Deutz 4x4(1985 GMC)
 

Got the motor off eBay. Its an F5l912 deutz.It has a Chevy bell housing adapter. My 6.2 gave up in my 2wd, so i got a 4x4 frame and am going to swap the body over. Going to use a 700r4 to a np241 and 3.08 gears for a cruise speed around 1500rpm.

Here is where I'm at other than I fabbed some engine mounts.

Re: Deutz 4x4(1985 GMC)
 

Tell me a little about the motor - not familiar with it. Cool project for sure.

Re: Deutz 4x4(1985 GMC)
 

Its a German made air cool diesel. Its 288 cubic inches. 4.72 inch storke and a 3.9370 bore. It make 100 hp at 2800 rpm and about 308 ftlbs at 1450rpm. Not bad for a NA diesel. 5 individual jugs and 5 individual jugs that can be replaced independant of the other cylinders and can all be done without removing the oil pan. In other words if you score one cylinder you can buy one new jug and piston with the misc. parts and repair it in the vechicle.

Back in the 80's deutz used these 5 cylinders as an $8000 dollar swap for American trucks and vans. Motors came with a 300,000 mile warranty.

According to stories from my grandpa a guy had one in a chevy van and got 30 mpg pulling or not.

Parts a pretty cheap if you know where to find them. (ie injectors were $36.00 a piece, valve cover $7.90 a piece.

Deutz also made 2,3,4,6 versions as well. They all used the same jugs and heads.

Wow, that's a very interesting motor.

Re: Deutz 4x4(1985 GMC)
 

Dude, thats badarse! I've always loved Duetz and have always tossed the idea of one in a C/K, thats sweet you did it! You gotta get some videos up when its done!

Re: Deutz 4x4(1985 GMC)
 

The Duetz F diesel is a damn fine example of German engineering. Simple, reliable, and economical modular design. In for the build.

On a side note, looks like you have plenty of room for a little turbo;)

Re: Deutz 4x4(1985 GMC)
 

Once I get i running and driving a turbo is going on.

If anyone wants any specific pic I'll do my best to get them.

My next step is to add some leaf springs in the front to help the 13 quart oil pan clear the front differential. Its about 3/4 of any inch front sitting on top of the pumpkin.

Thanks for the perks.

Re: Deutz 4x4(1985 GMC)
 

Air cooled? How reliable is that in a warm climate?

Re: Deutz 4x4(1985 GMC)
 

Sweet looks like its gonna be a fun ride for sure. Keep up the good work!

here is a website of the 79 3/4 ton with more pics

Make sure you check out the two videos

As for air cooled having hot issues we have 6 cylinder in a deutz 100 06 tractor that won't overheat pulling a plow busting sod or grinding feed in the middle of a 90+ degree day in the summer.

If you think about it, all the water does in a liquid cooled motor is transfer heat from the cylinders to the air. A deutz just removes the water from the equation.

Great link. Thanks!

Re: Deutz 4x4(1985 GMC)
 

way to go, that is very cool power plant, don't know much about that engine but it sure is cool.

Re: Deutz 4x4(1985 GMC)
 

x2

I drove a 65hp deutz 4cyl pulling a shredder that was too big for it and It outpulled and stayed cooler and used much less fuel than the other tractor (an older 90hp 6cyl Oliver) we used in a 100+ degree Texas summer.............one note though, when operating in dusty conditions you have to blow out the dust from around the cylinder jugs every now and then or cooling efficiency will be greatly reduced

Re: Deutz 4x4(1985 GMC)
 

COOL never heard or new of these. Great alternative to a 6.2 or a 6bt

Re: Deutz 4x4(1985 GMC)
 

Cool build. I have often thought about putting a Deutz into a truck. I think these engines are great. I work as a mechanic for a railway that is in a very remote area and all of the gen sets use Deutz engines. They have 2,3,5 and 6 cylinder engines that run 24 hours a day 7 days a week and they run for years! I cant even imagine how many hours some of those engines have on them. I can't wait to find out how it works for you.

Re: Deutz 4x4(1985 GMC)
 

So how are you going to heat your truck? A/C would not be much of a problem with the proper size clutch pulley. Low rpm engines usually need small clutch pulleys to keep the compressor up to speed.

Ford was working on an electric heater to run before the coolant was hot. Maybe that would work. Or JC Whitney should have an electric heater of some sort.

I like diesels. I have a 6.9IDI International. It is OK, but I want a 7.3IDI, the bigger brother. I'll be watching and waiting.

Re: Deutz 4x4(1985 GMC)
 

Do you have a vacuum pump for the brake booster?

Re: Deutz 4x4(1985 GMC)
 

for heat i plan on using a oil cooler inplace of the heater core. For ac i think it will work fine because the crank pulley on the deutz is about twice the size of a regular chevy. It should spin the other pulleys faster.
For cold starting I'm going to use a cummins grid heater. I'll post new pics as soon as I change the hard drive in my other computer.

Subscribing so I can learn more....

Re: Deutz 4x4(1985 GMC)
 

for brakes I'll beusing the trucks hydraboost since a 6.2 diesel was in there before. The motor came with a vaccum pump on it that is lubed by the engine oil. I use that for the cab acessories.

Re: Deutz 4x4(1985 GMC)
 

Great. This should be very interesting. Low end torque. That is where it is at for a work truck!
