Cummins NT855-G6 Diesel Engine
The Cummins NT-Series engines have been service proven through millions of hours of operation in some of the world’s most demanding applications. The 14 litre, six-cylinder NT855 has been engineered to handle higher injection pressures, with redesigned overhead arrangement, pistons, crankshaft and camshaft. A gear train with high contact ratio spur gears also eliminates unwanted thrust loads and reduces noise.
