(g) Inspect the camshaft gear backlash.
(1) Install the camshafts without installing the exhaust
cam sub±gear. (See page EM±53)
(2) Using a dial indicator, measure the backlash.
Standard backlash:
0.020 ± 0.200 mm (0.0008 ± 0.0079 in.)
Maximum backlash: 0.30 mm (0.0188 in.)
If the backlash is greater then maximum, replace the cam-
shafts.
11. INSPECT VALVE LIFTERS AND LIFTER BORES
(a) Using a caliper gauge, measure the lifter bore diameter
of the cylinder head.
Lifter bore diameter:
31.000 ± 31.018 mm (1.2205 ± 1.2212 in.)
(b) Using a micrometer, measure the lifter diameter.
Lifter diameter:
30.966 ± 30.976 mm (1.2191 ± 1.2195 in.)
(c) Subtract the lifter diameter measurement from the lifter
bore diameter measurement.
Standard oil clearance:
0.024 ± 0.052 mm (0.0009 ± 0.0020 in.)
Maximum oil clearance: 0.07 mm (0.0028 in.)
If the oil clearance is greater than maximum, replace the lifter.
If necessary, replace the cylinder head.
12. INSPECT INTAKE MANIFOLD
Using a precision straight edge and feeler gauge, measure the
surface contacting the cylinder head for warpage.
Maximum warpage: 0.30 mm (0.0118 in.)
If warpage is greater than maximum, replace the manifold.
13. INSPECT EXHAUST MANIFOLD
Using a precision straight edge and feeler gauge, measure the
surface contacting the cylinder head for warpage.
Maximum warpage: 0.30 mm (0.0118 in.)

INSTALLATION
1. PLACE CYLINDER HEAD ON CYLINDER BLOCK
(a) Place a new cylinder head gasket on the cylinder block.
NOTICE:
Be careful of the installation direction.
(b) Place the cylinder head on the cylinder head gasket.
2. INSTALL 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.
(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 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.
(c) Mark the front of the cylinder head bolt head with paint.
(d) Retighten the cylinder head bolts 90° in the numerical or-
der shown.
(e) Check that the painted mark is now at a 90° angle to the
front.
(f) Install the 2 bolts holding the water bypass pipe to the cyl-
inder head.
Torque: 19 N´m (195 kgf´cm, 14 ft´lbf)
(g) Connect the camshaft position sensor connector.
3. 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: 49 N´m (500 kgf´cm, 36 ft´lbf)

4. ASSEMBLE EXHAUST CAMSHAFT
(a) Mount the camshaft in a vise.
NOTICE:
Be careful not to damage the camshaft.
(b) Install the camshaft gear spring, camshaft sub±gear and
wave washer.
HINT:
Align the pins on the gears with the spring ends.
(c) Using snap ring pliers, install the snap ring.
(d) Using SST, align the holes of the camshaft drive gear and
sub±gear by turning camshaft sub±gear clockwise, and
install a service bolt.
SST 09960±10010 (09962±01000, 09963±00500)
(e) Align the gear teeth of the drive gear and sub±gear, and
tighten the service bolt.
5. 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 ± 115° BTDC of
camshaft angle on the cylinder head.

of the intake camshaft to push their valve lifters evenly.
(3) Apply seal packing to the No.1 bearing cap as
shown.
Seal packing: Part No. 08826±00080 or equivalent
(4) Install the bearing caps in their proper locations.

under the heads of the bearing cap bolts.
(6) 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.
(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.
