(e) Align the camshaft knock pin with the knock pin groove of
the timing tube, and push the timing tube by hand until you
it touches the bottom.
(f) Using a 10 mm hexagon wrench, install the bolt.
Torque: 78 N´m (790 kgf´cm, 58 ft´lbf)
(g) Install the seal washer and screw plug.
Torque: 15 N´m (150 kgf´cm, 11 ft´lbf)
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

(4) Install the camshaft housing plug to the cylinder
head as shown in the illustration.
(5) Install the strainer to the cylinder head.
NOTICE:
Be careful of the installation direction.
(6) Apply seal packing to the front bearing cap.

Remove any old packing material (FIPG) and
be careful not to drop any oil on the contact
surfaces of the bearing cap and cylinder
head.
Using a razor blade and gasket scraper, re-
move all the old packing material (FIPG) from
the gasket surfaces and groove.
Thoroughly clean all components to remove
all the loose material.
Using a non±residue solvent, clean both
sealing surfaces.

Apply seal packing to the bearing cap as
shown in the illustration.
Install a nozzle that has been cut to a 1.5 mm
(0.059 in.) opening.
Parts must be assembled within 5 minutes of
application. Otherwise the material must be
removed and reapplied.
Immediately remove the nozzle from the tube
and reinstall cap.
Seal packing: Part No. 08826±00080 or equivalent
NOTICE:
Do not apply seal packing to the front bearing cap grooves.
(7) Install the front bearing cap.
HINT:
Installing the front bearing cap will determine the thrust portion
of the camshaft.
(8) Install the other bearing caps in the sequence
shown with the arrow mark facing forward.
