Kohler ch440 14hp compressor motor oil drain extension brass piece?

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!

Unless Kohler has made a change the oil plug thread size is M12x1.5. Stop and remember where this engine is built. I doubt there is anything on it SAE.

I just looked in the Kohler Accessories catalog and it shows 3/8 NPT drain valve fits all models. They show another two adapters but they are only for the CS4-6 and CS8.5-12 respectively.

Yes you are right the acc catalog does show 3/8 NPT but they make no mention of what it fits. Below that they show an M10 to 3/8 adapter for the CH270 which is the little brother of the CH440. I do know the drain plug for the CH395 & the CH440 is slightly larger than that of the CH270 and at one time it was no question M12. I've not physically checked a current production engine but the early 2011 built engine I did have to check was M12. Today it may be 3/8 but I just can't imagine an engine built in China having SAE threads on it but it wouldn't be the first time I was wrong.

Oh crap, yah those CH engines are those new ones. I forgot about those. I thought it was new numbers for the Command Horizontals like CH12 or CH16...

Sorry, yah that catalog might not be updated for those CH engines. Those CS engines are the Yamaha's
