I had always wondered why Deutz never had water cooled exhaust manifolds. I grew weary of watching them, and the turbos, glow in the dark. 1,800°F will do that. Really cokes up the oil. The 620's that we were running were replaced with lightweight Cat 3512's. Very sweet!

Deutz the worlds oldest engine company and still going strong.
Excellent engines on the whole.
There is nothing wrong with the now old air cooled 912/913, the problems you run into with them has generaly been the last person to work on them or installation design probs.
A verage Life span of these engines when maintained properly 10,000-15,000hrs some i've seen past 33,000hrs depending on application.

I have a Deutz D908 and it's a problem with an engine inside.
The DEUTZ engines are the worst in the world. Mechanical Problems, Engenheering problems, the company works very badly in the costumer services, they don't answer emails and they are waiting to end of the guarantee to be able to get by with the problem.
Do not buy DEUTZ engines run from problems and avoid paying for expensive engines.
If you need a Generator buy a low cost one... you will see it's better.
Nice video. This engine is also running in the MS Koegelwieck, a dutch high speed ferry. Originally she was fitted with two 604's, they have been replaced back in 1995 for the two 620's she's has right now.
I've had a little experience with air-cooled 6-cyl Deutz engines in trucks. Most of it not too good. I call them the 'Corvair' or 'Volkswagen' of diesel engines. They were very light weight but the light weight didn't make up for the increased maintence. Also, the cab heaters were terrible in the winter time. They used an oil radiator in the cab.
VW engines are not Deutz engines... My God.. Deutz were very good engines. Lower maintenance costs and you can put them in anywhere. America can never come up with anything that comes even close to german technology ;)
Old american engines were back then already outdated. These air cooled engines have low fuel consumption. Something you still can't say about newer american engines. You saw these engines a lot in cranes, loaders etc. Because of their economically, power and simplicity. They are easily to revise and the costs are lower then with water cooled engines. Nowadays they have to stop with Air cooled because of the TIER norms. some of Those engines consume 180g/kWh. Best watercooled engines 192g/kWh
My only experience with them was in trucks; both the in-line 6, and the V-12 versions. The experience was not good! The maintainance and repair costs far outweighed any possible advantages they might have had in fuel economy and light weight. Lots of oil leaks, noisy, relatively short life to overhaul, and very difficult to heat the cab of the truck in winter. AND, emissions is part of the everyday world these days for ALL engines.
What kind of trucks? The engines of Deutz here get between 9000-14000 hours without overhauling in cranes, loaders etc. Oil leaks also not a problem, unless it's almost time to overhaul them, then they start to 'sweat'. Noisy is also a question of a good isolation of the truck or not.. Indeed all engines have to withstand the emissionstandards. But still now you see there are engines that can do a lot more with less then others.
I will definitely agree that a truck is the absolute most difficult application for a diesel engine. A truck engine can be lugged, shocked, (by hitting docks when reversing) and driven to overspeed coming down hills. All of these conditions are not present in a boat or a generator. There ARE engines that survive truck applications much better than Deutz. Most current American truck engines have basic WARRANTIES that extend to 1,000,000 miles which equates to 20,000 hours @ 50 MPH.
MAN and Mercedes-Benz trucks get those kind of miles easily for years. And not only the engine ;) And a truck is not the absolute most difficult application for that. Tractorengines and transmissions for that matter are even more used in all kind of possible ways and positions.. For that matter the Deutz engines are superb. No better engine for working every day under a great sideangle than a Deutz.
@JGMagoo air cooled 6cyl deutz is really great piece of engine. I work on cold milling machine from Wirtgen with this engine, well over 18000 work hours, no overhauls so far, oil consumption is close to nothing, no need to add any on 500hours maintainance interval.
have heard of the big problems with this type of Deutz! (i have a mar 428 6 cil Deutz 50 year oldin my tug , absolutly no problems! at 500 rpm max! (250 hp)better take that old engine back in production!(LOL)
I work with a pair of 604s right now in addition to the 620's. The 604s are a maintenance nightmare - daily oil additions, exhaust leaks, heat exchange issues etc. actually looking to repower next season. There are rumblings that Wartsila will be making a new series of 620s.
What are you looking at using for the repower and what type of vessel? I dont think Wartsila will bring out a new 620, only technical upgrades for engines already in service.
Problematic is a good way of putting it, this video was taken during a seatrial after replacing B3/A3 pistons & liners due to a siezure, but they are a big improvement over the old 604s

The air-cooled Deutz, like the air-cooled VW are so good that they discontinued making both of them. OK in their day, but way behind the times now.
