INSTALLATION OF CYLINDER HEADS
(See page EM±75)
1. INSTALL CYLINDER HEADS
A. Place cylinder head on cylinder block
(a) Place a new cylinder head gasket in position on the
cylinder block.

HINT:
wThe cylinder head bolts are tightened in three progres±
sive steps (steps (b), (d) and (e)).
wIf any bolts is broken or deformed, replace them.
(a) Apply a light coat of engine oil on the threads and under the
heads of the cylinder head bolts.
(b) Install and uniformly tighten the cylinder head bolts in
several passes in the sequence shown.
Torque: 350 kg±cm (25 ft±lb, 34 N±m)
If any one of the bolts does not meet the torque specification,
replace the bolt.
(d) Retighten the cylinder head bolts 90° in the numerical
order shown.
(e) Retighten cylinder head bolts by an additional 90°.
(f) Check that the painted mark is now facing rearward. (c) Mark the front of the cylinder head bolt head with paint.

3. ASSEMBLE EXHAUST CAMSHAFTS
(a) Install the following parts:
(1) Camshaft gear spring
(2) Camshaft sub±gear

4. INSTALL CAMSHAFTS
NOTICE: Since the thrust clearance of the camshaft is
small, the camshaft must be held level white it is being
installed. If the camshaft is not level, the portion of the cyl-
inder 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. (d) Insert a service bolt (A) into the service hole of the cam-
shaft sub±gear.
(e) Using a screwdriver, align the holes of the camshaft
driven gear and sub±gear by turning camshaft sub-
gear clockwise, and install a service bolt (B).
NOTICE: Be careful not to damage the camshaft.
A. Install intake camshaft of R H cylinder head
(a) Apply MP grease to the thrust portion of the camshaft.
(b) Place the intake camshaft at 90° angle of timing mark
(two pointed marks) on the cylinder head.
(c) Apply seal packing to the No. 1 bearing cap as shown.
Seal packing: Part No. 08826±00080 or equivalent
(d) Install the five bearing caps in their proper locations.

(e) Apply a light coat of engine oil on the threads and under
the heads of the bearing cap bolts.
(f) Install and uniformly tighten the eight bearing cap bolts
in several passes in the sequence shown.
Torque: 16o kg±cm (12 ft±lb, 16 N±m)
(g) Remove the service bolt (6). 6. Install exhaust camshaft of RH cylinder head
(a) Apply MP grease to the thrust portion of the camshaft.
(b) Align the timing marks (two pointed marks) of the camshaft
drive and driven gears.
(c) Place the exhaust camshaft on the cylinder head. (e) Apply a light coat of engine oil on the threads and under
the heads of the bearing cap bolts.
(f) Install and uniformly tighten the ten bearing cap bolts
in several passes in the sequence shown.
Torque: 160 kg±cm (12 ft±lb, 16 N±m)
C. Install intake camshaft of LH cylinder head
(a) Apply MP grease to the thrust portion of the camshaft.
(b) Place the intake camshaft at 90° angle of timing mark
(one pointed mark) on the cylinder head. (d) Install the four bearing caps in their proper location.

D. Install exhaust camshaft of LH cylinder head
(a) Apply MP grease to the thrust portion of the camshaft.
(b) Align the timing marks (one pointed mark) of the camshaft
drive and driven gears.
(c) Place the intake camshaft on the cylinder head. (e) Apply a light coat of engine oil on the threads and under
the heads of the bearing cap bolts.
M Install and uniformly tighten the ten bearing cap
bolts in several passes in the sequence shown.
Torque: 160 kg±cm (12 ft±Ib, 16 N±m)
(c) Apply seal packing to the No. 1 bearing cap as shown.
Seal packing: Part No. 08826±00080 or equivalent
