8. Apply new engine oil to the bolt threads and flanges, then loosely install the bearing cap bolts (D) and

bearing cap side bolts (E).

9. Set the crankshaft to bottom dead center (BDC) for the cylinder you are installing the piston in.

10. Apply new engine oil to the piston, inside of the ring compressor, and the cylinder bore.

11. Attach the ring compressor to the piston/ connecting rod assembly, and check that the bearing is

securely in place.

12. Position the piston/connecting rod assembly with the arrow (A) facing the timing belt side of the

engine.

13. Position the piston/connecting rod assembly in the cylinder, and tap it in using the wooden handle of a

hammer (A). Maintain downward force on the ring compressor (B) to prevent the rings from
expanding before entering the cylinder bore.

14. Stop after the ring compressor pops free, and check the connecting rod-to-crank journal alignment

before pushing the piston into place.

15. Measure the diameter of each connecting rod bolt at point A and point B.

16. Calculate the difference in diameter between point A and point B.

Point A-Point B = Difference in Diameter

Difference in Diameter

Specification: 0-0.1 mm (0-0.004 in.)

17. If the difference in diameter is out of tolerance, replace the connecting rod bolt.

18. Line up the mark (A) on the connecting rod and cap, then install the cap.

19. Apply new engine oil to the bolt threads and flanges. Torque the bolts (B) to 20 N.m (2.0 kgf.m, 14

lbf.ft).

20. Mark the connecting rod (A) and bolt head (B) as shown.

21. Tighten the bolt until the mark on the bolt head lines up with the mark on the connecting rod (turn the

bolt 90°).

22. Tighten the bearing cap bolts, and then the bearing cap side bolts to the specified torque in the

sequence as shown. Repeat the torque sequence again to measure the bolts are properly torqued.

NOTE:

Remove the connecting rod bolt if you tightened it beyond the specified
angle, and go back to step 15 of the procedure. Do not loosen it back to
the specified angle.
