7. Remove all gear end bearing carrier to housing screws (50, 51) and lockwashers (55). With four
jack screws in tapped holes in the carrier flange, FIGURE 6-7, pull the carrier. This also pulls
bearings from the rotor shaft. Tighten jack screws evenly to prevent binding carrier on dowel pins
and bearings. Support the carrier so it does not drop and damage shaft extensions. When the
carrier is free, remove the bearing retainers (10, 11), bearings (31, 32), lip type oil seal (87, 88)
and shaft seals (18, 19). If the bearings are to be used, handle with care.
Do not use a torch to heat the pinion to aid in removal. The pinion can be damaged by
concentrated heat.
NOTICE
Never reuse shaft seals that have
been in operation. Refer to
“Rotor
Shaft Seal,” page 29.
8. Remove the discharge end carrier cover (14), oil slinger (6), bearing locknut (33, 34), and
lockwashers (35, 36), bearing clamp plates (11, 12) and bearing clamp plate shims (94).
See FIGURE 6-8.
9. Rig the adapter plates (shown in FIGURE 6-1 and FIGURE 6-2), and the puller shown in FIGURE
6-9, and press the rotor shaft through the bearing. Use a shaft protector. Be sure the bolts
holding the plate are threaded into the tapped holes of the bearing housing far enough to prevent
stripping of the threads, and evenly adjusted so the plate is square with the shaft. Press one
rotor through the bearing at a time, then proceed to Step 10.
