Product Features for John Deere 9R 390 4wd Track Tractors: 

  1. Robust Design:
    • Stronger castings, beefier bearings, and more robust internal components ensure durability and reliability in field operations.
  2. Fuel Efficiency:
    • High-pressure common rail (HPCR) fuel system replaces fuel injectors and eliminates the need for a diesel particulate filter (DPF), resulting in improved fuel efficiency and lower operation costs.
  3. Serviceability:
    • Integrated coolant and oil passages, along with a new belt-driven water pump, reduce potential leak points and allow for easier serviceability.
    • Hydraulic valve lash adjusters maintain valve-lash settings during engine operation, reducing valve train noise and wear.
  4. Enhanced Cooling:
    • Hydraulic fan drive improves cooling capacity with no required maintenance.
  5. Improved Wiring Harness:
    • New integrated wiring harness design with a modular layout reduces vibration, enhances reliability, and simplifies service and diagnostics.
  6. Reduced Noise:
    • Rear gear train integrated fully into the cast-iron block reduces engine noise and enhances durability of the crankshaft damper.
  7. Performance Comparison:
    • The JD14 engine offers 14 percent more power and 11 percent more torque compared to the 13.5L (824-cu in.) engine.
    • It consumes 3 percent less fuel, weighs 10 percent lighter, and reduces mean repair time by 13 percent, resulting in estimated savings of $8,308 in service costs over the engine’s life.
  8. Comparison with 13.5L Engine:
    • The JD14 engine features an HPCR fuel delivery system compared to electronic unit injectors (EUI) in the 13.5L engine.
    • It has one canister for aftertreatment compared to two canisters in the 13.5L engine.
    • Valve lash adjustment is automatic in the JD14 engine, while it’s manual in the 13.5L engine.
    • Engine brake is available in the JD14 engine above 402.7 kW (540 hp), but not available in the 13.5L engine.
    • The JD14 engine has a different wire harness configuration, water pump, gear train position, and fan drive system compared to the 13.5L engine.
