  3. INSTALL PISTON WITH PIN SUB-ASSEMBLY


    1. A01XFJX

      Using a small screwdriver, install a new snap ring on one side of the piston pin hole.

    2. A01XEJP

      Gradually heat the piston to approximately 80°C (176°F).

    3. Coat the piston pin with engine oil.

      Align the front marks of the piston and connecting rod, connect the connecting rod to the piston, and then push in the piston pin with your thumb.

    5. Check the fit between the piston and piston pin. Try to move the piston back and forth on the piston pin.

    6. A01XEC7

      Using a small screwdriver, install a new snap ring on the other side of the piston pin hole.

      *1 No. 1 Piston Ring
      *2 Oil Ring
      *3 Coil
      *4 No. 2 Piston Ring
      *5 Front Mark (Arrow)

      Position the piston rings so that the ring ends are as shown in the illustration.

      Note

      Do not align the ring ends.

  5. INSTALL CRANKSHAFT BEARING

    A01XGNM

    Tech Tips

    Upper bearings have an oil groove and oil hole. Lower bearings do not.


    1. Align the bearing claw with the claw groove of the cylinder block and push in the 5 upper bearings.

    2. A01XCJ0

      Align the bearing claw with the claw groove of the crankshaft bearing cap and push in the 5 lower bearings.

  6. INSTALL CRANKSHAFT

    A01XIVI

    1. Place the crankshaft on the cylinder block.

    2. Push the crankshaft in one direction and install one thrust washer to the No. 5 journal position with the oil groove facing outward.

    3. Push the crankshaft in the opposite direction and install the other thrust washer to the No. 5 journal position with the oil groove facing outward.

    4. A01XI9G

      Install the 2 thrust washers to the No. 5 bearing cap with the grooves facing outward.

    5. A01XMCQ

      Install the 5 crankshaft bearing caps to their proper locations.

    6. A01XD65E11

      Install the crankshaft bearing cap bolts.

      Tech Tips


      • The crankshaft bearing cap bolts are tightened in 2 progressive steps.

      • If a crankshaft bearing cap bolt is broken or deformed, replace it.


      1. Apply a light coat of engine oil to the threads and under the bolt heads of the crankshaft bearing cap bolts.

      2. Install and uniformly tighten the 10 bolts of the crankshaft bearing caps in several passes in the sequence shown in the illustration.

        Torque:
        50 N*m  { 510 kgf*cm, 37 ft.*lbf }

        If any one of the bearing cap bolts does not meet the torque specification, replace the bearing cap bolt.

        *1 Painted Mark
        *a Front

        Mark the front of each crankshaft bearing cap bolt with paint.

      4. Tighten the crankshaft bearing cap bolts by 90° in the numerical order shown in the previous illustration.

      5. Check that the painted marks are now at a 90° angle to the front.

    7. Check that the crankshaft turns smoothly.

    8. Check the crankshaft thrust clearance.

  7. INSTALL CONNECTING ROD BEARING


    1. A01XIYY

      Align the bearing claw with the groove of the connecting rod or connecting rod cap.

    2. Install the bearings to the connecting rod and connecting rod cap.
