    How much oil is necessary to lubricate the bearings of an evap cooler. I do not think there has been any maintenance performed on this cooler. Ever. I have replaced pads, pump, belt and have now lubed the bearings in the small reserviors on each side of the shaft. It was quiet overnite but I think I must go up on roof again to put more oil in or at least check

    Servicing mine for the first time (new house, obviously hasn’t been maintained in a bit) and the cap near the belt is missing and it looks like the hole where I put oil in is gunked up. What do I do?

    Thank you for this video, and the written instructions as well!. I heard a strange sound when the roof top swamp cooler was on last night. I had the Zoom container in the cabinet I knew, so I looked up your video, and decided to try and fix the problem by myself this morning. The pictures with the red arrows helped a lot! I’ll admit that I was a little nervous, climbing up on the roof this morning to see if I could remove the side panels off, as the cooler is on a slanted roof. But I did it~ and i just wanted you to know that I am a 63 year “young” woman, and i did it myself! Woo hoo~ Thanks again!
