WEIGHT CONTROL FOR CRANKSHAFT BALANCING
The weight of the connecting rods together with screws must be balanced.
A difference of 4 grams (0.14 oz) is permissible.
To balance the crankshaft from a static point of view, it is necessary to apply the following weight on
the crank pin: 1810 g (63.84 oz).
Checking the connecting rod
CONNECTING RODS
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 comparing it with the maximum wear allowed,
as indicated in the figure; this defines what kind of undersizing the bearing should have and to which
diameter the pin 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 connecting rod small end are parallel and
on the same plane.
The maximum parallelism and plane error of the two shafts of the head and rod small end, measured
at 200 mm (7.873 inch) should be +/- 0.10 mm (0.00393 inch).
