Assemble the piston and connecting rod.

1. 

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

2. 

   Gradually heat the piston to about 60°C (140°F).

3. Coat the piston pin with engine oil.

4. 

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

5. 

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

6. 

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

Install the crankshaft bearing cap bolts.

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

2. 

   Install and uniformly tighten the 10 bolts of the crankshaft bearing caps, in several steps, in the sequence shown.

   Torque:

   105 N*m  { 1,071 kgf*cm, 77 ft.*lbf }

Place the connecting rod cap on the connecting rod.

1. Match the numbered connecting rod cap with the connecting rod.

2. 

   Install the connection rod cap with the front mark facing forward.

Tighten the bolt C.

Torque:

19 N*m  { 194 kgf*cm, 14 ft.*lbf, for bolt B. C }

44 N*m  { 449 kgf*cm, 32 ft.*lbf, for bolt A }

Check the piston protrusion for each cylinder.

1. Clean the cylinder block with solvent.

2. Set the piston of the cylinder to be measured to slightly before TDC.

3. 

   Place a dial indicator on the cylinder block, and set the measuring tip as shown in the illustration.

4. Set the dial indicator at 0 mm (0 in.).

   Tech Tips

   
   

   • Use a dial indicator measuring tip as shown in the illustration.

   • Make sure that the measuring tip is square to the cylinder block gasket surface and piston head when taking the measurements.

5. 

   Find where the piston head protrudes most by slowly turning the crankshaft clockwise and counterclockwise.

6. 

   Measure the protrusion of each cylinder at 2 places as shown in the illustration, making a total of 8 measurements.

7. For the piston protrusion value of each cylinder, use the average of the 2 measurements of each cylinder.

   Piston protrusion
   0.68 to 0.98 mm (0.0268 to 0.0386 in.)

   If the protrusion is not as specified, remove the piston and connecting rod assembly and reinstall it.

8. 

   Select the largest piston protrusion value from the measurements made, then select a new appropriate gasket according to the table below.

   Use gasket size
   Gasket Size Protrusion Use B 0.73 to 0.78 mm (0.0287 to 0.0307 in.) Use C 0.78 to 0.83 mm (0.0307 to 0.0327 in.) Use D 0.83 to 0.88 mm (0.0327 to 0.0346 in.) Use E 0.88 to 0.93 mm (0.0346 to 0.0366 in.) Use F 0.93 to 0.98 mm (0.0366 to 0.0386 in.)

   Tech Tips

   There are 3 sizes of new cylinder head gaskets, marked B, D or F accordingly.

   Cylinder head gasket thickness
   Cutout Mark Thickness B 1.40 to 1.50 mm (0.0551 to 0.0591 in.) C 1.45 to 1.55 mm (0.0570 to 0.0610 in.) D 1.50 to 1.60 mm (0.0591 to 0.0630 in.) E 1.55 to 1.65 mm (0.0610 to 0.0650 in.) F 1.60 to 1.70 mm (0.0630 to 0.0669 in.)
