3. Install the main bearings paying attention to their position and direction.
   • The main bearing with an oil hole and groove goes on the cylinder block. The one without them goes on the lower cylinder block.
   • Only the main bearing (on the cylinder block) for No. 3 journal has different specifications.
   • Before installing the bearings, apply engine oil to the bearing friction surface (inside). Do not apply oil to the back surface, but thoroughly clean it.
   • When installing, align the bearing stopper to the notch.
   • Make sure that the oil holes on the cylinder block and those on the corresponding bearing are aligned.

   • Wipe off completely any protruding Silicone RTV Sealant on the exterior of engine.
   • Check crankshaft side clearance. Refer to "INSPECTION AFTER DISASSEMBLY ".
   • After installing the bolts, make sure that the crankshaft can be rotated smoothly by hand.

• Press the oil seal between cylinder block and crankshaft with a suitable drift.
• Be careful not to touch the grease on the oil seal lip.
• Be careful not to cause scratches or burrs when pressing in the rear oil seal.

1. Using a snap ring pliers, install the snap ring to the grooves of the piston's rear side.
   • Insert the piston pin snap ring fully into groove.
2. Install the piston to the connecting rod.
   • Using a heat gun, heat the piston [approximately 60° - 70 C° (140° - 158°F)] until the piston pin can be pushed in by hand without excessive force. From the front to the rear, insert the piston pin into the piston and the connecting rod.
   • Assemble so that the front mark on the piston crown and the oil holes and the cylinder No. on the connecting rod are positioned as shown in the figure.
3. Install the piston pin snap ring into the front of the piston.
   • Check that the connecting rod moves smoothly.

• Rotate the crankshaft so the pin corresponding to the connecting rod to be installed is at the bottom dead center position.
• Apply engine oil sufficiently to the cylinder bore, piston, and crankshaft pin.
• Match the cylinder position number with the cylinder No. on the connecting rod for installation.
• Using tool as shown in the figure, install the piston with the front mark on the piston crown facing the front of the engine.
  CAUTION: Be careful not to damage the crankshaft pin, resulting from an interference of the connecting rod big end.
