Set fuel injection pump per calibration chart specifications and settings in para. 2-33, 2-34, or 2-35.
Secure throttle positioner arm in Wide Open Throttle (WOT) position.
Turn calibration fluid pressure regulator fully counterclockwise.
Press calibration fluid system on pushbutton.
Adjust calibration fluid pressure regulator knob clockwise until 4.5-5.5 psi (31-38 kPa) is indicated
on the Cathode Ray Tube (CRT) monitor. Apply 17.6 volts by adjusting the variable DC voltage
supply knob to energize the electric shutoff solenoid.
Be aware that under no circumstances should the transfer pump
pressure exceed 130 psi (896 kPa). Excess pressure will damage
Turn on main drive system by pressing main drive on pushbutton and holding button depressed for
a minimum of three seconds. Increase pump speed to approximately 150 rpm to prime transfer
pump and bleed air from the high-pressure fuel line nuts at each test nozzle.
Increase pump speed to 1000 rpm. Ensure throttle lever is secured in WOT position. Run pump
approximately 10 minutes to warm the calibration fluid to 110°-115°F (43.3°-46.1°C) and bleed all
air from test stand and fuel pump. Observe transfer pump pressure reading on CRT monitor. It
should be 70-76 psi (483-524 kPa).
