Dhk/Ui Test Procedure - Bosch 1 687 010 398 Original Instructions Manual

en 30 | 1 687 010 398 | Operation
Procedure:
1. Clean the CRI (see Sec. 4.3).
i
Perform the "leak test" before fitting the injection
chamber (Fig. 19, item 4) on the CRI.
2. Attach the CRI (Fig. 19, item 5) to the clamp .
!
To avoid twisting and premature wear, do not con-
nect the high-pressure hose directly to the CRI.
3. Connect the high-pressure hose with the connection
adapter (Fig. 19, item 6, 7) to the CRI.
!
The connection adapter must be tightened to a torque
of between 25 Nm and 30 Nm. If the connection be-
tween the connection adapter and the CRI is leaking,
the screw connection is not to be re-tightened. In the
event of a leak, unfasten the connection again, clean
the sealing surface and re-connect the connection
adapter applying the correct tightening torque.
4. With Bosch CRIs, plug the adapter with check valve
into the "test connection for return quantity" (fig. 19,
item 1).
!
Do not use the adapter with check valve with third-
party CRIs.
5. Connect the hose assembly 1 680 712 287 to the
return of the Bosch CRI and the adapter with check
valve or, with a third-party CRI, to the "test con-
nection for return quantity" (fig. 19, item 1) of the
EPS 200.
6. Connect the injector-specific adapter cable
(1 684 465 841, 1 684 465 842) to the CRI and to
the "Socket" (Fig. 19, item 3).
!
Route the injector-specific adapter cable such that it
does not come into contact with the hot hoses.
7. Insert the inlet filter in the "Test connection for
injected fuel quantity" (Fig. 19, item 2).
8. Perform the test.
i
After the "leak test", the injection chamber
must be fitted on the component and the hose
1 680 712 362 connected to the quick-release cou-
pling of the injection chamber (fig. 19, item 4)and
via the inlet filter to the "Test connection for injected
fuel quantity" (Fig. 19, item 2).
i
CRI testing is described in the Online Help.

The prerequisites to be observed when checking and
adjusting DHK/UI can be found in the test instruc-
tions for DHK/UI in ESI[tronic] 2.0. These test in-
structions do not form part of the scope of delivery.
ESI[tronic] 2.0 can not be installed on the EPS 200.
