CHECKING THE CYLINDER AND PISTON

1. Check:

• Piston wall
• Cylinder wall

Vertical scratches

→

Replace the cylin-

der, and the piston and piston rings as a
set.

2. Measure:

• Piston-to-cylinder clearance

▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼

a. Measure cylinder bore “C” with the cylinder

bore gauge.

NOTE:

Measure cylinder bore “C” by taking side-to-
side and front-to-back measurements of the
cylinder. Then, find the average of the mea-
surements.

b. If out of specification, replace the cylinder,

and the pistons and piston rings as a set.

c. Measure piston skirt diameter “P” with the

micrometer.

4 mm (0.16 in) “a” from the bottom edge of
the piston

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.

If out of specification, replace the cylinder,
and the 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.

NOTE:

Before measuring the piston ring side clear-
ance, eliminate any carbon deposits from the
piston ring grooves and piston rings.
