1. Apply engine oil to the connecting rod small end bushing and to the piston pin bore of the piston.
2. Install the piston pin into the piston and connecting rod.

Note:
* For the right bank piston and connecting rod assemblies, reassemble so the grade mark on the connecting rod faces the right side of the engine and the piston front mark faces the front of the engine.
* For the left bank piston and connecting rod assemblies, reassemble so the grade mark on the connecting rod faces the left side of the engine and the piston front mark faces the front of the engine.

3. Install the piston pin retaining rings.




4. Apply engine oil to the piston ring grooves.
5. Install the piston rings using a piston ring expander.





Note: The 2N mark on the 2nd compression ring (2) must face upwards. The piston has a groove between the 1st and the 2nd compression rings to allow for expansion of blowby gases. No ring is to be installed in this groove.

6. Install the piston rings so that the gaps are orientated as follows:

* The top compression ring (1) and second compression ring (2) gaps should be 180 degrees from each other.
* The inner oil ring expander ring (3) gap should be 180 degrees from the oil ring rail (4) gap.
* The ASSEMBLED oil ring gaps should be 90 degrees from the compression ring gaps.
