WARNING
THIS REDUCER IS SHIPPED DRY. OIL
MUST BE ADDED BEFORE OPERATION. SEE TABLE 4
FOR LUBRICATION SPECIFICATION.
SAFETY
Rotary equipment is dangerous unless adequately
guarded. The user is responsible for complying with all
applicable safety regulations. Adequate safety
instructions must be given by the user to personnel
directly responsible for the installation, maintenance, and
operation of the equipment. The gear unit must not be
operated above its service rating.
WARNING
DAMAGE IN SHIPMENT
Inspect the unit immediately upon receipt of shipment for
any signs of rough handling or damage. Any evidence of
this should be reported immediately to the carrier and a
claim entered. This may show up as scuffed paint, broken
or cracked casting, bend shafts, metal deformation or a
shift in alignment of components.
STORAGE
All units are tested before shipment with a rust inhibiting
type of oil which covers interior surfaces. Shaft
extensions are coated with drying film rust preventive.
This will provide protection of the units for normal periods
during installation. Depending upon the severity of
storage conditions, the protection could range from a few
months for unprotected outside storage, to a year or so
for temperature controlled indoor storage.
LONG TERM STORAGE
For positive long term storage protection, it is
recommended that the following procedures be followed:
REDUCER INTERIOR
1. For protection, fill the reducer completely with the
same oil that will be used in operation.
2. Remove breather at top of reducer and insert pipe
plug.
3. At the end of the storage period the oil should be
drained out and filled to the proper level with the type
of lubricant specified for operating the reducer. The
breather should be remounted now.
REDUCER EXTERIOR
All exposed unpainted parts such as shafts should be
coated thoroughly with a corrosion preventive compound,
solvent cut back type, leaving a firm film. Use Nox Rust
No. 369 (Daubert Chemical Co.) or equivalent.
GENERAL
1. The input shaft of every reducer should be rotated
once a month enough turns to produce one complete
turn on the output shaft. This will prevent Water Etching
or False Brinelling of the bearings and seizure of the
elastomeric seal lip material on the shaft.
2. Certain storage areas, such as an outside location
close to salt water, can be quite severe. Under these
circumstances, a periodic inspection of the equipment
is recommended and retreatment applied if required.
3. For best protection, the equipment should be stored in
a climate controlled building to minimize the effects of
sun, moisture, wind, and airborne abrasive material.
4. If the equipment is stored outside, it should be
protected with a tarpaulin. Optionally, units can be
encapsulated in a polyethylene bag. This cover must
be air tight and include a container of calcium chloride
crystals to absorb moisture. To be effective, the
crystals would need to be replaced at regular intervals.
NOTE the change in oil level plug locations for output
speed below 30 rpm shown in figure 3 for double
reduction units and figure 5 for single reduction units.
Numbered items are as follows:
1
Bushing and Breather
2

3
Magnetic Drain Plug
5. An occasional break in the paint coating causing rust
spots may occur during outdoor storage. These spots
should be cleaned and touched up with paint before
placing the equipment in service.

6. Before start up after storage, the unit should be
checked carefully for any rust accumulation on gears
or bearings, or on shafts in the seal areas. Oil seal
leakage may result due to seal deterioration or cutting
of the seal lip from rust accumulation on the shaft.
Bearing cover and housing bolts should be checked to
be sure they are tight.

MOTOR LOCATION
The allowable 10° (0.17 radians) variation in mounting
location does not apply to the mounting positions with the
hollow shaft vertical (E and F). For vertical shaft
operation with greater angular variation, factory oil level
modifications are required.
The belt tension for the shaft mount is adjusted with the
turnbuckle in the torque arm or by movement of the motor
platform on the optional piggyback motor mount.
For units without a piggyback motor mount, the V-belt
drive may be located in any convenient position
regardless of the location of the torque arm. The most
common location, however, is shown in figure 7 [90°
(1.57 radians)] to a line between the input and output
shafts. This location permits control of belt tension with a
minimum adjustment of the torque arm turnbuckle.

