I've got an old Eagle compressor, about 40 gallons that I gave to my SIL a year or so ago and just got back because it "keeps tripping the breaker." Well, the connecting rods were seized to the crank. I wound up getting them off with some heat and found that a finger one of the rods was missing. with the oil level at the center of the site glass, the finger barely -- just barely, touches the oil in the sump. I presume that the fingers are designed to splash lubricate some part of the internals, but I really don't see how they're going to get oi all the way up on the crank or to the pins in the pistons. I was able to clean up the rod surfaces that connect to the crank and they rotate freely now. I JB welded on the broken off finger. I'm assuming it seized because it was low or out of oil. I don't know the HP, but its got a hefty 15a electrical motor operating the pump.
So, how much oil going forward? Are those fingers on the rods really supposed to lubricate the rotating assembly? I realize its relatively low RPMs and that its probably some overseas POS, but still... The bottom of the connecting rods sit several inches above the pool of oil in the sump. I think the crankshaft counter weight sloshes through the oil pool, and that probably accounts for most of the lubrication, but I'm wondering how much oil I can add and not create a problem. Any idea? If I had a manual, I assume it would say sight glass is the mark, but it seems pretty low.
