- 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 does not show seizures.

Otherwise, replace it or adjust it respecting the al-

lowable increases

- Measure the internal diameter of the cylinder with

a bore meter, according to the directions given in

the figure

- Check that the fitting surface with the head is not

dented or distorted.

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

propriate table

See also

Cylinder - piston assy.

Inspecting the piston rings

- Alternatively insert the two sealing rings in the

cylinder

Using the piston, insert the seals perpendicularly

to the cylinder axis.

- Measure the opening of the sealing rings using a

thickness gauge as shown in the photograph

- If the values are higher than the values prescri-

bed in the chart, substitute the rings
