If you are planning to replace the shaft;
if your able to loosen the 2 square headed bolts( which must be done to allow for shaft movement) do so, then after bearings and pulley are off emerycloth (smooth no burrs or rust) the shafts 2 ends and get grinder and cut thru the shaft on the inside of squirrel cage area as close to the edge of cage as possible drive the shortened pieces of the shaft inward( oil this pieces to help ease movement thru blower wheel) until they are removed replace shaft with new shaft and re-install parts and or replace as needed bearings and blower wheel. I am getting ready to do this very job myself ( take measurements of shaft on each side to ensure your back where you started when done)

The solution is to install "up ducts" These devices are easy to install and are fairly cheap. With a swamp cooler the best way to use them is to allow them to draft outside with the "up duct" you get the drafting to the outside but also get to remove attic heat too.

Check for plugged holes in the top water distribution tray where the water from the pump exits to wet the pads.

If you can get to the whole water trough to coat it, I recommend you get some spray undercoating or a product like "Phil Swift" promotes on TV and spray it on the affected area.
