9) Remove the belt cover No. 2 (RH).

10) Disconnect the ignition coil connector.
11) Remove the ignition coil.
12) Remove the rocker cover and gasket.
13) Loosen the intake camshaft cap bolts equally, a
little at a time in alphabetical sequence shown in
the figure.

B: INSTALLATION

1) Camshaft installation:
Apply engine oil to the cylinder head at camshaft
bearing location before installing the camshaft. In-
stall the camshaft so that each valves is close to or
in contact with “base circle” of cam lobe.

NOTE:
• When the camshafts are positioned as shown in
the figure, camshafts need to be rotated at a mini-
mum to align with the timing belt during installation.
• Camshaft (RH) need not be rotated when set at
the position shown in the figure.
Intake camshaft (LH): Rotate 80

clockwise.

Exhaust camshaft (LH): Rotate 45

counterclock-

wise.

2) Camshaft cap installation:

(1) Apply fluid packing sparingly to the cap mat-
ing surface.

NOTE:
Do not apply fluid packing excessively. Failure to
do so may cause excess packing to come out and
flow toward oil seal, resulting in oil leaks.

Fluid packing:

Part No. 004403007

THREE BOND 1215 or equivalent

(2) Apply engine oil to cap bearing surface and
install the cap on camshaft as shown by identifi-
cation mark (A).
(3) Gradually tighten the camshaft cap in at
least two stages in alphabetical sequence
shown in the figure, and then tighten to specified
torque.

Tightening torque:

T1: 10 N·m (1.0 kgf-m, 7.2 ft-lb)
T2: 20 N·m (2.0 kgf-m, 14.5 ft-lb)

(4) Similarly, tighten the cap on exhaust side.
After tightening the cap, ensure the camshaft ro-
tates only slightly while holding it at “base” circle.

Tightening torque:

T1: 10 N·m (1.0 kgf-m, 7.2 ft-lb)
T2: 20 N·m (2.0 kgf-m, 14.5 ft-lb)

4) Rocker cover installation:

(1) Install the gasket on rocker cover.
Install the peripheral gasket and ignition coil
gasket.
(2) Apply fluid packing to the indicated portion
on rocker cover.

Fluid packing:

Part No. 004403007

(3) Install the rocker cover on cylinder head.
Ensure the gasket is properly positioned during
installation.

5) Install the ignition coil.
6) Connect the ignition coil connector.

7) Similarly, install the parts on right-hand side.
8) Install the belt cover No. 2 (RH).

Tightening torque:

5 N·m (0.5 kgf-m, 3.6 ft-lb)

9) Install the tensioner bracket.

Tightening torque:

25 N·m (2.5 kgf-m, 18.1 ft-lb)

10) Install the belt cover No. 2 (LH).

Tightening torque:
