iv.
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:
i.
Lubricate seal (332) and O-ring (496) on thrust bearing housing (134A).
ii.
Carefully slide housing (134A) onto shaft (122) over thrust bearing.
iii.
Secure housing (134A) with thrust bearing snap ring (361).
b) Separate thrust (112D) and radial (112C) bearings on thrust end.
i.
Lubricate seal (332) and O-ring (496) on thrust bearing housing.
ii.
Carefully slide housing (134A) onto shaft and bearings until housing shoulder bottoms on
outer race of radial bearing (112C).
iii.
Install thrust bearing snap ring (361) into ring groove of housing.
iv.
With feeler gauge, measure clearance between snap ring (361) and outer race of thrust
bearing (112D). The clearance should be 0.010mm - 0.026mm | .004" - .010 at
G
gap.
v.
From the feeler gauge measurement, subtract .007. The resulting dimension is the thick-
ness of shims (331) at
S
gap.
vi.
Remove snap ring. Pull housing (134A) and install calculated shim pack (331) against hous-
ing shoulder. Reinstall housing and snap ring.
4.
Heat radial bearing (168C) in 82°C | 180º F oil bath. Slide radial bearing onto shaft (122) firmly
against shaft shoulder. Allow bearing to cool to room temperature before further assembly.
NOTICE:
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 adjust-
ing lugs on the frame and housing.
6.
Loosely install adjusting studs (356A) in adjusting lugs. Do not tighten.
7.
Install radial bearing slinger (123C).
