(b) Secure the exhaust camshaft sub gear to drive gear
with a service bolt.
Recommended service bolt:
Thread diameter6 mm
Thread pitch 1.0 mm
Bolt length 16±20 m m (0.63±0.79 in.)
HINT: When removing the camshaft, make sure that
the torsional spring force of the sub gear has been
eliminated by the above operation. 35. REMOVE CAMSHAFTS
NOTICE: Since the thrust clearance of the camshaft is
small, the camshaft must be kept level while it is being
removed. 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. Remove exhaust camshaft
(a) Set the knock pin of the intake camshaft at 10±455
BTDC of camshaft position.
HINT: The above angle allows No.2 and No.4 cylinder
cam lobes of the exhaust camshaft to push their valve
lifters evenly.HINT: Arrange the grommets in correct order, so that
they can be reinstalled into their original positions.
This minimizes any possibility of oil leakage due to
reuse of grommets.
34. REMOVE HIGH ± TENSION CORDS CLAMP AND
PCV VALVE

(f) Alternately loosen and remove the 2 bolts on the No.
3 bearing cap.
HINT:
wAs the 2 No.3 bearing cap bolts are loosened, make
sure that the camshaft is lifted out straight and level.
wIf the camshaft is not being lifted out straight and
level, retighten the 2 No.3 bearing cap bolts. Then
reverse the order of above steps from (f) to (a) and
reset the knock pin of the intake camshaft at 10±45
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.
(g) Remove the No.3 bearing cap and exhaust camshaft.(d) Uniformly loosen and remove the6 bolts on the No. 1,
No.2 and No.4 bearing caps in several passes in the
sequence shown.
NOTICE: Do not remove the No.3 bearing cap bolts at this
stage.
(e) Remove the No. 1, No.2 and No.4 bearing caps.
B. Remove intake camshaft
(a) Set the knock pin of the intake camshaft at 80±115
BTDC of camshaft angle.
HINT: The above angle allows the No.1 and No.3
cylinder cam lobes of intake camshaft to push their
valve lifters evenly.(c) Remove the 2 bolts and rear bearing cap.

(e) Alternately loosen and remove the 2 bolts on the No.
2 bearing cap.
HINT:
wAs the 2 No.2 bearing cap bolts are loosened, make
sure that the camshaft is lifted out straight and level,
after breaking adhesion on the front bearing cap.
wIf the camshaft is not being lifted out straight and
level, retighten the 2 No.2 bearing cap bolts. Reverse
the order of above steps from (e) to (a) and reset the
knock pin of the intake camshaft at 80±115*6TDC,
and repeat steps from (b) to (e) once again.
NOTICE: Do not pry on or attempt to force the camshaft
with a tool or other object.
(f) Remove the No.2 bearing cap and camshaft. (c) Uniformly loosen and remove the6 bolts on the No.1,
No.3 and No.4 bearing caps in several passes in the
sequence shown.
NOTICE: Do not remove the No.2 bearing cap bolts at this
stage.
(d) Remove the No. 1, No.3 and No.4 bearing caps.
36. DISASSEMBLE EXHAUST CAMSHAFT
(a) Mount the hexagon wrench head portion of the cam±
shaft in a vise.

NOTICE: Be careful not to damage the contact surfaces
of the cylinder head and cylinder block.
