c) Install the inner race of one of the spherical roller
thrust bearing [3031] on the shaft. Use an induction
heater or hot oil bath to first heat the bearing (250
F recommended), press the bearing on the shaft
with the aid of a sleeve designed to push the inner
race only. Note that the bearing must remain
square to the shaft during assembly and that the
inner race must seat on the shaft shoulder.
d) Install the rollers and outer race onto installed inner
race.
e) Place the thrust bearing clamp ring [2542] on top of
the bearing installed.
f) Insert the springs [4260] into the holes provided in
the clamp ring.
g) Install the outer race of the second spherical roller
thrust bearing [3031] on top of the assembly. Place
spacer shims, 0.25mm (0.010 in.) between the
clamp ring and one of the bearing outer races.
Centralize the loosely assembled bearing
components. Using 2 c-clamps or similar devices
compress the springs in the clamp ring.
h) Install the remaining inner bearing race using the
same procedure as above.
i) Install the bearing spacer [2460].
j) Install the radial bearing.
k) Slide the bearing lock washers [6541] on the shaft
and fit the bearing locknut [3712]. Tighten the
locknut snugly and allow the bearings to cool.
Check the tightness. Before securing the
lockwasher tab, remove the spacer shims from the
clamp ring. Bend one tab on the lockwasher into a
slot in the locknut. Protect the bearings from
contamination.
l) Carefully install the lip seal [4300] in the thrust
bearing housing [3230] by pressing it squarely into
the bore. The primary sealing lip (spring loaded) on
seal should be installed facing the bearing. A small
amount of sealant may be applied on the O.D. of
the seal prior to its installation.
m) Lubricate the inside bore of the thrust bearing
housing [3230] and assemble it over the thrust
bearings. Care must be taken to prevent damage
of the seal on the shaft.
6.10.4 Frame assembly
6.10.4.1 Frame 1 & 2
a) Place the pedestal with the large flange flat on a
work surface/table.
b) Lift the bearing cartridge vertical and assemble to
the pedestal. Secure in position.
The orientation of the pedestal feet and the
tapped holes for the rear support foot should be
aligned.
c) Place the assembly so that the shaft when
installed will clear the table or work surface. The
assembly may be elevated if necessary.
d) Lift the shaft assembly into a vertical position (the
coupling end of the shaft is tapped for a lifting
bolt).
e) Lower it into the bearing frame [3130]. Note the
square head plug (or grease fitting in the thrust
bearing housing [3230] must align with the vent
lug [6580] in the frame [3130].
f) Install jacking and hold down hardware.
g) Place assembly horizontal and rest on pedestal
feet.
h) Install rear support foot for stability.
6.10.4.2 Frame 3& 4
a) Place the shaft assembly in a vertical position with
the thrust bearing housing [3230] resting on the
flange face and supported by blocks or clamps.
Access to one through hole in the thrust bearing
housing is required to attach one bolt.
b) Lift the bearing frame assembly [3130] vertically
and lower over the shaft assembly. Manually
guide the line bearing outer race into the bearing
frame bore. Note the square head plug (or grease
fitting in the thrust bearing housing [3230] must
align with the vent plug [6580] in the frame [3130].
c) Install at least one thrust bearing housing to
bearing frame hold down capscrews complete
with lockwasher to prevent the assembly from
coming apart when lifting.
d) Place the bearing frame assembly into a
horizontal position.
e) Install the remaining capscrews and lockwashers.
Assemble the jam nuts on the jacking screws and
assemble these into the thrust bearing housing
[3230].
f) Place pedestal on its feet.
g) Install cartridge assembly into the pedestal.
Secure with appropriate hardware.
i) Install rear support foot for stability.
