- The presence of exhaust smoke color.
Procedure: quickly accelerate engine.
Criteria: no remarkably black smoke exhaust, and correct function of fuel cut-off solenoid
-
Any leaks at the body injection pump or fuel lines.
MAINTENANCE TASK. INJECTOR INSPECTION
To check the injection pressure of injectors (opening
pressure) you have to follow these steps:
1. Remove nozzle and washer.
Fig. 29. Remove injector
2. Install the injection nozzle on the tester. Slowly operate the tester handle full strokes to bleed
(remove) air from the pipe and nozzle.
3. Make a slow increase in pressure by operating
the tester handle at a speed of more than one
stroke per second while observing the pressure
gauge.

4. The pressure gauge reading will slowly increase and, when the nozzle starts discharging fuel, it
will go down fast. Take the gauge reading right then as the injection pressure.
Injection pressure 13,73 MPa (140 kgf/cm

)
Table 12. Injection pressure
5. To adjust the injection pressure, increase or decrease
the amount of shims fitted to the nozzle holder.

6. Look at the orifice discharge pattern (shape of discharge) when fluid begins to flow through the
injection nozzle. The discharge must be finely and uniformly atomized. Any change is an
indication of a bad nozzle.
