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.
CAUTION:
When the camshafts are positioned as shown
in the figure, camshafts need to be rotated at a
minimum to align with the timing belt during in-
stallation.
Right-hand camshaft need not be rotated
when set at the position shown
in
the figure.
Left-hand intake camshaft: Rotate
80”
clock-
wise.
Left-hand exhaust camshaft: Rotate
45”
coun-
terclockwise.

Camshaft cap installation:
(1)
Apply fluid packing sparingly to the cap mat-
ing surface.
CAUTION:
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:
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 cap in at least two
stages in alphabetical sequence shown in the
figure, and then tighten to specified torque.

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