Wear of tappet and shim
Check tappet and shim for pitting, scratches or damage.
If any malcondition is found, replace.
Measure cylinder head bore and tappet outside diameter to deter-
mine cylinder head-to-tappet clearance. If clearance exceeds
limit, replace tappet or cylinder head.
Cylinder head to tappet clearance
Standard : 0.025 – 0.066 mm (0.0010 – 0.0026 in.)
Limit : 0.15 mm (0.0059 in.)
Tappet outside diameter [A]
Standard : 30.959 – 30.975 mm (1.2189 – 1.2195 in.)

INSTALLATION
1) Install tappets and shims to cylinder head.
Apply engine oil around tappet and then install it to cylinder
head.
2) Install camshafts (1).
Apply engine oil to sliding surface of each camshaft and camshaft
journal then install them as shown in figure.
NOTE:
When installing shim, make sure to direct shim No. side
toward tappet.
NOTE:
Before installing camshafts, turn crankshaft until key
position faces upward. Refer to “TIMING CHAIN AND
CHAIN TENSIONER”.

Embossed marks are provided on each camshaft housing,
indicating position and direction for installation. Install hous-
ings as indicated by these marks.
5) After applying engine oil to housing bolts, tighten them tem-
porarily first. Then tighten them by the following numerical

ure by using a 12 corner socket wrenches and remove them.
17) Check all around cylinder head for any other parts required
to be removed or disconnected and remove or disconnect
whatever necessary.
18) Remove exhaust manifold, if necessary, referring to
“EXHAUST MANIFOLD”.

INSPECTION
Valve Guides
Using a micrometer and bore gauge, take diameter readings on
valve stems and guides to check stem-to-guide clearance. Be
sure to take reading at more than one place along the length of
each stem and guide.
If clearance exceeds limit, replace valve and valve guide.
Valve stem-to-guide clearance
Valve stem diameter [A]
Valve guide bore [B] standard
In and Ex : 6.000 – 6.012 mm (0.2362 – 0.2367 in.) for 69G
type valve
In and Ex : 5.485 – 5.510 mm (0.2159 – 0.2169 in.) for 54G
type valve
If bore gauge is not available, check end deflection of valve stem
with a dial gauge instead.
Move stem end in directions (1) and (2) to measure end deflec-
tion.
If deflection exceeds its limit, replace valve stem and valve guide.

Valves
Remove all carbon from valves.
Inspect each valve for wear, burn or distortion at its face and
stem end, as necessary, replace it.
Measure thickness “a” of valve head. If measured thickness
exceeds limit, replace valve.
Valve head thickness (In and Ex)
Standard : 1.22 – 1.55 mm (0.048 – 0.061 in.)
Limit : 0.9 mm (0.035 in.)
Inspect valve stem end face for pitting and wear. If pitting or
wear is found there, valve stem end may be resurfaced, but
not too much to grind off its chamber. When it is worn out too
much that its chamber is gone, replace valve.
Check each valve for radial runout with a dial gauge and “V”
block. To check runout, rotate valve slowly. If runout exceeds
its limit, replace valve.
Limit on valve head radial runout
: 0.08 mm (0.003 in.)
Seating contact width:
Create contact pattern on each valve in the usual manner,
i.e. by giving uniform coat of marking compound to valve
seat and by rotatingly tapping seat with valve head. Valve
lapper (tool used in valve lapping) must be used.
Pattern produced on seating face of valve must be a continu-
ous ring without any break, and the width of pattern must be
within specified range.
Standard seating width “a” revealed by contact pattern on
valve face
In and Ex : 1.1 - 1.3 mm (0.0433 - 0.0512 in.)

ENGINE MECHANICAL (M13 ENGINE) 6A1-51
Check cylinder head for cracks on intake and exhaust ports,
combustion chambers, and head surface.
Using a straightedge and thickness gauge, check flatness of
gasketed surface at a total of 2 locations. If distortion limit,
given below, is exceeded, correct gasketed surface with a
surface plate and abrasive paper of about #400 (Waterproof
silicon carbide abrasive paper): place abrasive paper on and
over surface plate, and rub gasketed surface against paper
to grind off high spots. Should this fail to reduce thickness
gauge readings to within limit, replace cylinder head.
Leakage of combustion gases from this gasketed joint is
often due to warped gasketed surface: such leakage results
in reduced power output.
Limit of distortion for cylinder head surface on piston side
: 0.03 mm (0.001 in.)
Distortion of manifold seating faces:
Check seating faces of cylinder head for manifolds, using a
straightedge and thickness gauge, in order to determine
whether these faces should be corrected or cylinder head
replaced.
Limit of distortion for cylinder head surface on intake and
exhaust manifold
: 0.05 mm (0.002 in.)

Valve Springs
Referring to data given below, check to be sure that each
spring is in sound condition, free of any evidence of break-
age or weakening. Remember, weakened valve springs can
cause chatter, not to mention possibility of reducing power
output due to gas leakage caused by decreased seating
pressure.
Valve spring free length for engine equipped with 69G
type valve
Standard : 43.00 mm (1.693 in.)
Limit : 42.00 mm (1.652 in.)
Valve spring free length for engine equipped with 54G
type valve
Standard : 36.83 mm (1.450 in.)
Limit : 35.83 mm (1.410 in.)
Valve spring preload for engine equipped with 69G type
valve
Standard : 110 – 126 N (11.2 – 12.8 kg) for 39.50 mm
(24.7 – 28.2 lb/1.555 in.)
Limit : 105 N (10.7 kg) for 39.5 mm (23.6 lb/1.555 in.)
Valve spring preload for engine equipped with 54G type
valve

Limit : 102 N (10.4 kg) for 31.50 mm (22.9 lb/1.240 in.)
Spring skewness:
Use a square and surface plate to check each spring for
skewness in terms of clearance between end of valve spring
and square. Valve springs found to exhibit a larger clearance
than limit given below must be replaced.
Valve spring skewness
Limit : 2.0 mm (0.079 in.) for engine equipped with 69G
