Use Tooling (C) to install piston rings (6) on piston (3).
The ends of the oil control piston ring should be 180 degrees away from the oil ring end gap. The white-colored section of the oil ring spring should also be visible at the oil ring end gap.
Install the intermediate ring with the side that is marked "UP" toward the top of the piston. Position the intermediate ring with the green strip on the right side of the end gap.
Install the top piston ring with the red strip on the right side of the end gap.
The piston ring end gaps must be approximately 120 degrees away from each other after installation.
