Installation (Continued)
Maximum
momentary or
starting torque is not to exceed
375% of 1/2 HP @ 1725 RPM for
applications involving four or
fewer starts per hour.
a. When connecting a load to the
speed reducer output shaft, care
should be taken to avoid
excessive tension when either belt
or chains with chain sprocket are
used. Overhung load should not
exceed limits shown in chart, at
1” from the oil seal. See Detailed
Overhung Load Calculations for
additional information.

Multiply pounds of load (obtained from
above formula) by the correct factor
listed below to determine actual
overhung load in “pounds” on center
of speed reducer output shaft.

Locate the center line of the sprocket,
pulley or gear as close to the oil seal as
practical to minimize overhung load
and increase bearing life.
b. On direct-coupled installations,
carefully check shaft and coupling
alignment as motor is being bolted
down, Shim as required. Do not
depend on a flexible coupling to
compensate for misalignment..

NOTE : Chart ratings are calculated at
Full Catalog Output Torque for 1/2 HP
input at 1725 RPM input. These ratings
are in addition to Full Catalog
Overhung Load assuming all worst
conditions of loading.
6. Make wiring connection. (Consult
nameplate on motor).
Maintenance
Make certain
that the power
supply is disconnected before
attempting to service or remove
any components! If the power
disconnect point is out-of sight,
lock it in the open position and tag
it to prevent unexpected
application of power
.
Cleaning
Properly selected and installed electric
motors are capable of operating for
long periods with minimal
maintenance. Periodically cleaning dirt
accumulations from open-type motors,
especially in and around vent openings,
preferably by vacuuming (avoids
embedding dirt in windings). At the
same time, check that electrical
connections are tight.
Lubrication
The Dayton speed reducer was filled
with oil at the factory to operate within
+25º to +125º F ambient temperature.
After 2000 hours of operation, drain
and refill with AGMA #4 gear oil. If
AGMA #4 gear oil is not available, use
multi-purpose gear oil SAE #90 for
ambient temperatures from +40º F to
+120º F. For temperatures below +40º F
use SAE #80 multipurpose gear oil.
