2. Remove each ring by working it toward the dome of
the piston while rotating it out of the groove.

NOTE: If the existing rings will not be replaced with
new ones, note the location of each ring for proper
installation. When installing new rings, install as a
complete set only.
Cleaning/Inspecting Piston Rings
1. Take an old piston ring and snap it into two pieces;
then grind the end of the old ring to a 45° angle and
to a sharp edge.
2. Using the sharpened ring as a tool, clean carbon from
the ring-grooves. Be sure to position the ring with its
tapered side up.
Measuring Piston-Ring End Gap
(Installed)
1. Place each compression ring in the wear portion of
the cylinder. Use the piston to position each ring
squarely in the cylinder.
2. Using a feeler gauge, measure each piston-ring end
gap. Acceptable ring end gap must not exceed speci-
fications.

Measuring Piston Pin (Outside
Diameter) and Piston-Pin Bore
1. Measure the piston pin outside diameter at each end
and in the center. If measurement is not within speci-
fications, the piston pin must be replaced.

2. Insert an inside dial indicator into the piston-pin
bore. The diameter must not exceed specifications.
Take two measurements to ensure accuracy.
ATV-1069
Measuring Piston Skirt/Cylinder
Clearance
1. Measure the cylinder front to back in six places.
CC127D
2. Measure the corresponding piston diameter at the
recommended point above the piston skirt at a right
angle to the piston-pin bore. Subtract this measure-
ment from the measurement in step 1. The difference
(clearance) must not exceed specifications.
CAUTION
Improper cleaning of the ring-grooves by the use of the
wrong type of ring-groove cleaner will result in severe
damage to the piston.
