Check of connecting rod alignment

Figure 65
1
Use apparatus 99395363 (1) to check parallelism of the rod
arms. The maximum permitted tollerance is ± 0.05 mm,
measured at 125 mm from the longitudinal axis of the rod. If
a misalignment exceeding the permitted tolerance is encoun-
tered, replace the rod.
NOTE The body and cap of every connecting rod is marked
with a number indicating the part with which is to be
mated. In addition, the number of the cylinder where
the rod should be installed may be stamped on it.
Therefore, when replacing the rod, it is necessary to
mark the new rod with the same number as the rod
whitch is being replaced.
