Caution: Handle the piston carefully. Worn piston rings are sharp and may cause bodily injury.

1. Disassemble the piston rings. Use a suitable tool in order to expand the rings. The piston rings must not be reused.

Important: Two retainers hold the piston pins in place. No special tools are required to remove or install the retainers or the piston pins. If the retainers are not damaged, reuse the retainers. Ensure that the piston pin is not damaged.

2. Disassemble the piston pin retaining clips.
3. Disassemble the piston pin.

Important: Install the piston onto the connecting rod in either direction.

Notice: Install the piston pin retainers correctly in the retaining groove during assembly in order to avoid engine damage.

5. Use the following procedure in order to assemble the piston pin and the retainer:

5.1. | Coat the piston pin with oil.
