Features & Benefits

Directed Top-Liner Cooling

• Directing coolant to upper end of the liner reduces liner temperatures by up to 100°F (54°C), improving power cylinder durability, head gasket life, and reducing oil consumption and emissions

SAE J1939 Standard Communication Link

• Industry standard, which provides an interface with vehicle systems, like transmission, hydraulics and various accessory drives minimizing machine complexity and reducing vehicle total installed cost

John Deere Electric Controls

• John Deere electronically controlled fuel systems monitor critical engine functions and either derates or shuts down (override capability provided) and engine to prevent costly engine repairs
• Built-in controls eliminate need for costly add-on engine warning/shutdown systems and associated devices
• Service diagnostics and error codes automatically stored for later retrieval, increasing machine uptime
• Performance connector part of engine wiring harness which allows for programming of multiple power curves and droop or isochronous governor regulation

Either-Side Service

• Combination oil fill/dipstick available on either side of the engine, greatly simplifying engine installation

Gear auxiliary drive

• Left hand gear auxiliary drive available which provides up to 60 hp (45 kW), intermittent

Self-adjusting Poly-vee Fan Drive

• Self-adjusting, eight-groove, poly-vee fan drive provides multiple fan drive ratios and fan heights that can be matched to specific application requirements
• Poly-vee design provides more than twice the drive capacity of comparable vee-belts

Additional Features

• 8.1L engine includes gear-driven water pump, improved accessory mounting, gear-driven auxiliary drive, self-adjusting poly-vee fan drive, air compressors, and high-mount A/C compressor options

Optional Rear PTO

• Rear PTO is an integral part of the flywheel housing and provides a means for driving medium/large hydraulic pump(s), and air compressors
• Available in SAE #1 or SAE #2 flywheel-housing configuration for dry applications
• 1.3:1 output ratio allows the use of smaller, higher speed hydraulic pumps
• Gear train, pump drives, and flanged output drive are capable of up to 300hp/224kW (750 ft-lbs/1018 N.m torque) on an intermittent basis
• Right-hand side pad standard with optional left-hand side pad
• SAE standard "C" and optional "B", "D" mounting pads and flange output drives
