(b) Install the cylinder head bolts.
HINT:
The cylinder head bolts are tightened in 2 progressive
steps (steps (b) and (d)).
If any cylinder head bolt is broken or deformed, replace
it.
(1) Apply a light coat of engine oil on the threads and
under the heads of the cylinder head bolts.
(2) Install and uniformly tighten the 10 cylinder head
bolts and plate washers, in several passes, in the
sequence shown.
Torque: 49 N·m (500 kgf·cm, 36 ft·lbf)
If any one of the cylinder head bolts does not meet the torque
specification, replace the cylinder head bolt.
(3) Mark the front of the cylinder head bolt head with
paint.
(4) Retighten the cylinder head bolts 90° in the se-
quence shown above.
(5) Check that the painted mark is now at a 90° angle
to front.
7. INSTALL SPARK PLUG TUBES
(a) Clean the cylinder head tube holes of any residual adhe-
sive, oil or foreign particles. Remove any oil with kerosene
or gasoline.
(b) Screw the threads of the spark plug tube coated with
adhesive into the cylinder head.
(c) Using the spark plug tube nut and a 30 mm socket
wrench, tighten the spark plug tubes.
Torque: 39 N·m (400 kgf·cm, 29 ft·lbf)
8. ASSEMBLE EXHAUST CAMSHAFT
(a) Mount the hexagon wrench head portion of the camshaft
in a vise.

(c) Using snap ring pliers, install the snap ring.
(d) Insert a service bolt A into the service hole of the camshaft
sub gear.
(e) Using a screwdriver, align the holes of the camshaft drive
gear and sub gear by turning camshaft sub gear clock-
wise, and install a service bolt B.
NOTICE:
Be careful not to damage the camshaft.
(f) Align the gear teeth of the drive gear and sub gear, and
tighten the service bolt B.
9. 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) Install the intake camshaft.
(1) Apply MP grease to the thrust portion of the cam-
shaft.
(2) Place the intake camshaft at 80 − 11 5° BTDC of
camshaft angle on the cylinder head.
HINT:
The above angle arrows the No. 1 and No. 3 cylinder cam lobes
of the intake camshaft to push their valve lifters evenly.
(3) Apply MP grease to a new oil seal lip.
(4) Install the oil seal as far as the deepest part of the
cylinder head.
(5) Apply seal packing to the No. 1 bearing cap as
shown.
Seal packing: Part No. 08826−00080 or equivalent

(6) Install the bearing caps in their proper locations.
(7) Apply a light coat of engine oil on the threads and
under the heads of the bearing cap bolts.
(8) Install and uniformly tighten the 10 bearing cap
bolts, in several passes, in the sequence shown.
Torque: 19 N·m (190 kgf·cm, 14 ft·lbf)
(b) Install the exhaust camshaft.
(1) Set the knock pin of the intake camshaft at 10 − 45°
BTDC of camshaft angle.
HINT:
The above angle allows the No. 2 and No. 4 cylinder cam lobes
of the exhaust camshaft to push their valve lifters evenly.
(2) Apply MP grease to the thrust portion of the cam-
shaft.
(3) Engage the exhaust camshaft gear to the intake
camshaft gear by matching the timing marks on
each gear.
(4) Roll down the exhaust camshaft onto the bearing
journals while engaging gears with each other.
NOTICE:
There are also assembly reference marks on each gear as
shown in the illustration. Do not use these marks.
(5) Turn the intake camshaft clockwise or counterclock-
wise a little until the exhaust camshaft sits in the
bearing journals evenly without rocking the cam-
shaft on the bearing journals.
NOTICE:
It is very important to replace the camshaft in the bearing
journals evenly while tightening bearing caps in the subse-
quent steps.
