plete buildup of unit.
Unit Reassembly
1)
Install the secondary carrier assembly onto the output shaft;
aligning the splines of the carrier
(5)
with the output spindle
(3)
splines and centering the three threaded holes in the ouput
spindle between the planet gears. Once aligned slide the car-
rier onto the spindle.
2)
Install carrier retaining plate
(47)
& secure using provided 3/8-
24 Flathead capscrews
(48).
If using thread locking compound
to assist in screw retention, apply only a small amount to inter-
nal threads. Use of excess thread lock may cause screws to be
irremovable once compound has cured.
3) Lubricate
o-ring
(33)
and install on the ring gear
(7)
pilot.
Caution: Hold ring gear by outside diameter or use lifting device
to prevent injury.
4) Align the gear teeth of secondary ring gear
(7)
with
the gear teeth of the planet gears
(11)
and place
ring gear on base aligning mounting holes of ring
gear with holes in base. Use the scribed line made
during disassembly for reference. With carrier in place, install
secondary sun gear.
Simple Planetary Primary, for compound primary skip to step 5C
5S)
Install primary ring gear (with lubricated o-
ring in place), align mounting holes of ring gear
with holes in base using the scribed line made
during disassembly for reference. Install the primary carrier as-
sembly aligning gear teeth of ring gear with those of the planet
gears and place on base. Install the input gear
(17)
.
Compound primary (76:1 ratio and up):
5C)
a) The planet gears will now need to be timed. Refer to the
diagram appropriate for your unit’s gear ratio (at right). The
planet gears each have a timing mark, usually a round punch
mark stamped into the surface which is shown as a circle on
the diagram.
b) As seen from above, start with the top planet gear with
it’s timing mark pointing straight down. Next, rotate the
lower left planet gear counterclockwise as indicated in the
timing diagram. Then rotate the lower right planet gear
clockwise as indicated.
c) Set the input gear
(17)
and the input thrust race
(32)
into
the center of the primary planet carrier assembly.
d) If compound primary ring gear
(9)
was not removed dur-
ing disassembly, then skip to step 7. Otherwise, bolt to the
inside of the cover
(2)
with twelve bolts
(45)
. Use a remov-
able thread locking compound on the threads of the bolts
(45)
. Tighten to 110 ft.-lbs. dry or 80 ft.-lbs. lubricated.
e)
Install primary ring spacer
(10)
w/ O-ring
(33)
in place.
6)
Install the input to cover thrust washer
(32)
and carrier to cover
thrust washers
(31, 2ea; 30, 1ea)
Refer to exploded view for
details.
7)
Noting the scribed line made during disassembly, (with lubri-
cated o-ring in place) align and install the cover
(2)
.
8) Install and torque the 20 3/4-10 hex-head cap-
screws
(43)
with lockwashers
(46)
. The torque for the
cap-screws: 380 ft-lb dry, 280 ft-lb if the fasteners are lu-
bricated.
9)
Using a splined shaft to drive the input gear
(17)
ensure
that the unit spins freely.
10) Fill the unit to the proper level, as specified, with recom-
mended gear oil (refer to chart, page 3) after unit is sealed
with brake and/or motor.
The gearbox is now ready to use.The gear drive is now
ready to use.
