INSTALLATION
1. PLACE CYLINDER HEAD ON CYLINDER BLOCK
(a) Place 2 new cylinder head gaskets in position on the cylin-
der block.
NOTICE:
Be careful of the installation direction.
(b) Place the 2 cylinder heads in position on the cylinder head
gaskets.
2. INSTALL 12 POINTED HEAD CYLINDER HEAD BOLTS
HINT:
The cylinder head bolts are tightened in 2 progressive
steps (steps (c) and (e)).
If any bolt is broken or deformed, replace it.
(a) Apply a light coat of engine oil on the threads and under
the heads of the cylinder head bolts.
(b) Install the plate washer to the cylinder head bolt.
(c) Install and uniformly tighten the cylinder head bolts on
each cylinder head, in several passes, in the sequence
shown, then repeat for the other side, as shown.
Torque: 54 N´m (550 kgf´cm, 40 ft´lbf)
If any of the cylinder head bolts does not meet the torque speci-
fication, replace the cylinder head bolt.
(d) Mark the front of the cylinder head bolt head with paint.
(e) Retighten the cylinder head bolts by 90° in the numerical
order shown.
(f) Check that the painted mark is now at a 90° angle to the
front.

bolt on each cylinder head, then repeat for the other side,
as shown.
Torque: 18.5 N´m (185 kgf´cm, 13 ft´lbf)
4. ASSEMBLE EXHAUST CAMSHAFTS
(a) Mount the hexagonal wrench head portion of the cam-
shaft in a vise.

sub±gear by turning camshaft sub±gear counterclock-
wise, and temporarily install a service bolt.

(f) Align the gear teeth of the main gear and sub±gear, and
tighten the service bolt.
5. INSTALL CAMSHAFTS OF RH CYLINDER HEAD
NOTICE:
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 level, the portion of the cylinder head re-
ceiving 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 the exhaust camshaft.
(1) Apply new engine oil to the thrust portion and jour-
nal of the camshaft.
(2) Place the exhaust camshaft at 90° angle of timing
mark (2 dot marks) on the cylinder head.
(3) Apply MP grease to a new oil seal lip.
(4) Install the oil seal to the camshaft.
(5) Remove any old packing (FIPG) material.
(6) Apply seal packing to the No.1 bearing cap as
shown.
