TESTING - Continued NOTE After needle valve opening pressure test is complete, continue injector assembly. 6. Injector holding pressure check procedures: a. Place fuel injector in diesel fuel injector test fixture (Figure 17, Item 39). b. Operate pump handle (Figure 17, Item 40) until test gage (Figure 17, Item 45) pressure reaches 2200 psi (15168 kPa). c. Close fuel shut off valve. Start timing when pressure reaches 2000 psi (13789 kPa) and stop at 1500 psi (10342 kPa). Minimum time is 5 seconds. d. If pressure drops in less than 5 seconds, check for leaks around spray tip, preformed packing, and fuel connectors. e. Pop fuel injector several times with popping handle (Figure 17, Item 38) until test gage (Figure 17, Item 45) shows no pressure to avoid fuel spray when removing injector from diesel fuel injector test fixture (Figure 17, Item 39). 7. Cover injector ports to prevent dirt from entering injector. D D C B B A A C MAINT_289 Figure 17. Fuel Injector Pressure Test. END OF TASK FOLLOW ON TASK Install injectors (WP 0083).
