16) Install motor
(15)
with gasket
(14D)
, using hex head cap
screws
(12c)
and torque bolts to 55 ft-lbs.
The auger Drive iS noW reaDY for uSe.
*
nal end of output shaft. Press bearing on slowly until it is just
seated against bearing cup
(11D)
. With a slight press load still
applied, rotate base
(1)
by hand to ensure roller bearings are
rotating evenly and smoothly. Inner bearing cone
(11c)
may
require additional press load to reach proper bearing preload.
If roller bearings are seated properly, continue on to set and
check bearing preload.
ShafT bearing PreloaD: Proper shaft bearing preload is
achieved when torque required to rotate base is 50 to 80 in-
lbs. This rolling torque is equal to a force of approximately 11
to 18 lbs if pulling on base flange to rotate base (1). This may
be determined by feel or by using a fish scale or similar mea-
suring device to check rolling torque.
8)
Install shims
(14a)
over internal end of output shaft
(2)
. Shims
should slide all the way down to outer bearing cone
(11c)
,
where they will rest. The same number (quantity) of shims
removed from unit during disassembly should be returned.
Follow shims with split ring segments
(14c)
. Segments will
sit directly on top of bearing shims.
noTe: Quantity of shims (14a) may vary from unit to unit.
bearing preload, set at the factory, determines quantity of
shims.
9)
Install the locking ring
(14b)
onto output shaft.
10) Lightly grease a new o-ring
(10a)
and install it into o-ring
groove in base
(1)
. Assemble ring gear
(8)
to base
(1)
. Re-
fer back to scribe marks made across external joints of gear
drive prior to Disassembly Procedure. Line up scribe marks
between ring gear and base to give
correct hole alignment.
noTe: be certain that o-ring (10a) stays seated in groove
during Step 10.
11) Install secondary carrier assembly into unit. Carrier assembly
should be installed with hub side down
(24 tooth spline)
.
Rotate carrier assembly back and forth to mesh secondary
planet gear teeth
(7)
with ring gear
(8)
teeth. Once teeth
mesh, let secondary carrier slide down until it contacts with
output shaft spline. The carrier splined hub
should spline onto
output shaft. Carrier hub will rest on top of locking ring
(14b)
when splines are fully engaged.
12) Install the carrier cup washer
(9b)
.
Single stage: Install input gear
(4)
, input thrust washer
(9a)
.
Double Stage: Install secondary sun gear
(6)
primary car-
rier assembly
(5)
input gear
(4)
, and input
thrust washer
(9a)
.
13) Grease a new o-ring
(10a)
and install it into bottom of cover/
bail assembly
(3)
. Refer back to scribe marks made across
external joints prior to Disassembly Procedure. Line up scribe
marks between cover/bail assembly and ring gear
(8)
so that
orientation of motor mount holes and oil plug are back to their
original positions.
noTe: be certain o-ring (10a) stays seated in cover/bail
assembly during Step 13.
14) Install all twelve of the 7/16 lockwashers
(12b)
and the 7/16
hex capscrews
(12a)
and torque to 70 ft-lbs.
15) Fill unit with oil per the capacity and lubricant recommenda-
tions posted on page 4.
