These instructions must be read thoroughly before installation or operation. This instruction manual was accurate at the time of
printing. Please see www.baldor.com for updated instruction manuals.
WARNING: Because of the possible danger to person(s) or
property from accidents which may result from the improper
use of products, it is important that correct procedures be
followed. Products must be used in accordance with the
engineering information specified in the catalog. Proper
installation, maintenance and operation procedures must
be observed. The instructions in the instruction manuals
must be followed. Inspections should be made as necessary
to assure safe operation under prevailing conditions. Proper
guards and other suitable safety devices or procedures, as
may be desirable, or as may be specified in safety codes
should be provided, and are neither provided by Baldor
Electric Company, nor are the responsibility of Baldor
Electric Company. This unit and its associated equipment
must be installed, adjusted and maintained by qualified
personnel who are familiar with the construction and
operation of all equipment in the system and the potential
hazards involved. When risks to persons or property may
be involved, a holding device must be an integral part of the
driven equipment beyond the speed reducer output shaft.
INSTALLATION
1. If applicable, remove the plastic plugs that protect the
threaded holes in the sides of the reducer housing and
install the lifting brackets supplied with the reducer.
2. Determine the running position of the reducer (Figure 1). Note
that the reducer housing has been machined for pipe plugs
around the sides of the reducer for horizontal applications
and in each face for vertical applications. The plugs must be
arranged relative to the running position as follows:
Horizontal Installations
- Install the magnetic drain plug in
the hole closest to the bottom of the reducer. Throw away
the tape that covers the filter/ ventilation plug in shipment
and install plug in topmost hole. Of the remaining plugs on
the sides of the reducer, the lowest one is the minimum oil
level plug.
Vertical Installations
-Install the filter/ventilation plug in the
hole provided in the top face of the reducer housing. Use the
hole in the bottom face for the magnetic drain plug. Of the
remaining holes on the sides of the reducer, use a plug in the
upper housing half for the minimum oil level plug.
The running position of the reducer in a horizontal application
is not limited to the four position shown in Figure 1. However,
if running position is over 20
°
in position “B” and “D” or
5
°
in position “A” and “C” either way from sketches, the oil
level plug cannot be safely used to check the oil level, unless
during the checking the torque arm is disconnected and the
reducer is swung to within 20
°
for position “B” or “D” or 5
°
for position “A” or “C” of the positions shown in Figure 1.
Because of the many possible positions of the reducer, it
may be necessary or desirable to make special adaptations
using the lubrication fitting holes furnished along with other
standard pipe fittings, stand pipes and oil level gauges as
required.

CAUTION: Unit is shipped without oil. Add proper amount
of recommended lubricant before operating. Failure to
observe these precautions could result in damage to, or
destruction of, the equipment.
NOTE:
TXT12, TDT13 and TDT14:
Refer to instruction manual
packed with tapered bushings for installation then go to step 9.
TDT15 only:
3. Place the inboard bushing on the shaft and position it 3½”
away from the bearing.
4. Place output hub key on shaft and in bushing. Stake key in
position.
5. Hoist reducer into position and slide it onto shaft aligning
hub keyway with key.
6. Align unthreaded holes of inboard bushing with threaded
holes of bushing back-up plate. If necessary, rotate the
bushing back-up plate to align holes. Insert screws and
tighten lightly.
7. Place the outboard bushing in position on the shaft aligning
the bushing keyway with the key. Align the unthreaded
holes in the bushing with the threaded holes in the back-up
plate, rotating the back-up plate if necessary. Insert bushing
screws and tighten lightly.
8. Tighten the screws in both bushings alternately and evenly
to 1600 inch-pounds wrench torque.
