3. Install outboard bearing (112A) on shaft (122)
(Fig. 75).
d
NOTE: Regreaseabie bearing has a single
shield. The outboard bearing is installed w!th
shield toward impeller.
NOTE: There are several methods used to
install bearings. The recommended method is
to use an induction heater that heats as we!! as
dem.agnet!zes the bearings.
Wear insulated gloves when using a beating
heater. Bearings will get hot and can cause
physica! injury.
4. Place lo&washer (382) on shaft (122). Place tang of
lockwasher in keyway of shaft
5. Thread locknut (136) onto shaft (122). Tighten
locknut until snug. Bend any tang of lockwasher
into a slot of locknut.
NOTE: 77ghten locknut if necessary to align the
.
closest tab of lo&washer with slot on lo&rut.
6. Place bearing retaining ring (361 A) over shaft (122),
-,
flat side facing bearing.
7. Install inboard bearing (168A) on shaft (122).
NOTE: Regreaseabie bearing has a sin ie
~_ shield.. The inboard bearing is instaile B
with
shieid away from impeller.
NOTE: There are several methods used to
install bearings, Ttre recommended method is
to use an induction heater that heats as we!! as
demagnetizes the bearings.
Wear insulated gloves when using a beartng
heater. Bearings will get hot and can cause
physica! iniury.
NOTE: Coat internal surfaces of bearings with
