(f) Alternately loosen and remove No. 2 bearing cap bolts 9
and 10.
HINT:
wAs bearing cap bolts 9 and 10 are loosened, check that the
camshaft is being lifted out straight and level, after breaking
adhesion on the front bearing cap.
wIf the camshaft is not being lifted out straight and level, re-
tighten bearing cap bolts 9 and 10. Reverse the order of
above steps from (f) to (a) and reset the knock pin of the in-
take camshaft at 80 ± 115° BTDC, and repeat steps from (b)
to (f) once again.
NOTICE: Do not pry on or attempt to force the camshaft
with a tool or other object.

.
(d) Insert a service bolt (A) into the service hole of the camshaft
sub±gear.

gear and sub±gear by turning camshaft sub±gear clock-
wise, and install a service bolt (B).
NOTICE: Be careful not damage the camshaft.
4. INSTALL CAMSHAFTS
HINT: Since the thrust clearance of the camshaft is small,
the camshaft must be held level while it is being installed.
If the camshaft is not kept level, the portion of the cylinder
head receiving the shaft thrust may crack or be damaged,
causing the camshaft to seize or break. To avoid this, the
following steps should be carried out.
A. Install intake camshaft
(a) Apply MP grease to the thrust portion of the camshaft.
(b) Place the intake camshaft at 80° BTDC of camshaft angle
on the cylinder head. 2. INSTALL SPARK PLUG TUBES

foreign particles. Remove any oil with kerosene or gasoline.
