ONNECTING RODS
Carry out the following controls when overhauling the
connecting rods:
• The bushing conditions and the backlash between them
and the piston pins;
• Axis parallelism;
• Connecting rod bearings.
The bearings are slim-shell type, with anti-friction alloy
which means they cannot be adjusted; if there are signs
of seizing or wear they must be replaced.
When replacing the bearings it may be necessary to true
the crank pin.
Before correcting the crank shaft pin, it is necessary to
measure the diameter of the pin where it shows maximum
wear, as illustrated in the figure; this is to establish which
undersize category the bearing belongs to and how much
the pin must be reconditioned.
Check the axis parallelism
Before fitting the connecting rods, it is necessary to check
their quadrature. This means checking that holes for the
connecting rod small and big end are parallel and coplanar.
The maximum parallelism and complanarity error for the
two axis for the connecting rod small and big end,
measured at a distance of 200 mm, must be ± 0,10 mm.
