- Measure the outer diameter of the piston, per-

pendicular to the pin axis.

- Take the measurement in the position shown in

the figure

To classify the cylinder-piston fitting, check the ap-

propriate table

See also

Cylinder - piston assy.

Inspecting the cylinder

• Check that the cylinder exhibits no seizure. If it

does, replace or adjust it, while respecting the al-

lowable oversizes.

• Use a bore meter to measure the cylinder inside

diameter according to the directions shown in the

figure.

• Check that the fitting surface with the head is not worn or deformed

To classify the fitting, refer to the tables.

Cylinder - piston assy.

Inspecting the piston rings

• Alternatively, insert the 2 sealing rings into the

cylinder.

• Insert the rings in an orthogonal position relative

to the cylinder axis, using the piston.

• Measure the sealing ring opening by a feeler

gauge, as shown in the figure.

• If the values are higher than those prescribed on the chart, replace the rings
