(b) Secure the exhaust camshaft sub gear to drive gear
with a service bolt.
Recommended service bolt:
Thread diameter6 mm
Thread pitch 1.0 mm
Bolt length 16±20 m m (0.63±0.79 in.)
HINT: When removing the camshaft, make sure that
the torsional spring force of the sub gear has been
eliminated by the above operation. 35. REMOVE CAMSHAFTS
NOTICE: Since the thrust clearance of the camshaft is
small, the camshaft must be kept level while it is being
removed. If the camshaft is not kept level, the portion of
the cylinder 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.
A. Remove exhaust camshaft
(a) Set the knock pin of the intake camshaft at 10±455
BTDC of camshaft position.
HINT: The above angle allows No.2 and No.4 cylinder
cam lobes of the exhaust camshaft to push their valve
lifters evenly.HINT: Arrange the grommets in correct order, so that
they can be reinstalled into their original positions.
This minimizes any possibility of oil leakage due to
reuse of grommets.
34. REMOVE HIGH ± TENSION CORDS CLAMP AND
PCV VALVE

(e) Alternately loosen and remove the 2 bolts on the No.
2 bearing cap.
HINT:
wAs the 2 No.2 bearing cap bolts are loosened, make
sure that the camshaft is lifted out straight and level,
after breaking adhesion on the front bearing cap.
wIf the camshaft is not being lifted out straight and
level, retighten the 2 No.2 bearing cap bolts. Reverse
the order of above steps from (e) to (a) and reset the
knock pin of the intake camshaft at 80±115*6TDC,
and repeat steps from (b) to (e) once again.
NOTICE: Do not pry on or attempt to force the camshaft
with a tool or other object.
(f) Remove the No.2 bearing cap and camshaft. (c) Uniformly loosen and remove the6 bolts on the No.1,
No.3 and No.4 bearing caps in several passes in the
sequence shown.
NOTICE: Do not remove the No.2 bearing cap bolts at this
stage.
(d) Remove the No. 1, No.3 and No.4 bearing caps.
36. DISASSEMBLE EXHAUST CAMSHAFT
(a) Mount the hexagon wrench head portion of the cam±
shaft in a vise.
NOTICE: Be careful not to damage the camshaft.
(b) Remove the 2 bolts, front bearing cap and oil seal.

CYLINDER HEAD COMPONENTS
INSPECTION, CLEANING AND REPAIR
1. CLEAN TOP SURFACES OF PISTONS AND
CYLINDER BLOCK
(a) Turn the crankshaft, and bring each piston to top dead
center (TDC). Using a gasket scraper, remove all the
carbon from the piston top surface.
(b) Using a gasket scraper, remove all the gasket material
from the cylinder block surface.
(c) Using compressed air, blow carbon and oil from the
bolt holes.
CAUTION: Protect your eyes when using high pressure
compressed air.
2. CLEAN CYLINDER HEAD
A. Remove gasket material
Using a gasket scraper, remove all the gasket material
from the cylinder block contact surface.
NOTICE: Be careful not to scratch the cylinder block
contact surface.
B. Clean combustion chambers
Using a wire brush, remove all the carbon from the
combustion chambers.
NOTICE: Be careful not to scratch the cylinder block
contact surface.
(c) Using needle±nose pliers, remove the oil seal.

(c) Subtract the valve stem diameter measurement from
the guide bushing inside diameter measurement.
Standard oil clearance:
Intake
0.025 ± 0.060 mm (0.0010 ± 0.0024 in.)
Exhaust
0.030 ± 0.065 mm (0.0012 ± 0.0028 in.)
Maximum oil clearance:
Intake
0.08 mm (0.0031 in.)
Exhaust
0.10 mm (0.0039 In.)
If the clearance is greater than maximum, replace the
valve and guide bushing. (b) Using a micrometer, measure the diameter of the
valve stem.
Valve stem diameter:
Intake
5.970 ± 5.985 mm (0.2350 ± 0.2356 in.)
Exhaust
5.965 ± 5.980 mm (0.2348 ± 0.2354 In.) 5. INSPECT VALVE STEMS AND GUIDE BUSHINGS

the guide bushing.
Bushing inside diameter:
6.010 ±6.030 mm (0.2366 ± 0.2374 in.) 4. CLEAN VALVES
(a) Using a gasket scraper, chip off any carbon from the
valve head.
(b) Using a wire brush, thoroughly clean the valve.
