Installation
1. If the piston is damaged, check the clearance and axial runout of the piston rings.
2. Lubricate the piston pin and connecting rod bushings with oil.
3. Install the piston so that the arrow points in the direction of travel and the locking grooves (arrows) of the connecting rod are facing outward.
4. Press the piston pin into the piston by hand.
