The Name of This Part? Oil Furnace

This part holds the electic motor to my furnace's blower. Does it have a special name because I could not find an exact match at the local hardware store.



Another view in case the other one is not clear enough.



Thank you for any and all help.

joeski, me thinks you got a homemade riggin there??? Why can't you re-use it??

can you get another pic. showing where it's located on the furnace.

Perhaps it adjusts the v-belt tension between the motor and blower ???

Can you try a heating & plumbing supply house for the part?

That is a motor adjustment kit for a belt drive blower. Common part at heating suppliers.

Yes indeed what happened is I have a 1/3 HP electric motor in there from when we bought the house. There has been a 3/4 HP motor sitting in the basement & I realized it's what really should be in the blower compartment. The belt is really loose due to the smaller motor and the missing L shaped screw rod or whatever it is called. I kind of want two L shaped screw rods for when I swap out the motor with a new one. The old owners must have burned out the 3/4 HP and to save money put in a 1/3 HP. I think that would explain why air can't flow to the most distance registers in my house all that powerfully.

Sure thing, here it is. It's under the electric motor.

Why yes it does adjust the tension. I'll have to try a heating & plumbing supply house. Thank you for that tip.

So now I know what to ask for without sounding like a complete dope. Thank you oilman.

BTW, that furnace looks VERY clean, what brand is it?

Let me look. I am pretty sure it's a Royal but I am meaning to get the exact name so I can get some expendable parts.

It looks like an older Oneida Royal, but I wasn't shure.

Don't make the belt too tight. There should be some belt tension recommendations that are pretty much the same for all furnaces.

Check the motor amp draw when you are all done. The speed of the fan will determine the final air flow and amp draw on the motor.

Often looser than you might think if you're thinking like a v-belt accessory drive on a car. My Newmac furnace (also a Delhi blower, probably smaller than yours tho) calls for 1" slack at center (pushing down on the belt, of course.)

Also, you can adjust the speed pulley on the motor if it's adjustable (can't tell, looks like it might be?), and the belt alignment. If you have an adjustable pulley, the manual it may say how many turns out to set it at for your specific furnace.

Not a furnace repairman and I don't play one on TV, just know enough to keep mine going.
