3) Inspection and adjustment
●
Assemble the nozzle in the nozzle tester and operate the nozzle tester 2 or 3 times to bleed air. After
pressurizing it measure the nozzle pressure.
●
Re-check the injection pressure and see if the spray pattern is normal.
●
Adjust the injection pressure to the standard pressure using shims if the injection pressure is poor.
●
Nozzle opening pressure is adjusted by thickness of shims installed on the compress spring. There-
fore in case of low or high injection pressure, adjust by adding or reducing the spring tension adjusting
shims.
●
In case that atomizing state is not good it should be replaced.
●
After adjusting the injection pressure tighten the cap nut to specified torque.
Caution
As the fuel injection line is operated by high pressure, should pay particular attention to treat.
●
Fix the nozzle holder securely when assemble it.
●
Do not bend the injection pipe so much it as deformed severely.
●
Do not use the abnormal bending pipe preventing from cracking.
●
Do not bend the end portion of injection pipe over 2 or 3 degree to assemble it easily.
