4–16 ENGINE ASSEMBLY II

Cylinder Liner Bore Measurement

1. Locate the two measuring points.

Cylinder Liner Measuring Point 1: 20 mm (0.788 in)

Cylinder Liner Measuring Point 2: 105 mm (4.173 in)

2. Measure the cylinder liner bore at measuring point

1 and 2 in four different directions (W–W, X–X,

Y–Y, and Z–Z).

3. Calculate the average value of the eight measure-

ments.

mm (in)

Relation between liner bore and piston grade mm (in)

Note:

It is most important that the correct piston grade be

used. Failure to select the correct piston grade will

result in piston seizure.

Always measure the cylinder bore and select the appro-

priate piston grade.
