- Measure the outer diameter of the gudgeon pin.

Characteristic

Pin outside diameter

14 (+0 -0.004) mm

- Measure the diameter of the housings on the pis-

ton.

Characteristic

Standard diameter

14 (+0.006 +0.001) mm

- Carefully clean the seal housings.

- Measure the coupling clearance between the

sealing rings and the piston grooves using suitable

sensors, as shown in the diagram.

- If the clearance is greater than that indicated in

the table, replace the piston.

- Check the clearance upon mounting (A) of the

bands:
