(2) Adjustment
Remove the cap nut and assemble a
nozzle to a nozzle tester.
With the adjusting screw loosened,
operate the nozzle 2 ~ 3 times to bleed it.
Operate the nozzle tester lever at the
specified rate.
Adjust the injection pressure to the
standard pressure using the adjusting
screw.
After adjusting the injection pressure,
tighten the cap nut to specified torque.
Re-check the injection pressure and see
if the spray pattern is normal. Spray
pattern should be uniform and free of
spattering.

With the nozzle assembled to a nozzle tester and specified pressure applied, check the nozzle for
fuel leakage.
If the joints are free from leaks and the
