price point.

Congrats on the machine! Liebherr makes great equipment. Just note that those should be ran at high throttle to get the fan to move enough air to keep it cool. 👍

Nice work, good machine. You’re gonna want to make sure the top of the bolder is at least four feet below the surface below the frost line. We have a saying in CT, rocks grow best. The water gets below them and freezes, then pushes them back to the surface. I cut over 100 trees in my yard, about 36 of them were between 100-125 feet tall. Stumped it all out to make a field, and all the boulders I left in the soft soil I disturbed have poked up to the top. Also learn Fromm your mistake and try to keep your top soil and fill in separate piles when you dig the holes so when you fill them back in the top soil remains for grass to grow

Is there a Part 2 to this video? Looking forward to it :)

I dare say its first time that old excavator has ever heard someone exclaim "oh my goodness" when something went wrong.

South western PA equipment tech here. Those are the best damn engines you could ever ask for. They are almost bullet proof. Soooo easy to work on. The only thing to watch for is the timing belt. They are interference engines. If the belt breaks or slips it will bend every push tube in it. However, still super easy to change because it’s oil cooled! No mess taking the head off. P.S. that Stauffer diesel that rebuilt it is the authority on these engines on the east coast. If they don’t have the part, it doesn’t exist. Good luck man. Enjoy

Those Deutz air cooled units are great engines, easy to work on, But replacement parts are vary expensive so take good care of it. I worked for Atlas Copco Wagner Mining Equipment Co as a diesel mechanic for 18 years and we put a lot of Deutz engines in our machines. Those batteries you used should more then ample in that machine, no need to upgrade to the larger battery if everything works fine. Also the next time you change your oil you can install a remote oil drain on the engine, simple to do, we did it all the time on our machines for that simple fact. Also you can steam clean or low pressure power wash the inside of the engine to keep clean the oil coolers that’s important. The oil is the life blood of the machine. While I’m talking about oil have you heard of IXL Oil Conditioner products???, I’ve been using this brand for over 30 years in my personal gasoline car engines, axles, transmissions. You’ll have to go online to the IXL store or maybe a diesel truck shop. They have a great line of products. You might want to install a oil temperature gauge and maybe a pyrometer gauge in the future. Also if and when servicing the hydraulic filter and system when refilling and I’m not sure of the hydraulic system design but pre-fill the hydraulic filter so you don’t run the hydraulic pumps in a dry state on restart after service. Then when the machine is not in use have the boom n bucket in a down position that all the hydraulic cylinder rams are retracted into the hydraulic cylinders to protect them from external damage, you don’t want to have to replace one, Probably over 1,000.00 dollars. The big thing to remember is if you break something on that machine you could be easily over the original price you paid for the machine, just don’t do anything stupid. Happy digging👍👍

Nice vid! Part 2? Bueller?

Part two where you dig the mountain up please? Haha

$7500 for a running machine, no matter the size, is amazing. I'd have expected bad engine, failing hydraulic pump, cracked boom, and a half dozen other issues for that price.

I worked at this type of equipment for my fathers farm and wold make one comment when dealing with older stuff like this. We bought a steam/ hot water power washer and it changed my life. The accumulated oily grime that infests every inch of machines like this can be cleaned off with relative ease making working at them a much more pleasant experience, it also reduces the risk of grit and grime getting into important parts during maintenance and helps stop you getting a thick coating of greasy grit on arms and face. Nice machine looks like it will respond well to a little care. One other point check all the major hoses and replace any sketchy ones before they let go on site, it can save aeges of wasted site time.

I use to work at liberty international in Manchester, those valves on the oil pan are called no spill, you can get an an adapter and a hose that will plug right into that fitting, presto no mess. I use to sell those things.

Love the video and instruction. Marvin❤

I like Hans as a name! And if you ever get a small excavator of dozer, you can name it Franz. As for the way it operates, it sounds like it's really laboring when you use more than one function at a time. That is usually from clogged fuel filters, so hopefully when you get the primary filter replaced, Hans will operate smoother.

