CUMMINS INJECTORS CD3 AUDIT KIT
Equipment Required
• Test gauge set
Set-up
1. Remove the injector, push rod link, and push
rod extension.
2. Open the door on the left side of the calibrator.
3. Connect the test gauge set to the high pressure
line quick connect. The fitting is located at the
pump driven by the main drive motor shaft.
4. Close the valve on the test gauge (black handle
across valve body).
NOTE: Be certain that the test gauge hose
does not interfere with drive belts.
Test
5. Run the calibrator. (Push the START MAIN
DRIVE button.)
6. Set the rail pressure gauge on the front panel
for 100 psi.
7. Check for any leakage in fluid lines or fuel arm.
Repair if necessary.
8. Open the valve on the test gauge set (black
handle in line with valve body). Pressure
should be between 400 and 410 psi.
9. If pressure is between 400 and 410:
a. Stop the main drive motor.
b. Wait until pressure gauge needle returns to
zero.
c. Skip the rest of this procedure and proceed
to Section 2.5.
10. If pressure is not between 400 and 410 psi:
a. Stop the main drive motor.
