Crankshaft and Piston Installation

Special Tools Required 

  1. Check the connecting rod bearing clearance with plastigage (see CONNECTING ROD BEARING REPLACEMENT )
  2. Check the main bearing clearance with plastigage (see CRANKSHAFT MAIN BEARING REPLACEMENT )
  3. Install the bearing halves in the engine block and the connecting rods
  4. Apply new engine oil to the inside of the main bearings and the rod bearings
  5. Install the CKP pulse plate to the crankshaft (see CKP PULSE PLATE REPLACEMENT )
  6. Lower the crankshaft (A) into the engine block, being careful not to damage the journals and the CKP pulse plate

  10. Set the crankshaft to bottom dead center (BDC) for the cylinder you are installing the piston in
  11. Apply new engine oil to the piston, the inside of the ring compressor, and the cylinder bore
  12. Attach the ring compressor to the piston/connecting rod assembly, and check that the bearing is securely in place
  13. Position the piston/connecting rod assembly with the arrow (A) facing the timing belt side of the engine block

  15. Stop after the ring compressor pops free, and check the connecting rod-to-rod journal alignment before pushing the piston into place
  16. Measure the diameter of each connecting rod bolt at point A and point B

  17. Calculate the difference in diameter between point A and point B

    Point A-Point B = Difference in Diameter 

    Difference in Diameter 

    Specification 0-0.1 mm (0-0.004 in.) 

  18. If the difference in diameter is out of tolerance, replace the connecting rod bolt
  19. Install the bearing (B), then line up the mark (A) on the connecting rod and the rod cap (C)

  22. Tighten the bolt until the mark on the bolt head lines up with the mark on the connecting rod (turn the bolt 90 °)
    NOTE: Remove the connecting rod bolt if you tightened it beyond the specified angle, and go back to step  16 of the procedure Do not loosen it back to the specified angle. Repeat step  10 to 22 for the remaining cylinders
  23. Tighten the bearing cap bolts, and then the bearing cap side bolts to the specified torque in the sequence as shown Repeat the torque sequence again to ensure the bolts are properly torqued

  24. Remove all of the old liquid gasket from the engine block end cover mating surfaces, the bolts, and the bolt holes
  25. Clean and dry the engine block end cover mating surfaces
  26. Apply a light coat of new engine oil to the lip of the crankshaft oil seal
  27. Using the driver handle, 15 x 135 L and the oil seal driver attachment, 106 mm, drive in the new crankshaft oil seal until the oil seal driver attachment bottoms on the engine block end cover

  28. Apply liquid gasket, P/N 08717-0004, 08718-0003, or 08718-0009, evenly to the engine block mating surface of the engine block end cover and to the inside edge of the threaded bolt holes Install the component within 5 minutes of applying the liquid gasket
    NOTE:
    • Apply a 2.5 mm (0.098 in) diameter bead of liquid gasket along the broken line
    • If you apply liquid gasket P/N 08718-0012, the component must be installed within 4 minutes
    • If too much time has passed after applying the liquid gasket, remove the old liquid gasket and residue, then reapply the new liquid gasket
