1.Apply a coat of engine oil to the washers and bolt threads.
2.Tighten all bolts to 29 Nm (3.0 kgf-m, 22 ft. lbs.) in alphabetical sequence.
3.Tighten all bolts to 69 Nm (7.0 kgf-m, 51 ft. lbs.) in alphabetical sequence again.
4.Back off all bolts by 180° first; back them off by 180° again in reverse order of installation.
5.Tighten all bolts to 49 Nm (5.0 kgf-m, 36 ft. lbs.) in alphabetical sequence.
6.Tighten all bolts 80 to 90° in alphabetical sequence.
7.Tighten all bolts by 40 to 45° in alphabetical sequence again.

CAUTION: Do not tighten the bolts by more than 45°.

8.Further tighten all bolts (A) and (B) by 40 to 45°.

CAUTION: Ensure that the total "re-tightening angle" in the previous two steps do not exceed 90°.
