Tightening procedure
(1) 14.5—34.5 N·m {1.5—3.5 kgf·m, 11—25 ft·lbf}
(2) 74.0—82.0 N·m {7.6—8.3 kgf·m, 55—60 ft·lbf}
(3) Loosen all the bolts (until bolts are torque-free).
(4) 14.5—34.5 N·m {1.5—3.5 kgf·m, 11—25 ft·lbf}
(5) 42.5—45.5 N·m {4.4—4.6 kgf·m, 32—33 ft·lbf}

3.  Put a paint mark on each bolt head.

4.  Using the marks as a reference, tighten the bolts by turning each 90°—105° as in Step 2.

Piston, Connecting Rod, Piston Pin Assembly Note

1.  Install one piston pin clip.

2.  Assemble the piston and connecting rod in the direction indicated in the figure.

3.  Apply clean engine oil to the piston pin.
