OPERATION
The gauge reading will decrease from the green

The injector is now ready for testing (Section 3.2.7).
3.2.7 Testing
WARNING:
HAZARDOUS ROTATING MACHIN-
ERY. Do not open cambox cover while
main drive motor is running.
NOTE:
When starting main drive for the

Before testing Detroit Diesel Corporation injectors
please read the following:
IMPORTANT NOTE:
I
t was recognized that testing unit injectors
(manufactured by Diesel Technology Corporation
for Detroit Diesel Corporation (DDC) engines) the
results can be different from those obtained on other
makes and models of calibrators.
In particular, it has been determined that Master
Injectors marketed by Kent Moore all read higher on
the Bacharach CD3 Calibrator by the amount
shown below. Therefore, when checking Master
Injectors, the fuel output as read on the digital
readout of the CD3 Calibrator will be higher than
the stamped values by the amounts shown:
Injector Type
Difference In Reading (mm³/str)
53
2.0
71
2.5
92
4.6
8.2L
2.3
149
3.9
The recheck limits (as given by DDC) of Master
Injectors on any calibrator are ±2% of stamped
value. As an example, for the type 71 Master
Injector:
