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.
