B2M0764A
1) Camshaft installation
Apply engine oil to cylinder head at camshaft bearing loca-
tion before installing camshaft. Install camshaft so that
rocker arm is close to or in contact with“base circle”of cam
lobe.
CAUTION:
When camshafts are positioned as shown in figure,
camshafts need to be rotated at a minimum to align
with timing belt during installation.
Right-hand camshaft need not be rotated when set
at position shown in figure.
Left-hand intake camshaft: Rotate 80°clockwise.
Left-hand exhaust camshaft: Rotate 45°counter-clock-
wise.
G2M0752
2) Camshaft cap installation
(1) Apply fluid packing sparingly to cap mating surface.
CAUTION:
Do not apply fluid packing excessively. Failure to do so
may cause excess packing to come out and flow
toward oil seal, resulting in oil leaks.
Fluid packing:
THREE BOND 1215 or equivalent
G2M0753
(2) Apply engine oil to cap bearing surface and install
cap on camshaft as shown by identification mark.
(3) Gradually tighten cap in at least two stages in the
numerical order shown in figure, and then tighten to
specified torque.
(4) Similarly, tighten cap on exhaust side.
After tightening cap, ensure camshaft rotates only
slightly while holding it at“base”circle.
G2M0754
3) Camshaft oil seal installation
Apply grease to new oil seal lips and press onto front end
of camshaft by using ST1 and ST2.
CAUTION:
Use a new oil seal.

2) If the clearance between valve guide and stem exceeds
the specification, replace guide as follows:
(1) Place cylinder head on ST1 with the combustion
chamber upward so that valve guides enter the holes
in ST1.
(2) Insert ST2 into valve guide and press it down to
remove valve guide.

(4) Before installing new valve guide, make sure that
neither scratches nor damages exist on the inside sur-
face of the valve guide holes in cylinder head.
(5) Put new valve guide, coated with sufficient oil, in
cylinder, and insert ST1 into valve guide. Press in until
the valve guide upper end is flush with the upper sur-
face of ST2.

(6) Check the valve guide protrusion.
Valve guide protrusion: L
12.0—12.4 mm (0.472—0.488 in)
(7) Ream the inside of valve guide with ST. Gently
rotate the reamer clockwise while pressing it lightly into
valve guide, and return it also rotating clockwise. After
reaming, clean valve guide to remove chips.
ST 499767400 VALVE GUIDE REAMER
CAUTION:
Apply engine oil to the reamer when reaming.
If the inner surface of the valve guide is torn, the
edge of the reamer should be slightly ground with an
oil stone.
If the inner surface of the valve guide becomes lus-
trous and the reamer does not chips, use a new reamer
or remedy the reamer.
(8) Recheck the contact condition between valve and
valve seat after replacing valve guide.

6. INTAKE AND EXHAUST VALVE OIL SEAL
Replace oil seal with new one, if lip is damaged or spring
out of place, or when the surfaces of intake valve and valve
seat are reconditioned or intake valve guide is replaced.
1) Place cylinder head on ST1.
2) Press in oil seal to the specified dimension indicated in
the figure by using ST2.

CAUTION:
Apply engine oil to oil seal before force-fitting.
Differentiate between intake valve oil seal and
exhaust valve oil seal by noting their difference in
color.
Color of rubber part:
Intake [Black]
Exhaust [Brown]
Color of spring part:
Intake [Black]
Exhaust [Black]

7. VALVE LASH ADJUSTER
1) Check valve lash adjuster visually.
2) Measure outer diameter of valve lash adjuster.
Outer diameter:
29.959—29.975 mm (1.1795—1.1801 in)
G2M0767
3) Measure inner diameter of bush on cylinder head.
Inner diameter:
29.994—30.016 mm (1.1809—1.1817 in)
CAUTION:
If difference between outer diameter of valve lash
adjuster and inner diameter of bush is over the limit,
replace cylinder head.
Standard:
0.019—0.057 mm (0.0007—0.0022 in)
Limit:
0.100 mm (0.0039 in)
