    I am working on a comp for a lowboy.
    The comp model number is coplandmatic
    kae2-0050-iaa
    There is a device about 1/3rd the way up the crankcase that is screwed into the comp.

    It looks like a plug with a screw head in the middle.
    in other words the plug is screwed into the comp and the screw is threaded into the plug.

    When I backed out the screw I see what looks like a rubber plug or something black at the base of the threads.
    The plug is very tight and I do mpt want to force it until I know what it is.

    I want to change / check the oil level and this looks like the best place to drain old oil. I dont see a plug anywhere at the base of the comp.

    Does anyone know what this device is before i take it out??

    Yes this is your oil/crankcase port.
    DANGER!! Remember it is under pressure.
    Remove the gas first! or pump it down, run the service valves in to isolate the system.

    I always use a socket set to remove them, never broke one yet. you must seal the threads when putting back on.

    No, I don't think it's to check for pressure. Boy, I'm not sure what it's for, although I have found them to leak on occassion. Good question! It' gonna bug me til I find out now.

    I've always used leak lock. Never had problems with it - also makes a pretty blue mark on the floor when you step on a tube of it.

    that screw your talking about you can remove and thread in a 3/8 to 1/4 fitting which you can pump oil into with a hand pump. also to remove oil you can remove the crankcase screen and dump it from there. crack the suction a cunt hair to remove all the oil. be careful i mean a thin cunt hair.

    That fitting is a port for the factory to "inject" the oil charge into the crankcase at the factory. You can pull it and put a fitting in there, or replace it. It has no function now that the compressor is out in the field. Take care.

    Yeah - I didn't think it had much of a function. Took several out and replaced with access port. Didn't know exactly what it's purpose in life was. Now I know - thanks.

    You can think of it as the compressor's bellybutton.
