wise. After reaming, clean the valve guide to re-
move chips.
ST 499765900 VALVE GUIDE REAMER
NOTE:
•Apply engine oil to the reamer when reaming.
•If the inner surface of valve guide is damaged,
the edge of reamer should be slightly ground with
oil stone.
•If the inner surface of valve guide becomes lus-
trous and the reamer does not chip, use a new
reamer or remedy the reamer.
(8) Recheck the contact condition between
valve and valve seat after replacing the valve
guide.
4. INTAKE AND EXHAUST VALVE
1) Inspect the flange and stem of valve, and re-
place if damaged, worn or deformed, or if “H” ex-
ceeds the standard, or offset wear occurs.

5. VALVE SPRING
1) Check the valve springs for damage, free length,
and tension. Replace the valve spring if it is not
within the standard value presented in the table.
2) To measure the squareness of the valve spring,
stand the spring on a surface plate and measure its
deflection at the top of spring using a try square.
6. INTAKE AND EXHAUST VALVE OIL
SEAL
In the following case, pinch and remove the oil seal
from valve using pliers, and then replace it with a
new one.
•When the lip is damaged.
•When the spring is out of the specified position.
•When readjusting the surfaces of intake valve
and valve sheet.
•When replacing the intake valve guide.
1) Set the cylinder head on ST1.
2) Press-fit the oil seal to the specified dimension
indicated in the figure using ST2.

NOTE:
•Apply engine oil to oil seal before press-fitting.
•When press-fitting the oil seal, do not use a ham-
mer or strike in.
7. VALVE LIFTER
1) Check the valve lifter visually.
2) Measure the outer diameter of valve lifter.
Outer diameter:
32.959 — 32.975 mm (1.2976 — 1.2982 in)
3) Measure the inner diameter of valve lifter hole of
cylinder head.
Inner diameter:
32.994 — 33.016 mm (1.2990 — 1.2998 in)
NOTE:
If difference between outer diameter of valve lifter
and inner diameter of valve lifter hole is out of the
standard or offset wearing is emitted, replace the
cylinder head.

Cylinder Block
MECHANICAL
E: INSPECTION
1. CYLINDER BLOCK
1) Visually check for cracks and damage. Especial-
ly, inspect the important parts using liquid pene-
trant tester.
2) Check the oil passages for clogging.
3) Inspect the crankcase surface that mates with
cylinder head for warping by using a straight edge.
Standard height of cylinder block:
202 mm (7.95 in)
2. CYLINDER AND PISTON
1) The cylinder bore size is stamped on the front
upper face of the cylinder block.
NOTE:
•Measurement should be performed at a temper-
ature of 20°C (68°F).
•Standard sized pistons are classified into two
grades, “A” and “B”. These grades should be used
as guide lines in selecting a standard piston.
Standard diameter:
A: 89.205 — 89.215 mm (3.5120 — 3.5124 in)
B: 89.195 — 89.205 mm (3.5116 — 3.5120 in)
2) How to measure the inner diameter of each cyl-
inder:
Measure the inner diameter of each cylinder in both
the thrust and piston pin directions at the heights as
shown in the figure, using a cylinder bore gauge.
NOTE:
Measurement should be performed at a tempera-
ture of 20°C (68°F).
Cylindricality:
Standard
0.030 mm (0.0012 in)
Out-of-roundness:
Standard
0.010 mm (0.0004 in)
3) When the piston is to be replaced due to general
or cylinder wear, determine a suitable sized piston
by measuring the piston clearance.
