Penetrating oil (such as PB Blaster)
Torch

Safety Precautions: Prioritizing Your Well-being

Safety should always be the top priority when working on any home improvement project, and changing the shaft in your swamp cooler is no exception. Be sure to wear protective gear, such as gloves and safety glasses, to safeguard yourself from potential hazards.

Removing the Old Shaft: Overcoming Rust and Stubborn Fittings

Removing Collars and Bearings: Begin by using an allen key to remove any collars on the outer sides of the bearings. Next, loosen the bolts that hold the bearings in place.
Dealing with Rust: If the shaft is heavily rusted, apply a generous amount of penetrating oil, such as PB Blaster, and let it sit for a while to help loosen the rust.
Using a Torch: You can also try using a torch to heat up the shaft, which may help to break the bond between the shaft and the bearings.
Sawing the Shaft: If the shaft is still stuck, you can use a Sawzall blade to carefully cut down the middle of the shaft and then squeeze it out.

Installing the New Shaft: Aligning and Securing the Replacement

Cleaning the Area: Once the old shaft is removed, thoroughly clean the area to ensure that no debris or rust remains.
Inserting the New Shaft: Carefully insert the new shaft, making sure that it is aligned correctly with the bearings and other components.
Tightening the Bearings: Secure the bearings in place by tightening the bolts that hold them. Don’t forget to replace any collars on the outer sides of the bearings using the allen key.

Testing and Troubleshooting: Ensuring a Smooth Operation

After installing the new shaft, it’s essential to test the swamp cooler to ensure that it is functioning properly. Check for any leaks or unusual noises, and make any necessary adjustments to ensure a smooth operation.
