7) Remove tappets (2) with shims (1).
INSPECTION
Cam Wear
Using a micrometer, measure cam height “a”. If measured height
is below its limit, replace camshaft.
Cam height “a” of camshaft
Camshaft Runout
Set camshaft between two “V” blocks, and measure its runout by
using a dial gauge.
If measured runout exceeds below limit, replace camshaft.
Camshaft runout limit
: 0.10 mm (0.0039 in.)
Camshaft Journal Wear
Check camshaft journals and camshaft housings for pitting,
scratches, wear or damage.
If any malcondition is found, replace camshaft or cylinder head
with housing. Never replace cylinder head without replacing hous-
ings.
Check clearance by using gaging plastic. Checking procedure is
as follows.
1) Clean housings and camshaft journals.
2) Remove all tappets with shims.
3) Install camshafts to cylinder head.
4) Place a piece of gaging plastic to full width of journal of cam-
shaft (parallel to camshaft).
5) Install camshaft housing.

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.)

7) Install valve spring and spring retainer.
Each valve spring has top end (large-pitch end (1)) and bot-
tom end (small-pitch end (2)). Be sure to position spring in
place with its bottom end (small-pitch end) facing the bottom
(valve spring seat side).
8) Using special tools (Valve lifter), compress valve spring and
fit two valve cotters (1) into groove in valve stem.

inder head.
INSTALLATION
1) Clean mating surface of cylinder head and cylinder block.
Remove oil, old gasket and dust from mating surface.
2) Install knock pins (1) to cylinder block.
3) Install new cylinder head gasket (2) to cylinder block.
“TOP” mark provided on gasket comes to crankshaft pulley
side, facing up (toward cylinder head side).
4) Make sure that oil jet (venturi plug) (1) is installed and if it is,
that it is not clogged.

NOTE:
When compressing the valve spring, be carefully to free
from damage in inside face of tappet installing hole.

5) Install cylinder head to cylinder block.
Apply engine oil to new cylinder head bolts and tighten them
gradually as follows.
a) Tighten cylinder head bolts (“1” – “10”) to 20 N·m (2.0 kg-m,
14.5 lb-ft) according to numerical order as shown by using
a 12 corner socket wrenches.
b) In the same manner as in Step a), tighten them to 40 N·m
(4.0 kg-m, 29.0 lb-ft).
c) Turn all bolts 60° according to numerical order in figure.
d) Repeat Step c).

inder bore, point front mark on piston head to crankshaft pul-
ley side.
4) Install piston and connecting rod assembly into cylinder
bore. Use special tool (Piston ring compressor) to compress
rings. Guide connecting rod into place on crankshaft.
