    		 1. Remove the connecting rod caps.

    2. Apply a coat of new engine oil to the connecting rod bearings.

    3. Install the ring compressor, and check that the bearing is securely in place.

    4. Apply new engine oil to the piston, inside of the ring compressor, and the cylinder bore, then attach the ring compressor to the piston/connecting rod assembly.

    5. Position the piston/connecting rod assembly with the arrow (A) facing the cam chain side of the engine block.

    		 6. Position the piston/connecting rod assembly in the cylinder, and tap it in using the wooden handle of a hammer (A). Maintain downward force on the ring compressor (B) to prevent the rings from expanding before entering the cylinder bore.

    7. Stop after the ring compressor pops free, and check the connecting rod-to-rod journal alignment before pushing the piston into place.
  4. Oil Jet - Install
  5. Crankshaft Main Bearing Clearance - Inspect
  6. CKP Pulse Plate - Install

    NOTE:  Apply new engine oil to the threads and flange of the CKP pulse plate mounting bolts.

  7. Crankshaft - Install

    NOTE: 

    • Apply a coat of new engine oil to the main bearings.
    • Hold the crankshaft so that rod journal No. 2 and rod journal No. 3 are straight up, and lower the crankshaft into the engine block.
  8. Thrust Washer - Install
