    Old Schrader tire inflator

    Again, I can’t see my FIL changing out the springs if he didnt have to…and there is air getting into the gauge section… I have checked that.

    Old Schrader tire inflator

    I have the unit hooked to my 3/4 ton pickup with 65 lbs in the tires, so I think should read something, even if not correct.

    Old Schrader tire inflator

    If I hook it up to a tire valve and supply air, with no gauge assembly installed, air from the tire comes out the gauge area, so air is getting to the gauge assembly area. I have seen the gauge function properly in the past, and I don’t think my Father-in-Law would replace the spring if it was...

    No air flows in that configuration.

    You mean completely disassembled?…just supply air hooked up??

    “(Does air flow if you just plug the quick connect into a pressurized line. If not, confirms a valve)” No. Air flows only flows when red button pushed.

    There are no numbers anywhere on the unit.

    Old Schrader tire inflator

    There is no air leaking from anywhere when the supply air is hooked up to the quick disconnect, and the chuck is on the tire valve.

    Old Schrader tire inflator

    Have not messed with the springs…they do seem very “heavy”…takes pliers on the end of the slider to pull it out.

    Old Schrader tire inflator

    It’s not sticky… I’ve cleaned it thoroughly.

    Old Schrader tire inflator

    I have done that… all clear. I’ve run tiny wire through all the passages.

    Old Schrader tire inflator

    Exactly as I remember. My problem is the slider/gauge isn’t moving to show the tires’ pressure. It will air-up a tire just fine.

    Old Schrader tire inflator

    Thanks Mark. This is the only one if these I’ve ever seen. I did see it function when my late Father in Law used it years ago, so I know it did work at one time. I don’t know if it’s been apart before I got it. I was hoping someone on the site might have some experience with it. Not sure where...

    Old Schrader tire inflator

    The small end of the brass piece goes into the top of the valve assembly. Air pressure holds the valve closed, and, when the button is pushed, opens the valve and lets the air travel through the rubber hose, and to the tire.

    Old Schrader tire inflator

    To answer the spring questions, it was in there when I got the inflator, so I dont know if it belongs there or not. The slider did retract by itself when it WAS working. Re: installing the trigger backwards… no, the large diameter end is too big to fit in the inlet valve assembly to open it.

    Old Schrader tire inflator

    Yes, without compressor air hooked up, whether button is pushed or not.

    Old Schrader tire inflator

    No. Button shuts off air as it should, when airring up a tire.. The Cobbler said: it looks like o rings in there? they might be worn? is air by passing and leaking? for giggles. I would try removing the chuck and put air pressure to the line & see what happens? Re: the question above….If air...
