The main points of assembly of the diesel generator piston rod set are as follows:

1. Press-fit connecting rod copper sleeve. When installing the connecting rod copper sleeve, it is best to use the press or the vise. Do not use a hammer to strike; the oil hole or oil groove on the copper sleeve should be aligned with the oil hole on the connecting rod to ensure lubrication.

2. Assemble the piston and connecting rod. When assembling pistons and connecting rods, pay attention to their relative position and direction.

3. Cleverly install the piston pin. The piston pin and the pin hole are in an interference fit. When installing, the piston should be evenly heated to 90 °C ~ 100 °C in water or oil. After taking out, put the tie rod in the proper position between the piston pin hole, and then install the oil-coated piston pin in the given direction. Into the piston pin hole and the connecting rod copper sleeve

4. Installation of the piston ring. When installing the piston ring, pay attention to the position and sequence of each ring.

5. Install the connecting rod set.
