3) Once the four cylinders have been mechanized measure
each one using an internal dimensions caliper adjusted to
the nominal diameter size of mechanized cylinders.
Nominal diameter size to which the calliper must be
adjusted: 97,5
-0,11
Measuring should be done as follows:
• Carry out three measurements at three different heights of
the cylinder as shown and at two planes perpendicular
one to another. One plane is parallel to the longitudinal
axle of engine (A) and another perpendicular (B).
• The mean diameter D

med must be specified and
calculated as follows

NOTE:
The values between brackets are the heights to which
measurements from the upper face of block have to
be performed.
Mean diameter D1 med of mechanized cylinders to
be lined: 97,390 ÷ 97,450 mm
