Bending check
Figure 106
61695
Check the bending of the connecting rod (5) by comparing
two points C and D of the pin (3) on the vertical plane of the
axis of the connecting rod.
Position the vertical mount (1) of the dial gauge (2) so that this
rests on the pin (3) at point C.
Swing the connecting rod to and fro, establishing the highest
position of the pin and reset the dial gauge (2) in this
condition.
Shift the spindle (4) with the connecting rod (5) and repeat the
check on the highest point on the opposite side D of the pin
(3).
The difference between points C and D must not exceed 0.08
mm.
Connecting rod small end bush check
Figure 107
073535
Check that the bushing in the small end has not come loose
and shows no sign of seizure or scoring. Otherwise replace it.
The bushing (2) is removed and fitted with a suitable drift (1).
When driving it in, make absolutely sure that the holes for the
oil to pass through in the bushing and small end coincide.
Using a reamer, rebore the bushing so as to obtain a diameter
of 59.060 to 59.076 mm.

The piston (1) must be mounted on the connecting rod (2) so
that the ideogram (4), that indicates the fitting direction of the
cylinder liner and the punching (3) of the connecting rod are
seen as in the figure.
NOTE The arrow (5) must face the engine flywheel.
