1. Connect the hoses for the calibrating oil supply
(fig. 11, pos. 1) and return (fig. 11, pos. 2) to the
connections of the common rail pump provided for
this purpose (fig. 11, pos. 8).

For CP3.4 with the required return pressure < 10
kPa connect hose line (fig. 2, pos. 12).

Before connecting the high-pressure hose, clean the
sealing taper and sealing cone on the high-pressure
rail and high-pressure pump.
2. Connect the high-pressure hose 1 680 712 324 (fig. 11,
pos. 3) to the high-pressure inlet of the high-pressure
rail, and use the test pressure line 1 680 750 123
(fig. 11, pos. 4) to connect to the high-pressure
connection of the common rail pump (tightening torque
= 25 Nm – 30 Nm).
3. Connect X24 connecting cable 1 684 463 946
(fig. 11, item 6) to X24 at EPS 708 and via the
adapter cables 1 684 460 255 or 1 684 460 256
(fig. 11, item 7) to the electrical connection of the
common-rail pump.
4. Seal the connection for connecting the high-
pressure hose to the CRI 846H rail (fig. 11, pos. 5)
with a dummy plug.
"
The common rail pump is now hydraulically and
electrically connected.
