Standard Lip Type Seal – Assembly
1. Place adapter on a work bench with the large trough end
facing up.
2. Place seal in adapter so that spring faces out. Seal should be
tapped evenly into place in the adapter with a small hammer,
applying force only on the outer corner of the seal. Fill cavity
between lips of seal with grease.
3. Install seal retainer ring by tapping with a hammer.
4. Move to "Adapter To Reducer – Assembly" section.
Optional Adjustable Packing Adapter – Assembly
1. Place adapter on a work bench with the large trough end
facing up.
2. Install the two threaded studs from the trough end, using a
at head screwdriver in the slotted end of the studs. Install the
studs just far enough to allow the packing retainer ange to
clear the top of the studs on the opposite side.
3. For some smaller sizes, it may be necessary to place the
adapter into place before running the studs down, and install
the packing kit from the trough side, and then the keeper
plate.
4. Install the retainer ring by tapping evenly with a hammer.
5. Flip over the adapter, placing the larger trough end down on
the work bench.
6. Compress and install one braided seal into the machined
bore of the adapter. Continue with the other two braided
seals, osetting the joints.
7. Install the packing retainer, placing the machined shoulder
against the braided seals.
8. Install the nuts hand tight. Do not tighten these nuts with a
tool until the driveshaft has been installed.
9. See Figure 2 for assembly view with nomenclature.
10. Move to "Adapter To Reducer – Assembly" section.
Adapter To Reducer – Assembly
1. Carefully place the reducer on its side in order to install the
adapter to the reducer.
2. Taking into consideration the nal orientation of the gearbox,
install the adapter with one opening in the downward position.
3. Align the small end of the adapter against the machined
surface of the reducer.
4. Install the four bolts with washers and tighten them to the
torque rating specied in Table 5.
5. Position the driveshaft with key, leading with the end that is
drilled and tapped for the retaining bolt.
6. Install the driveshaft though the adapter and into the gearbox,
aligning the key in the driveshaft keyway with the keyway in
the output hub of the reducer.
NOTE: Be extremely careful when sliding adapter section
of shaft through seal to prevent seal lips from being
damaged or rolled over.
7. Install the shaft retainer, lock washer and bolt, and tighten to
the torque rating specied in Table 5.
8. If using the optional adjustable packing adapter, hand-tighten
the nuts on the packing retainer then rotate one additional
turn with the appropriate tool. Once in operation, these nuts
can be retightened if the braided seals wear during normal
operation. Braided seals can be replaced as needed.
INSTALLATION
1. Use lifting bracket where applicable to lift reducer.
2. Determine the running positions of the reducer (see Figure 3).
Note that the reducer is supplied with six plugs; four around
the sides for horizontal installations and one on each face for
vertical installations. These plugs must be arranged relative
to the running positions as follows:
Horizontal Installations – Install the magnetic drain plug in
the hole closest to the bottom of the reducer. Install the lter/
ventilation plug in topmost hole. Of the two remaining plugs
on the sides of the reducer, the lowest one is the minimum oil
level plug.
Vertical Installations – Install the lter/ventilation plug in
the hole provided in the upper face of the reducer housing as
installed. If space is restricted on the upper face, install the
vent in the highest hole on the side of the reducer per Figure
3 using the optional vertical vent kit. Install a plug in the hole
in the bottom face of the reducer. Do not use this hole for
the magnetic drain plug. Install the magnetic drain plug in
the lowest hole on the sides of the reducer. Of the remaining
holes on the sides of the reducer, use the plug in the upper
housing half for the minimum oil level plug.

