CYLINDER BLOCK
 Measure the side clearance of piston ring and piston ring groove
with feeler gauge.
 If the measured value exceeds the limit, replace piston ring, and measure again. If it still exceeds the limit,
replace piston also.
PISTON RING END GAP
 Make sure that the cylinder bore i nner diameter is within the speci-
fication. Refer to "Cylinder Bore Inner Diameter".
 Lubricate with new engine oil to piston and piston ring, and then insert piston ring until middle of cylinder with piston, and measure
the piston ring end gap with feeler gauge.
 If the measured value exceeds the limit, replace piston ring, and measure again. If it still exceeds the limit,
re-bore cylinder and use oversize piston and piston rings.
