circulator or motor noise possibly bearings or other

The circulator is making some noise for the past 2 days. There is a grunt for a half second to a second sometimes when the circulator shuts off, although twice so far, it made noise the whole time it ran, which is a minute or so. I had a problem previously just a couple of years ago, a continuous, higher pitched sound, and a local dealer told me there was an oil cup on the circulator, which I found, and after several drops of oil, that was solved, at that time. I just realized that there are also 2 smaller cups on the electric motor. I found those when I tried to read some information on the motor's label. I used several drops of 10-40, and did this several times in the past 2 days. It has made noise only some of the times it ran today. If it should be the bearings, and should the wiring to it need to be disconnected, will the stoker still provide heat? I don't have the money for repairs right now, and the temp is going to zero tonight. I haven't had the money for the past few years to have the dealer come for maintenance, although I emptied the fly ash myself from the chimney.

You have a B&G and they last forever, but the Taco 007 is so much easier to work with. Whatever you do, install isolation flanges on either side of the circulator.

You can gravity feed to a certain extent. Look for your flow control valve. It has a knob on top of it that you open all the way. Most of the time they're frozen, but give it a shot. If you have zone valves, open them manually too. You'll get some gravity flow but it won't be like having a circulator.

Thank you for your quick answer. The flow control must be the valve that is in line just before the circulator? It has the name "Paragon Oil Burner Corp" on it, but I don't see B & G. http://www.flickr.com/photos/truthinrel ... 383243972/

Since I'm in very bad health, I wouldn't be able to replace it myself, but may be able to get a loan this summer. Would the isolation flanges be installed when they remove the pump for repair?

Yes. Fortunately, you have threaded pipe existing.

use straight 30 non detergent oil

I agree, straight oil, not detergent motor oil.

Is the noise coming from the pump or the motor? That motor looks like it could be changed without touching the pump.

Earlier today, it made noise continuously while running, and I quickly walked over, but couldn't tell if it was the pump or motor. It's been quiet for several hours now. I'm hoping I can dodge the bullet until a more financially viable time. I can't remember if my dad had to change it. It's probably 44 years old.
