[*2]
q How to install high-pressure pipe (10)
1. Tighten the sleeve nut with the fingers.
2. Check that the high-pressure pipe is installed
correctly and tighten the sleeve nut to the fol-
lowing torque.

a The boot is installed so that fuel will not
spout over the hot parts of the engine and
catch fire when it leaks for some reason.
[*3]
a If too much grease is applied to O-ring (13), it
will ooze out. Accordingly, do not apply grease

q Precautions for installing inlet connector
1) When replacing the fuel injector assembly
with new one, be sure to replace inlet con-
nector, too.
2) Check the inlet connector visually. If it has
any of the following faults, replace it.
1] There is a bur or a worn part at front
end (a) or rear end (b) of the inlet
connector.
2] There is foreign matter in the edge fil-
ter at rear end (c) of the inlet connec-
tor.
3] The O-ring at upper part (d) of the
inlet connector is cracked or deterio-
rated.
3) Check the inlet connector visually. If it has
any of the following faults, replace it and
fuel injector assembly together.
q There is a worn part or an uneven
seat contact mark on sealing face (e)
at the front end of the inlet connector.
a If high-pressure fuel leaks
through the inlet connector, the
seal face has fine streaks or
cracks.
2. Crosshead and rocker arm assembly
1) Install the crosshead and rocker arm.
a The shapes of holes (a) and (b) of
each crosshead are different. Accord-
ingly, when reusing the crossheads,
install each of them to the same
intake/exhaust valve in the same
direction as it has been installed.
2) Check that the ball of adjustment screw
(19) is set in the push rod socket securely
and then tighten mounting bolts (30).
3 Rocker arm mounting bolt (30):
36 ± 5 Nm {3.7 ± 0.5 kgm}
3) Adjust the valve clearance. For details,
see Testing and adjusting, "Adjusting
valve clearance".
