In case of excessive wear, replace the connecting rod. The small end bush must be in good condition and
firmly driven into its seat. Check the parallelism error measured at 100 mm from the connecting rod
longitudinal axis:
it must be H-h lower than 0.02 mm (H standard height when new is 124 mm); change the con-rod if it is
not so.
Connecting rod big-end diameter must be within the specified limits.
It is preferable to use crankshafts and connecting rods of the same size class.
