The C8.3 is built to last, with a cast-iron unitized block with fewer parts than traditional diesel designs, fewer Cummins Pump Engine 6C8.3 joints and simplified maintenance. This block has been structurally reinforced to resist bending and torsion, eliminating 1 dBA of noise output.

Heavy-duty features include:

•  Heavy-duty pistons with Ni-Resist inserts for longer life
•  Mid-stop cylinder liners that reduce cavitation and improve rebuildability
•  Plateau honing on the cylinder liners for near-perfect cylinder geometry, virtually eliminating oil consumption
•  A robust Holset HX40 wastegated turbo with excellent low-end torque
•  An in-line fuel pump that delivers higher injection pressures for cleaner combustion, more power and flexible fueling
•  A helical gear train that operates smoother and quieter
•  A proven design with millions of C Series engines in service everywhere around the world
