(c) Remove the camshafts.
19. INSPECT CAMSHAFT GEAR BACKLASH
(a) Install the camshafts without installing the exhaust cam
sub±gear. (See page EM±57)
(b) 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.
(c) Remove the camshafts.
20. INSPECT CAMSHAFT GEAR SPRING
Using vernier calipers, measure the free distance between the
spring ends.
Free distance: 18.2 ± 18.8 mm (0.712 ± 0.740 in.)
If the free distance is not as specified, replace the gear spring.
21. 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 ± 0.050 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.

REASSEMBLY
HINT:

Thoroughly clean all parts to be assembled.

Before installing the parts, apply new engine oil to all slid-
ing and rotating surfaces.

Replace all gaskets and oil seals with new ones.
1. INSTALL SPARK PLUG TUBES
HINT:
When using a new cylinder head, spark plug tubes must be
installed.
(a) Apply adhesive to the end of the spark plug tube.
Adhesive:
Part No. 08833±00070, THREE BOND 1324
or equivalent
(b) Using a press, press in a new spark plug tube until there
is 42.4 ± 43.4 mm (1.669 ± 1.709 in.) protruding from the
camshaft bearing cap installation surface of the cylinder
head.
NOTICE:
Avoid pressing a new spark plug tube in too far by measur-
ing the amount of the protrusion while pressing.
2. INSTALL PCV PIPES
HINT:
When using a new cylinder head, PCV pipe must be installed.
Using a wooden block and hammer, tap in a new PCV pipe until
its top side is flush with the cylinder head edge.
NOTICE:
Be careful not to damage the cylinder head edge.
3. INSTALL VALVES
(a) Using SST, push in a new oil seal.

3. INSTALL RECESSED HEAD CYLINDER HEAD BOLTS
(a) Apply a light coat of engine oil on the threads and under
the heads of the cylinder head bolts.
(b) Using an 8 mm hexagon wrench, install the cylinder head
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.
NOTICE:
Be careful not to damage the camshaft.
(b) Install the camshaft gear spring (1) and camshaft sub±
gear (2).
HINT:
Attach the pins on the gears to the gear spring ends.
(c) Install the wave washer (3).
(d) Using snap ring pliers, install the snap ring.

(e) Using SST, align the holes of the camshaft main gear and
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.
