4. Use Loctite® 587 Blue to caulk the mating surface of the bottom
seal carrier (where it mates with the top half). Put gasket sealant
on the flange surface of the seal carrier where it will mate with
the bearing hanger. Also, put gasket sealant on the mating
surface of the bearing hanger.
5. Set the top half of the seal carrier over the seals. Make sure the
notch in the top of the seal lines up with the opening in the seal
carrier. Attach the bottom half of the seal. Put Loctite® 242 on
the threads of the two split line screws. Add a flat washer, insert,
and tighten.
6. Slide the seal carrier assembly up against the gasket and bearing
hanger. Bolt (with flat and lock washer) the seal carriers to the
bearing hanger, and tighten.
Install the air tube and oil supply lines.
Install the RTDs in the spring-loaded holders.
Before operating the generator, start the oil flow to the bearings, and
follow the startup procedure to ensure the bearing is functioning
properly and so that damage to the bearing doesn’t occur.
Brush Nox

ust on frame mating surface that will fit into the opposite-
drive end bracket (which fits over the top of the top bearing housing),
and attach the opposite-drive end bracket and tighten.
Attach the Exciter-PMG Frame-Stator:
1. Apply Nox-Rust to the machined surface on the bearing bracket
where the exciter-PMG frame-stator will mount.
2. Attach the exciter-PMG frame-stator to the bearing bracket
mounting surface.
3. Torque the bolts per Table 6 and Table 7 on pages 44-45.
Attach the Exciter Armature and Rectifier Tube
Assembly:
1. Brush Nox-Rust on the exposed PMG shaft journal.
2. Position the exciter armature-rotating rectifier assembly in line
with the shaft, and turn the assembly to the position where
the keyway in the exciter sleeve is in line with the key in the
generator shaft.
3. With hand force, push the armature assembly and rotating
rectifier tube over the shaft, so the end of the sleeve is against the
shoulder on the shaft. It may be necessary to tap lightly on the
exciter sleeve in order to move the assembly over the key. Use a
fiber or rubber mallet. If installation is still a problem, use a heat
gun to expand the exciter sleeve.
4. Connect the field leads to the rotating rectifier.
Attach the PMG:
1. Brush Nox-Rust on the exposed PMG shaft journal.
2. Put the armature key in the slot on the shaft.
3. Align the PMG rotor with the key on the shaft and holding by the
inside magnets, slide the PMG into position.
4. Install the PMG/Exciter armature retaining bolts. Torque the
bolts per Table 6 and Table 7.
