Assemble the Generator
Use standard torque specifications per Table 6 and Table 7 on pages
44-45 unless otherwise specified.
Install the Bearing Liners on the Drive-End of the Shaft:
1. Make sure the surfaces are clean. Apply STP® Oil Treatment
over the running surface on the shaft where the liner will sit.
2. Make sure the engraved numbers on the top and bottom halves
correspond and are on the same side. Mate the top liner over the
bottom liner on the shaft.
3. Put Loctite® Threadlocker Blue 242® on the split line screws,
insert the screws, and tighten.
Float In the Rotor:
1. Move the rotor up and in line with the stator. Fit a pipe over the
drive end of the rotor. Depending upon the space available, you
may have to use a pipe that can be disassembled, taking off an
additional piece during each stage of movement inward.
2. Attach slings around the pipe on one end and around the shaft on
the opposite end.
3. Lift up the rotor, and move it in, gently resting the rotor on the
stator as the slings are moved down the pipe.
Put a bead of premium siliconized acrylic latex caulk (or equivalent)
over the opposite-drive-end baffle mating surface, and install the
baffle.
Install the Liner Insulators:
Liner insulators are on the inside diameter of the top and bottom
bearing housing of both bearings. Each housing gets two insulators.
1. Fit up the insulators in the liner seat, and crease the outside edge
over the lip.
2. Trim the top of the insulators flush with the mating surface (of
the top and bottom halves of the housing).
3. Make sure the insulator surface is clean. Mix a Metallon two-part
epoxy in equal parts, and brush it over the track.
4. Peel the backing off, and put the insulators in place. Press them
tightly on the track, and place the liners (or fixtures) in the
housings to maintain good compression. Let the epoxy set for
12 hours. Make sure it has no voids and no air bubbles.
Install the Bottom Bearing Housings:
Before installing, brush Nox-Rust VCI-10 on frame mating surfaces
that will fit into bearing housing.
1. On the opposite-drive-end side, lift up the ends of the shaft
slightly, so the bearing housing clears the shaft, and bolt it in
place on the frame.
2. On the drive end side, lift the housing up and bolt it into place on
the frame.
CAUTION:
Ensure all components
are clean before assembly. Ensure all
gaskets have not deteriorated and are
positioned correctly.
NOTE:
If your unit has split roller bearings,
please consult your bearing manual that
came with your manual package.
CAUTION:
Make sure the pipe is
strong enough to support the weight of
the rotor and that it does not have rough
edges on the inside, which could damage
the shaft. To prevent tension on the shaft,
put slings around the largest shaft step
possible. Make sure the rotor does not hit
the stator.
CAUTION:
Ensure all components
are clean before assembly. Ensure all
gaskets have not deteriorated and are
positioned correctly.
NOTE:
Torque fasteners to the values
specified in Table 6 and Table 7 unless
otherwise specified.
CAUTION:
Carry out these
operations very carefully as to not
damage the shaft or bearing components.
CAUTION:
Remove all impurities
or other objects such as screws, nuts,
etc. from the bearing components. If
left inside, they could lead to bearing
damage. To prevent contamination, cover
the bearing components when they are
not being worked on.
NOTE:
If no fixture is available to compress
the insulators, use the top liner for both
halves of the bearing. Make sure all tubes
and fasteners are in the liner to ensure a
smooth surface.
