9. Press on the small end of the bearing cone (1D), being
careful not to contact the bearing cage, until the bear-
ing cone (1D) seats on the shoulder of the output shaft
(1A). Use Tool T145741.
10. Place the bearing cone (1F) onto the output shaft (1A).
11. Press or tap the bearing cone (1F) onto the output shaft
(1A) until it is just seated in the bearing cup (1E), while
rotating the housing (1G). Use Tool T144566. Ensure
there is end play on bearings.
12. Install the tanged flatwasher (1H) and lockwasher (1I) on
top of bearing cone.
13. Using a clean rag, clean the threads of the output shaft
(1A) and bearing nut (1J).
14. Apply Loctite 263 and place the bearing nut (1J) on the
output shaft (1A). (Fill the threads of the locknut (1J).)
15. Thread the bearing nut (1J) using locknut wrench
T151047 onto the output shaft (1A) down to top of Bear-
ing Cone.

17. Roll the housing (1G) in each direction to insure bearing
are seated and then measure housing initial rolling
torque using rolling torque adapter tool.
18. Tighten the bearing nut (1J) using locknut wrench
T151047. Torque the bearing nut (1J) approximately 155
ft-lbs (210 Nm), rotate the housing (1G) in both direc-
tions, and then torque the bearing nut to 155 ft-lbs. Roll
the housing in each direction then measure rolling
torque.
19. Repeat the step above until the housing rolling torque
increases 30-50 in-lbs (3.4-5.6 Nm) over the rolling
torque measurement in Step 17. Nut torque may be
more than 155 ft-lbs (210 Nm).
NOTE: Tighten the bearing nut to align the tang into nut slot. do
not loosen the bearing nut.
20. Bend the tang in lockwasher (1I) into the bearing nut
