Yesterday I was sitting in front of the Swamp cooler and surfing the net when I heard a noise and crystals started shooting out of the cooler's discharge. Good thing I wear glasses while I'm on the computer. Anyway one of the Stalactites that had been growing inside it because of the crappy water down here evidently broke loose and the fan started chopping it up in small crystals and spitting them out at me. After that I heard a weird noise coming from inside the cooler so my project for today was taking it down and cleaning it up. Turns out that in all of this the O-Ring belt that drives the pump got broken which is bad news because I hear the particular cooler is no longer made and you can't get parts from the manufacture anymore. More than likely the same O-Ring can be found from other places where it would likely be used for other applications, but I don't have a clue where that might be?

You think the outside looks bad you should have seen the inside. Some of it you will, but I'd forgotten to take pictures until I'd already started cleaning it up.
Part of the inside.
Shows the broken belt
You can see the broken O-Ring here and fortunately it was still in one piece. Just Me suggested using super glue to reconnect it so I tried it and it seems to be doing ok. Not sure for how long though??? In the mean time I'll be trying to track down a new one. If I can find them I'll probably buy several.
The insides
Note the scale buildup around the float shaft. This was supposed to slide up and down and move a lever showing how much water was in the pan. It was totally cemented in half full position so the only way I knew when it needed more water was when it started blowing hot air.
The inside was full of Stalactites and this just shows a few. I believe this is probably from dissolved calcite because of there being so much down here.
Glued together belt back on.
All of the crap I could get out of it. I really need catchment because rain water down here is about the only thing that would combat this problem. Of course which well the water comes from has a lot to do with it to.
All in all the little Swamp cooler is really amazing and who ever designed it was plenty smart! Its super efficient as far as power consumption goes and the design for pumping water from the sump and delivering it to the pad is very ingenious! Manufactures of residential, commercial and industrial evaporative coolers (Swamp Coolers) could learn a lot from looking at one of these.
