NOTE
Connecting rods installed in a given engine must not differ among each other by more
than 9 grams.
To determine weight group, weigh the complete connecting rod without bearing inserts.
When measured at a point of 250 mm between centers, deviation from bore parallel
alignment must not
exceed 0.1 mm. At the same time, twist in relation to both bores must not exceed 1.5 mm.
