Building on the JD14 engine design from John Deere, the JD18 engine was engineered with flexibility, serviceability and durability in mind. The JD18 extends the rated power range to 522 – 676 kW (700 – 907 hp). The engine features a rear gear train, which produces direct power and options up to two rear aux drives for a total of 902 Nm (665 lb-ft) max torque providing quiet operation.
Other key features include:
Uptime focused controls
John Deere controls offer diagnostic capabilities, enabling future prognostics, and the ability to target the source of engine performance issues.
The JD18 features a bedplate design, providing structural benefits for durability, with the ability to be re-built two times.
Serviceability and repairability
The JD18 engine was designed with the ease of service and repair in mind, with hydraulic lash adjustment (HLAs), which offers a maintenance-free valvetrain, eliminating the need to reset the lash.
The JD18 features new combustion technology, which allows John Deere to offer an engine in the 522 – 676 kW (700 – 907 hp) power range without aftertreatment. Without the need for DEF, users have one less fluid to manage. The high-pressure common-rail fuel system allows the engine to deliver optimized fluid consumption. And the diamond like coating improves bio-diesel compatibility and system robustness.
The new combustion technology offers a simplified air system, with fixed and wastegate turbos, allowing the engine to meet emissions requirements without applying aftertreatment. This feature provides a simplified engine integration and package size.
The addition of the JD18 to the John Deere engine range enables users to put John Deere power and performance into their entire lineup of equipment from 36 kW (48 hp) to 676 kW (907 hp).
