DETROIT DIESEL INJECTORS CD3 AUDIT KIT
Test
7. Aim tachometer lightbeam at the perforated
window and read RPM. (Consult the tachom-
eter instructions if any problems with the
reading occurs.)
8. Record reading.
9. Press the STOP button.
10. If RPM is 2000 ±5 rpm, skip to step 12.
11. If RPM is not 2000 ±5 rpm:
a. Make sure the motor matches the line
frequency (see specifications on the name-
plate inside left side door).
b. Operate the calibrator without an injector
installed and without push rod adapters.
c. Recheck the speed with a tachometer.
d. If problems still exist, check the drive shaft,
pump shaft or motor shaft binding and
replace necessary parts.
12. If speed is normal, turn the circuit breaker
OFF.
3.1.2 Using a Mechanical Tachometer
Set-up
1. Switch circuit breaker OFF.
2. Remove the pulley cover.
NOTE: Older units (shown in the photos)
using a sliding pulley cover (newer units
have no side rails), slide the cover
backward until the track is disengaged.
3. Standing behind the machine, locate the
camshaft center hole on end of camshaft.
When performing tests, the end of the tachom-
eter will be pressed against the end of the shaft
at this point. The tachometer must be held in
line with shaft center for accurate reading.
4. Locate the cover interlock limit switch on the
calibrator table top just behind the drive shaft
next to the cover latch plate.
