Description of Change

In Step 5, do not use the torque specification of 47.5
to 54 N∙m (35 to 40 lb-ft).
Instead, torque Flange Adapter bolts evenly to
47,5 N·m +/- 2,4 N·m (35 Lb-Ft +/- 1.8 Lb-Ft).
In Step 8 of Table 41, do not use specifications for
head torque given in Table 42. Instead, torque head
bolts/nuts to the following specifications.
20,3 N·m ± 1 N·m (15.0 Lb-Ft ± 0.8 Lb-Ft)
In Step 9, the reference to Table 42 for torquing
head bolts/nuts should be
20,3 N·m ± 1 N·m (15.0 Lb-Ft ± 0.8 Lb-Ft)
