Note: Align Hole (X) in piston pin bushing (8) with the hole in connecting rod (1) .

3. Install piston pin bushing (8) in connecting rod (1) .

4. Use a pin boring machine in order to obtain the proper diameter of the bushing after installation. The clearance between the bushing and the piston pin is -0.001 to 0.007 mm (-0.0001 to 0.0003 inch).

5. Use the following procedure with Tooling (B) to install the piston rings on piston (2) .

   1. Install oil control piston ring (7) in the groove that is lowest on the piston. Latch pin (9) that is on oil control ring (7) must be inside the ends of spring (10) .

      Note: Ensure that the latch pin that is on the oil control ring is 180 degrees from the oil control ring gap.

   2. Install intermediate piston ring (6) with the tapered face into the second groove on the piston. The scribe mark and Notch (Y) must be toward the top of the piston.

   3. Position the piston ring gaps at 90 degrees away from each other.

   4. Install top piston ring (5) with the barrel face and the molybdenum insert into the top groove on the piston. The scribe mark must be toward the top of the piston.

6. Align Identification Marks (Z) on connecting rod (1) and piston (2) .

   Note: The Shibaura name inside the piston must align with the stamped number on the connecting rod.

7. Install piston pin (3) into piston (2) and connecting rod (1) .

   Note: If the piston pin cannot be installed by hand, raise the temperature of the piston in order to install the piston pin.

8. Use Tooling (A) to install retaining rings (4) .

End By: Install the pistons and the connecting rods. Refer to Disassembly and Assembly, "Pistons and Connecting Rods - Install".
