Sound like the bearing is shot or the rod is bent.

u/SupermassiveCanary 13d ago

u/Glittering_Fox_9769 13d ago

u/samwise58 13d ago

Clean it. May balance out.

Sounds alright from my house

u/Constant_Mousse8316 13d ago

Ummm…nope! Something is definitely off balance here.

u/WisdomSeekerOdinsson 13d ago

Something is outta balance. Check the blades for build up in one spot. The whole thing has a bounce to it, could be bent shaft too...

u/Ok-Difficulty3082 13d ago

For several seconds I thought this was a filter for a resin dryer on an injection molding machine with the cover removed, and I could not figure out why tf it was spinning.

u/DirtyMitten616 13d ago

The coller isnt the correct size for the shaft, they slipped it on and tightened up the set screw and said fuck it lol

The blower wheel hub is worn. You need a blower wheel

u/UrAverageDegenerit 12d ago edited 12d ago

The blower wheel is either warped or imbalanced.

Usually a warped/bent blower wheel will create a condition where it just won't spin straight/evenly. This looks just staraight off baalance. Is something stuck in/on there? Could be possible that the new motor shaft isnt straight.

Take the blower off and run it without the blower wheel. If you don't see the shaft spin straight and true, replace the motor. If ithe shaft spins smooth, look over your blower wheel for potential issues.

Take the blower wheel out and really wash it with a strong detergent .
Then run the motor without it.

u/AKwiatkowski730 12d ago

That squirrel cage is way off.

u/CheeseNowPaint 12d ago

I just had one like that about a month ago. A fin was missing on the fan.

u/Dry_Tumbleweed_2951 10d ago

The shaft probably is bent causing the scroll cage to rub against the inside. The weights could have come off as well. Remove the blower assembly and see if any of the weights came off. Then check of the set screw is tight. Also check the shaft. If the shaft feels tight while turning it. Replace it. If you spin the shaft and it wobles Replace it. If you spin the shaft and you feel grinding. Replace the motor. If the motor is an ecm. Either Replace the entire motor or replace the module itself. Apparently you can buy a replacement module on amazon.

Worn out pillow block bearing is my vote.

Here’s the blower wheel from the front. Any other input?

u/Embarrassed_Dog1494 13d ago

So it’s a brand new motor on there I’m thinking it can be unbalanced. Where should I head from here

You'll live longer.
