The scope of delivery includes clamping bushings
in the sizes 17 mm, 19 mm and 21 mm.
4. Select the correct clamping bushing (Fig. 5, item 4)
based on the diameter of the injector nozzle retai-
ning nut.
5. Insert the clamping bushing (Fig. 5, item 4) into the
injector clamping fixture.
i
CRINs with a test adapter (Fig. 7, item 3) are secu-
red without a clamping bushing.
6. Firmly press the injector nozzle of the CRI/CRIN or
piezo CRI into the injection chamber.
7. If necessary, adjust the height of the injection
chamber and secure with the clamping bolt
(Fig. 5, item 3).
8. Tighten the CRI/CRIN or piezo CRI with the clam-
ping bolt (Fig. 5, item 1).

ezo
!
Always use the connection adapter (Fig. 6, item 3)
when connecting the high-pressure hose assembly
(Fig. 6, item 5) to the CRI/CRIN or piezo CRI. Never
connect the high-pressure hose assembly directly
to the CRI/CRIN or piezo CRI. Always keep the con-
nection adapter clean.
The high-pressure hose assembly (Fig. 6, item 4) is
connected to the high-pressure connection of the CRI/
CRIN or piezo CRI by way of the connection adapter
(Fig. 6, item 3). The adapter (Fig. 6, item 2) must also
be used for connecting to the high-pressure connec-
tion with the M14x1.5 thread.
Tightening torque: 25 — 30 Nm.

If the connection adapter is leaking, replace it.
!
To prevent the high-pressure hose assembly from
twisting or being damaged, always connect the
connection adapter to the injector without the high-
pressure hose assembly first.
1. Attach the connection adapter (Fig. 6, item 3)
without the high-pressure hose assembly being
connected to the high-pressure connection of the
injector (Fig. 6, item 1).
Tightening torque 25 — 30 Nm
2. Connect the high-pressure hose assembly with the
