Everything You Need to Know About a Deutz Air-Cooled Diesel

[@Maus46]

Absolutely bulletproof engines. When I was in the army, all the old generators had those engines. Their super loud but ran forever.

[@KrisDouglas]

And they sound godlike when they rev up.

[@Danger_mouse]

Definitely far from bullet proof, broken head studs and the resultant blown blast ring on the cylinder head kept our local repairer in money 💵 Glad they do not use them any more in the mining machinery we run.

[@dieselgeezer18]

@@Danger_mouse hahahh nice joke. I got a 50 year old Deutz tractor and the engine still purrs like a kitten. Its been abused really bad and its still working.

[@Danger_mouse]

@Frauenarzt Dr. Stefan Frank The ones we had were in underground mining. It was a case of the wrong application, hot environment not suitable for air cooling and very salty underground water corroding the head studs off and frequently blowing blast rings I'm sure in a nice cold country, on the surface and cleaned well, they'd last a lot longer. They are very very basic, so not much to go wrong.

[@mathewmerkl576]

With the deutz numbers B- means its turbocharged F- means its in a mobile vehicle 6- number of cylinders L- means its aircooled (luftgekult) 9- series of engine 13- the stroke of engine in millimeters (130mm) :)

[@Apexistant]

isnt the stroke in centimeters then?

[@mathewmerkl576]

Yea i guess those numbers would mean centimeters but the stroke is measured in millimeters

[@k.m.h.1346]

Luftgekühlt!

[@larsloschwitz9448]

A instead of F means, it's a multifuel motor. They are built with a little bigger gap between the piston and the cylinder liner, so they can operate at higher work temperatures. Only downside is an increased fuel consuption. They can run with vegetable oil, or even mixtures of alcohol and oil, as long as the viscosity of the mixture is close to that of regular diesel fuel. I just love those aircooled Deutz motors. They are there for you, whenever you need them. No Electronics, so they would even still be usable after an EMP-Strike. The supply of spare parts is nearly infinite and all the part lists and repair manuals are publicly available, so you can fix everything by yourself, provided you have a minimum skill in the use of the required tools.

[@invertedv12powerhouse77]

Yep, that's true. . . and yet many other manufacturers don't want give credit where credit is due! Back in the 80's Deere wanted to buy Deutz, guess what ? They discovered Deutz was Big Brother so to speak. KHD was building engines that Deere wasn't into and KHD "Deutz" was a lot bigger engine company than Deere, lol, lol. . .

[@cudwieser3952]

Another reason for the legendary status of a Deutz engine is because the company was founded by Nikolaus Otto, originator of the 4 stroke engine. The engines are the originators and a century of work really stands for something.

Far from bomb proof, constant overheating issues, broken head studs all the time and it seems as if all old air cooled diesels are allergic to any type of real hard work.

[@farmerbarnaby3844]

Stop bullcraping. These air cooled Deutz engines are superior. I've got a Deutz d30s with the F2L812, had it since 2008, nothing has gone wrong with it. The hour meter wasn't working when I bought it, and it still doesn't to this day, yet it displays over 5000 hours. Could be over 15000 hours as the hour meter only has 5 digits. You can leave it sit for over 3 years and it'll start right up (talking by experience). A local farmer also has an older Deutz with the F4L913, he leaves it in a field opposite my house during the summer so he doesn't have to drive 2 hours to cut the hay (his farm is about 17 kms away). I decided to peak at the hour meter in the cab; 9800 hours. Once again could be 19800 hours, as the hour meter is only 5 digits. All this to say that Deutz air cooled engines are awsome. You would have to seriously abuse them to overheat, or break anything on them. An engine is as good as you make it.

There are stories, possibly true of loosing a cylinder to enemy fire. The mechanics apparently removed the con rod. Covered the crank case hole with gasket material. Drove the loaded vehicles in one case 100km home. Plenty of vibration. The motors revved out at something ridiculous possibly 3200 rpm but huge torque. As good and in some cases better than our small Mogs (MB Unimog)..

[@gregculverwell]

Love Deutz aircooled engines. Very tough. Decades ago I was driving a truck with a FL914 (12l 232hp v8) when I had a runaway down a long steep hill. The tacho went around the dial and Back to 600 on the other side. The only damage was that the rockers smashed through the covers, so the engine was covered in oil (easily fixed with some braizing). One thing I thought was very cool was that it used a centrifugal separator built into the fan hub instead of an oil filter. Seemed to work very well - would take out a 5mm layer of black rubbery material at each service.

[@Hakkeholt]

Must be Magirus or Iveco, guess that'd be and f8l513 or something like that (there's no 914), these v8 and v10 v12 are quite impressive engines.

