Perform the following steps without interruption. Once the thread
locking compound is applied, you have only a few minutes before
the curing process will influence the bearing lock nut torque.
12. Install the bearing lock nut:
A. Apply high strength thread locking compound (Loctite 263 or equivalent)
and install the lock nut.
B. Tighten the lock nut to 150 N·m (110 ft−lb).
C. Rotate the housing on the spindle a few revolutions to align the bearings.
D. Tighten the lock nut to 200 N·m (150 ft−lb).
E. Rotate the housing on the spindle a few revolutions to seat the bearings.
If installing the bearing nut with the spindle installed on machine,
have an assistant hold the housing firmly in position during the
following step.
F. Loosen the lock nut completely, then tighten to 122 N·m (90 ft−lb).
Continue to tighten the lock nut until it aligns with one of the
locking washer tabs. Do Not loosen the lock nut to align it with
the locking washer tabs.
G. Secure the lock nut by bending one of the locking washer tabs into a
slot in the lock nut.
13. Install secondary carrier and primary carrier making sure that carrier gear
teeth align with ring gear and spline on spindle shaft.
14. If primary gear (item 25) was removed from drive shaft, slide gear onto shaft
and secure with retaining rings.
15. Install drive shaft assembly (items 24−26) making sure that drive shaft spline
aligns with carrier gears.
16. Cover the outer face of the thrust plate with grease and fit thrust plate onto
end cap. Make sure that thrust plate tabs are captive in end cap.
17. Apply a light coat of grease to a new O−ring and install it in the ring gear
bore. Avoid pinching or cutting the O−ring and install the end cap. Use a
soft mallet to fully seat the end cap.
18. Secure the end cap with the retaining ring. Make sure the retaining ring is
fully seated in the ring groove.
