All were good motors that ran for thousands of hours, lots of parts, but more expensive to overhaul than a Cat. because you have to throw away a lot more parts than with a Cat. If you need a motor to push 60 tons, you need a Cat.
as a side note a new from the factory 3408TA latest version is 67 thousand dollars and that's minus the reduction gear and a lot of other parts to get the thing operational, so don't complain too much about the price of fish, you just have to buy the fish, not the Cat.
