3. Replace the O-ring on the injector nozzle seat
(Fig. 4, item 2) with the one needed (D7 or D9). To
replace the O-Ring, use the removal tool
(Fig. 4, item 1).

Depending on the diameter of the injector nozzle
retaining nut (17 mm / 19 mm / 21 mm) or test
adapter of the CRI/CRIN or piezo CRI, it may be
necessary to exchange or remove the clamping bush
(Fig. 5, item 2) in the injector clamp.
i
CRIN injectors with a test adapter (Fig. 7, item 3)
do not need a clamping bush.
4. Insert the right clamping bushing (Fig. 5, item 4)
into the injector clamp.
5. Shove the CRI/CRIN or piezo CRI into the clamping
blush.
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 cham-
ber and secure with the clamping bolt
(Fig. 5, item 3).
8. Tighten the CRI/CRIN or piezo CRI with the clamping
bolt (Fig. 5, item 1).

5.4.7 Connection adapter for CRI/CRIN and
CRI Piezo
!
Always connect the high-pressure hose assembly
(Fig. 6, item 5) to the CRI/CRIN or piezo CRI by
way of the connection adapter. Never connect the
high-pressure hose assembly directly to the CRI/CRIN
or piezo CRI. Always keep the connection adapter
clean.
The high-pressure hose assembly (Fig. 6, item 4) is con-
nected 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 connection
with the M14x1.5 thread.
Tightening torque: 25 — 30 Nm.

To prevent the high-pressure hose assembly from
twisting or being damaged, the connection adapter
and then the high-pressure hose assembly must be
connected.
1. Attach the connection adapter (Fig. 6, item 3) with-
out the high-pressure hose assembly being connect-
ed to the high-pressure connection of the injector
(Fig. 6, item 1).
Tightening torque 25 — 30 Nm