GENERAL
SHEAVES AND BELTS
When sheaves are furnished with reducers, they are
generally mounted at the factory.
In mounting these items, the center of the load should be
located no farther out than one shaft diameter away from
the bearing cover. Otherwise, excessive overhung
loading could exist resulting in early failures to bearings,
shafts and gearing. Refer to Table 2 for applicable
minimum sheave diameters.
The driver and driven sheaves should
aligned. A straight edge laid across the
sheaves will aid in installation. The straight
lay evenly across both sheaves with no
figure 9.
If sheaves are to be mounted in the field, extreme care
should be used. It is quite easy to damage internal
members by heavy blows used in sheave mounting.
Select a sheave bore to give a tapping or light driving fit.
If necessary, the sheave bore should be enlarged to
provide this class of fit. If a press fit is required, we
suggest the sheave be heated to expand the bore before
installation. Heating above 250° F (121° C) is not
recommended due to possible damage of the oil seal by
heat conduction through the shaft.

For safety, purchaser or user should
provide protective guards over shaft extensions, and any
sheaves and belts mounted thereon. Failure to do so may
result in bodily injury and/or damage to equipment.
BACKSTOP REMOVAL
BACKSTOP INSTALLATION AND MAINTENANCE–
DOUBLE REDUCTION 8107 – 8407 AND 8415H25
If the backstop cannot be easily removed from the
housing, it may be necessary to remove the retaining ring
and use the retaining ring grove with a suitable puller to
extract the backstop from the housing bore.
WARNING
Removal of the backstop is basically the reverse of the
assembly procedure.
BACKSTOP INSTALLATION
1. Remove the four screws from the cover plate opposite
the input shaft extension side of the reducer.
2. Insert key in backstop keyway. Leave about 0.25” (6.4
mm) of key in keyway with the greater length of the key
extending outside the end face of the backstop.
3. Where applicable, install the retainer ring on the backstop before inserting into the housing.
4. Lubricate the end of the shaft before inserting backstop. DO NOT USE AN ANTI-SEIZE COMPOUND AS
LUBRICANT.
5. Position backstop over input shaft so the arrow (etched
in backstop) points in the same direction as motor rotation. See figure 10.
Figure 11
Note: In sizes 8107 through 8407 and 8415H25, the gear
oil also lubricates the backstop.
WARNING
If a backstop fails, the input shaft should
also be replaced as it probably was damaged during the
failure process.
WARNING
WHEN A BACKSTOP IS USED WITH THE
REDUCER, DO NOT USE LUBRICANTS OF THE EP
TYPE (EXTREME PRESSURE CHARACTERISTICS),
OR THOSE CONTAINING SLIPPERY ADDITIVES.
BACKSTOP MAINTENANCE – DOUBLE REDUCTION
8415H15
Figure 10
For this unit size, an external backstop is used. The
manufacturer does not recommend repair in the field, nor
attempting to change direction of rotation in the field. In
either case, the backstop should be returned to the
factory.
6. Turn the input shaft with one hand in the normal
direction of the rotation while inserting the backstop in
the housing. The key should be aligned with the keyway in the housing now and the backstop should move
in easily. When installing the backstop, do not apply
pressure to the side plates of the backstop. Drive only
on the outer race. See figure 11. The backstop should
be positioned with the retaining ring flush against the
housing.
BACKSTOP OIL FILLING PROCEDURE
1. Remove plugs A and B as shown in figure 12 and add
oil through A until oil flows from B. See backstop lubricant
chart, table 3, for proper lubricant.
CAUTION
7. Test the direction of rotation to make certain the
installation is correct.
If reducer is mounted at an angle in any
plane, consult factory for proper backstop lubricant levels.
8. Where applicable, install the grease plate and replace
the gasket and cover plate. Tighten the screws to
prevent leakage.
2. Install both plugs and tighten to prevent leakage. Plugs
consists of a button head screw and leather washer. Be
sure washer is in place.

12 to 24 hours per day operation. For extremely dusty
or dirty operating conditions, it may be
necessary to change oil at more frequent intervals to
keep oil clean. When oil becomes contaminated or
oxidized (dark colored), the backstop should be
flushed and oil changed.