FIGURE 3- MOUNTING POSITIONS
Figure 3 - Mounting Positions

3MN16042
Below 15 RPM output speed, oil level must be adjusted to
reach the highest oil level plug. If reducer position is to vary
from those shown in Figure 3, either more or less oil may be
required. Consult Dodge.
The running position of the reducer in a horizontal application
is not limited to the four positions shown in Figure 3. However,
if running position is over 20° in position B and D or over 5°
in position A and C—either way from sketches—the oil level
plug cannot be used safely to check the oil level, unless the
reducer is swung to within 20° for position A and C or within
5° for position B and D of the positions shown in Figure 3.
Because of the many possible positions of the reducer, it
may be necessary or desirable to make special adaptations
using the lubrication lling holes furnished along with other
standard pipe ttings, stand pipes and oil level gauges as
required.
NOTE: If motor mount, motor, and sheaves are to be
installed on reducer before mounting screw conveyor
drive to trough end, bypass step 3; perform steps 4 and 5,
and then return to step 2.
3. Use lifting tab to hoist screw conveyor drive into position.
Slide shaft into screw and adapter over trough end studs.
Only one set of adapter holes will t over the trough end
studs. If the mounted position of the screw conveyor drive
varies more than 15° from any of the four horizontal mounting
positions shown in Figure 3, an incorrect set of holes has
been selected for coupling adapter to reducer. This can
be corrected by removing adapter screws and rotating the
reducer to its proper position. Reinstall and tighten adapter
screws to torque specied in Table 5. Install lockwashers and
tighten nuts on trough end studs. Attach drive shaft to screw.
4. Motor Mount Installation
The motor mount must be installed on the reducer as shown
in Figure 4.
Remove the required housing bolts on the side of the
reducer. Place the motor mount brackets in position and
install the longer housing bolts supplied with the motor
mount assembly. Do not fully tighten the housing bolts at this
time.
Install the bottom plate to the motor mount brackets and
tighten with the hardware provided. Next, tighten the housing
bolts to the torque values listed in Table 5.
Install the four adjusting studs to the bottom plate using
the jam nuts provided and securely tighten. These nuts will
not require any further adjustment. Add one additional jam
nut to each stud and thread approximately to the middle of
the stud. Install the top motor plate on top of the jam nuts.
Assemble the remaining jam nuts on studs to secure top
motor plate. Do not fully tighten these nuts yet.
Mount motor, drive and driven sheaves, and V-belts.
NOTE: Mount driven sheave as close to the reducer
housing as practical.
Adjust V-belts to the proper tension by adjusting the jam nuts
and securely tighten.
Check all bolts to ensure that they are securely tightened.
5. Install sheave on input shaft as close to reducer as practical.
CAUTION: Unit is shipped without oil. Add proper amount
of recommended lubricant before operating. Failure to
observe this precaution could result in damage to or
destruction of the equipment.
6. Fill gear reducer with the recommended volume of lubricant
per Table 1.
LUBRICATION
IMPORTANT: Because Torque-Arm reducers are shipped
without oil, it is extremely important to add the proper
amount of lubricant prior to operating reducer. For most
applications a high-grade petroleum-base rust and oxidation
inhibited (R&O) gear oil is suitable. Under severe conditions
EP-type oils can be used. See Table 1 for proper oil volume
and viscosity requirement.
Follow instructions on reducer warning tags.
Lubrication is very important for satisfactory operation. The
proper oil level must be maintained at all times. Frequent
inspection, at least monthly, with the unit not running and
allowing sucient time for the oil to cool and the entrapped air
to settle out of the oil should be made by removing the level plug
and verifying the level is being maintained. If oil level is low, add
the proper lubricant until the oil volume is increased to the correct
level.
After an initial operation of about two weeks, the oil should be
changed. If desired, this oil may be ltered and reused. After
the initial break in period, under average industrial operating
conditions, the lubricant should be changed every 2,500 hours
of operation. At every oil change, drain reducer and ush with
kerosene, clean magnetic drain plug and rell to proper level with
new lubricant.
Under extreme operating conditions, such as rapid rise and fall
of temperature, dust, dirt, chemical particles, chemical fumes, or
oil sump temperatures above 200°F, the oil should be changed
every one to three months, depending on severity of conditions.
CAUTION: Too much oil will cause overheating and too little
will result in gear failure. Check oil level regularly. Failure to
observe this caution could result in bodily injury.
Heating is a natural characteristic of enclosed gearing. A
maximum gear case temperature approaching 200°F is
not uncommon for some units operating in normal ambient
temperatures of 80°F. When operating at the rated capacity with
proper lubrication, no damage will result from this temperature.

GUIDELINES FOR (H)SCXT REDUCER
LONG-TERM STORAGE
During periods of long storage, or when waiting for delivery or
installation of other equipment, special care should be taken to
protect a gear reducer to have it ready to be in the best condition
when placed into service.
By taking special precautions, problems such as seal leakage
and reducer failure due to lack of lubrication, improper lubrication
quantity, or contamination can be avoided. The following
precautions will protect gear reducers during periods of extended
storage:
Preparation
1. Drain oil from the unit. Add a vapor phase corrosion inhibiting
oil (VCI-105 oil by Daubert Chemical Co.) in accordance with
Table 3.
2. Seal the unit airtight. Replace the vent plug with a standard
pipe plug and wire the vent to the unit.
3. Cover all unpainted exterior parts with a waxy rust
preventative compound that will keep oxygen away from the
bare metal (Non-Rust X-110 by Daubert Chemical Co. or
equivalent).
4. The instruction manuals and lubrication tags are paper and
must be kept dry. Either remove these documents and store
them inside, or cover the unit with a durable waterproof cover
which can keep moisture away.
5. Protect reducer from dust, moisture, and other contaminants
by storing the unit in a dry area.
6. In damp environments, the reducer should be packed inside
a moisture-proof container or an envelope of polyethylene
containing a desiccant material. If the reducer is to be stored
outdoors, cover the entire exterior with a rust preventative.
When Placing the Reducer into Service
1. Fill the unit to the proper oil level using a recommended
lubricant. The VCI oil will not aect the new lubricant.
2. Clean the shaft extensions with petroleum solvents.
3. Assemble the vent plug into the proper hole.
Follow the installation instructions provided in this manual.

