Changing oil in old sears. No sight or fill plug
by Chase Collis Parker
Old sears compressor unit only
I See you have certainly attempted to answer the question but I am still left confused.
I have no sight glass. I do have a square drain plug like cap and a metal circular plate just above the drain tube.
I also am not sure where to fill this compressor. It has a giant slot that looks removable at first glance but it seems welded. let me know what you think.
Thanks in advance.