BACKSTOP DISASSEMBLY
1. To take off the backstop, drain oil from the backstop
and remove backstop cap by unscrewing cap screws,
holding it to the backstop body. Remove the retaining
ring. The backstop and torque arm can be pulled off by
prying between the torque arm and the housing, or by
use of a gear puller. The manufacturer does not
recommend repair in the field, nor attempting to
change direction of rotation in the field. In either case,
the backstop should be returned to the factory.

not use carbon tetrachloride.
CAUTION
Reducers used in high humidity
conditions, such as waste-water treatment plants, or
subject to large temperature variations will incur internal
moisture condensation. Pressure relief breathers are
recommended for these type of applications. Oil analysis
should also be performed frequently to check for water
contamination.
BACKSTOP ASSEMBLY
1. IMPORTANT: Before replacing the backstop, coat thoroughly the shaft surface under the backstop, the shaft
keyway, the backstop bore and its keyway, and the key
with room temperature vulcanizing sealant (RTV)
General Electric RTV-102 or Permatex No. 2.
1. Check oil level daily. (See “Maintenance checkpoints”.)
2. Add oil, if necessary, to the proper fluid level.
3. Flushing is recommended every six months for up to
6
This is to prevent oil leakage from the reservoir back
along the shaft.
6. Place left lockwasher and left locknut on taper bushing.
Turn left locknut until contact is made between the
lockwasher and the end of the reducer hollow shaft.
Tighten left locknut until all play is removed in the
tapered portion of the bushing.
2. Balance of reassembly is reverse of disassembly.
Check torque arm for free movement. It must not bind
against the bearing cap or cap screws.
LUBRICATION
3. Fill backstop to indicated level with proper oil. See
Backstop Lubricant chart table 3.
THIS REDUCER IS SHIPPED DRY. OIL
MUST BE ADDED BEFORE OPERATION. SEE TABLE 4
FOR LUBRICATION SPECIFICATIONS.
WARNING
REDUCER MOUNTING INSTRUCTIONS
NOTE: Do NOT use an anti-seize compound on any of
the assembled components.
The oil used should be a high quality product, having
rust and oxidation inhibitors, anti-foaming agent, a high
viscosity index (preferability above 90) and a low acid
content. It should be neutral in reaction, free from girt or
abrasives and non-corrosive to gears or bearings.
1. Clean driven shaft to remove any contaminants. Dry
thoroughly.
CAUTION
2. Screw on right locknut on the large end of the taper
bushing. Turn nut until all threads on nut are engaged
on bushing.
IMPORTANT: WHEN A BACKSTOP IS
FURNISHED WITH THE REDUCER, DO NOT USE
LUBRICANTS OF THE EP TYPE, (EXTREME PRESSURE CHARACTERISTICS), OR THOSE CONTAINING
SLIPPERY ADDITIVES.
3. Slide bushing, lock nut end first, onto driven shaft.
Locate bushing as close as possible to the driven shaft
bearing support and above keyway in driven shaft. See
figure 13.
CAUTION
LOW TEMPERATURE OPERATION
The pour point of the oil should, at minimum, be equal to
the lowest ambient starting temperature. For best results,
the pour point should be 5 to 10 degrees F (2.8 to 5.6
degrees C) below the lowest ambient starting temperature.
For reducers operating in ambient temperature
conditions below 15° F (-9.4° C) special lubrication is
required. Refer to factory for recommendations, giving
expected ambient temperature and operating cycle.
CAUTION
Figure 13
4. Place key in bushing into driven shaft keyway.
HIGH TEMPERATURE OPERATION
When ambient temperatures exceed 125° F (51.6° C)
special lubrication, special oil seals, and/or increased
cooling of the reducer may be required. Refer to factory for
recommendations, giving expected ambient temperature
and operating cycle.
5. Slide Shaft Mount Reducer over driven shaft and up onto
the taper bushing. DO NOT HAMMER ON THE CASE
OR INPUT SHAFT. A lead hammer or a soft punch may
be used to tap against the end of the HOLLOW SHAFT.
Press firmly on hollow shaft of reducer to make sure
taper is fully engaged. See figure 14.
CAUTION
HIGH SPEED OPERATION
When input speed exceeds 1800 rpm, special lubrication,
and increased cooling of the reducer may be required.
Refer to factory for recommendations, giving expected
ambient temperature and operating cycle.
CHANGE CYCLE
The first oil change should be made after two weeks, or
100 hours of operation. After this, we recommend
changing reducer oil every 2500 hours or six months,
whichever occurs first. Consider seasonal temperature
changes when changing oil. Operating conditions can
vary this guide line. Abnormal temperatures and
contamination can seriously affect the lubricant causing

