CYLINDER BLOCK/PISTON INSPECTION
CYLINDER BLOCK DISTORTION
Check the gasket surface of the cylinder block for distortion. Use
a straightedge and thickness gauge. Take clearance readings at
several places. If any reading exceeds the service limit, replace
the cylinder block.
" 09900-20803: Thickness gauge
# Cylinder block distortion
Service Limit: 0.2 mm (0.008 in)
CYLINDER BORE
Measure the cylinder bore diameter at six places. If any one of
the measurements exceed the limit, overhaul the cylinder and
replace the piston with an oversize piston. The remaining cylin-
ders must also be rebored accordingly; otherwise, the imbalance
might cause excessive vibration.

# Cylinder bore
Standard: 79.000 – 79.015 mm (3.1102 – 3.1108 in)
Service Limit: 79.080 mm (3.1134 in)
PISTON DIAMETER
Measure the piston diameter using the micrometer at 15 mm from
the skirt end.
If the piston diameter is less than the service limit, replace the
piston.
