7. Press or pull thrust bearing arrangement from shaft
(122). For double row ball thrust bearing (112C), apply
pulling force to inside race only. For two-bearing
thrust arrangement, apply pulling force to inside race
of thrust bearing (112D). The thrust bearing (112D),
thrust bearing collar (237), and radial bearing (112C)
will be removed.
8. Do not remove radial bearing retainer (119B) from
bearing frame (228). A factory press fit insures a
permanent installation.
TO ASSEMBLE THE “J” BEARING
1. The shaft (122), thrust bearing housing (134A) and
bearings must be clean and free of burrs.
2. To assemble thrust bearing arrangement:
a. Double row ball thrust bearing: (1J-4J)
1) Heat thrust bearing (112C) in 180º F oil
bath.
2) Slide thrust bearing (112C) onto shaft (122)
firmly against shaft shoulder.
3) Install lockwasher (382) and locknut (136)
before bearing cools. When bearing cools to
room temperature, retighten locknut and
secure lockwasher tang.
b. Separate thrust (112C) and radial (112D) bearings
on thrust end (5J):
1) Heat thrust bearing (112D) in 180º F oil
bath and install on shaft (122) firmly
against shaft shoulder.
2) Heat thrust bearing collar (237) in oil bath
and install shaft against inner thrust bearing
inner race.
3 Heat radial bearing (112C) in oil bath and
install on shaft with inner race against
thrust collar (237).
4) Install lockwasher (382) and locknut (136)
before bearings cool. When bearings cool to
room temperature, retighten locknut and
secure with lockwasher tang.
3. To install thrust bearing housing (134A):
a. Double row ball thrust bearing:
1) Lubricate seal (332) and O-ring (496) on
thrust bearing housing (134A).
2) Carefully slide housing (134A) onto shaft
(122) over thrust bearing.
3 Secure housing (134A) with thrust bearing
snap ring (361).
b. Separate thrust (112D) and radial (112C) bearings
on thrust end:
1) Lubricate seal (332) and O-ring (496) on
thrust bearing housing.
2) Carefully slide housing (134A) onto shaft
and bearings until housing shoulder
bottoms on outer race of radial bearing
(112C).
3) Install thrust bearing snap ring (361) into
ring groove of housing.
4) With feeler gauge, measure clearance
between snap ring (361) and outer race of
thrust bearing (112D). The clearance
should be .004 - .010 at “G” gap.
5) From the feeler gauge measurement,
subtract .007”. The resulting dimension is
the thickness of shims (331) at “S” gap.
6) Remove snap ring. Pull housing (134A)
and install calculated shim pack (331)
against housing shoulder. Reinstall housing
and snap ring.
4. Heat radial bearing (168C) in 180º F oil bath. Slide
radial bearing onto shaft (122) firmly against shaft
shoulder. Allow bearing to cool to room temperature
before further assembly.
NOTE: Radial retainer permanently pressed into
bearing frame (228) at factory.
5. Lubricate seal 332 in radial bearing retainer (119B).
Carefully insert the shaft/bearing assembly into the
bearing frame (228) from the drive end. Guide the
threaded end of the shaft through seal (332) in retainer
(119B). As the thrust bearing housing (134A) enters
the bearing frame bore, align adjusting lugs on the
frame and housing.
6. Loosely install adjusting studs (356A) in adjusting
lugs. Do not tighten.
7. Install radial bearing slinger (123C).
