I was getting a low rumbling sound / vibration out my furnace and replaced the blower motor. It has gotten quieter but it still vibrates a lot. So, I'm assuming the blower wheel is out of balance.
I'm figuring that it's easier to purchase a new wheel than trying to find someone to balance it for me locally (unless someone has a different suggestion). However, I am having trouble finding the part number of the wheel to order a replacement.
I have the RUUD Silhouette II gas furnace and the blower assembly p/n is 61697-52.
Thanks

Have you tried cleaning the fins of the squirrel cage, one by one?
If the blower wheel is just off the floor, you could stuff some rubber under the housing to deaden (as a damper) the sound. I have done this to quiet noisy bath fans also. I also once dampened the vibration to a turntable in a swaying beach house on pilings, by hanging the turntable by piano wire from the open cathedral ceiling beams and then cutting slits in heavy rubber discs and slipping them onto the wires and this stopped the tone-arm skipping! Shows what some rubber can do.

Thanks for the suggestion and it sounds like ingenuity hard at work. But cleaning the fins one-by-one was what made the vibration worse. There was some plaster on some of the fins and upon removing it, the vibration worsen. I guess it was helping to keep the wheel balanced?
I already have a rubber door stop under the blower to help deaden the vibrations but I figure if I don't eventually balance the wheel, I'll wear out the bearings on the new motor sooner than later.
But I'll have to remember the idea about the turntable...except that I doubt I'll ever take mine out storage again.

Id pull the blower out and go over the blades on the squirrel cage again . That might do it you could have missed on or two.

This is why we will not let a builder run our units in the home till they are done.
