CUMMINS INJECTORS CD3 AUDIT KIT
15. Read and record the contents of the graduate
while it is sitting on a level surface. Be sure to
read the bottom of the meniscus.
16. Repeat the test three times, cleaning the
graduate for each test.
Although the graduate scale is in ml or cm³ (cc) and
the flowmeter display indicates mm/stroke, the
numbers should be within ±5.
For examples if the average display reading is
150.3 mm/stroke, the graduate reading should be
between 145.3 and 155.3 ml.
The results should be consistent. If these results
cannot be obtained, see the troubleshooting section
of the CD3 manual.
17. Remove all test equipment and return it to the
Audit Kit case.
18. Insert drain tube into reservoir (removed in
step 3).
2.7 BODY TO SEAT CLAMP FORCE TEST
Proper body to seat clamping assures good sealing
of the Cummins injector to the discharge head. This
sealing is required because high pressure is devel-
oped between the Cummins injector and the dis-
charge head. Low clamping force may cause leak-
age which in turn will affect fuel output readings.
Equipment Required
• Load cell assembly
• Clamp force and temperature indicator
• Discharge head, (Cummins)
Set-up
1. Place the flywheel in top dead center position
(the white area will show through the window).
2. Place the discharge head in position.
3. Place the load cell assembly in position.
4. Connect the load cell assembly cable to the
clamp force and temperature indicator.
5. Push and hold the HOLD TO OPERATE
button.
