Cooler belt squeals, is worn out, damaged or otherwise
Tools / Materials (See Below for
A component of the evaporative / swamp cooler
that usually requires more service and replacement than any other
component is the cooler belt. A cooler belt that squeals, is
splitting or cracked, has already split completely apart or
otherwise is damaged requires replacement with a new cooler belt of
the same size. The following
are steps that you can follow in order to replace this old cooler
belt with a new one:
Caution: When dealing with any device that requires electrical
power, make sure you take precautions before you work on it,
including disconnecting the power.
If you have not
already done so in heeding the above cautionary statement, in
addition to turning off the power, unplug the plug of the cooler
motor, or, if the motor has no plug, disconnect its power wires
from the wires that are a part of the cooler, making sure you
note what was the arrangement of such wires before you
disconnect them for easy re-connections later on.
In order to
remove the cooler belt off of its pulley, the motor must be
loosened. To specifically do this, the motor mount--either
in bolt form, slide form, or pivot form--must be loosened; as
may be applicable, with the use of a fastener device (e.g., a
screwdriver), loosen the motor mount fasteners just enough so
that the motor, itself, can be pushed toward the pulley of the
blower house (which is really the center of the blower house) so
as to be able to pull the cooler belt off the pulley system
(i.e., two pulleys) with the increased "slack" of such a belt
created as a result of this pulling-forward action.
With the motor
mount still loosened and having the motor, itself, pulled toward
the pulley of the blower house just as before, install the new
cooler belt replacement by "looping" it around both pulleys, one
and then the other, and then pull the motor squarely back into
place on the motor mount, just barely hand-tightening the mount
actually tighten the motor mount fasteners as tight as possible
(even with a fastening device) for the relative future (until
another need to remove the motor arises), make sure the motor is
positioned into place on the motor mount just enough for the
belt, itself, to have about 1/2 to 3/4 of an inch of slack when
it is pulled on: If the belt slack is less than 1/2 of an
inch, pull the motor closer to the blower pulley until at least 1/2 of an
inch is met in belt slack; if the belt slack exceeds 3/4 of an
inch, pull the motor further away from the blower pulley. When you are
certain the cooler belt has about 1/2 to 3/4 of an inch of slack
when it is pulled on, you can now actually tighten the motor
mount fasteners as tight as possible (even with a fastening
device) for the relative future (until another need to remove
the motor arises).
Note: Steps 1-3 may not always be the efficient
way to remove an old cooler belt and have it replaced with a new one,
particularly when you have adjustable pulleys.
With an old cooler belt that has split completely (or if just
seriously cracked, can be cut to be replaced without waiting for an
all-out crack-split), all you have to do is simply pull it off--if
not already partially off because there is no circular band of
resistance, having been severed--and just install the new belt by
putting it on one of the pulleys and whirling this pulley and belt
in a circular fashion so as to have the rest of the belt easily loop
onto the other pulley with your hand's guidance.
Take the plug of the cooler
motor and plug it into the receptacle for its use or otherwise
make the necessary power wire connections of the cord with those
of the cooler electrical output, as may be applicable.
That's what you do to maintain a cooler
with a good-working cooler belt.