and could be harmful.
early sludging, oxidation, and acid formation. Under
these conditions, a sample of the lubricant should be
submitted to the petroleum supplier at periodic intervals.
This will establish a change cycle which will provide for
renewal of the oil before its degradation.
CAUTION
In the Food (including animal food) and
Drug Industry, consult the petroleum supplier for
recommendation of lubricants which are acceptable to
the Food and Drug Administrations and/or other
authoritative bodies having jurisdiction.

Verify the rating of the reducer (indicated on the
nameplate and certified print) to be sure that service
rating, RPM or speed range, thermal rating, and any
overhung or thrust loading are not exceeded in actual
operation. If input speed exceeds 1800 rpm, refer to
factory for operation and lubrication recommendations.
5 EP
Where the lubricant contains Lead Naphthenate (an EP
additive) the reducer oil sump temperature should not
exceed 160° F (70° C).
1. Make sure reducer is filled with correct lubricant to the
proper level. Refer to the section of this bulletin on
lubrication and/or the nameplate affixed to the reducer.
CAUTION
Always fill the speed reducer to the oil level
indicator for proper lubrication.
2. Check for free rotation of all elements. In many cases,
the input shaft of the reducer can be turned by hand
even with a connected load.
CAUTION
When a backstop is furnished with the
reducer, do not use lubricants of the EP type, (Extreme
Pressure Characteristics), or those containing slippery
additives.
3. Check all bolts and cap screws to make sure they are
tight.
4. Check belts for proper tension and alignment.
CAUTION
Table 5 oil capacities are only an
approximation and should not be used as the exact value
for an oil fill. See figures 2 -5 for location of the oil plug, oil
drain, and breather for the six different mounting positions.
WARNING After energizing motive power, if any
undue noise occurs, shut off power IMMEDIATELY.
5. Observe temperature rise. This may take up to four
hours to stabilize. In some instances the temperature
in the oil sump may rise as much as 100° F (38° C)
above the ambient. Actual operating temperature will
vary slightly with the reducer size, ratio, type, and operating conditions.

CAUTION
Under no circumstances should the oil
bath temperature exceed 200° F (93° C). If this should
occur, consult the factory. The housing and the shaft next
to the high speed seal may show temperature
significantly above 200° F (93° C). This will diminish as
the seal and shaft sealing area wear in. Application of oil
at this area during the break-in period will aid this
process. Bearings can produce localized heating from
cramping, either radial or axially. Check for insufficient
end play. Many times the reducer temperature is judged
by the touch of a hand and may be considered to be quite
hot. The only positive method is to use a surface
temperature measuring instrument or by using a
thermometer directly in the oil bath.
FOOD AND DRUG INDUSTRY
Some operations in the Food and Drug Industry require
special lubrication considerations in view of possible

approximate frequency and if it is at accurate regular
intervals.
WARNING
Do not operate this unit beyond its
service rating as any resulting failure could cause
damage to property or life and limb.
5. LUBRICANT CONDITION A change of color in the oil
or thickening or unexplainable corrosion of internal
parts is an indication that the lubricant has deteriorated
and should be changed.
The system of connected rotating parts
must be free from critical speed, torsional or other type of
vibration, no matter how induced. The responsibility for
this system analysis lies with the purchaser of the speed
reducer.
CAUTION
6. LOADING Periodic load checks are valuable in making
sure that the reducer rating is not exceeded.
7. OIL BREATHER Must be kept clean.

