"TOP" (4) facing upwards, also arrange the openings
of the piston rings so they are out of step with each

The number of each connecting rod corresponds to
the cap coupling number.
The symbol (2) (Fig. 4), punched on the top of the
pistons faces towards the engine flywheel; or the
cavity in the shell of the pistons corresponds to the
position of the oil nozzles.
