1. Oil output shaft and bearing cone. Using
cone press, press bearing cone onto end of
output shaft with retaining ring groove.
2. Stand hub on its small end. Using bearing
cup pressing tool press bearing cup down
into hub.
NOTE:
Make sure cup sits square with counterbore.
3. Turn hub over so it sit on large end. Using
bearing cup pressing tool press bearing cup
into small end of hub.
NOTE:
Make sure cup sits square with counterbore.
4. Place output shaft into hub so end of shaft with retaining ring groove points down.
5. Oil output shaft. Using seal pressing tool press seal into counterbore in small end of hub. The closed
face of the seal should be up.
6. Turn hub over so small end points down. Using bearing cone pressing tool, press bearing cone onto out-
put shaft. Rotate hub while pressing bearing. Stop pressing when hub starts to resist rotating.
7. Place spacer onto output shaft so it rests on top of bearing cone. Using retaining ring pliers, place retain-
ingringtomakesureitisseated.
8. Hit the end of output shaft once or twice with a soft face hammer. Turn the shaft in both clockwise and
counter clockwise directions while hitting. This will seat the bearing cone against the spacer and retain-
ing ring allowing necessary endplay in the hub-shaft sub-assembly.
9. Turn hub over so it rests on large end. Measure endplay in hub-shaft sub-assembly. Follow steps a-c.
a. Mount a dial indicator on hub. Locate the dial rod on top of output shaft.
b. Lift up on output shaft until the needle on the dial stops moving.
c. Read the dial. Reading should be no greater than 0,203 mm (.008 in.).
- If dial reads less than 0,203 mm (.008 in.), continue on to step 10.
- If dial reads more than.0,203 mm (.008 in.), repeat steps 8.-15. of “Torque Hub Assembly” on
page 2-23.
d. Remove spacer and replace it with thicker spacer (SK91 068570-011).
e. Repeat steps 6.-9. and remeasure end play (Figure ).
10. Apply a light coat of “Never Seize” to the pipe plugs and install into pipe plug holes in hub.
NOTE:
Leave hole for 90° fitting open.
