NOTE:

Apply a coat of engine oil to the bearing and crankshaft journal.

2. Mount the crankshaft in cylinder block (LH).

3. Apply liquid gasket to the mating surfaces of cylinder block (RH).

CAUTION:

Do not allow liquid gasket to run over into oil passages, bearing grooves, etc.

NOTE:

Install within 5 min. after applying liquid gasket.

Liquid gasket:

THREE BOND 1217G (Part No. K0877Y0100), THREE BOND 1217H or equivalent

Liquid gasket applying diameter:

1.0±0.2 mm (0.039±0.008 in)

4. Attach cylinder block (RH) to cylinder block (LH).

5. Apply a coat of engine oil to the washer and bolt thread.

6. Tighten all bolts in the numerical order as shown in the figure.

Tightening torque:

12 N·m (1.2 kgf-m, 8.9 ft-lb)

7. Retighten all bolts in the numerical order as shown in the figure.

Tightening torque:

18 N·m (1.8 kgf-m, 13.3 ft-lb)

8. Tighten all bolts by 90° in numerical order as shown in the figure.

9. Install the upper bolt to cylinder block.

Tightening torque:

25 N·m (2.5 kgf-m, 18.4 ft-lb)

NOTE:

Remove any liquid gasket squeezed out onto the seal surface between the chain cover and oil pan upper, after tightening the cylinder block connecting bolts.

10. Apply a coat of engine oil to the oil seal inner periphery and outer periphery, and install the rear oil seal using ST1 and ST2.

NOTE:

Use a new rear oil seal.

11. Face the front of the engine up, standing the engine on one end.

12. Attach the piston ring and oil ring to the piston.

(1) Position the top ring gap at (A) in the figure.

(2) Position the second ring gap at (B).

(3) Position the upper rail gap at (C) in the figure.

(4) Position the expander gap at (D) in the figure.

(5) Position the lower rail gap at (E) in the figure.

CAUTION:

Make sure ring gaps do not face the same direction.

Make sure ring gaps are not within the piston skirt area.

Assemble so that the stamp mark N faces towards the top of the piston.

13. Install the #1 piston and connecting rod to the cylinder block.

(1) Apply engine oil to the outer circumference of the piston and in the cylinder block.

(2) Face the front mark of piston (A) towards the front of the engine, and set the piston to the ST.

(3) Using ST, press-fit the piston into cylinder block.

NOTE:

When inserting the piston into the cylinder block, perform according to the items listed below.

Insert while lightly tapping the top of the piston with the handle of a plastic hammer.

Insert while making sure that the large end of the connecting rod does not scratch the cylinder liner.

Insert while continually making sure that the large end of the connecting rod does not touch the crankshaft.

(5) Install the connecting rod cap.

1. Tighten the #1 connecting rod cap bolts to 10 N·m (1.0 kgf-m, 7.4 ft-lb) in numerical order as shown in the figure, then retighten the bolts to 29 N·m (3.0 kgf-m, 21.4 ft-lb) in numerical order as shown in the figure.

2. Using an angle gauge, tighten the connecting rod cap bolts to the specified angle in numerical order as shown in the figure.

Tightening angle:

90° — 95°
