Product Overview
A worn or damaged injector can contribute to hard starting, uneven combustion, smoke, loss of power, fuel knock, or a dead cylinder. Injector condition should be considered alongside compression, fuel pressure, pump timing, and the rest of the fuel system.
These John Deere mechanical diesel families use application-specific pencil nozzles. Replacement catalogs commonly associate this configuration with RE36939, RE38087 and SE500819, but the engine build and original nozzle number should be used to distinguish it from turbocharged/PowerTech injector variants.
Key Features & Performance
- Metered fuel delivery: Designed for the matching diesel injection system and engine family.
- Cylinder-level service: Allows the failed injector or injector set to be replaced when testing identifies a fueling problem.
- Reference-number matching: Injector families can look similar, so the stamped/OE number and engine arrangement are important fitment checks.
Part Numbers & Specifications
- Common Reference Family: RE36939; RE38087; SE500819
- Injector Style: Pencil-type mechanical diesel injector
Before You Order
Read the number from the original injector or engine parts catalog and confirm the exact engine suffix. Do not substitute a turbocharged or different-calibration nozzle solely because the base engine displacement matches.