8. VIBRATION A change in the vibration normally
associated with the system can indicate worn parts.
Each unit is equipped with a breather. This should be
cleaned at intervals to insure that it is working properly.
9. DIRT ACCUMULATION Any undue accumulation of
dirt on the reducer or in fan components where fans
are used will affect proper cooling of the unit.
MAINTENANCE CHECK POINTS
For optimum protection and preventive maintenance,
inspect the reducer daily. Points to cover are:
10. GREASE PURGE For units equipped with an
optional grease purged sealing system, lubricate
once per week with a high quality Lithium base
grease NLGI number 2 consistency.
1. OIL LEAKAGE at oil seal, housing split, bearing cap
shims, and pipe fittings. Tighten housing bolts, bearing
cap bolts and pipe fittings and/or replace oil seal if
leakage is sufficient to cause rapid drop in oil level. It
may be necessary to add sealant between bearing cap
shim packs and the housing, or at the housing split.
OIL SEALS
All oil seals used in these units are dual lip type, and have
a synthetic elastomer lip material. They are
provided with a spring back of the inner lip which exerts
constant pressure and keeps the lip in contact with the
shaft.
Some units are equipped with an optional grease purged
sealing system for use in areas subjected to a
considerable accumulation of external foreign matter.
This consists of an exterior shroud covering the oil seal
and a grease fitting.
2. OIL LEVEL Any undue drop in oil level is a sign of oil
leakage from some point on the reducer and should be
corrected. The oil level should be checked when the
reducer is not running.
3. TEMPERATURE Check the actual temperature of the
oil bath, gear case, and shafts at various points. This
should be done after the unit has been in operation at
least two hours. The average oil bath temperature is
140° F (60° C) however, the range can vary from 100°
F to 200° F (38° C to 93° C). Bearings can produce
localized heating from cramping either radial or axial.
Check for insufficient end play. Any undue rise in
temperature above that normally encountered and not
accountable for by a rise in the ambient should be
investigated. Low oil level, abnormal loading, thickening
of lubricant, and bearing seizure are possible sources. If
a particular bearing is a heat source, the housing area
adjacent to the bearing would warm up.
In any disassembly of the reducer or removal of bearing
caps, it is recommended that all oil seals be replaced.
CHANGING SEALS
1. If the unit is sheave driven, the driven sheave must be
removed to gain access to the oil seal on the input
shaft. To change oil seals on the output shaft, remove
reducer from the driven shaft. See REDUCER
REMOVAL for further information.
2. Remove grease shroud, if so equipped, from cover.
Drill two holes in the seal face 180° (3.14 radians)
apart. Insert large sheet metal screws and leave about
0.18 inches (4.76 mm) length of screw under the screw
head exposed. Use a pry bar with the notch at one end
under the screw heat to lift the seal out. See figure 15.
4. SOUND LEVEL A sudden change in the sound level
is a possible indication of low oil level undue thinning
out of lubricant, abnormal loading, or deterioration of
internal parts.
Noise is usually difficult to isolate because sound can
travel throughout an entire drive system. A noise can

along the exposed edge.
8. For those units having the optional grease purged sealing
system, remount the shroud and add a high quality
Lithium base grease of NLGI number 2 consistency.

3. Take care not to damage the seal bore in the bearing
cap or the shaft surface when removing the old seal.
4. Examine the new oil seal for cuts or imperfections in the
lip. The lip should have a smooth and uninterrupted
edge with no flashes from molding. The outside
diameter of the seal should be free from scratches and
burrs. Test the seal for grip on the shaft upon which it
has to run; it should not be loose but should offer some
drag to axial movement. If the seal is not satisfactory,
discard it and try another one.

5. Clean the bearing cap seal bore and remove any burrs;
coat the cap bore and the seal outside diameter with an
adhesive sealant such as General Electric RTV-102 or
Permatex No. 2.

