Evaporative Cooler, AKA Swamp Cooler, Bearing Repair. Pulley Side. Pillow Block Bearings

[@GenralNuisance]

Good idea using the wire brush on the drill. Saved me time.

Dark yes, helpful very much, thanks for knowledge! Been beating on that wheel. Bought a puppy for it. Should have it done tonight

[@Kahn45]

Thanks for the video. The pillow block bearings on my unit are literally fused to the shaft and will not slide off. Now I know they will come off if enough force is applied. I was worried about a hidden Allen wrench screw or something else that I didn't know about.

[@MrUbiquitousTech]

Cleaning the shaft really helps in removal and installation of the new bearings.

[@rynait]

newer evaporative coolers has hollow shafts, aka pipes. I use 5/8 inch fender washer between the 1 inch shaft and puller. 3/4 inch shaft might use smaller washers. use stop collar to find and buy right size washer or nut... by the way, wire brush is good idea to remove most crud off the shaft. , but still need to sandpaper the shaft, to create near smooth surface for oil to lubricate while removing pulley, collar or bearings. for those that is going to replace coolers, and find solid shaft. remove them and keep them as spares. they are keeper (vs hollow shafts).

[@MrUbiquitousTech]

Great information, thanks Rynait!

[@taxiridefun]

Dial makes shaft plug. It comes in different sizes relative to your hollow shaft. Its called blower shaft plug

[@rynait]

@@taxiridefun i checked that dial plug. um amazon sells for 12 dollars (2024 prices). and either a nut or 3 fender washers is cheaper than that plug. wonder if plumbing supply still sell pipe pressure plugs? last check, it is 8 dollars each.

Hey, thanks for the vid. Had to replace the whole shaft, now I can’t get my squirrel cage to sit in the middle and not rub against the edges.. do the pulley and the drive side pillow block touch?

[@MrUbiquitousTech]

The shouldn't, no. That would eventually wear through the pulley as the pillow block bearing is really a bushing and does not spin with the shaft and pulley. You may need to use some thin spacers to get that squirrel cage to center properly. Curious what happened that you needed to replace the entire shaft?

Thanks foe the explanation, much appreciate the helpful tips.

[@MrUbiquitousTech]

Thank you for the kind feedback Marissa!

[@anzaal]

Yes, dark video. But was still able to pick up a few tips. Thanks.

[@MrUbiquitousTech]

Thank you! I'm glad it was some help. The bad lighting was a disappointment.

[@floatingboat3336]

I have a swamp cooler which has two nuts on the blower pulley and I can't remove them as they're stuck. I wish there were a video of how to break the pulley.

[@davessmallenginerevival2847]

We don't have these here in Minnesota. My boy zombie Dave did a video on fixing these

[@MrUbiquitousTech]

Yes, they're not good for much in humid areas, but work pretty good in the dry climates. They struggle if it gets much past 100, but still better than nothing.

[@oscarrivers6949]

I just sprayed WD40 and used a pulley extractor. That's it.

[@MrUbiquitousTech]

Hey, whatever works, right?
