The maximum parallelism deviation of the two crankshaft axes (connecting rod pin and main journals
on flywheel side and timing system side) should not exceed 0.02 mm (0.0009 in) at 40 mm (1.5748 in)
distance.
Checking the connecting rod
•
Check using a micrometer the measure of the connecting rod pin orthogonal axes an in the
working area of the small ends, check the measure of the small ends seats on the timing
system side and on the flywheel side.
•
Assemble the connecting rod without small ends and tighten the connecting rod screws to
the prescribed torque. Measure the outer diameter of small ends seats with a dial gauge
graduated in hundredths of a millimetre and the thickness of both small ends with a round
tip micrometer.
•
Check the bushings pressed in the small end of the connecting rod for notches due to seizing
or deep scoring; replace as required.

Assembling the connecting rod
•
Before assembly, take careful note of the reference markings and the correct direction of
installation.
•
Connecting rods are available in two classes (A/blue - B/white, identified respectively by a
white or blue dot in the zone indicated by the letter X in the drawing). These must be as-
sembled correctly with the crankshaft, which is categorised into two different classes in
