      NOTE:
      • Clean the sealing face before assembling two parts.
      • Remove harmful foreign materials on the sealing face before applying sealant.
      • When applying sealant gasket, sealant must not protrude into the inside of cylinder block.
      • To prevent leakage of oil, apply sealant gasket to the inner threads of the bolt holes.

      Tightening torque 

      Main bearing cap bolts (1~20)

      37.3~41.2 N.m (3.8~4.2 kgf.m, 27.5~30.4 lb-ft) + 120°

      Flange bolts (21~35)

      21.6 ~ 25.5 N.m (2.2 ~ 2.6 kgf.m, 15.9 ~ 18.8 lb-ft)

      NOTE:
      • Always use new main bearing cap bolts.
      • If any of the bearing cap bolts are broken or deformed, replace it.

    2. Check that the crankshaft turns smoothly.
  8. Check crankshaft end play.
  9. Install the piston and connecting rod assemblies.
    NOTE:
    • Before installing the pistons, apply a coat of engine oil to the ring grooves and cylinder bores.
    • The piston front mark (A) and the connecting rod front mark (B) must face the timing chain side of the engine.

    1. Install the ring compressor, check that the bearing is securely in place, then position the piston in the cylinder, and tap it in using the wooden handle of a hammer.
    2. Stop after the ring compressor pops free, and check the connecting rod-to-check journal alignment before pushing the piston into place.
    3. Apply engine oil to the bolt threads. Install the rod caps with bearings, and torque the bolts.

      Tightening torque: 

      22.6~26.5N.m (2.3~2.7kgf.m, 16.6~19.5lb-ft) + 98°~102°
