INJECTION NOZZLE PRESSURE TEST
1.
Position injection nozzle on a suitable injection pressure tester, Fig. 39.
2.
Operate injection pressure tester at approximately 60 cycles per minute and note pressure gauge readings. The reading should increase gradually,
with pointer oscillating when nozzle is injecting. The pressure gauge reading at the point where the gauge pointer starts to oscillate should be
1707-1849 psi. If pressure is below the service limit of 1565 psi or less, then nozzle must be disassembled and inspected.
