2. Measure the cylinder liner bore at measuring
point
@ and @ in four different directions (W-W, X-X,
Y-Y, and Z-Z).
3. Calculate the average value of the eight measure-
ments.

(4.1347-4.1362)
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.
Piston Outside Diameter
. -
Measure the piston outside diameter at the measuring
piston shown in the illustration.

Note:
Cylinder liner piston kit clearances are preset. However,
the cylinder liner installation procedure may result in
slight
decreases in cylinder liner
bore clearances.
Alwqs
measure the cylinder
liner bore clearance after
installation to be sure that it is correct.
