Compressor oil change

I have 20+ yrs old sears 2hp mo.# 106.153991.

Would like to know how much oil it takes?

Howdy:

Difficult to say without actually seeing the unit.

At the base of the compressor head you should find a drain for the compressor oil, and often just above that will be a sight glass to help you determine whether your unit has enough oil.

Here's a pic of the sight glass.

Just below the sight glass is the oil drain for my compressor.

Near the top of the compressor head will be a vented fill port which you unscrew to allow you to pour compressor oil in.

All I do when it's time to change my oil is drain the crankcase through the drain port, replace the drain plug, and then slowly add oil through the fill port while I'm watching the sight glass to make sure I don't overfill.

My guess is that you're dealing with a few ounces of compressor oil to fill yours.

Hope this helps.

Cheers,

Bill

Sight Glass?
by: Curt

Hi. My older Sears Craftsman 2 hp compressor, which is one of the silver -metallic-green ones, also says Sears Best on the label, and also does not have a sight glass. I cannot find my Owners Manual at the present time, and do not know what oil to use to fill it. Does anyone know or remember? I seem to remember it called for motor oil as opposed to compressor oil, but I'm not sure. Thanks.

I'd be surprised if it used motor oil versus compressor oil. I were you, I'd go to the Sears outlet, find a new compressor, ask to look at the manual, and then use the recommendation in there.
