SCREW CONVEYOR ADAPTER ASSEMBLY
1.
Install seals (408) into adapter housing as shown in Figure
15. If the optional packing adapter is to be used, install only
one seal in the small end of the adapter. Use extreme care
when installing seals to avoid damage to the seals. Press or
tap seals into place by applying pressure only on the outer
edge of the seal. Make sure seals are install evenly and are
not tilted.
2.
If using the optional packing adapter, install the two studs
(413), retaining ring (412), and two nuts (414). Thread the
nuts onto the studs about 4–5 threads. Install the three
braided type seals (415) in a circular direction into the adapter
cavity. Shoulder the braided seals against the adjustable
retaining ring (412). To aid in installation of the driveshaft in
step 7, the braided seals can be flattened out slightly with a
soft hammer prior to installation. When installing the braided
seals offset the joints from each other.
3.
Lightly tap the large washer (407) into the counterbore on the
large end of the adapter to seal the braided material installed
in step 2 or the seal installed in step 1.
4.
Place reducer on blocks so that it lays flat with the input shaft
down.
5.
Position screw conveyor adapter (400) on the reducer output
hub so that the small end (end with four drilled holes) rests
on reducer. The approximate 3.0mm piloting projection
should locate in the output seal bore next to the auxiliary seal.
Adapter projection should not touch the face of the gear case
casting.
6.
Place four adapter screws (409) and lock washers (410)
through the adapter and thread into the reducer. Tighten the
four cap screws (409) to the torque specified in Table 11.
7.
Turn reducer onto its side. Use caution not to damage either
type seals and install driveshaft through the adapter housing
into the reducer. Line up the keyway in the driveshaft with the
keyway in the reducer hub bore. Slide or gently tap key into
reducer through the input shaft side of the output hub.
8.
Install the retaining ring (411) into the screw conveyor wedge
(402). Making sure the driveshaft is fully seated into the
reducer, slide the wedge onto driveshaft.
9.
Install keeper plate (401), support washer (416) (sizes
TA6307 and TA7315 only, driveshaft cap screw (404), and
lockwasher (405). Torque to specifications in Table 11.
DRIVESHAFT REMOVAL
To remove the driveshaft from the reducer, the following steps
are required.
1.
Remove the driveshaft retaining bolt (404) and lock washer
(405), the keeper plate (401), and the retaining ring (411).
2.
Referring to Table 9, install the correct size hex head
set screw into the end of the driveshaft until flush. Note
TA6307HM and TA7315HM does not require a set screw.
3.
Position the keeper plate (401) flush against the end of the
driveshaft and with the small end facing out. Next install the
retaining ring (411). When properly installed, the retaining ring
holds the keeper plate (401) in place.
4.
Screw removal bolt(s) into the keeper plate (401) and tighten
until the driveshaft wedge (402) is dislodged. Once the
driveshaft wedge (402) is dislodged, pull the assembly free
from the reducer. If installed, remove the hex head set screw
from the end of the driveshaft. The driveshaft can now be
easily removed from the reducer by pulling the driveshaft
straight out of the reducer.
NOTE: The removal bolt is not the same bolt as the retaining
bolt. Refer to Table 9 for the correct bolt to be used for removal.

REPLACEMENT OF PARTS
NOTE: Using tools normally found in a maintenance
department, a Dodge Torque-Arm II speed reducer can be
disassembled and reassembled by careful attention to the
instructions following.
Cleanliness is very important to prevent the introduction of dirt
into the bearings and other parts of the reducer. A tank of clean
solvent, an arbor press, and equipment for heating bearings and
gears (for shrinking these parts on shafts) should be available.
The oil seals are contact lip seals. Considerable care should be
used during disassembly and reassembly to avoid damage to the
surface on which the seals rub.
The keyseat in the input shaft, as well as any sharp edges on
the output hub should be covered with tape or paper before
disassembly or reassembly. Also, be careful to remove any
burrs or nicks on surfaces of the input shaft or output hub before
disassembly or reassembly.
