Checking the injection nozzles
Pressure check
☞
Ball-type cock on fuel filter in the “OFF” position
☞
Clean the area around the nozzles
☞
Remove the injection line and the injection nozzle
☞
Connect the injection nozzle with the high pressure line of the nozzle tester
☞
Slowly increase pressure until the nozzle ejects fuel and read the pressure off the pres-
sure gauge
☞
If the injection pressure is too low, replace the spacer in the nozzle by a thicker one. If
the pressure is too high, replace the spacer by a thinner one.
➥
Injection pressure:
118 – 128 bar (1713 – 1858 psi)
• Spacer thickness of 0.1 mm (0.004”) corresponds to modification by 6.9 – 9.8 bar (100
– 142 psi)
• Check the pressure again
• Check the injection nozzle for drips after it has ejected fuel
☞
Create a pressure of about 20 bar (290 psi) below injection pressure and check
whether fuel drips from the nozzle
• Install the nozzle
• Open the ball-type cock on the fuel filter again
