TM5-6115-593-34 NAVFAC P-8-631-34 TO-35C2-3-463-2 (6) Jet fuel source pressure to 22 psi (152 kPa). (7) Shift the target ring in base of tool so one spray stream hits center of No. 1 or index window. This window provides ±3 degrees tolerance on injector spray stream location. (8) Check that spray stream hits a window in the target ring. No more than one stream must require the increased tolerance of the No. 1 window. (9) After testing, assemble plunger with spring in body adapter and store in clean place until ready for next test. c. Flow Test. The flow test is accomplished using the injector test stand (see figure 13-19).Refer to paragraph i, and proceed as follows: (1) Seat injector in body so injector inlet aligns with body inlet hole. Tighten locating screw. (2) Remove spring (4) and plunger (7) from injector adapter. Leave spring (4) off and install plunger (7). (3) Attach test stand inlet pressure line to drain connection of test stand. (4) Hold injector plunger down against its seat in injector cup with injector in a vertical position. Assembly may be held in hand; do not place in test stand holding device. (5) Turn on test stand and adjust pressure to 150 psi (1034 kPa). (6) Check orifice plug inlet opening or injector for leakage past ball valve. NOTE Make certain that plunger is seated in the cup. (7) If leakage is observed, the ball (8) must be replaced. Slight seepage is harmful. d. Disassembly. Proceed as follows: (1) Lift out injector link (3), plunger (7), and spring (4). Remove spring (4) from adapter (15). (2) If required, store plunger (7) by standing on coupling end. NOTE Injector barrels and plungers are class fit. Do not interchange. (3) Remove O-rings (10) from injector adapter (15) and discard. (4) Remove filter screen clip (11) and remove screen (12). Check screen and discard if damaged. NOTE Do not remove orifice plug (13) from inlet groove. (5) Insert injector into holding fixture. (6) Slide body wrench, over flats on injector. (7) Place retainer wrench on injector. (8) Activate air cylinder on holding fixture to hold injector in place. Loosen cup retainer (5) but do not remove. (9) Deactivate air cylinder. (10) Remove injector clamp and retainer wrench from fixture. (11) Screw off cup retainer (5) and remove injector cup (6) and barrel (7). NOTE Do not lose check ball (8) 13-31
