Another HVAC question/favor

I got my blower motor replaced and had the ingenious idea to painstakingly clean all the accumulated gunk off the blades. BIG mistake! Now the blower is unbalanced and vibrates.

Does anyone know where I can get a small quantity of the balancing clips, or what I could use as an alternative?

All I see online are kits that include hundreds of clips.

Did you accidentally move or remove the clips that were on it? I worked in HVAC for years and have cleaned hundreds of dirty squirrelcage blowers but honestly never had to re-balance one.

A handful of patience is worth a bushel of brains...

Here's some cheaper clips:

OR you can use "U" clips for automotive panel fastening, but insert them from the inside of the cage so they won't fly off when it spins up.

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

Yes I did! I must have dislodged the clip when I scrubbed the blades. I tried to figure out where the clip belonged by spinning the blower to locate the heavy side and then put the clip opposite that spot. That only made it worse. Then with a flashlight, I looked between the blades, blade by blade (there are 52 of them) until I finally saw a clean spot where the clip had been. I put the clip there and it's now running smooth as silk.

Thanks

Glad you got it resolved. When I find a small wheel like that out of ballance, I replace the whole wheel.

Bigger blowers, like for large air handlers for hospitals and such that are nearly impossible to remove, those we have ballanced in place, but thats a specialty service we sub contract out.
