1. Temporarily tighten sensor body fixing bolts as follows.
+Gradually move the sensor body clockwise and stop it when ªCLSD THL/P SWº signal switches from ªOFFº to
ªONº, then temporarily tighten sensor body fixing bolts.

reverse order of the numbers in the figure.
+When the flare nuts are loosened, hold the head of hexagonal
retaining bolts (head inside) using a wrench.
Installation
NJEC0618S03021. Tighten the flare nuts and mounting bolts in the numerical
order shown in the figure.
+When the flare nuts are tightened, hold the head of the hex-
agonal retaining bolts (head inside) using a wrench.
2. To prevent interference with the rocker cover, place the spill
gasket joint within the range shown by the arrow, then tighten
the mounting bolts. (Be especially careful about No. 2 and 4
cylinders.)
+After the spill tube is installed, check the airtightness of
the spill tube.
+After the bolts are tightened, the joint of the spill tube gasket
might be broken. However, this will not affect function.

CAUTION:
Do not disassemble the high-pressure injection nozzle.
Installation
NJEC0618S04021. Insert the nozzle gasket to the cylinder head hole.
2. Attach the O-ring to the mounting groove of the nozzle side,

2. Disconnect the fuel hoses from the fuel injection pump.
3. Disconnect the harness connector from the fuel injection
pump.
+Disconnect the connector by pulling the connector stopper
fully.
+When the stopper is fully pulled, the connector will be discon-
nected together. For installation, push the connector half way
first, then press the stopper until it locks, so that the connec-
tor is connected together.
4. Remove the fuel injection pump rear bracket.

5. Remove the front chain case.
+Move the power steering fluid reservoir tank from the bracket.
+Loosen and remove the mounting bolts in the reverse order of
the numbers shown in the figure.
+As for bolts 6, 10, and 11, remove with rubber washer because
there is not enough space for removing only the bolts.
CAUTION:
To prevent foreign objects from getting in the engine, cover
the opening during the removal of the front chain case.

6. Adjust the No. 1 cylinder to the top dead center position.
+Turn the crankshaft pulley clockwise, then align the alignment
mark (punched mark) of the camshaft sprocket to the position
shown in the figure.
+There is no indicator on the crankshaft pulley.
+It is not necessary to mark the secondary timing chain for
removal because it can be matched by the link color for instal-
lation. However, the alignment mark on the fuel injection pump
sprocket is difficult to see; mark it if necessary.
