Key Specifications

The C8.3 is built to last, with a cast-iron unitized block with fewer parts than traditional diesel designs, fewer Cummins Pump Engine 6C8.3joints 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
