   NOTICE:

   Do not tap the tip of the oil jet.

1. Using a 5 mm hexagon wrench, install the 4 oil nozzles with the 4 bolts.
   

   Torque:

   9.0 N*m{ 92 kgf*cm , 80 in.*lbf }

1. Install the upper bearing with the oil groove onto the cylinder and the lower bearing onto the bearing cap.

   NOTICE:

   Do not apply engine oil to the contact surface of the cylinder block or the back side of the bearing.

   HINT:

   Mass production parts do not have identification marks. If reusing a mass production part, measure the clearance of both sides so that the bearing is in the center of the crankshaft bearing cap.

   Specified clearance:

   A - B = within 0.8 mm (0.032 in.)
   

2. Install the thrust washer onto the cylinder block and the front and backside of bearing cap No. 3 with the oil groove facing outward.

3. Apply engine oil to the upper bearing, and then install the crankshaft onto the cylinder block.
   

4. Examine the front marks and numbers and check that the sequence is as shown in the illustration. Then, install the bearing caps onto the cylinder block.
   

5. Apply a light coat of engine oil to the threads and contact surface of the bolt.
   

6. Temporarily tighten the bolts in several steps in the sequence shown in the illustration, and tighten them to the specified torque (step "f").
   

   Torque:

   60 N*m{ 612 kgf*cm , 44 ft.*lbf }

   HINT:

   Check that the crankshaft turns smoothly while tightening the bolts.

7. Mark the front of the crankshaft bearing cap bolts with paint.

8. Retighten the bearing cap bolts by 90° in the same sequence as step "f".
   

9. Check that each paint mark is now at the 90° angle from the front.
   

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

2. Align the front marks of the piston and connecting rod cap.

3. Apply a light coat of engine oil to the piston pin, and then push the piston pin into the hole of the piston and connecting rod cap.
   

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

   NOTICE:

   Do not change the combinations of the pistons and piston pins so that they can be returned to their original location when reassembled.

1. Align the connecting rod bearing and oil grooves, and then install the bearing onto the connecting rod.

   NOTICE:

   Do not apply engine oil to the contact surfaces of the connecting rod, connecting rod cap or the back side of the connecting rod bearing.

1. Install oil ring (Expander) by hand.
   

2. Using a piston ring expander, install the oil ring (side rail) as shown in the illustration.
   

   HINT:

   The upper and lower oil rings are the same.

3. Using a piston ring expander, install No. 1 and No. 2 compression rings with the code marks as shown in the illustration.

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

   NOTICE:

   Make sure that the gap in the oil ring is placed at either position *1 or *2.

1. Apply engine oil to the cylinder walls, pistons and surfaces of the connecting rod bearings.

2. Check that the gap in the piston ring is located correctly.
   

3. Check the front marks. Using a piston ring compressor, install the piston with connecting rod.
   

4. Check that the connecting rod and its cap are in the correct combination and that the front marks are facing correctly, and then install the connecting rod cap onto the connecting rod.
