TM 9-6115-604-34 NAVFAC P8-633-34 Figure 6-28. Fuel Arm and Supply Valve (18) The injector flow per 1000 strokes should be 284.5 to 286.5 cc. (19) It the injector over 286.5 cc, install a metering orifice as follows: CAUTION To avoid damage to the test stand, do not leave the injector clamped more than 1 minute after stopping the main drive. Do not, however, unclamp the injector until the main drive motor has stopped. (a) Raise the fuel arm (21, Figure 6-20), wait until the main drive motor stops, then release the damping control the guard (20) and raise the guard (23). (b) Remove the orifice (10, Figure 6-21) from the adapter (17) using a 5/64 inch hex head driver. Remove and discard the orifice plug gasket (11). NOTE Orifices are available in sizes 0.029, 0.030, 0.031, and 0.032. (c) Select a smaller orifice (10), and install a new orifice gasket (11 ) and the smaller orifice in the adapter (17). Tighten the orifice to 8 to 10 pound-inches (0.90 to 1.13 newton-meters). (d) Recheck the injector flow in accordance with steps (14) through (17), above. 6-53