Figure 16
6. The shaft in the seal areas should be examined for
score marks, scratching or grooving. First try polishing
out the imperfections with a fine grade of emery cloth
(No. 240). The polishing motion should not be axial or
spiral in direction but circumferential. If the shaft
surface can not be reconditioned sufficiently by
polishing to remove all imperfections, it may be
possible to shift the seal position sufficiently to escape
this area. The inner lip with the spring in back of it is the
important one to consider. The alternative is to metalize
the shaft and re-grind to a surface finish of 10 to 20
RMS. If the surface imperfections are not too deep, a
simple plunge grind to no more than 0.010” (0.254 mm)
undersize on the diameter may clean up the shaft. In
fact, plunge grinding is preferable to polishing to remove
any chance of spiral marks on the shaft which can cause
oil leakage. A third option is to use a wear sleeve.
Consult the manufacturer for installation instructions.
1. Remove left locknut and lockwasher from taper
bushing mounted on driven shaft. See figure 13.
2. Tighten right locknut until contact is made with the
reducer hollow output shaft. Continue turning this
locknut until the reducer is pushed clear of the tapered
portion of the bushing.
3. Remove the reducer off the driven shaft. Unit should be
properly supported during this procedure.
7. Wrap 0.005” (.127 mm) plastic shim stock around the
shaft to cover up the keyway and any shoulders. Wipe
oil or grease on the seal lip to ease assembly. Slip the
seal on the shaft up to the bearing cap with the lip and
spring facing in toward the reducer. Using the end of a
piece of wood about 1 by 2” (25 by 50 mm), drive the
seal in tapping first on one side then the other. See
figure 16. The seal should be flush with the bearing cap
outer face and square with the shaft. Remove the shim
stock. If steel or brass shim stock is used, make sure
all burrs on the edge are removed to avoid cutting the

2. Removing the hex cap screws will permit the removal
of the housing cover. Housing cover must be removed
straight up to prevent damage to dowel pins. See
figure 17.
3. After all cap screws are removed, two can be inserted
in the tapped holes in the housing cover flange and
used as jack screws to aid in cover removal.
See figure 18.
Figure 21
CLEANING
All parts, including the housing, should be washed
thoroughly with kerosene or a mineral solvent. Any
accumulation of sludge deposits or corrosion should be
removed. Do not use a wire brush on any seal, bearing,
or gear tooth surfaces to avoid scratching. All old sealant
should be scrapped from mating flange surfaces of the
housing and bearing caps.
Figure 18
4. Bearings and gears are now fully accessible, ready for
removal. See figure 19.
5. Remove exposed high speed bearings. All other
bearings and/or gears are now easily removable as a
unit (bearings, gear, and shaft). When removing a
bearing cone from a shaft, a small press may be used,
supporting the shaft assembly on the cone shoulder.
Keep the bearings clean.
Figure 22
REASSEMBLY
1. Reassembly is basically the reverse of the disassembly
procedure.
2. Install new oil seals in the high speed and low speed
open end bearings caps as discussed in CHANGING
OIL SEALS.
Figure 19
6. Tapered roller bearing cups can be removed from the
housing and cover bores using pry bars. See figure 21.
3. Bearing cones may be heated to ease assembly.This can
be done with an infra-red lamp, a heated oil bath, or an
oven. If an oil bath or oven is used, take care to support
the bearing well off the bottom and away from the sides
of the container to avoid direct contact with an area of
localized heat from the heating element or the flame.
7. Figure 22 shows a typical disassembled unit with all
components.
8. The oil seals are a press fit in the bores. They can be
drawn out readily. Use a piece of wood preferably, to avoid
damaging the seal bore surfaces in the bearing cap.
Do not exceed 250° F (121° C) to
prevent drawing back the bearing hardness.
WARNING
11
If heating facilities are not available, it will be necessary to use a press. In pushing the cone on the shaft
make sure that no pressure is exerted on the cage or
rollers, only on the cone shoulder and that the cone
seats flush with the shaft shoulder. Before pressing on
the shaft, check the shaft shoulder for burrs or dirt.
Remove them if present, otherwise the bearing will
not seat squarely. Apply anti-seize compound to the
bearing seat before pressing. In supporting the shaft
to press on a bearing, make certain that the point of
support is on the shaft end and not on the cage and
rollers.

