Headstock oil pipe plug identification
|
I was doing a oil change of the oil in the headstock. After removing the two pipe plugs located below the two oil cups, I somehow managed to loose one of the plugs! I have spent hours searching for this thing and have not been able to locate it. (No doubt it will turn up in a month AFTER I find a replacement!) It is part # 152 x 73 on the parts list & has a thread of 27 tpi. It's OD at the top is about .400". (Based on the other one that I HAVEN'T lost yet.) I don't see those dimensions listed on any screw charts I have. Can anyone out there tell me specifically what the npt identifier for this screw is? And does anyone have any idea where I might find one?? Thanks, Greg

It looks like a 1/8 npt thread plug.

I think you nailed it amriensr. Shows you what I know about pipe threads. I saw the 1/8 npt having 27 tpi on my screw chart but just looked past it because of the 1/8 designation. I just looked it up on McMaster-Carr and see from the downloadable drawing that the measurements are the same. Thanks for the help! Greg

Greg, that's close to the the standard for 1/8" NPT. You should be able to find those at any good hardware store. 27tpi is definite, OD is .405" and it should be a tapered plug. Pretty sure I have one laying about here somewhere, but finding it would be a bear. If you can stand brass, Home Depot has them on their website. HTH! Bill in OKC William R. Meyers, MSgt, USAF(Ret.)

The only reason I know anything is because I've done it wrong enough times to START to know better

Hope you find it soonest--have you tried using a magnet in botton of the gear box? Better that than crunched in the gears once you try to start it up.
