There is an arrow marking on the upper side of the cylinder. This must be turned forwards in the cylinder block.
The connecting rods are symmetrical and can be turned freely. Marked rods however must be turned in the same direction.
Assemble the connecting rod and piston with the piston pin. Check that the classification and any numbering for each cylinder/piston diameter and
connecting rod correspond.
Install both the snap rings on the piston pin. Check that the snap rings are positioned correctly in the piston. The opening must be vertical.
Wipe clean around the bearing recess in the connecting rod and the cap.
