Features

High-pressure common-rail (HPCR)

  • Provides more flexible injection timing and higher efficiency. Rear gear train and HPCR reduces noise by up to 3 decibels.

4-valve cylinder head

  • Excellent airflow through 4-valve cylinder head delivers greater low-speed torque and better transient response time.

Water-cooled exhaust manifold

  • Integrated components eliminate external hoses and fittings. Wet exhaust manifold creates a cooler and quieter environment for passengers and crew.

Turbocharged, air to coolant cooled with separate circuit

  • Cooler turbocharger operation enables higher ratings and efficiencies for applications that require high power or speed.
  • Jacket water cooling system with separate circuit to assure salt water can't enter the combustion system.

Hydraulic automatic valve lash adjustment

  • Provides durability and eliminates valve lash maintenance.

Extended service intervals

  • Longer service intervals with use of John Deere oil. Rigid bronze impeller on sea water pump with up to 10 000-hour life before needing maintenance.

John Deere Connected Support™

  • Remote monitoring and diagnostics comes standard. Provides protection and efficiency with no subscription fees or ongoing expenses.
