How Much Oil for this Air Compressor Pump

[apittmanii]

Hello- I purchased the air compressor depicted in the attached photos. It needed a new pressure switch which was an easy replacement. The compressor is ugly but it works.

Drained the oil to lay it horizontally in my truck.

My question is this: There is no clear window on the pump and I can’t locate a manual. How much oil do I fill in this compressor? I assume all the way up to the fill hole.

Thank you in advance.

you would fill that to just under overflowing if there's no dipstick on that plug
looks like the drain plug gasket is toast too

Off hand I'd say to the top of the fill plug. You may find a manual by searching the model number,

^ Yes on the above. Fill to the top of the fill plug threads. If you imagine a sight glass (like my similar pump has) on the side of the crankcase, that puts the oil level right about in the middle of it. There is a dipper on the end of the connecting rod that scoops up the oil and splashes it around inside - the oil has to be just high enough for that to happen.

I’ve got a very similar compressor, that white cap has a dipstick on it. It has 2 lines for the correct level.

That white cap looks like it has a dipstick attached. Take a looks and let us know.
