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.

1.

Installation Torque.

(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.

NOTE

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