INSPECTION AND REPAIR 1C
INSPECTION AND REPAIR
1. Clean all parts, taking care to remove any gasket fragments, dirt, oil or grease, carbon, moisture
residue, or other foreign materials.
2. Inspect and repair must be performed in the order specified.
Caution
Be careful not to damage the joints or friction surfaces of aluminum alloy components (such
as the cylinder head or pistons).
86U01X-077
Cylinder Head
1. Inspect the cylinder head for damage, cracks, and
leakage of water or oil. Replace if necessary.
2. Measure the cylinder head distortion in the seven
directions shown in the figure.
Distortion: 0.10 mm (0.004 in) max.
76G01C-098
3. If the cylinder head distortion exceeds specificati-
on replace the cylinder head.
Height:
133.9—134.1 mm (5.272—5.280 in)
Caution
Do not attempt to repair a cylinder head by
milling or grinding.
76G01C-099
4. Measure the manifold contact surface distortion in
the three directions shown in the figure.
Distortion: 0.20 mm (0.008 in) max.
5. If distortion exceeds specification replace the cyl-
inder head.

Replacement of valve guide
Caution
When the valve guide is replaced, check the
gap between the valve and guide once again.
The valve seal should be installed after in-
spection and repair of the valve seat.
Don't misassemble the valve guides because
intake and exhaust valve guides have a differ-
ent seat.
Intake side valve guide longer
Exhaust side valve guide shorter
Removal
1. Gradually heat the cylinder head in water to ap-
prox. 90°C (194°F).
76G01C-106
2. Remove the valve guide from the side opposite the
combustion chamber with the SST.
