16. SET NO.1 CYLINDER TO TDC/COMPRESSION
(a) Turn the crankshaft pulley and align its groove with timing
mark º0º of the No.1 timing belt cover.
(b) Check that the timing marks of the camshaft timing pul-
leys and timing belt rear plates are aligned.
If not, turn the crankshaft 1 revolution (360°).
(c) Turn the crankshaft pulley approx. 50° clockwise, and
align the timing mark of the crankshaft pulley with the cen-
ters of the crankshaft pulley bolt and the No.2 timing belt
idler pulley bolt.
NOTICE:
If the timing belt is disengaged, having the crankshaft
pulley at the wrong angle can cause the piston head and
valve head to come into contact with each other when you
remove the camshaft timing pulley (step 15), causing dam-
age. So always set the crankshaft pulley at the correct
angle.
(d) Remove the crankshaft pulley bolt.
NOTICE:
Do not turn the crankshaft pulley.
17. REMOVE TIMING BELT TENSIONER
HINT:

When re±using the timing belt:
If the installation marks have disappeared, before remove
the timing belt, place 2 new installation marks on the tim-
ing belt to match the timing marks of the camshaft timing
pulleys.

8. INSTALL CAMSHAFTS
NOTICE:
Since the thrust clearance of the camshaft is small, the
camshaft must be kept 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, caus-
ing the camshaft to seize or break. To avoid this, the follow-
ing steps should be carried out.
(a) Set the crankshaft pulley position.
Turn the pulley clockwise or counterclockwise, and align
the timing mark of the crankshaft pulley with the centers
of the crankshaft pulley bolt and idler pulley bolt.
NOTICE:
Having the crankshaft pulley at the wrong angle can cause
the piston head and valve head to come into contact with
each other when you install the camshaft, causing dam-
age. So always set the crankshaft pulley at the correct
angle.
(b) Install the LH camshafts.
(1) Apply MP grease to the thrust portion of the intake
and exhaust camshafts.
(2) Align the timing marks (2±dot mark) of the camshaft
drive and driven main gears, and place the intake
and exhaust camshafts.
(3) Apply seal packing to the camshaft housing plug.

Remove the old packing material (FIPG).

Apply seal packing to the housing plug.
Seal packing: Part No. 08826±00080 or equivalent