REPLACEMENT OF PARTS
IMPORTANT: Using tools normally found in a maintenance
department, a Dodge (H)SCXT 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.
Ordering Parts: When ordering parts for reducer, specify
reducer size number, reducer model number, part name, part
number, and quantity.
It is strongly recommended that, when a pinion or gear is
replaced, the mating pinion or gear is replaced as well. If the large
gear on the output hub must be replaced, it is recommended
that an output hub assembly consisting of a gear assembled
on a hub be ordered to ensure undamaged surfaces on the
output hub where the output seals rub. However, if it is desired
to use the old output hub, press the gear and bearing o and
examine the rubbing surface under the oil seal carefully for
possible scratching or other damage resulting from the pressing
operation. To prevent oil leakage at the shaft oil seals, the smooth
surface of the output hub must not be damaged.
If any parts must be pressed from a shaft or from the output hub,
this should be done before ordering parts to make sure that none
of the bearings or other parts are damaged in removal. Do not
press against rollers or cage of any bearing.
Because old shaft oil seals may be damaged in disassembly, it is
advisable to order replacements for these parts.
Removing Screw Conveyor Drive from Trough End
Disconnect an electrical power to the drive. Drain lubricant from
reducer. Uncouple drive shaft and screw. Remove nuts from
trough end studs. Support drive by means of hoist and carefully
pull unit away from trough end to slide drive shaft out of screw.
Disassembly
1. Remove retainer bolt, lockwasher, and shaft retainer from
drive shaft. Pull drive shaft out of reducer from adapter side.
Remove adapter.
2. Position the reducer on its side and remove all housing
bolts. Drive dowel pins from housing. Using the three pry
slots around the periphery of the ange, gently separate the
housing halves. Open housing evenly to prevent damage to
the parts inside.
3. Lift input shaft, all gear assemblies, and bearing assemblies
from housing.
4. Remove seals from housing.
5. Remove bearings from shafts and hubs. Be careful not to
scratch or damage any assembly or seal area during bearing
removal. The hub assembly can be disassembled for gear
replacement but if scratching or grooving occurs on the hub,
seal leakage will occur and the hub will need to be replaced.
Reassembly
1. Output Hub Assembly: Heat gear to 325°F to 350°F to
shrink onto hub. Heat bearings to 270°F to 290°F to shrink
onto hub. Any damage to the hub surfaces where the oil seals
rub will cause leakage, making it necessary to replace the
hub.
2. Input Shaft Assembly: Heat bearings 270°F to 290°F to
shrink onto shaft. Press bearings on shaft.
3. Drive the two dowel pins into place in the right-hand housing
half (backstop side).
4. Place right-hand housing half on blocks to allow for protruding
end of output hub.
5. Install all bearing cups in right-hand housing half, making sure
they are properly seated.
6. Mesh the output hub gear and input shaft assembly together
and set in place in housing. Make sure bearing rollers (cones)

7MN16042
are properly seated in their cups. Set bearing cups for left-
hand housing half in place on their rollers.
7. Make sure both housing halves are clean and free of
RTV residue. For (H)SCXT 505E through 705E, apply a
continuous 1/8” diameter bead of Dow Corning RTV732
sealant on the ange surface of the right-hand housing (make
sure RTV is placed around all bolt holes). Do not apply RTV
sealant to (H)SCXT 305E and 405E reducers at this time. Set
the left-hand housing half in position onto the dowel pins and
gently tap with a soft hammer until housing bolts can be used
to draw housing halves together. Make sure reducer shafts do
not bind when tightening housing bolts. Torque housing bolts
per torque values listed in Table 5.
8. For (H)SCXT sizes 305E and 405E, rotate the input shaft and
set all bearings with a soft hammer. Using a magnetic base
and indicator, measure and record the endplay of the input
shaft and output hub. Remove the left housing half and shim
behind the bearing cup as required to achieve the correct
bearing endplay per Table 4. Repeat this process and check
endplay until proper endplay is obtained.
9. For (H)SCXT sizes 505E through 705E, install the output
seal carrier and draw down with two bolts 180° apart to 50
inch-pounds of torque. Loosen both bolts then retighten
nger-tight only. Measure the clearance between the housing
and carrier ange at each bolt and average the two values.
Add 0.010” to the average reading and make up shim pack.
Install shim pack between the carrier ange and reducer
housing. Torque the bolts to the value shown in Table 6. Using
a magnetic base and dial indicator, check the axial endplay
reading of the output hub is per Table 4.
10. For (H)SCXT 305E and 405E reducers, follow assembly
instructions for housing halves, including sealant, then
continue to step 11. For (H)SCXT 505E through 705E
reducers, repeat step 9 for installing and adjusting the input
bearings. Adjust the axial endplay per Table 4 then continue
to step 10.
11. Install input and output seals. Lightly coat the seal lips
with Mobilith AW2 All-Purpose grease or equivalent. The
possibility of damage and consequent oil leakage can be
decreased by covering all sharp edges with tape prior to seal
installation. Seals should be pressed or tapped with a soft
hammer evenly into place in the reducer housing, applying
pressure only on the outer edge of the seals.
NOTE: Extreme care should be used when installing
seals to avoid damage due to contact with sharp edges
on the input shaft or output hub. A slight oil leak at the
seals may be evident during initial running but should
disappear unless seals have been damaged.
12. Install backstop cover. Make sure all bolts, if applicable, are
tightened to the correct torque values listed in Table 5.
