Included in accessory set 1 687 010 594 (non-Bosch CRI acces-
sory set).
i
For non-Bosch CRIs, accessory set 1 687 010 594 is
required (optional accessories).
i
The prerequisites to be observed when checking
and adjusting the Bosch piezo CRI can be found in
the test instructions for piezo CRI in ESI[tronic] 2.0.
These test instructions do not form part of the scope
of delivery. ESI[tronic] 2.0 can not be installed on the
EPS 118.

Procedure:
1. Clean the CRI/CRIN, piezo CRI (see sec. 7.3).
i
When the CRIN has internal connections, the CRIN
must be installed in the test adapter before clamp-
ing (see sec. 5.4.8).
2. Clamp the CRI/CRIN, piezo CRI (Fig. 34, item 5)
(see sec. 5.4.6).
!
To avoid twisting and premature wear, do not con-
nect the high-pressure hose assembly directly to the
injector. Always connect the high-pressure hose as-
sembly to the connection adapter for the CRI/CRIN
or piezo CRI on the injector (see sec. 5.4.7).
!
The connection adapter for CRI/CRIN and piezo CRI
must be tightened to a torque of 25 Nm to 30 Nm.
If the connection between the connection adapter
and the injector is leaking, the screw connection is
not to be re-tightened. In the event of a leak, unfas-
ten the connection again, clean the sealing surface
and re-connect the connection adapter applying the
correct tightening torque.
3. Connect adapter M12 — M14 (Fig. 6, item 2) to the
high-pressure connection of the injector (only neces-
sary when the high-pressure connection has threads
measuring M14x1.5).
Tightening torque 25 — 30 Nm
4. Connect the connection adapter (Fig. 34, item 7) to
the high-pressure connection of the CRI/CRIN/piezo
CRI or adapter M12 — M14.
Tightening torque 25 – 30 Nm.
!
The smallest permissible bending radius of the
high-pressure hose assembly is 90 mm.
!
The high-pressure hose assembly should not come
into contact with the protective hood.
5. Connect the high-pressure hose assembly to the
high-pressure connection (Fig. 34, item 2).
Tightening torque 25 – 30 Nm.
6. Connect the other end of the high-pressure hose as-
sembly to the connection adapter (Fig. 34, item 7).
Tightening torque 25 – 30 Nm.
