• The connecting rod is made of structurally sintered alloy to improve rigidity.

• The connecting rod, the piston, and the piston pin are shrinkage fit, and cannot be disassembled.

• The connecting rod bolts are plastic region tightening bolts tightened in two steps to insure tightening stability.

• There is no positioning tab for the large end of the connecting rod bearing. When installing the bearing, measure so that the connecting rod and the bearing cap are positioned in the center.

• After the large end of the connecting rod and the connecting rod cap are cast as a single unit, they are fractured and separated into the connecting rod and the cap. This fracture line on the surface is used as the alignment mark for the connecting rod and cap.

• The upper and lower bearing of the connecting rod bearing is made of aluminum alloy.

• There are three kinds of connecting rod bearings depending on the oil clearance.
