I was recently working on an older Beckett oil burner. I had pulled the motor and blower wheel out to clean them. The owner was there watching as I was working and had told me that the last tech had removed something from "in there" last time. Upon further inspection I noticed that the other company had removed the pump coupling with the "inlet air shut off". I believe that beckett had this type of coupling installed for a reason. Does anyone know why? and also would anyone have a part# for this so I can get a replacement.
Thanks in advance
The previous tech did a fine thing by removing that "thing". Do yourself a favor and don't try to replace it. It can and will be a problem. And is why the previous Tech removed it. It is supposed to be an automatic air shutter that stops air flow through the burner when it isn't running, They often stuck partially open.
Don't replace it.
