• The connecting rod bolts are plastic region tightening bolts, to be tightened in two steps to insure tightening stability.
• There shall be no positioning tab for the connecting rod bearing. When installing the bearing, measure the position of the bearing so that the position gets to the center of the connecting rod and the bearing cap, and install it.
