Deutz industrialmotor cylinders

Jappe914 · 11:53 AM

Have any of you ever heard or done this? Deutz makes aircooled industrial motors f.e.x like this .
Cylinders can be modified to go into T-4 engine. I have one set machined (see pics) Cylinder walls are thicker than any stock T-4 cylinder has, so it is good choise to use those with larger displacement engines. I have 101,6mm pistons.
I will tell more about modifying if someone is interested

Verry cool! Thats the kind of inovation I like to see. Is there any price benefit? I'm interested in more info.

I paid for those new TRW turbo pistons with new totalseal pistonrings, and already machined cylinders only 500 euros. (very cheap, normally 4 pistons would cost that much here) I don't know are those deutz engines common in USA, but a good condition set of those costs about 100-200 euros + machining.
I'm looking for original deutz cylinders so I can take some measurements and tell more for you guys...

I have seen this done, and its not very hard. The cylinders don't cool super well because of the short, fat fins....

Jappe914 · 03-09-2004, 07:36 AM

yep, those fins are quite short compared to stock T-4 fins. But I don't think that heat will be a problem, if everything is made right.
Next move is to add oilnozzles towards bottom of piston. That will help a little. How usual are 911 fans over T-4 block in USA? That blows more than stock fan.

Jake Raby · 03-09-2004, 07:50 AM

The 911 fan IS NOT the answer, neither is more airflow! I learned that and have the data to prove it. The key is correctly routing the air to the most im,portant parts of the engine.

The USA is filled with guys that want huge airflow, and looks and are willing to take less for cooling and lose 20HP to fan drag... We aren't too smart over here when it comes to practicality.

Jappe914 · 03-09-2004, 09:05 AM

I choose 911 fan cause it's easier to add to my engine than stock system. You can allways make fan to blow as much as you like with different diameter pulleys...

Jake Raby · 03-09-2004, 09:46 AM

I used from a 1:1 drive clear to a 1.6;1 drive and it didn't help cooling- proven.

All the higher drives did was suck more power off the engine.

Here in the midwest, tractor junkyard diving is an art all its own! Bring your 3/4 drive socket set.....

Deutz's sold a lot of tractors here in the 70's and 80's so they may be fairly easy to find in the junk pile. Dealers seem to have thinned out, so the junkyards may have kept them instead of scraping them right away. Also, some Ditch Witch's had Deutz motors I believe. (DW's are a common small trencher here in the states, Jappe914.)

Do you have a engine size/model that these cylinders came out of?

I have a set of Porsche 3.6 P/C's on reserve to put in one my Type IV blocks laying around. I'm watching what the guys on ShopTalkForums do with theirs before I start cutting on them.

Experimenting with a set of Deutz cylinders from a junkyard sounds like a sporting weekend to me!

I'll drink Aquavit instead of Budweiser that weekend,

P.S. is there a website where I can get a FIN country code bumpersticker for my 914? Thanks.

Ooops, never mind about the model number that is posted on the website...... And I can't blame the Budweiser today.

I was an applications engineer for Hatz Diesel in the late 80s; Hatz is Deutz's chief competitor under 80hp, and they also have some super quiet air-cooled engines. www.hatzusa.com or www.hatz.com Both Hatz and Deutz cost an arm and a leg but run forever, usually in construction equipment, stationary power, etc. Some of their older engines were super long stroke, IIRC 108mm bore x 120mm stroke. Anyhow, lots of torque. You'd probably be shocked by the price of new parts... cylinders are probably a couple hundred dollars apiece at least. Hatz used to use the Paris-Rhone alternator that the 911 also did, and the alternators were something like $1100 each. Works no better than a $150 Delco-Remy unit, except that it fits inside the blower housing.

I couldn't resist searching around on this subject.

Two Deutz engines have cylinders that would work. Models 912 and 913. 912 has 100mm cylinder and 913 is 102mm by what I could tell. The engines are set up like Detroit Diesels, i.e. same cylinder design, more cylinders for more power (471,671, etc). I haven't found which tractors these were used in. The one junkyard I called couldn't use the engine model number.

I found one vendor of new cylinders/liners online based out of Farmington, NY. $76.80 per cylinder.

I'm interested to know if they would eventually have the same problems as the (iron) aftermarket big bore cylinders that are made for Type IV engines.

Jappe914, do you have specs that a machinist could use to fit these to our engines?

yes, these are inline unit type engines, just add one more cylinder to get a larger one. The models you refer to are known as FxL912 or FxL913 engines, where the x is the number of cylinders from 3 to 6. However, the stroke on those is 120 for the 912 series and 125 for the 913; how do they get cut down?

good site for specs: http://www.deutz.com.au/Specifics.php

Price for Deutz is better than I remember for Hatz... maybe why we had a hard time competing!
