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.

(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)
