CD3 AUDIT KIT DETROIT DIESEL INJECTORS
Skip this test if you have already done it for Cum-
mins injectors, otherwise follow the procedure in
Section 2.8.
3.6 DD MASTER INJECTOR FLOW TEST
Equipment Required
• Master injectors, Kent Moore part J26298 for
53, 71, and 149 injectors
• Master injector, Kent Moore part J29898 for
8.2L injector
Set-up
1. Set up the calibrator to run DD injectors
following the procedures given in the CD3
Instruction Manual.
Test
2. Run each master injector repeatedly until
readings stabilize.
3. After readings stabilize, record at least five
consecutive readings per injector.
IMPORTANT NOTE:
It was recognized that testing unit injectors (manu-
factured 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
Bacharach CD3 Calibrator by the amount shown
below. Therefore, when checking Master Injectors,
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