[@gregculverwell]

@@Hakkeholt there is a 914 engine (inline not vee) I confused it with a tractor in my life. It was actually a f8l413. The trucks full of name was Magirus Deutz 232 6x6. Later the name changed to Iveco.

[@larrygingerich2585]

There is an option for using engine oil for cabin heating, which utilized a valve attached to the exhaust manifold, heat caused the valve to open, allowing oil to flow to the fluid / oil clutch on the cooling fan. This enabled heat to be optained for the cab of a tractor or a truck. This is not a centrifugal filter for oil, but it is a centrifugal / fluid drive for the cooling fan.

[@larrygingerich2585]

The 208, 210, 211, 413, 510, 512, 610, 611, 812, 912, 913, 924 series are "air cooled engines" and I believe there are a couple more. Then there are Deutz "oil cooled" engine series such as the 2010, 2011, 2012, and more that are set up with or without an oil radiator etc. Also on the 413,812,912,93,914 engines, inside the cooling plenum of the engine is an oil cooler for the engine oil. 2 cyl and 3cyl engines have a tube with fins whereas the 4cyl, 5cyl, 6cyl and v-engines have block type oil coolers in the cooling plenum.

[@zulugordon8680]

In the late 70s there were V8 & V10 engines with the 914 engine. The V8 was rated At 230 HP. Great engine & had lowdown torque. Most of them had oil pressure driven fans that also acted as a oil centrifuge to collect the carbon soot from the oil. I think they also had a normal oil filter as well. Did my apprenticeship on them , Leyland & Landrover.

[@slicktires2011]

@@montybolinger6383 You're right. The fact that there is an oil cooler does not mean it's "oil cooled". All engines, including water cooled engines, will remove some heat through the oil.

Top tip for setting the piston to cylinder head "bump" clearances is to fit more shims than you need, if your solder clearance is too thick you can just lift up the liner and cut shims off one by one as needed to get the correct clearance. Saves lifting the whole liner off over and ovwr again.

In airport circles, 912 series made a name for itself in the Vestergard de-ice trucks. I was a mechanic for Delta & personally I loved those engines. Always started in about half a turn rotation no matter what or how cold it was. We changed oil & threw an air filter & a belt on them once a season, I can't recall ever adjusting valves or anything else. The very definition of reliability. It was nothing to see them roll the hourmeter over 5 or 6 times. Equipment would be worn out, rusted & sold off long before the engine was done. The 1011 & 1012 series that followed were maybe not ultimately as reliable but they have several things going for them also. I know many make fun of the 1011 for having a timing belt but honestly it's super simple to change, doesn't destroy the engine if it pops (need new pushrods, nothing else) & I've seen beltloaders go over 5000 hrs without having the belt touched. It has the advantage of basically being impossible to overheat due to the oil cooling. 1012 6cyls have a distinctive bark all their own, much like Perkins has its own sound. I'd recognize them a mile away, torquey sob's. Never any trouble as long as the ramp rats kept oil in them. We also had 2015 V8s in the air start carts & some of the Goldhofer jet tugs. Physically a huge engine but thunders away like a Scania at full tilt. Power of God, always wanted to see how one would drive in a highway truck. Also got a cool inline P-pump that would be awesome sitting in the valley of a 7.3. I miss those days. Now with the dpf junk, probably isn't any fun to work on any of it.

When my brother and I were in service school in the 80's, a dealer told the story of how a farmer dismantled the engine on his New tractor to see how it was made. He put it back together and the cylinders seized up! Why? He put the wrist pins back together by tapping them into the pistons. Without heating the pistons, the wrist pins tightened up, and in turn scoured the cylinders. . . lol.

I bought a 30k stump grinder with a 3 cyl air cooled deutz diesel for $50 . they were about to scrap it at the scrapyard , it wouldnt start cuz a wire for the fuel shutoff solonoid and they couldnt start it ... But i could ! And it is a awesome little engine !

[@punkinhed81]

My tractor has a 4 cyl 914 series. its a 2006 agroplus 80 some of last air cooled. 07 or 08 they went to liquid cooled to deal with emmisions. Runs cool and super easy on fuel!!

[@KEIFabrication]

Nice, well engineered engine access and maintenance. Thanks for the education! I think I might be a Deutz fan know!

[@colbypurkeypile9274]

Got the same 6 cylinder on a water pump. Cold blooded but man it’s reliable! And easy to work on. The one thing made in Germany not over designed.

[@Danger_mouse]

The VW of the diesel world. Multi cylinder antique tech and allergic to hard work and heat. Glad we don't see them much any more. 👍

[@1978garfield]

I am surprised to find so many in the comments that love them. I don't know if it was maintenance issues or what but the few farmers I knew that had them had nothing but trouble. It seems like if they were so great they would have sold well. They did not. Agco bought the business for much less than Deutz paid for it.

F6L913 F - fast revving 4 stroke 6 - 6 cylinder L - Luftgekuhlt (air-cooled) 9 - engine family 13 - stroke (12 - 120mm, 13 - 130mm)

[@MrSuwds]

Motor Tatra T913

[@cesargallo7424]

F6L913 => "F" alone for non turbo, "6" is the amount of cylinders, 913 is the series. Those who have turbos have the "B" at the begining: BF6L913, and those with intercooler have a "C" at the end: BF6L913C. Awesome engines, super reliable, and you can beat the hell out of them without worring.

[@cesargallo7424]

Also the engines are modular and each cylinders has 1 liter and go from 3 to 6 cylinders. 4 cylinders (F4L913 and BF4L913) were used for vehicular application and is common to see them here in Argentina in pick up trucks like Ford F-100 for diesel swap. 6 cylinders turbo engine BF6L913 was also used in Dodge 1000 truck as stock engine. You can see lot of them in generators and pumps. Many tractors of different brands used these engines and they still keep runing healthy. So, as you all can see, they have a wide range of application and are very famous in my country. :)

The 9 is the model of engine and the 13 is rougly the stroke in cm ive been told

looks like it needs a PTO brake. the PTO is turning when you backed It out the shed.

[@ryaneckert8079]

They don't have a pto brake at all, they all freewheel when idling. But you can grab the shaft and stop it with your hand if in neutral. Great to hook up with engine running, you dont have to turn the implement shaft to get hook up the pto.

Funny story... My father was a cutting tool engineer for TRW and later RTW. I used to ride along with him on his calls. I remember pulling up to the Deutz plant in independence Kansas. I remember saying as a jerk 8 year old... "dad, this is just farm equipment... when can we see something cool?" His response... "Son, these people build one hell of an engine and while it might not seem cool, running for a long time is pretty cool."

[@damienmccormack2789]

Brilliant engines, still probably the most reliable diesel I've ever come across. All the issues that I've ever come across have come down to lack of maintenance or straight up abuse. Only complaint is the 2 cyl ones are the loudest violent things ever but just run for ever. I've had them on everything from ditch witch machines and Vermeer trenches to tractors. Certainly the air cooled are far away ahead in reliability than the new electronic water cooled ones these days. Basically most of the equipment only got an annual service regardless of hours and the old stuff is still going where the new stuff is in some cases being worked on weekly just doing service items.

You can still buy aircooled engines from Deutz new, but as you mentioned they only reach tier 3 emission standards.

[@skinanbonesOG]

great video, I was at a customers home putting in a pellet stove. We got talking tractors and he took me out to his drive shed that had a restored late 40's early 50's Deutz single cylinder tractor. As far as he knows and was told, this tractor was one of the first to be imported into canada

[@MisterRudolf]

Could be a a F1M414 If its watercooled or a F1L514 if its aircooled. Until the 60's, Deutz tractors had the same designation like the engines. Cool stuff. Didnt know they we're exported to the US :)

I ground my teeth on an old Magirus dump truck with a V10 Deutz. The blower was oil controlled, and when it got warm it did its best impression of a jet engine sound. Plus, it acted as a centrifugal oil cleaner, pretty well thought out. It was a nice soundtrack, the Deutz with the Fuller-Eaton non synchro gearbox, it would play all sorts of tunes when you didn't rev match just right!

[@Erd_Geschoss]

Interesting, when I was working an these engines, the cylinder kits came with four drifferent spacers; You would torque it with all four, measure squish and then just lift the assembly slightly and clip the exess ones off.

that tractor would aggrivate me to no end after owning a john deere 4455 mfwd. Better fix that rain cap so water doesnt seep down into a cylinder and hydrolock it. All those air cooled tractors have to be sold out of europe for new low emmissions machines right or wrong lots are ending up back in the states. Ya no dirt and dust around when plowing and seeding smh useless design

[@MrWomojo]

Fun fact: Unlike the original Deutz factory itself ("Deutz" is the name of a district in Cologne) the Magirus factory (Magirus was Deutz's Truck subsidiary) was located in the south German Town named Ulm. These two towns have two of the most impressive cathedral buildings you could find in Germany. And you can guess the Cologne people are very proud of their cathedral (two towers) and identify alot with it. The Magirus brand logo was the "Ulm Minster" (Cathedral) silhouette (one single, but even bigger tower -highest in the world so far). And that's how to this day the logo of one of the most ingrained Cologne companies actually shows the cathedral tower of the Ulm Minster combined with the "M" for Magirus.