Hey Waldo, I like your show and admire your skills and guts to tackle big jobs. One tip, tie shop rags around your wrist's to stop liquid from going to your armpits during overhead service. LOL. I really like the projects you share. Keep up the great work.

"Some of the glass is missing" *pans to a cab with one pane of glass behind the driver*

You should keep the boulders for landscaping instead of burying them. Always enjoy your videos. Hopefully we get a part 2 follow up.

I use to be from NH built in MASS, Excavating contractors use to give estimates off of the site plan for septic, material needed, stumping, cella hole and back fill, utility lines, driveway, basement prep et-cetera. The only additional would be the unknown boulders over a certain size and if ledge needed to be blasted out. Then someone somewhere somehow started the idea of " Hourly rate per machine plus trucking." Tried another contractor and realized it was the "New norm". I once showed up on a job to meet the operator, 7 am as we drank our coffee (pre-cell phone days) we went over what needed to be done. I left after about 1/2 hr (hr meter running while machine warmed up) and an hr and a half later forgot to mention something so I drove back he was still in the same place talking with another contractor that was working next door still drinking coffee. That was it for me besides. They also charged per yard for material and for kicks I calculated a dropped load and low and behold short of what I ordered. You never got what they charged. I once mentioned, pissed off to one site contractor that I was going to buy my own machines. His reply HA I would not. Do you know how much the parts cost? So I did what you did I found an old Hitachi ex-120 Had no clue how to operate it and figured I made a mistake but I stayed with it and in 40 hrs I was efficient and confident enough to have at it. Your machine can pay for itself in a week. Great job great vid.

Tip on that oil drain plug: Install a short hydraulic hose with a valve or a hydraulic coupling at the end. This will provide better control when draining, and the latter option gives you very low spillage and also provides a way of draining into a sealable container.

I would definitely use some kind of engine flush or atleast a bittle of mystery oil to clean up everything inside the motor thats sludged up. Mystery oil helps so much when it comes to cleaning sludge and stuck lifters.

Thank you for showing

You got one heck of a deal there Waldo, Beast mode love it. Otto is going to look great with a new paint job.

Your enthusiastic appreciation for this machine and what it can do is so refreshing, especially when compared with some certain other popular KZfaq channels. I hope you do a lot of great things with it.

The hydraulics upkeep is insane.

Beastly Otto, when yo Beastly Otto at it Again !!!

Waldo, please install some plexiglass or wire meshing between you and the material you're handling. That thing has a lot of power and if some of the stone breaks off, the chips could hurt you. At least use some glasses. A friend of mine has lost an eye using digging equipment. A small metalic chip broke of somewhere and screwed up his left eye for good while working with the windshield open and no eye protection. Don't take it the wrong way, just a heads up, can happen to the best! Good buy, have fun with it and be safe

What about part 2? When will that be released? Really curious how it performs after some time... and the lab results of course!

Where’s part 2?

Great video. As a general rule, always dig over your track idlers. It is the best for the track frame and final drives.

Man, I thoroughly LOVED this video you made! You were humble enough to show your oil change goof and to admit you were an inexperienced operator. But you showed all the common sense steps from initial transport prep to actual transportation which was really interesting. Although I am curious how much these oversize and overweight permits ran you plus delivery costs per mile. I think one other problem you'll run into sooner than later will be finding industrial replacement parts for this 1986 LIebherr 926 excavator. I sure hope you post more videos of GUNTHER. Yes, in Deutsche, “hard, strong man" is befitting this 40-ton beast.

Who do you use for your oil analysis? and what are you looking for on first one. I drive semi. I see getting analysis over many. I started doing on my truck when I bought it. I use Blackstone.

lubrication professional Dohhh !!

Been running excavators for 20 years and you did very well for your first time .. you'll be a good operator because you're pitcular and pay attention to fine detail 👌 keep it up!

Been away from the excavating for many years, but after 30 yrs owning I suggest 1) grease every fitting regularly and replace/repair any that don't accept grease (sometimes just raising to remove weight from pin hydraulically will allow fitting to accept grease 🤞, other times untreated impacted grease/dirt requires pin removal) one reason it's inexpensive, but you did a good buy it seems. Many experienced responders on here. 2) I don't think new teeth are a priority (won't help) for your application as long as they aren't worn through to the shank inside tooth. Your smaller backhoe loader will level up and grade for you once you get the touch.

That button you thought was a starter button is probably got your glowplugs

DRACULA...😂

Definitely check out your hydraulic system, check level and strainer/filters Tighten the tracks, not overly tight but those are pretty loose. And the exhaust dumping in the engine compartment will cover everything in soot, any work you do and you’ll look like you just clocked out of a coal mine. You seem competent enough to just make repairs there so that will save you on parts. At the end of the day it’s just a machine if you keep up maintenance on one they tend to keep lasting, try not and side load your boom where you can help it, excavators are the most powerful in a dig to you motion around a 90° boom angle but as an operator myself you’re not bad at it, Smooth is fast, even it it doesn’t seem like it. Reduces wear and operator fatigue over bouncing around. Just remember the farther you are out the less control and power you have. Grease it regularly and keep the fuel tank full to lessen tank rust and moisture buildup in the fuel and the experience will come with hours put in. It’s always fun to see what Waldo is working on. ✌️

Tip: you crushed the filter while tightening it with those pliers. In fact oil pressure is not as high as you may think(cat c15 manual says dependent on rpm between 40-80 psi). This means if you have properly cleaned and lubed the surface of the filter and the filter housing, hand tight is usually enough (depending on grip strength). If not a filter socket or the metal band style filter wrench are best. Pliers are for taking off not putting on.

Man for never being on a excavator you really did amazing

Two Tips: 1) get an electric grease gun if you don't have one already. I know Milwaukee has two different ones. I assume most other companies like DeWalt and Riobi probably have them too. 2) You should look into selling the rocks. Where you live everyone has them in their yards, but in other places that is not the case. I live in South Jersey and it's flat and rockless, so if we want rocks of any size we have to buy them. Just something to think about.

Rebuilt in the town I used to live in, Ephrata pa!

I love this video! Thank you for sharing. It’s good to see old equipment have second life. A lot of machinery out there that is begging for another shot but unfortunately gets scrapped…. Btw, for someone who has never used a large excavator before, that wasn’t too shabby at all!

Super clean in a sprayer and a pressure washer...did this on a 1953 ford NAA tractor before painting. Works good.

You got an insane deal on that. It needs almost nothing and isnt all slopped up. Crazy deal.

Love the channel and these videos!

I do not work with or have a hobby that is related to machinery like such, but I truly enjoy this video. Thank you, and good luck with your future project!

We are waiting for part 2

Vinhelm that name fits well, also great video this was a ton of fun to watch!!

I really enjoyed watching as you stumbled through the learning process which allowed me to learn a few things also. I have never operated machines like this, but I enjoy seeing someone else do it and your video is very informative and complete. Thanks. (I'm happy I found Waldo)

the only issue i see with burring the rock is the frost pushing them back up.

Hell of a buy for the money!! I was looking at old backhoes that cost more than that. Need one of those on my farm! Gunther or Fraulien is catchy😮

Now we know where's Waldo: Excavating the backyard

I honestly love your videos Waldo, so chill, good camera angles and a good attitude to new things!

I have watched this video twice now and I have really enjoyed it! I have a lot of experience with those machines. Approximately 35 years, give or take, operating and fixing them, or transporting them... of many sizes. Very nice video Waldo

I live in NH too and removing rocks is always a pain

Just found your channel and have been binge watching your videos. Love the content. Your excavator engine was rebuilt near where I live.

This is quickly becoming one of my favorite channels. Well done

Oil filter installation tips, wipe the o-ring with fresh oil and install by hand, only use your hand to tighten the filter. Never use a wrench to tighten oil filters. You can bind the o-ring and ruin it causing leaks. Also if you get lucky and don't ruin the o-reig they will be over tight and much harder to get off the next time.

Call it Rasenmäher 😂

Fellow New Hampshire resident too!

Nice machine! Lots of iron for the price. When you’re digging something like that out, try to do it with the idlers facing the rock. It’ll be a lot more stable and you’ll be able to put more power into what you’re doing!
