CD3 AUDIT KIT CUMMINS INJECTORS
12. Purge air from the line and tester by momen-
tarily depressing the bleeder valve pin (quick
connect) located 90° from the fluid inlet.
Test
NOTE: During the test, keep the weight (top
portion of the dead weight tester) spinning
to reduce friction and increase accuracy. Be
certain no leakage occurs around the fuel
arm connection to the dummy injector.
13. Slowly turn PRESSURE REGULATOR knob
clockwise until the dead weight begins to rise.
14. Place the trim weight on dead weight tester.
The weight should slowly fall.
15. Adjust the pressure regulator until both condi-
tions (steps 13 and 14) are obtained at one
setting of the regulator.
16. Remove trim weight. The weight should rise.
17. Repeat steps 13 and 14 to check setting.
18. Tighten the lock nut on the regulator while
holding the PRESSURE REGULATOR knob
from turning.
After final adjustments, the console-mounted
pressure gauge should read exactly 100 psi.
19. If the gauge does not read 100 psi, adjust the
gauge needle as required to read 100 psi:
a. Remove the glass over the gauge by loosen-
ing the thumbscrew on the bezel and
pulling the bezel away from the gauge.
b. Insert the rail pressure gauge adjusting tool
in the hole on the needle and turn as
required to set the needle at 100 psi.
c. Remove the tool and replace the bezel.
20. Set 250 ml graduated cylinder on drain tray.
21. With the stopwatch in one hand and the drain
tube from the bottom of the dummy injector in
the other, fill the graduate for 20 seconds.
22. Read the volume of fluid from the scale on the
graduate. Be sure to read the bottom of the
meniscus. Volume should be between 176 and
179 cc(ml). Figure 2-27. Filling Graduate
