Fuel Injection Nozzle Tester
Notice: When testing the injection nozzle, do not place
your hand into the spray of a nozzle. The spray will
penetrate deep into the skin and destroy the tissue.
1. Connect the fuel injection nozzle to the fuel
injection nozzle tester 000 589 14 27 00.
2. Close the valve (3) and pump 5 times strongly.
3. Chatter test :
Slowly operate the hand lever at tester (approx. 1
stroke per second). The nozzle must spray with a
gentle chattering.
•
Poor
The spray pattern shows split, too wide and
stringy.
(Repair the fuel injection nozzle)
4. Spray pattern test :
Operate the hand lever at tester rapidly (approx.
2~3 strokes per second).
•
Good
The spray pattern shows closed and well
atomized.

5. Opening pressure test :
Open the valve (3) and slowly operate the hand
lever at tester (approx. 1 stroke / second) and
measure opening pressure.
Notice: If out of standard, repair the injection
nozzle.
6. Leak test
Slowly operate the hand lever at the tester until
get a pressure of approx. 90 bar. Maintain this
pressure for more than 20 seconds and within this

CHECKING AND ADJUSTING START OF DELIVERY
Governor Impulse Method (RIV)
1 Fuel Injection Pump
2 Rl Sensor
3 Digital Testor
In order to obtain a measuring signal the sensor pins
must be moved past the pulse generators with a
minimum speed (idle speed). A measuring instrument
measures the time interval of the two impulses,
converting the result into an angular value which is
then indicated.
4 TDC Pluse Sender Unit
5 Battery
YAD1FBF0
In order to be able to register the relationship of the
injection pump relative to the engine two signals are
required.
•
TDC impulse from the crankshaft.
•
Governor impulse from the injection pump.
Both impulses are supplied by pulse generators.
