III. Critical Technician Notes (MUST-DO)

1. Injector Calibration: After nozzle replacement, perform injector coding and calibration (IMA/ISA code entry) using diagnostic tools.
2. Sealing Components: Always replace copper sealing washers and O-rings.
3. Injector Bolts: Clamp bolts are single-use stretch bolts — replace with new ones at every installation.
4. Clean Installation: Maintain absolute cleanliness during assembly; even micro-particles can damage CR nozzles.
5. System Verification: After installation, perform leak-back test, pilot injection calibration, rail-pressure and performance checks.
