Usage:
Bench test nozzles using Kent-Moore J23300-585 or Shell 66631 calibration oil or equivalent at ... 65° to 70° F(18° to 20° C).
Nozzle setting pressures (valve lift adjustment screw turned 3/4± 1/8turn from closed position):
New nozzle ... 2750 to 2900 psi(193.3 to 203.9 kg/cm2)
Used nozzle ... 2400 to 2900 psi(168.7 to 203.9 kg/cm2)
Used, adjusted nozzle ... 2700 to 2900 psi(189.8 to 203.9 kg/cm2)
Return oil leakage test pressure ... 1400 to 1600 psi(98.4 to 112.5 kg/cm2)
Leakage in 15 seconds ... 1 to 10 drops
Maximum tip leakage is 3 drops in 15 seconds with pressure 250 to 300 psi (17.6 to 21.1 kg/cm2) less than opening pressure.
