TP-5936 7/0444 Section 9 Generator Disassembly/Reassembly
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.).
SeeFigure9-6.

5. Secure the alternator assembly to the engine
flywheel studs with washers, nuts, and spacers.
Torque the mounting nuts to 52.9 Nm (39 ft. lbs).
6. Secure the alternator side adapter to the engine
side alternator adapter with 12
bolts (3/8-16 x 2.5 in.) and washers. Torque the
mounting bolts to 52.9 Nm (39 ft. lbs.).
7. Reinstall the alternator fan guard using two spring
clips and screws.
8. Raise the alternator end of the generator set and
remove the wood block under the oil pan/flywheel
area. Lower the alternator.
9. Reinstall the vibromount mounting hardware (bolt,
large washer, two small washers, and locknut in
each vibromount). Tighten the mounting bolts to
28 Nm (20 ft. lbs.).
