Then tighten all bolts to 69 Nm (7.0 kg-m, 51 ft. lbs.) in alphabetical sequence.
3. Back off all bolts by 180° first; back them off by 180° again.
4. Tighten bolts (a) and (b) to 34 Nm (3.5 kg-m, 25 ft. lbs.).
5. Tighten bolts (c), (d), (e) and (f) to 15 Nm (1.5 kg-m, 11 ft. lbs.).
6. Tighten all bolts by 80 to 90° in alphabetical sequence.

CAUTION: Do not tighten bolts more than 90°.

7. Further tighten all bolts by 80 to 90° in alphabetical sequence shown in figure provided.

CAUTION: Ensure that the total "re-tightening angle" [in the former two steps], do not exceed 180°.
