Air leak, what is this part?

[Palm Springs Air Museum]

Hey folks! I'm a volunteer at the WWII air museum in Palm Springs, Ca tasked with maintaining all the museum's ground equipment. The museum had a deuce (M35A2) donated a while ago that I've been working on the last two weeks. I got all the PMs done with info I found here and she's running great.

Only issue now is I could hear an air leak, I listened and found it against the firewall, behind the steering wheel. There's a small hole on the side of the piece pictured below. What is it? Can I plug the hole with a screw? Is something supposed to be hooked up there? I looked through the TMs but couldn't find this part.

Thanks for the help folks, we're supposed to be driving it on a parade soon.

That is your low air switch .

Do not put a screw in the hole.

Replace it with the correct replacement part.

Thanks for the quick response doghead! Ok, so the low air switch itself needs replacement? There's not supposed to be something plugged in there?

Thanks again!

No, that hole is the pressure relief hole. It has a diagram that needs to move freely when the air pressure on the other side changes.

Maybe take a look at this thread it may just need taken apart and cleaned: http://www.steelsoldiers.com/showth...d-help-from-the-old-soldiers&referrerid=19939 .

Got it. Thank you Doghead. I'll try and find the part.

I'll definitely give that a shot first, thank you Blendmaster. After all, if it can be done for free the museum would obviously like that better!

Diagram? What are you posting from your phone?


Sorry couldn't help it.

Carry on.

Actually, I think spellcheck changed it on me!

Either way, I'm laughing!

Just wanted to follow up, I took the switch apart and cleaned it out as detailed in the links. Worked and the switch no longer leaks air. Thanks for the help guys!
