Check
1.
Carbon deposits (Flowering)—carbon deposits build up on the nozzle in the form of flowers.
Flowering lowers combustion performance significantly. Make sure the nozzle is free from
contamination.
2.
Shape of injection spray—move the lever of the nozzle tester at a speed of approximately 1.2
time/sec. to check the spray pattern.
Normal shape of spray
1.
The spray should all be at the same angle (from all four injection ports).
2.
The spray should be a fine mist.
3.
The spray should be smooth and steady without deviations (4 nozzles).
CAUTION:
When installing fuel injection valve:
1.
Tighten the fuel injection valve assembly to the specified torque.
2.
Clean the sleeve surface. Be sure to replace the nozzle gasket at the same time.
NOTE:
If nozzle gasket stays in cylinder head after injection valve assembly has been removed from cylinder
head, screw M8 or M9 stud bolt (more than 100mm long) in nozzle gasket, then pull out stud bolts to
remove gasket.
4.11 Disassembly and Reassembly - Case Nut
Remove the case nut and then all parts of the valve can be disassembled.
To disassemble and reassemble the case nut, use a 15mm deep socket wrench. The fuel valve
positioning pin does not need to be removed in most cases.
4.11.1 Adjustment
The injection starting pressure is 200 kg. To adjust the nozzle injection starting pressure, remove the
nozzle holder and increase or decrease the number of adjusting shims.
