Note:
The high-pressure pump is fitted on the gear side
with an adapter ring (1) and an O-ring (2) in the
timing gear case. If the removal of the high-
pressure pump is particularly difficult, it may be
necessary to press the adapter ring (1) carefully
out of the timing gear case using a small pry bar.
Installing the high-pressure pump
1. Clean the high-pressure pump. Make sure
that no dirt or cleaner can get into the high-
pressure pump ducts.
2. Check the high-pressure pump and the drive
gear (externally) for wear and damage.
3. Fit a new O-ring (2) on the adapter ring (1)
and apply a thin layer of engine oil to the O-
ring.
4. Fit the high-pressure pump and press it into
the timing gear case by means of the
attachment nuts.
5. Tighten the attachment nuts to the specified
torque. See "Technical data".
6. Fit the filter head and the fuel fine filter.
7. Fit the high-pressure pump to the fuel rail
and tighten the unions. See "Technical data"
for the specified tightening torques.
8. Tighten the pipe clamps.
9. If fitted, connect the connector of the fuel
temperature sensor (1) on the fuel fine filter
head and the connector of the fuel pump
control solenoid valve (2).
10. Fit the fuel pipes to the high-pressure pump.
11. Bleed the fuel system. See "Inspection and
adjustment".
