    Slide the old bearings off both ends of the drive shaft, and remove them from the evaporative cooler. Place the new bearings on the ends of the drive shaft, and secure the hold down brackets over the tops of the bearings with bolts.

    Beside above, how do you hook up a swamp cooler motor? How to Wire a Swamp Cooler Motor

  • Determine that the motor is 120-volt if intended for use in a normal household scenario.
  • Observe the manufacturer's instructions for connecting the wires to the terminals.
  • Connect the green wire to the ground in the 120-volt circuit.
  • Connect the red wire to the low fan speed in the control circuit.

    How To Replace A Swamp Cooler Motor Quick Overview

  • Remove the side panels on the swamp cooler.
  • Remove the motor belt.
  • Unplug the motor wiring.
  • Remove the bolts.
  • Remove the old motor.
  • Install the new motor.
  • Bolt the new motor into place.
  • Attach the belt and tighten it.

    • What size motor do I need for my swamp cooler?

    Evaporative cooler motors are relatively small in size, usually ranging from 1/3 to 1 horsepower. Most operate on 115/120 volts of power, which is the reason they use relatively little electricity when compared to 240-volt central air conditioning systems.

    How much does it cost to replace a swamp cooler motor?

    Swamp Cooler Repair Average Costs A spring service costs $150 to $200. Replacing a pump costs $225 to $275. Replacing a motor costs $500 to $600. Replacing pads can cost $125 to $500 depending on the pad type and quality.

    How do you remove a pulley without a puller?

    There is a way to do it. You put a wrench on the pulley bolt and block the other end against the floor or the frame. Then you use the starter motor to turn the engine (DO NOT START IT, JUST TURN IT) for at most one or two revolutions of the crank. Just enough to break the bolt loose.

    How do you remove a key from a motor shaft?

    The normal way to remove the key is to use a small cold chisel to impact the edge of the key in order to force it from its slot in the shaft. The exposed end of the key can be ground with a die grinder so that a "v" grove is formed in the end of the key.

    How do you remove a taper lock pulley?

    Removal of a Taper Lock bush, including Martin or Fenner Taper Lock bush components, is as follows:
  • Remove all screws, oil threads, and the point of the set screws or threads, under the head of the cap screws.
  • Insert screws into the holes that are threaded on the bushing side, as shown in Figure 2.

    • What is a motor sheave?

    A sheave (/?iːv/) or pulley wheel is a grooved wheel often used for holding a belt, wire rope, or rope and incorporated into a pulley. The sheave spins on an axle or bearing inside the frame of the pulley. Sheaves can be used to redirect a cable or rope, lift loads, and transmit power.

    How can I speed up my pulley?

    To increase blower speed, slightly loosen the setscrew that holds the pulley to the driveshaft. Move or turn the pulley clockwise on the shaft one turn, then tighten setscrew. If more speed is desired, turn the pulley clockwise two turns.

    How do I know what size pulley I need for my electric motor?

    There are complicated formulas for determining pulley ratios but in generic, layman terms, simply divide the driven component (pump) by RPM, the driver component (motor or engine) rated by RPM to get the required ratio. In the example below, the pump RPM is 1070, for full output, while the motor is 1750 RPM.

    How does changing pulley size affect speed?

    By changing the diameter of the pulley wheels, speed can be changed. A smaller pulley turning a larger pulley results in the larger one moving more slowly but with more shaft power.

    Why is my swamp cooler squeaking?

    The grease fittings on the top of the swamp cooler bearings require regular maintenance in order to prevent the bearings from drying out. When the bearings are getting dry you will hear a "chirping" or squeaking in the cooler as the blower fan turns.

    How tight should the belt be on a swamp cooler?

    The belt should be tight enough to turn the fan blades, but not so tight that it squeaks or squeals when the fan motor is engaged. The belt is too tight if it makes noise.

    Does a bigger drive pulley increase speed?

    Increasing Speed: When the powered pulley is larger than the non-powered pulley then the speed of the non-powered pulley is higher in proportion to the circumferences of the pulleys. The non-powered pulley will move slower but it will be able to generate twice as much torque.

    How long should I run the pump on my swamp cooler?

    depending on the size of the unit, put it on pump only first for 2-3 min., then put it on high cool, crack open 2 windows furthest from the unit and enjoy a nice cool house.

    Are swamp coolers noisy?

    Noise. Swamp coolers are much quieter in operation than air conditioners. This is because the condenser in the air conditioner produces noise as it converts the chemicals from liquid to gas.
