Removed from my 2007 M1151A1. Any ideas what the small soldered-looking lead was for? The oil pressure sensor has Steward Warner stamped into the metal on it.

Could be a small tube they use to purge/gas fill the sensor, then cap it off. Try unsoldering the cap like end piece.

Only if it is no good, un-soldering it will compromise its hermetic seal.

The stem is not for pressurizing it. I read someplace what its there for, but can not for the life of me remember.

That's why it MUST be disassembled, so we can all know. Curious minds want to know....

Well, my curiosity got to me, and I did some further research. One of the NSN documents I found says it is a pressure output port, but not for what purpose. Possibly for a capillary to an actual pressure gage? The doc states "sensor shall have one pressure input connection, one electrical connection, and in some cases a pressure outlet connection".

I seem to remember, when one day I was bored, reading some of the M113 Family TM's. Yeah, that's bored. There was someplace in the -34 TM (?) something about one of the two switches to be used had a extra "Nipple", and one didnt. But the who, what and why I have long forgotten.

That’s for when it’s getting “made” they can verify the pressure is correct. Than it’s pinched off and sealed
