Installing:
– Check plunger -1- for damage, renew if necessary. Insert oiled
plunger along guide -2- correctly into cylinder head.
– Slowly turn engine by vibration damper in engine's direction of
rotation. When doing this, press plunger in
-direction of arrow- until it has reached lowest point in cylinder
head.
– Renew high-pressure pump O-ring and coat slightly with clean
engine oil.
– Install high-pressure pump and tighten securing bolts
-arrows-.
– Tighten union for high-pressure pipe and low-pressure pipe at
high-pressure pump.
High-pressure pipe union: 40 Nm
Low-pressure line union: 28 Nm.
Caution
♦ The low-pressure hose must always be renewed because
when pulling off, it will be damaged by the corrugated pipe
connection.
♦ Make sure low-pressure hose and high-pressure hose do
not touch each other after bolts have been tightened. En‐
sure there is sufficient »clearance« between them.
– Install new low-pressure hose -A-. When doing this, take in‐
stallation markings and position of spring clamps -arrows- into
consideration.
– Install high-pressure pipe but only tighten bolts hand-tight.
