h
flywheel housing. Do not tighten.
g. Remove the guide studs and install the remaining capscrews.
h. Tighten the eight housing capscrews (3, Figure 3-8) to 50 ft-lb (65 N ) torque. Tighten in the
m
sequence shown in Figure 3-9.
FIGURE 3-9. Generator Housing Torque Sequence.
i.
Tighten the six flywheel coupling capscrews (8, Figure 3-8) to 352 ft-lb (476 N ). Tighten in the
m
sequence shown in Figure 3-10.
j.
