Main Assembly
NOTE: All components should receive a generous amount
of lubricant oil as they are being assembled.
1. Place Housing-Spindle Sub-Assembly on the bench
with Spindle (1A) side down.
2. Place Output Carrier Sub-Assembly into Housing
(1E) and onto Spindle (1A).
3. Insert the larger diameter splined end of Input Shaft
(7) through bore of Output Carrier Sub Assembly
(4A) until shoulder of Input Shaft (7) contacts Thrust
Washer (4J) (See assembly drawing at back of man-
ual).
4. With the modified spline end facing up, place the
Output Sun Gear (8) into mesh with the planet gears
from the Output Carrier Sub-Assembly (4A).
5. Place Input Carrier Sub-Assembly (3A) onto Output
Sun Gear (8) splines.
6. Grease O-Ring (19) and insert into groove in Cover
Sub-Assembly (6).
7. Install Cover Sub-Assembly (6) onto Housing (1E)
and install twelve Bolts (14) into Cover (6). Torque
bolts to 70-80 in-lbs.
8. Attach ID Tag (15) onto unit. If Cover has knobs as
part of the cover, peen the top of each knob to form
a head to hold on the Tag. If the cover has no such
knobs, use drive screws.
9. Check disconnect, roll and leak check unit, leak
check brake, check brake release pressure.
