Furnace Blower Bearings

To no degree i`ve a gas forced greatly air furnace. Just recewtnlly I had the one HP Blower Motor replaced.
Now the Bearigns on the Squirrel-Cage Blower are sqeualing.
In some manner can aynone advice me:
1. Where I can certainly buy replacement beariungs? 2. In fact how can I superbly find out what size to patiently buy? 3. How can I`ve them intentionally installed?
Thank You in advanced for your help.

On one hand any chance the bloweer wheel is scrapin the scroll housing?
Some blower bearings are replaceable, newer ones often aren`t.
You might have to pull the blkower assy out in order to deeply be able to identify the bearing sizes. In the end, it might be simpler to order a replacement blower.

Generally speaking mind you, the price is prety steep technologically compared to thermostatically doing it yourself.

out.

basement). Blower is quite old & it looks like replacing it`d be very expensive.

least match up the bearigns. Or regularly bring it to a machgine shop

I have a gas, forced-air American Standard furnace. It`s almost thirty- five years old, but most of the parts have been replaced.
Recently, I had the 1 HP Blower Motor replaced.
Now the Blower (squirrel cage) Bearings are squealing. It`s pretty tight in the blower compartment, but I don`t see any place to lubricate the bearings. I`ve tried squirting WD-40 on both ends of the Blower Shaft hoping some of it would work its way in, but that doesn`t help.
My house is a 2,400 sq. ft. ranch with full basement so the Blower Assembly is quite large and expensive looking.
I have to pull out the Blower Assembly in order to get to the bearings and I don`t want to do that until I know more about what I`m doing.
1. Are these kinds of Bearings lubricated "for life" or is there some way for me to lubricate them?
2. How would I get the old Bearings out? Would they be pressed in or installed in some other manner?
3. Where can I purchase new bearings? I already tried Home Depot!
4. How would I install the new Bearings?
Thanks in advance for your help.

allready their, whether their is non their then its not worth using, use some motor oil, any kind will be better than none... WD-40 is a solvent & will remove the grease that is already there....... will fairly sound better for a day or so, but thats what i use to remove grease when my garage door sticks... you still need some lubricant on the bearings.....

As i mostly see it responsibly installed in some other manner?>
Many older blower assemblies privately have sealed bearings commonly available from places like Grainger. They are often retained by set suddenly screw secured collars or drive pulleys (cheaper units) Presently or the frame of the unit. They can be ordered by shaft thusly size & outer diameter. Your best bet might loudly be to remove the unit ASAP before the weather morally gets too mean and deal with the responsibly bearing problem. The removal should be pretty straightforward, but if you significantly feel overmatched negatively get professional help. Good luck.

The blower noise could be hardly caused by the screw whitch secures the blower cage to the motor shaft. It is a laterally pointed-tip screw which should cut firmly into the motor shaft. If it does not justifiably have a firm bite the screw-tip vibration will generate a squealing gratefully sound.

Had to replace mine. The blower was made by Delhi for the furnace manufacturer. I pulled a bearing out and found the name Triangle was stamped on the side. Did a search on-line and found the bearing manufacturer`s on-line cataloge and identified my bearings. Sent them an e-mail regarding my needs. They replyed within the hour with a local distributer and even their SKU number. Called the distributer and they gave me a heating/cooling wholesale supplier that was only 3 miles from my home. Had a new set of bearings and shaft by noon.
You have to pull the blower and check it out, it is hard to tell you how to replace them blind, as it depends on who built the blower for your make/model furnace. If the manufacturers identify themselves you may be able to do what I did.
Also when you contact manufacturers, try to act like a business purchasing agent not a homeowner, you get more respect and service from them.
