2.10.4.4. Heat the bearing sleeve (25) to 175°-200°F. Check the temperature
and then insert a new rotor bearing into the sleeve. Be sure to place
the bearing into the sleeve with the wide shoulder of the outer race
against the shoulder of the bearing sleeve also make sure the punch
mark is facing upwards on the inter race. Install the bearing and sleeve
on shaft as shown in assembly drawing (Figure 2.5).
2.10.4.5. Install the rotor end oil slinger (19). Use the slinger to tap the
bearing and sleeve down on the shaft.
2.10.4.6. Install a new bearing self-locking nut (47) using bearing locknut
torque wrench adapter, torque to 400 ft. lbs.
2.10.4.7. Place the drive end oil slinger (20) on the shaft as shown in
assembly drawing (figure 2.5).
2.10.4.8. Heat a new thrust bearing (12) to 150°-175°F. Check the
temperature with a heat stick. Place the bearing on the shaft with the
wide shoulder of the inner race against the oil slinger (20).
2.10.4.9. Install the inner spacer of the matched pair of bearing spacers (23).
2.10.4.10. For Model RO-A: Place the outer spacer of the matched pair of
bearing spacers (23) on the thrust bearing. Heat a new radial bearing
(13A) to 150°-175°F. Check the temperature with a heat stick. Then
place it on the shaft against the inner bearing spacer with the wide face
of the inner race facing away from the bearing spacer.
2.10.4.11. For Model RO-B: Heat the inner race of a new roller bearing (13B)
to 150°-175°F. Check the temperature with a heat stick. Then place it
on the shaft against the inner bearing spacer.
2.10.4.12. For Model RO-B Only: Install the outer race of the roller bearing
(13B) in the pedestal bore against the bearing cap (14) Fig. 2.4. Place
the outer spacer of the matched pair (23) of bearing spacers on the
outer race of the roller bearing.
NOTE: Check to see if oil slinger (20) will rotate freely after bearings are
installed. If oil slinger (20) rotates freely, place the shaft sleeve (28),
bearing cap slinger (27) and the used bearing locknut (46) back onto
the shaft. Tighten locknut using the bearing locknut torque wrench
adaptor until the oil slinger (20) is secured. Do not exceed 175 ft. lbs.
(237 NM).
2.10.4.13. Position the two oiler rings (22) in pedestal (17) so that the shaft will
pass through them when the rotor assemble is installed.
2.10.5. Rotor Assembly installation
