- Calculate the piston pin coupling clearance.

Fitting clearance

Pin coupling clearance

13 +0.010+0.005mm

0.005 ÷

0.014 mm

- Measure the outside diameter of the piston, perpendicular to the gudgeon pin axis.

- Carry out the measurement at 27 from the piston crown as shown in the figure.

Inspecting the cylinder

- Using a bore meter, measure the inner cylinder

diameter at three different points according to the

directions shown in the figure.

- Check that the coupling surface with the head is

not worn or misshapen.

- Pistons and cylinders are classified into catego-

ries based on their diameter. The coupling is car-

ried out in pairs (A-A, B-B, C-C, D-D).

Characteristic

Maximum allowable run-out:

0.05 mm
