Ski and Mako,
In the old days, Deutz diesels had balancing shafts driven off the engine, internal to the block. For some reason, they didn't put them on 'Industrial' engines saying that if it is mounted to a concrete pad a little extra vibration is no big deal. I disagree.
A SISU engine is an Agco engine, and Agco is a conglomerate that includes Deutz.
So, it may or may not have the counter balance shaft installed.
Also, most of my Deutz work was over 40 years ago, so things may have changed
Deutz engines had the best power and fuel consumption for many years until they ran into some miss-management problems. One interesting side note is that John Deere's factory is not far from Deutz and whenever Deutz had layoffs, JD would hire the engineers. Deutz complained to the courts but was laughed at. If you're not paying your engineers, they are free to go wherever they want....
So, as a result, John Deere's overall performance and efficiency has seen over 2x improvement in 30 years.
Also, the Deutz engine powered the Tiger tank used by Germany to fight world war II, using far less fuel than the GM designed American tanks. Also, since it was air cooled, no one could shoot out the radiators.
History class is adjourned.
