PISTON ASSEMBLY

NOTE: Whenever a piston, rings, or pin are out of

tolerance, they must be replaced.

Cleaning/Inspecting Piston

1. Using a non-metallic carbon removal tool, remove

any carbon buildup from the top of the piston.

2. Inspect the piston for cracks in the piston pin,

boss, top, and skirt areas.

3. Inspect the piston for seizure marks or scuffing. If

piston is scored or galled, replace it with a new

one.

4. Inspect the perimeter of each piston for signs of

“blowby” indicated by dark discoloration.

“Blowby” is caused by worn piston rings, exces-

sive carbon in ring grooves, or an out-of-round

cylinder.

Removing Piston Rings

1. Starting with the top ring, slide one end of the ring

out of the ring-groove.

CC400D

2. Remove each ring by working it toward the top 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 piston 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 be within

specifications.

CC995

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 exceeds

specifications, the piston pin must be replaced.

ATV-1070

2. Insert an inside dial indicator into the piston-pin

bore. Take two measurements to ensure accuracy.

The diameter must not exceed specifications. If the

diameter exceeds specifications, the piston must

be replaced.

! 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.