4. The shafts with bearings and gears installed along with
the bearing caps and shim packs should be placed back
in the housing in the reverse order of disassembly. Coat
bearings with a thin film of oil before assembly into the
housing. A sealant such as General Electric RTV-102 or
Permatex No. 2 should be applied to the housing split
and to the bearing cap flanges.
.002 Preload / .002” Endplay
.051 / .102 mm
Check endplay by placing a dial indicator pointer on
shaft end and wedge shaft to its extreme opposite
positions. See figure 24. The total dial variation is the
shaft endplay. If the endplay does not agree with the
specification above, correct it by adding or removing
shims as required. Add shims to increase endplay,
remove shims to decrease endplay. Rotate shafts each
time shims are added.
5. All bearing caps should be mounted with their original
shim packs in position. In mounting the open end caps
with oil seals, take care not to damage the seals. Wrap
0.005” (0.127 mm) plastic shim stock around the shaft
over the keyway and/or shaft shoulder to protect the
seal lip. Do this gently to prevent dislocating the spring
back of the lip. The housing bolts should be tightened
before the bearing cap bolts. This should be done
evenly to prevent warping the housing. See Figure 23,
Table 6 for bolt torque values. Note that the maximum
torque values are shown. Use 90% to 100% of these
values.

7. After completion of assembly, turn the input shaft by
hand until the output shaft has made at least one
complete revolution. There should be no undue drag at
this point. If any gearing has been replaced, check to
make sure that each set has backlash.
Figure 23
6. Bearing Adjustment. All reducers have tapered roller
bearings and required a specific axial endplay for each
size. Rotate the input shaft until the output shaft has
made at least two full turns. This is to seat the rollers. Use
the following endplays for each shaft bearing set-up.
Before start-up, fill reducer with oil and follow instructions
listed under OPERATION. New bearings and oil seals
may tend to run slightly warmer during break-in. If the
reducer, for ease of repair, has been removed from its
operating location recheck alignment of sheaves and
tension on bolts. After one month of operation, it is
advisable to recheck all bolts for tightness.

.051 / .102 mm
Check endplay by placing a dial indicator pointer on the
hollow shaft end and wedge shaft to its extreme opposite
positions. See figure 24. The total dial variation is the
shaft endplay. If the endplay does not agree with the
specification above, correct it by adding or removing
shims as required. Add shims to increase endplay,
remove shims to decrease endplay. Rotate shafts
each time shims are added.
3. Examine the new oil seal to be mounted in the adaptor
for the hollow shaft for cuts or imperfections in the lip.
The lip should have a smooth and uninterrupted edge
with no flashes from molding. The outside diameter of
the seal should be free from scratches and burrs. Test
the seal for grip on the shaft upon which it has to run; it
should not be loose but should offer some drag to axial
movement. If the seal is not satisfactory, discard it and
try another one.
After changing shims, recheck endplay.
Plastic or metal shims are used in original assembly.
Use no substitutes.
4. Clean the adaptor rear seal bore and remove any
burrs; coat the bore and the seal outside diameter with
an adhesive sealant such as General Electric RTV-102
or Permatex No. 2.
9. If the unit is equipped with the optional packing gland,
install the bolts holding the packing gland in place
and mount the packing gland on the adaptor. Load
the packing material inside the rear spacer and place
it in the front bore of the adaptor. Mount the front
spacer between the packing gland and the rear spacer.
5. The shaft in the seal areas should be examined for
score marks, scratching or grooving. First try polishing
out the imperfections with a fine grade of emery cloth
(No. 240). The polishing motion should not be axial or
spiral in direction but circumferential. If the shaft
surface can not be reconditioned sufficiently by
polishing to remove all imperfections, it may be
possible to shift the seal position sufficiently to escape
this area. The inner lip with the spring in back of it is the
important one to consider. The alternative is to metalize the shaft and re-grind to a surface finish of 10 to 20

shaft. In fact, plunge grinding is preferable to
polishing to remove any chance of spiral marks on the
shaft which can cause oil leakage. A third option is to
use a wear sleeve. Consult the manufacturer for
installation instructions.
10. If the unit is not equipped with packing gland, install
the adaptor oil seal inside the bore of the adaptor.
11. Examine the new oil seal to be mounted in the adaptor
for the drive shaft for cuts or imperfections in the lip.
The lip should have a smooth and uninterrupted edge
with no flashes from molding. The outside diameter of
the seal should be free from scratches and burrs. Test
the seal for grip on the drive shaft; it should not be
loose but should offer some drag to axial movement. If
the seal is not satisfactory, discard it and try another
one.
