10 N·m {102 kgf·cm, 7 ft·lbf}


4. INSTALL PISTON

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

(b) Gradually heat the piston up to 80 to 90°C (176 to 194°F).

(c) Coat the piston, piston pin and connecting rod with engine oil.

(d) 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.

Service Hole

HINT:

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


(f) Check the fitting condition between the piston and piston pin.

(1) Move the connecting rod back and forth on the piston pin. Check the fitting condition.

If abnormal movement is felt, replace the piston and pin as a set.

(2) Rotate the piston back and forth on the piston pin. Check the fitting condition.

If abnormal movement is felt, replace the piston and pin as a set.

HINT:

Perform "Inspection After Repair" after replacing the piston (See page ).



5. INSTALL PISTON RING SET

(b) Install the upper bearing to the cylinder block as shown in the illustration.

NOTICE:

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

(c) Install the lower bearing onto the bearing cap.


(d) Using a vernier caliper, measure the distance between the crankshaft bearing cap's edge and the lower bearing's edge.

Standard dimension A - B or B - A:

0 to 0.7 mm (0 to 0.0276 in.)

NOTICE:

  • Do not apply engine oil to the bearings and the contact surfaces.
  • Do not allow coolant to come into contact with the bearing inner surface.
  • If any coolant comes into contact with the bearing inner surface, replace the bearing with a new one.

8. INSTALL CRANKSHAFT THRUST WASHER

(a) Apply engine oil to the thrust washers.

Front Mark


(b) Examine the front marks and numbers, and install the bearing caps onto the cylinder block with the front marks as shown in the illustration.

HINT:

The crankshaft bearing cap bolts are tightened in 3 progressive steps.

(c) Apply a light coat of engine oil to the threads and under the heads of the bearing cap bolts.

(d) Step 1:

(1) Using several steps, uniformly install and tighten the 10 bearing cap bolts in the sequence shown in the illustration.

Torque:

20 N·m {204 kgf·cm, 15 ft·lbf}


(e) Step 2:

(1) Tighten the 10 bearing cap bolts again in the sequence shown in the illustration.

Torque:

40 N·m {408 kgf·cm, 30 ft·lbf}

If a crankshaft bearing cap bolt does not meet the specified torque, replace it.

(f) Step 3:

(1) Mark the front of the bearing cap bolts with paint.


(2) Tighten the 10 bearing cap bolts 90° in the same sequence.

(3) Check that the paint marks are now at a 90° angle to the front.

(g) Check that the crankshaft turns smoothly.

10. INSTALL CONNECTING ROD BEARING

(a) Clean the bearing contact surface of the connecting rod and cap, and both surfaces of both bearings.


(b) Install the connecting rod bearings to the connecting rods and connecting rod caps.

(c) Using a vernier caliper, measure the distance between the edges of the connecting rod and connecting rod bearing, and the edges of the bearing cap and connecting rod bearing.

Standard dimension A - B or B - A:

0 to 0.7 mm (0 to 0.0276 in.)

NOTICE:

  • Do not apply engine oil to the bearings and the contact surfaces.
  • Do not allow coolant to come into contact with the bearing inner surface.
  • If any coolant comes into contact with the bearing inner surface, replace the bearing with a new one.
