III. Critical Technician Notes (MUST-DO)

1. Injector Calibration: After nozzle replacement, perform injector coding and calibration (IMA/ISA) using diagnostic tools.
2. Sealing Components: Always replace copper washers and O-rings when reinstalling injectors.
3. Injector Bolts: Use new stretch bolts — never reuse old ones.
4. Clean Installation: Ensure a completely clean working environment; contamination can cause premature injector failure.
5. System Verification: Perform leak-back test, pilot injection calibration, rail pressure check, and full engine performance verification after installation.
