Overgreasing can be a cause of bearing and
motor failure. Make sure dirt and contaminants
are not introduced when adding grease.
CAUTION
!
5.10 MOTOR LUBRICATION
The induction-type squirrel cage motors have antifriction
ball or roller bearings front and rear. At periodic intervals
they require relubrication.
NOTICE: 50 Hz TEFC motors have sealed bearings
that do not require relubrication.
Relubrication Interval
(or 9 months, whichever comes first)
1000 hours............................all 60 Hz TEFC drive motors
2000 hours ............................ all 60 Hz ODP drive motors
and all fan motors
Improper lubrication can be a cause of motor bearing
failure. The quantity of grease added should be carefully
controlled. The smaller motors must be greased with a
lesser amount of grease than larger motors.
When regreasing, stop motor. Disconnect power; lock out
and tag. Remove outlet plugs (or spring-loaded grease
relief plugs if present). The outlet plug may not be
accessible on the fan end of some TEFC motors.
Grease should be added when the motor
is stopped and power disconnected.

5.9-2 Water Cooled Coolers (Continued)
Cleaning
The interior tube surfaces can be cleaned by several
methods. Flushing a high velocity stream of water
through the tubes will remove many forms of deposits.
More severe deposits may require running wire brushes
or rods through the tubes. Also, rubber plugs can be
forced through the tubes if a special air or water gun is
available for this procedure.
A qualified cleaning service should be used for the
cleaning process. These organizations can evaluate the
type of deposit to be removed and supply the
appropriate solution and method for a complete cleaning
job.
Precautions
When re-installing bonnets to cooler shell, tighten bolts
uniformly in a cross-pattern. Overtightening can result in
cracking of bonnet.
Cleaning solutions must be compatible with metallurgy
of cooler.
Care must be taken to avoid damaging tubes if
mechanical cleaning procedure is used.
* No greasing required (permanently lubricated bearings)
