CONNECTING RODS AND PISTONS
5-83
1. Check:
• Piston wall
• Cylinder wall
Vertical scratches
→
Replace the upper
crankcase, and replace the piston and piston
rings as a set.
2. Measure:
• Piston-to-cylinder clearance

a. Measure cylinder bore “C” with the cylinder
bore gauge.
TIP
Measure cylinder bore “C” by taking side-to-side
and front-to-back measurements of the cylinder.
Then, find the average of the measurements.
b. If out of specification, replace the upper
crankcase, and replace the piston and piston
rings as a set.
c. Measure piston skirt diameter “D” “a” with the
micrometer.
d. If out of specification, replace the piston and
piston rings as a set.
e. Calculate the piston-to-cylinder clearance
with the following formula.
f. If out of specification, replace the upper
crankcase, piston, and piston rings as a set.

CHECKING THE PISTON RINGS
1. Measure:
• Piston ring side clearance
Out of specification
→
Replace the piston
and piston rings as a set.
TIP
Before measuring the piston ring side clearance,
eliminate any carbon deposits from the piston
ring grooves and piston rings.
