4.1.1.4 ADJUSTING THE INJECTION VALVE

CHECKING THE OPENING PRESSURE

NOTE: Use only test oil acc. to ISO 4113 or diesel fuel for the test.

CAUTION: When checking injection nozzles, take care that the fuel jet does not hit the hands. Due to the

high pressure, the fuel can penetrate the skin and cause severe injuries.

- Install the injection nozzle on the nozzle tester.

- Press the lever down slowly. Read the pressure at the start of fuel ejection and adjust the pressure, if

necessary, by changing the shims.

Specified pressure

New injection nozzles 260

bar

Pressure for re-usability 255

bar

ADJUSTING THE INJECTION NOZZLE OPENING PRESSURE

- Clamp the holder 110110 for the injection valve in a vise.

- Place the top part of the injection holder into the holder 110110 and unscrew the union nut.

Sequence of disassembly:

1. Union nut

2. Injection nozzle

3. Intermediate piece

4. Pressure spindle

5. Compression spring

6. Shims

7. Nozzle body

- Adjust the pressure by fitting the correct shim. The thicker the shim,

the higher the opening pressure will be. Re-assemble the injection

valve. Tighten the union nut to a torque of 40 - 50 Nm. Check the

injection valve with the nozzle tester.
