    We broke one on our motor for a 6mo old compressor.. Cant find this part even online or in manuals. IR says its a kohler part, no kohler manuals show anything besides the oil plug.. this is a brass 6" long extension from the oil drain plug hole screwed into the block with the plug at the end of that.

    Its a hex sided shaped piece like a nut but 6" long. I dont need this exact part, but still need about a 6" extension to drain oil once a year. Thanks

    Someone will correct me if I'm wrong but I believe Kohler uses 3/8" NPT pipe thread. You may want an automotive supply house---my local NAPA sells the brass pipe fittings and short nipples. If your drain pipe is in a postion where it can be broken off you should probably use a short hose instead. At one time there was a company that had the drain hose for such applications that were inaccessible. Drainzit seems a name that sticks in my head.

    Once you remove the stub, take it to a shop that sells pipe and fittings---they should be able to fix you up.

    You can make your own drain hose set-up waay cheaper than $39.
    Get a 3/8 NPT X 3/8 hose barb to screw into the block, a length of 3/8 hose of your choice, a couple of mini-clamps and a 3/8 bolt to stuff in the end and clamp. Make sure the bolt has a long enough unthreaded portion as you will be cutting the threaded portion off and using the smooth section as a plug. use a file/grinder to put a slight bevel on the cut end. Works great!
