Assembly Procedure

ORIENTATION AND PISTON INSTALLATION DIAGRAM The hole for the gudgeon pin housing is NOT symmetrical with the piston pin. This offset is necessary to limit the lateral forces perpendicular to the cylinder liner. The offset follows the rotation direction of the crankshaft and, for this reason, the pistons on the right-hand bank are different from those on the left-hand bank.
