CFP83-F40
The C8.3 is built to last, with a cast-iron unitized block with fewer parts than traditional diesel designs, fewer joints and simplified maintenance. This block has been structurally reinforced to resist bending and torsion, eliminating 1 dBA of noise output. Even the gaskets have a special edge-molded design to eliminate possible leakage and reduce oil consumption. Heavy-duty features include:

• EPA Tier-2 exhaust emission certified
• Heavy-duty pistons with Ni-Resist inserts for longer life
• Mid-stop cylinder liners that reduce cavitation and improve rebuild ability
• 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
• The Cummins 8.3L Series engine is a 4 stroke inline. It has a 505cu.in.(8.3 liter) displacement.
• The operating speeds are as follows: 1470RPM / 247hp(184kW);
  1760RPM / 288hp(215kW)
