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

HINT:

Be sure that the end gap of the snap ring is not aligned with the pin hole cutout portion of the piston.

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

Coat the piston pin with engine oil.

Align the front marks of the piston and connecting rod, insert the connecting rod into the piston, and then push in the piston pin with your thumb until the pin comes into contact with the snap ring.

HINT:

The piston and pin are a matched set.

Check the fitting condition between the piston and piston pin by trying to move the piston back and forth on the piston pin.

Using a screwdriver, install a new snap ring at the other end of the piston pin hole.

HINT:

Be sure that the end gap of the snap ring is not aligned with the pin hole cutout portion of the piston.

Install the oil ring (expander) and 2 side rails by hand.

Using a piston ring expander, install the 2 compression rings with the painted mark on the right side.

   NOTICE:

   1. Do not apply engine oil to the bearings or contact surfaces.
      
   2. Both sides of the oil groove in the cylinder block should be visible through the oil feed holes in the bearing. The amount visible on each side of the holes should be equal.
      
   3. Do not allow coolant to come into contact with the inner surface of the bearing.
      
   4. If any coolant comes into contact with the inner surface of the bearing, replace the bearing with a new one.
      

Install the lower bearing.

1. Install the lower bearings to the crankshaft bearing caps.

2. Using a vernier caliper, measure the distance between the edge of the crankshaft bearing cap and the edge of the lower bearing.
   

   Dimension A - B or B - A:

   0 to 0.7 mm (0 to 0.0276 in.)
   

   NOTICE:

   1. Do not apply engine oil to the bearings or contact surfaces.
      
   2. Do not allow coolant to come into contact with the inner surface of the bearing.
      
   3. If any coolant comes into contact with the inner surface of the bearing, replace the bearing with a new one.
      

Apply new engine oil to the upper bearing and install the crankshaft to the cylinder block.

Push the crankshaft in the rear thrust direction to create clearance and install a thrust washer to the No. 2 journal position with the oil groove facing the front of the engine.

Push the crankshaft in the forward thrust direction to create clearance and install a thrust washer to the No. 2 journal position with the oil groove facing the rear of the engine.

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

Examine the front marks and numbers and set the crankshaft bearing caps on the cylinder block.

Apply a light coat of engine oil to the threads of the crankshaft bearing cap bolts.

Temporarily install the 8 crankshaft bearing cap bolts to the inside positions.

Tighten the 2 bolts for each bearing cap until the clearance between the crankshaft bearing cap and the cylinder block becomes less than 6 mm (0.236 in.).

Using a plastic-faced hammer, lightly tap the crankshaft bearing cap to ensure a proper fit.

Apply a light coat of engine oil to the threads of the crankshaft bearing cap bolts and temporarily install the 8 crankshaft bearing bolts to the outside positions.

Tighten the crankshaft bearing cap bolts.

HINT:

The cap bolts are tightened in 2 progressive steps.

1. Step 1:
   Uniformly tighten the 16 bolts in several steps in the order shown in the illustration.
   

   Torque:

   61 N*m{622 kgf*cm, 45 ft.*lbf}

2. Mark the front side of the crankshaft bearing cap bolts with paint.
   

3. Step 2:
   Tighten the bearing cap bolts 90° in the order shown in step 1.
   

4. Check that the paint marks are now at a 90° angle to the front.
   

Check that the crankshaft turns smoothly.

Install and uniformly tighten the 8 main bearing cap bolts together with 8 new seal washers in several steps in the sequence shown in the illustration.

Torque:

26 N*m{262 kgf*cm, 19 ft.*lbf}

Standard Bolt:

Item	Length
Bolt A	45 mm (1.77 in.)
Bolt B	30 mm (1.18 in.)

Install the bearing to the connecting rod cap.

NOTICE:

1. Clean the contact surfaces of the bearing and connecting rod cap.
   

1. Do not apply engine oil to the bearing or the surface it contacts.
   

Using a vernier caliper, measure the distance between the connecting rod cap edge and connecting rod bearing edge.

Dimension A - B or B - A:

0 to 0.7 mm (0 to 0.0276 in.)
