9.2 Reassembly
1. Reinstall the alternator end bracket with the exciter
field. Feed the exciter leads into the hole in the top
of the stator housing. Torque the mounting bolts to
38.0 Nm (28 ft. lbs.). See Figure 9-9.
2. Gently insert the rotor into the stator housing. Be
careful to avoid damaging the rotor assembly or the
stator during installation. See Figure 9-10.
3. Secure the rotor to the alternator with a bolt, plate,
and 4 washers. The end of the rotor shaft is
threaded for this purpose. See Figure 9-5.
4. Using alignment pins, align the loose armature
drive disk to the alternator fan and attach to the
rotor drive hub with 8 bolts (3/8-16 x 1.25 in.) and
washers. Torque the bolts to 61.0 Nm (45 ft. lbs.).
See Figure 9-6.
