Selecting connecting rods

If a selection class of connecting rods is fit on
the crankshaft that is not class D - D, it is not a
problem.
It is essential, for proper crankshaft balance, that
if one connecting rod is replaced the other one fit
on the same crank pin must also be replaced:
•
if the piston 1 connecting rod is re-
placed, the one relative to piston 2
must also be replaced and vice versa;
•
if the piston 3 connecting rod is re-
placed, the one relative to piston 4
must also be replaced and vice versa;
The connecting rod class is stamped on its left
side, viewed from the front, from the side with the
bevelling on the big end hole.
ONLY ONE CONNECTING ROD SELECTION CLASS IS
SPECIFIED FOR REPLACEMENT PARTS, INDICATED
WITH THE LETTERS D-D.
