•  Connecting rod is made of structural sintered alloy to improve rigidity.

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

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

•  There is 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.

•  The big end of the connecting rod and the connecting rod cap were originally formed as a single unit and then it was cut into the connecting rod and the cap. The form of the cutting surface is used for the alignment mark for the connecting rod and the cap.

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

•  The connecting rod bearings can be selected from three types including the standard, 0.25 mm {0.01 in}over-size and 0.50 mm {0.02 in} over-size.

•  A steel connecting rod with high rigidity has been adopted.

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

•  A connecting rod bearing with positioning tabs has been adopted to improve accuracy in installation.

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

•  The connecting rod bearings can be selected from three types including the standard, 0.25 mm {0.01 in} over-size and 0.50 mm {0.02 in} over-size.
