Diesel drivetrain

[bsb369]

I have read that the Kubota diesel d600 is pretty close to the same torque and horsepower rating as the KT 17 kohler. But I have also read that because the torque of a diesel they are especially hard on the drivetrain??? If they are rated the same then why do diesels wear the drivetrain parts out more often than their gas counterpart?? Just a curiosity if anyone has an opinion.

i think you answered your own question more torque but also there is a slight angle to the driveline that helps wear it out

Ok I can agree with the angle of the drive shaft being different but the torque ratings for both engines are pretty much the same so the torque of the diesel shouldn't cause any more wear than the gas engine

torque is alot lower on a diesel, and can hammer stuff apart easier, has to do with the longer stroke and compression too.

Torque is higher on a diesel, not lower.... Diesels don't necessarily have a longer stroke, but the fuel injected burns twice as long as gasoline.

Simple answer: They vibrate more. More crank pulse from the diesel motor, and the fact it has 3 cylinders and not 2.

I appreciate the input just was curious as to why. I never thought about the vibration being more and the difference in the number of cylinders but it makes perfect sense now that I think about it.

oops worded that wrong, I meant lower rpm!

RPM is the same. Both engines run at 3600 at wot.....

the torque curve on a diesel starts at a lower rpm. also due to the higher compression, they pulse alot harder than a gas engine, and it can destroy stuff quicker.
