Checking the connecting rod
When examining the connecting rods, check that:
•
Bushing conditions and bushings-pins clearance;
•
Shaft parallelism;
•
Connecting rod bearings.
These are thin shell bearings, anti-friction alloy that does not allow for any adaptation; replace them
immediately if seizing or wear marks are found.
Upon replacing the bearings it may be necessary to ream the crankshaft pin.
Before reaming the crankpin, measure the pin diameter (B) comparing it with the maximum wear al-
lowed, as indicated in the figure; this defines what kind of undersizing the bearing should have and to
which diameter the pin (B) should be reamed.
Checking shaft parallelism
Check shafts for squaring before fitting them.
It is therefore necessary to check that the head holes and the rod small end are parallel and on the
same plane.
The maximum parallelism and plane error of the two head shafts and connecting rod small end should
be +/- 0.10 mm (0.00393 inch).
