Features

Expand All Collapse All

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 Sea Water Cooled

Cooler turbocharger operation enables higher ratings and efficiencies for applications that require high power or speed.

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.
