1.

Installation Torque.

NOTE

If a component has a critical tightening sequence, it will be illustrated in that particular

work package; otherwise, use the general sequence charts provided in Figure 1.

(a)

Tighten nuts twice in a crisscross pattern using a torque wrench.

The first time nut is torqued,

apply approximately 75% of final torque value.

(b)

Repeat sequence a second time until 100% of final torque value has been obtained for each nut.

2.

Check Torque.

NOTE

When one or more screws are loose, check torque for all bolts on the component.

Tighten nuts in a crisscross pattern using a torque wrench.
