CONNECTING RODS
When overhauling the connecting rods, carry out the
following checks:
■ the condition of the bushings and the clearance
between these and the gudgeon pins;
■ parallelism of the axes;
■ connecting rod bearings.
The bearings are of the thin shell type, in babbitt alloy
that cannot be adjusted; if there are any traces of
seizing or wear they must be replaced.
If the bearings are replaced it may be necessary to
mill the crankshaft pin.
Before grinding the crankshaft pin, it is advisable to
measure the pin diameter in correspondence to the
maximum wear (Fig. 11-81); this is to establish to
which undersize class the bearing should belong and
to what diameter the pin should be ground.
