Assemble the injector nozzle. Connect the nozzle to the tester with the nozzle down [Figure 70-70-38].
Operate the hand lever at a slow rate and record the opening pressure. If the pressure is not correct, disassemble the nozzle and add or remove spacers (Item 2) [Figure 70-70-37] as needed.
When the injector nozzle is assembled, tighten the nozzle body to 43-58 ft.-lbs. (59-79 Nm) torque.
